    Medicare Program; Additions To and Deletions From the Current 
    List of Covered Surgical Procedures for Ambulatory Surgical Centers
    
    AGENCY: Health Care Financing Administration (HCFA), HHS.
    
    ACTION: Final notice with comment period.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This final notice with comment period implements section 
    1833(i)(1) of the Social Security Act, which requires, in part, that 
    the list of covered ambulatory surgical center (ASC) procedures be 
    reviewed and updated at least every 2 years.
        This notice announces the specific additions to and deletions from 
    the list of surgical procedures for which facility services are covered 
    when the procedures are performed in a Medicare-participating ASC, as 
    well as the assigned payment groups for each addition. The notice also 
    announces a change in our criteria for deleting procedures from the ASC 
    list. This notice also responds to public comments received in response 
    to our proposed notice published December 14, 1993 (58 FR 65357). In 
    that notice, we requested comments on the proposed additions to and 
    deletions from the list of covered surgical procedures for ASCs; the 
    proposed quantitative change in our deletion criteria; the development 
    of alternatives to the proposed quantitative deletion criteria; and the 
    assignment of payment groups for each addition.
        Finally, this notice solicits public comment on certain additions 
    to and deletions from the ASC list that had not been suggested in our 
    December 1993 proposed notice. It also solicits public comment on the 
    assignment of payment groups for certain new procedure codes.
    
    EFFECTIVE DATE: The effective date of this notice is February 27, 1995, 
    except as follows. The effective date for the procedures that are being 
    deleted from the ASC list, as listed in Addendum A, is April 26, 1995.
        The effective date for the procedures that were deleted from the 
    list as a result of deletions from the 1992 Physicians' Current 
    Procedural Terminology (CPT), as listed in part 1 of Addendum C, is 
    March 31, 1992. The effective date for the procedures that were added 
    to the list as a result of additions to the 1992 CPT, as listed in part 
    2 of Addendum C, is January 30, 1992.
        The effective date for the procedures that were deleted from the 
    list as a result of deletions from the 1993 CPT, as listed in part 3 of 
    Addendum C, is July 7, 1993. The effective date for the procedures that 
    were added to the list as a result of additions to the 1993 CPT, as 
    listed in part 4 of Addendum C, is January 1, 1993.
        The effective date for the procedures that were deleted from the 
    list as a result of deletions from the 1994 CPT, as listed in part 5 of 
    Addendum C, is April 11, 1994. The effective date for the procedures 
    that were added to the list as a result of additions to the 1994 CPT, 
    as listed in part 6 of Addendum C, is January 1, 1994.
    
    COMMENT DATES: We are requesting public comment on the addition of, and 
    assignment of payment groups for, the following new CPT codes, which 
    are listed in Addendum B (since these codes were not suggested in our 
    December 1993 proposed notice): CPT codes 29804, 43259, 51040, 52450, 
    56309, 56316, 56317, 56351, 56356, and 64421. We are requesting public 
    comment on the appropriateness of the deletion of the CPT codes listed 
    in Addendum C, part 5, and the deletion of CPT code 36522, listed in 
    Addendum A, because these codes were not suggested in our December 1993 
    proposed notice. Additionally, we are requesting public comment on the 
    appropriateness of the addition of, and assignment of payment groups 
    for, the CPT codes listed in part 6 of Addendum C. Comments will be

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        Section 934 of the Omnibus Reconciliation Act of 1980 (Public Law 
    96-499), enacted on December 5, 1980, amended sections 1832(a)(2) and 
    1833 of the Social Security Act (the Act) to authorize the Secretary to 
    provide benefits for services furnished in an ambulatory surgical 
    center (ASC). Section 1833(i)(1) of the Act requires the Secretary to 
    specify, in consultation with appropriate medical organizations, 
    surgical procedures that, although appropriately performed in an 
    inpatient hospital setting, can also be performed safely on an 
    ambulatory basis. The report accompanying the legislation explained 
    that the Congress intended that procedures currently performed on an 
    ambulatory basis in a physician's office, which do not generally 
    require the more elaborate facilities of an ASC, should not be included 
    in the list of covered procedures (H.R. Rep. No. 1167, 96th Congress, 
    2d Session 390 (1980), reprinted in 1980 U.S.C.C.A.N. 5526, 5753).
        On August 5, 1982, we published a final rule in the Federal 
    Register (47 FR 34094) to establish Medicare coverage for ASC services 
    at 42 CFR part 416. These regulations were amended on November 14, 1986 
    (51 FR 41351), June 12, 1987 (52 FR 22454), and April 7, 1988 (53 FR 
    11508). We implement the [[Page 5186]] provision requiring the 
    Secretary to publish a list of procedures covered in an ASC through 
    issuance of periodic notices in the Federal Register.
        Section 9343 of the Omnibus Budget Reconciliation Act of 1986 (OBRA 
    '86) (Public Law 99-509), enacted on October 21, 1986, amended section 
    1833(i)(1) of the Act to require that the ASC list of procedures be 
    reviewed and updated by April 21, 1987, and not less often than every 2 
    years thereafter. As a result, we published updates in the Federal 
    Register on April 21, 1987 (52 FR 13176), June 1, 1989 (54 FR 23540), 
    and December 31, 1991 (56 FR 67666). These updates supplement the 
    original list of covered ASC procedures published on August 5, 1982 (47 
    FR 34099).
        In line with the Congressional intent, current regulations (42 CFR 
    416.65(a)) list the following general requirements regarding the range 
    of covered ASC services:
         Procedures on the list are commonly performed on an 
    inpatient basis but, consistent with accepted medical practice, also 
    may be performed in an ASC.
         The list excludes procedures that are commonly performed, 
    or may be safely performed, in a physician's office.
         Procedures are limited to those requiring a dedicated 
    operating room and generally do not require an overnight stay.
         The list does not contain procedures excluded from 
    Medicare coverage.
        In addition, current regulations (Sec. 416.65(b)) list the 
    following specific requirements:
         Covered surgical procedures are limited to those that do 
    not generally exceed--
    
      + A total of 90 minutes operating time; and
      + A total of 4 hours recovery or convalescent time.
    
         If the covered surgical procedures require anesthesia, the 
    anesthesia must be--
      + Local or regional anesthesia; or
      + General anesthesia of 90 minutes or less duration.
         Covered surgical procedures may not be of a type that--
    
      + Generally result in extensive blood loss;
      + Require major or prolonged invasion of body cavities;
      + Directly involve major blood vessels; or
      + Are generally emergency or life-threatening in nature.
    
        Currently, ASC covered procedures are classified according to an 
    eight group payment classification system, as follows:
    
      Group 1--$295
      Group 2--$395
      Group 3--$453
      Group 4--$558
      Group 5--$637
      Group 6--$750 ($600+$150)
      Group 7--$883
      Group 8--$880 ($730+$150)
    
    (The $150 payment allowance in Groups 6 and 8 is for intraocular lenses 
    (IOLs).) A ninth payment group allotted exclusively to extracorporeal 
    shock wave lithotripsy (ESWL) services was established in the notice 
    with comment period published December 31, 1991 (56 FR 67666). The 
    decision in American Lithotripsy Society v. Sullivan, 785 F. Supp. 1034 
    (D.D.C. 1992) prohibits us from paying for these services under the ASC 
    benefit at this time. ESWL payment rates are the subject of a separate 
    Federal Register proposed notice, which was published October 1, 1993 
    (58 FR 51355).
        The ASC facility payment for all procedures in each group is 
    established at a single rate adjusted for geographic variation. This 
    prospectively determined facility group rate does not include 
    physicians' fees and other medical items and services (for example, 
    prosthetic devices, except IOLs) for which separate payment is 
    authorized under other provisions of the Medicare program. Rather, the 
    rate is a standard overhead amount that covers the cost of services 
    such as nursing, supplies, equipment, and use of the facility.
        Section 9343 of OBRA '86 amended section 1833(i)(2)(A) of the Act 
    to require updating of the ASC payment rates annually beginning no 
    later than July 1, 1987. In addition, so that the most current wage 
    index values can be used in determining payment amounts for ASC 
    facility services, annual ASC payment rate updates are implemented 
    concurrently with the annual update of the inpatient hospital 
    prospective payment system (PPS) wage index published in the Federal 
    Register.
        Section 13531 of the Omnibus Budget Reconciliation Act of 1993 
    (OBRA '93) (Public Law 103-66), enacted on August 10, 1993, prohibited 
    the Secretary from providing for any inflation update in the ASC 
    payment rates for fiscal year 1995. In addition, the legislation 
    reduced the allowance for an IOL furnished during or subsequent to 
    cataract surgery performed in an ASC from $200 to $150 beginning 
    January 1, 1994, and before January 1, 1999. As a result, the payment 
    rates and the $150 payment allowance for an IOL in Groups 6 and 8 will 
    remain the same in fiscal year 1995.
        In our December 1991 notice, we stated that changes in ASC payment 
    rates and the list of ASC covered procedures would be implemented 
    concurrently during the years in which both are updated (56 FR 67677). 
    The ASC payment rates and the ASC procedure list were updated 
    concurrently for the first time effective for ASC services furnished 
    beginning December 31, 1991. Because of the OBRA '93 freeze on the ASC 
    payment rates for fiscal year 1995, the ASC payment rate update notice 
    will not be published this year although we will instruct our carriers 
    to adopt the fiscal year 1995 hospital inpatient PPS wage index, 
    published in the Federal Register on September 1, 1994 (59 FR 45330), 
    to adjust payment rates for regional wage differences.
    
    II. Provisions of the Proposed Notice
    
        In the proposed notice, which was published December 14, 1993 (58 
    FR 65357), we proposed specific procedures for addition to or deletion 
    from the ASC list. These proposed changes were the result of our 
    consideration of data on site of service from the National Claims 
    History File (NCHF) and general correspondence received from the public 
    and medical community over the few years preceding publication of the 
    proposed notice. (The NCHF is a database maintained by our Bureau of 
    Data Management and Strategy. The data in the NCHF are derived from 100 
    percent of the Medicare Part A and Part B claims processed.) For each 
    proposed addition, we proposed a payment group based on payment rates 
    for codes on the existing ASC list, and in the same Physicians' Current 
    Procedural Terminology (CPT) grouping, that are similar in surgical 
    method and resource consumption. (The CPT is published annually by the 
    American Medical Association.)
        With the advice of our medical staff, we proposed to add surgical 
    procedures that are performed in ASCs and meet certain standards 
    contained in existing regulations. We also proposed to modify our 
    criteria for deleting procedures from the ASC list. As the practice of 
    medicine has changed over the years, procedures that were at one time 
    commonly performed on an inpatient basis gradually have shifted to the 
    hospital outpatient department (OPD) as the most common site of 
    service, and a few eventually have shifted to the physician's office as 
    the primary site of service. Procedures that are not performed on an 
    inpatient basis or are primarily performed in a physician's 
    [[Page 5187]] office no longer meet the conditions specified in 
    regulations. This development results in a corresponding change in 
    claims data to lower inpatient and higher physician's office site-of-
    service performance percentages, and these procedures no longer meet 
    our 20/50 site-of-service criteria. By 20/50 site-of-service criteria, 
    we mean that if a procedure is performed on an inpatient basis 20 
    percent of the time or less, or in a physician's office 50 percent of 
    the time or more, it should not be covered when performed in an ASC. We 
    may make exceptions and override the criteria if we believe the data 
    are inaccurate or if there are medical reasons to override the data.
        If we had strictly applied the 20/50 criteria to our current ASC 
    list without making exceptions, we would have been proposing deletion 
    of a number of procedures, such as cataract removal, that we believe 
    are appropriate to the ASC setting. We were also concerned with what 
    might be termed a ``ping-pong'' situation; that is, adding a procedure 
    during one update with 49 percent physician's office performance and 
    then deleting it during the next update if it reached 51 percent 
    physician's office performance. Consequently, we proposed the following 
    criteria for deleting a procedure from ASC coverage: The combined 
    inpatient, OPD, and ASC site-of-service percentage is less than 46 
    percent of the total volume; and either--
         The procedure is performed 50 percent of the time or more 
    in a physician's office; or
         The procedure is performed 10 percent of the time or less 
    in an inpatient hospital setting.
        This proposed change would allow the site of service for procedures 
    in the physician's office to grow from below 50 percent (when it is 
    added) to as high as 54 percent, as long as the percentage of time the 
    procedure is performed in a facility with a dedicated operating room 
    remains at 46 percent. Similarly, the criteria allow procedures to move 
    from an inpatient hospital site of service to an OPD site of service 
    and still remain on the ASC list. To determine whether a procedure 
    should be added to the ASC list, we indicated that we would continue to 
    use the 20/50 site-of-service criteria.
        We incorporate annual revisions of the CPT into our list of 
    procedures covered in an ASC. Therefore, we also proposed for public 
    comment the procedure codes that were added to or deleted from the ASC 
    list through changes to the Medicare Carriers Manual as a result of 
    updates of the 1992 and 1993 editions of the CPT.
        In addition, we proposed to remove from the ASC list five CPT codes 
    that involve procedures relating to the usage of implantable infusion 
    pumps not covered by Medicare.
    
    III. Analysis of and Responses to Public Comments
    
        In our December 1993 proposed notice, we requested comments on the 
    proposed quantitative change in our deletion criteria; the development 
    of alternatives to the proposed quantitative deletion criteria; 
    proposed additions to and deletions from the ASC list; and the 
    assignment of payment groups for each addition. In response, we 
    received 558 timely public comments from 191 urologists, 107 ASCs, 52 
    anesthesiologists, 50 patients, 30 ophthalmologists, 26 psychiatrists, 
    28 plastic surgeons, 14 obstetrician/ gynecologists, 8 
    gastroenterologists, 6 dermatologists, 19 professional/medical 
    societies, and 27 others (that is, neurologists, attorneys, 
    radiologists, a Medicare director, a podiatrist, an accountant, 
    otolaryngologists, a supplier, and an oncologist). A summary of these 
    comments and our responses to them follows:
    
    Criteria for Determining Procedures for Coverage in an ASC
    
        In our December 1993 proposed notice, we announced our intention to 
    apply alternative utilization threshold criteria for deleting 
    procedures from ASC coverage. That is, rather than deleting procedures 
    that fall below the current coverage threshold, we proposed alternative 
    criteria for deleting procedures that examine the incidence of 
    dedicated operating room use (combined ASC, OPD, and inpatient site-of-
    service utilization) in determining if a procedure that has dropped 
    below the 20 percent inpatient criteria should remain covered in an 
    ASC. We specifically solicited comments on the alternative criteria. 
    However, we did not receive any comments on this issue.
        In addition, we requested comments on developing alternatives to 
    the quantitative criteria we currently use in developing the ASC list. 
    We received 64 comments regarding our current site-of-service-based 
    criteria. The commenters included 35 ASCs, 16 urologists, 4 
    anesthesiologists, and 9 professional societies.
        Comment: Several commenters stated that our criteria are outdated, 
    reflecting a period when surgery was rarely performed on an outpatient 
    basis. They noted an absence of scientific or medical literature 
    supporting the thresholds used. Therefore, they believed the criteria 
    are arbitrary.
        Response: The inpatient and physician's office utilization 
    thresholds serve as a reasonable interpretation of the statutory 
    language ``appropriately performed on an inpatient basis.'' That is, we 
    believe that if a procedure is performed at least 20 percent of the 
    time on an inpatient basis and no more than 50 percent of the time in a 
    physician's office, we can reasonably regard the procedure as 
    appropriate to the inpatient setting. Section 1833(i)(1) of the Act 
    requires the Secretary to ``specify those surgical procedures which are 
    appropriately (when considered in terms of the proper utilization of 
    hospital inpatient facilities) performed on an inpatient basis in a 
    hospital but which also can be performed safely on an ambulatory 
    basis'' in an ASC. Thus, section 1833(i)(1) of the Act is clear that 
    procedures included on the ASC list of covered procedures must be those 
    that are appropriately performed on an inpatient basis.
        In developing regulations that implemented section 1833(i)(1) of 
    the Act, we prepared the criteria set forth at 42 CFR 416.65 (``Covered 
    surgical procedures''). Those regulations specify conditions for 
    coverage of procedures that are commonly performed on an inpatient 
    basis but may be safely performed on an outpatient basis. These 
    conditions include requirements such as operating room time not 
    exceeding 90 minutes, recovery period not exceeding 4 hours, limited 
    blood loss, and limited invasion of body cavities. We believe that 
    these criteria reasonably meet the conditions set forth in the 
    legislation.
        For several years, we used only the qualitative criteria described 
    in the regulations. We added procedures to the list based on 
    physicians' review of procedures recommended by medical organizations. 
    This system resulted in only a limited number of procedures being added 
    to the ASC list.
        Patient variability made it difficult for our physicians to 
    accurately determine procedures that should be added to the list, 
    especially procedures that are close to the cut-off of the qualitative 
    criteria; for example, a surgery time of 2 hours or a recovery time of 
    4\1/2\ hours. A given procedure varies with patient condition. That is, 
    a procedure that may be accomplished in 90 minutes for one patient may 
    take 120 minutes for another.
        In developing the 1987 update of the ASC list, we determined that a 
    numerical threshold based on site of service should be used to assist 
    us in implementing section 1833(i)(1) of the [[Page 5188]] Act. We 
    believed criteria based on site of service, as shown in our current 
    claims data, would yield a range of procedures for review by our staff 
    of physicians to include on the ASC list. In this way, we would have 
    support for the addition of procedures physicians generally perform on 
    an inpatient basis. Our physicians then review the complete list of 
    procedures that meet the threshold criteria and determine which meet 
    the qualitative criteria in our regulations.
        We acknowledge that utilization of outpatient surgical settings has 
    increased considerably since we first initiated the threshold criteria 
    in 1987. For this reason, we proposed altering the criteria for 
    deleting procedures from the ASC covered procedures list. We thus 
    recognize some movement to the outpatient setting without eliminating 
    coverage. However, once a procedure is performed in a physician's 
    office the majority of the time and does not require the setting of an 
    ASC, OPD, or inpatient hospital 46 percent of the time, we believe that 
    section 1833(i)(1) of the Act requires that we delete ASC coverage of 
    the procedure.
        When preparing the December 1993 proposed notice, we considered 
    policy alternatives and discussed reverting to physician judgment 
    exclusively. However, we believe that this option is too subjective, 
    leaving policy decisions solely to the discretion of a few. If we were 
    challenged by another physician's opinion, we could be presented with 
    the situation of two equally qualified professionals with different 
    opinions. Thus, we believe that some objective criteria are essential 
    in determining coverage of procedures in an ASC.
        Comment: Some commenters believed that the Common Working File 
    (CWF) is inadequate for assessing site of service. (The CWF is a 
    Medicare Part A and Part B benefit coordination and prepayment claims 
    validation system that uses localized databases maintained by 
    designated carriers. The CWF indicates site of service for surgical 
    procedures.) The commenters believed that the data produced are skewed, 
    especially for periods before the last 2 years when site-of-service 
    data had been emphasized. They stated that CPT coding practices vary 
    greatly, resulting in the same procedure being coded differently in 
    different areas.
        Response: We acknowledge that the early data using site-of-service 
    codes contained errors. Those data may have skewed results, 
    particularly for low-volume procedures or procedures near the threshold 
    levels. Consequently, our criteria allow for exceptions if the data 
    appear flawed, or our physicians, after consultation with medical 
    societies and local experts, believe a procedure is appropriate to the 
    inpatient setting despite the data. Under this exceptions authority, we 
    have retained procedures such as cataract extractions, which have not 
    met the inpatient criterion for several years. In addition, the public 
    has an opportunity to comment, through our rulemaking process, on what 
    they believe are errors in the data.
        With regard to the issue of varying CPT coding practices, we 
    acknowledge that not all physicians code a particular procedure 
    identically. Unfortunately, this variation in coding is often the 
    result of an attempt to maximize Medicare payment to the physician for 
    the procedure, rather than the result of ambiguous coding guidelines. 
    While this upcoding occasionally affects the ASC list, we attempt to 
    identify these situations and retain the procedure on the ASC list 
    through the exceptions authority if the procedure is appropriate to the 
    inpatient setting. We ask physicians to encourage their peers to code 
    procedures appropriately to avoid these situations.
        Comment: One commenter believed we should use a 10 percent 
    inpatient criterion for adding procedures to the list. The commenter 
    also suggested that any procedure generally requiring the prior or 
    concurrent administration of general, spinal, or regional anesthesia, 
    or of sedation or analgesia sufficient to compromise a patient's 
    protective reflexes, be included on the ASC list regardless of 
    utilization data.
        Response: The type of anesthesia necessary for a given procedure 
    varies among patients. Some patients have very low pain thresholds, 
    special psychological needs, or anatomical conditions warranting a 
    higher level of anesthesia than others. We encourage every physician to 
    use his or her judgment in selecting the appropriate anesthesia. We do 
    not encourage the use of anesthesia in settings not appropriately 
    equipped for emergency situations.
        The need for an operating room setting for a particular patient is 
    not equivalent to a procedure meeting the conditions of section 
    1833(i)(1) of the Act for ASC coverage. As discussed above, section 
    1833(i)(1) requires that we cover procedures in an ASC only if they are 
    appropriately performed on an inpatient basis. Thus, if a patient 
    requires a higher degree of anesthesia than is reflected in the 
    utilization data, that procedure would be covered in an OPD, or, if 
    necessary, in an inpatient hospital setting.
        We had considered revising the criterion for adding procedures on 
    the ASC list to 10 percent inpatient utilization. However, we believe 
    that the current threshold of 20 percent represents a reasonable 
    portion of use necessary to meet the statutory requirement of 
    appropriately performed on an inpatient basis.
        Comment: One commenter believed that our physician's office 
    threshold should focus on the percentage of physicians performing the 
    procedure in the office, rather than the percentage of procedures being 
    performed in the office.
        Response: We do not believe that the percentage of physicians 
    performing a procedure in their offices, rather than the total site-of-
    service utilization data, is preferable for determining ASC coverage. 
    Many physicians perform a given procedure only once or twice during the 
    year. These physicians are not likely to maintain the specialized 
    equipment necessary to perform the procedure in their offices, and, 
    therefore, are not likely to perform it in that location. Also, a 
    particular physician may not be proficient with the procedure and may 
    desire to perform the procedure where there are resources available, 
    should a mishap occur.
        We do not believe that a large percentage of physicians performing 
    a few procedures should serve as the basis for determining whether a 
    procedure meets the conditions of section 1833(i)(1) of the Act. It is 
    difficult to ignore the data indicating a procedure is commonly 
    performed in a physician's office, if only relatively few physicians 
    perform the majority of the procedures, in favor of those physicians 
    performing the same procedure on an occasional basis. In addition, 
    accurately determining the percentage of physicians performing a 
    procedure in their offices would be extremely difficult.
        Comment: One commenter believed that the criteria result in a 
    competitive advantage to an OPD over an ASC. The commenter recommended 
    that if a procedure can be safely performed in an OPD, it can be safely 
    performed in an ASC and should be on the list.
        Response: Section 1833(i)(1) of the Act established criteria for 
    coverage in an ASC when the ASC services were added as a Medicare 
    benefit in 1980. Section 1833(i)(1) of the Act requires that we develop 
    a list of procedures covered in an ASC and base the list on procedures 
    that are appropriately performed on an inpatient basis.
        These requirements for ASC coverage are not applicable to an OPD. 
    The original Medicare statute provided for coverage of all services 
    furnished by an [[Page 5189]] OPD, but it did not provide for any 
    limitations on the appropriateness of a procedure for the inpatient 
    setting or for the establishment of a list of procedures. Consequently, 
    it is reasonable to expect that procedures covered in an OPD will not 
    always be the same as procedures covered by section 1833(i)(1) of the 
    Act. For example, there is no limitation on an OPD to perform only 
    surgical procedures. Thus, adopting the suggestion would result in a 
    significant expansion of the ASC benefit beyond that contemplated in 
    section 1833(i)(1).
        Comment: One commenter believed that operating and recovery time 
    usage are inaccurate indicators of the complexity of procedures, and 
    clinical criteria should be used instead. The commenter stated that the 
    overriding guideline should be that the patient can return home by the 
    close of the business day.
        Response: We recognize the commenter's concern that clinical 
    criteria be considered in establishing the ASC list. However, we 
    believe that general operating and recovery times are related to 
    clinical criteria. That is, we do not look at operating and recovery 
    room times on an isolated basis, but rather review the clinical 
    information indicating that generally patients require 90 minutes or 
    less operating time and 4 hours or less recovery time. We believe that 
    these criteria are good indicators of a patient's ability to go home by 
    the close of the business day. Procedures requiring longer times than 
    those included in the criteria are unlikely to be completed within the 
    business day. For example, we would expect that patients arrive at 
    least 1 hour before the surgery begins. Thus, our criteria involve 6\1/
    2\ hours of an 8 hour work day, allowing 1\1/2\ hours leeway for any 
    delays.
        Comment: Some commenters believed that the Medicare program should 
    allow for overnight stays in an ASC. The commenters stated that, 
    initially, the inclusion of overnight stays could be part of a study 
    with a Medicare review at the annual certification survey or a review 
    by the Peer Review Organization (PRO).
        Response: Section 1833(i)(i) of the Act provides for coverage of 
    surgical procedures that, in addition to other criteria, ``can be 
    performed safely on an ambulatory basis.'' We believe section 
    1833(i)(1) is clear that coverage of overnight stays under the ASC 
    benefit is prohibited. Rather, ambulatory care implies care that is 
    furnished with the patient going home by the end of the day. Thus, it 
    would require a legislative change to extend Medicare ASC benefits to 
    overnight care or recovery care.
        Our Office of Research and Demonstrations has the authority to 
    waive certain portions of the statute in order to study alternative 
    means of furnishing or paying for services under the Medicare program. 
    We solicit research proposals annually through a notice published in 
    the Federal Register, and projects are selected on a competitive basis. 
    ASCs are welcome to submit their research proposals for consideration 
    under the routine solicitation process.
        Comment: One commenter suggested that Medicare develop an 
    alternative list of procedures that could be covered in an ASC upon 
    precertification from the fiscal intermediary or the PRO. Another 
    commenter suggested we establish ``severity levels'' that allow 
    physician discretion for procedures and settings. The commenter 
    believed that, as certain CPT codes are deleted from the list, the 
    codes should continue to justify a facility fee if certain ``severity 
    levels'' and health risks apply. The same commenter stated that these 
    codes can be billed with a modifier or with the accompanying 
    International Classification of Diseases, Ninth Revision, Clinical 
    Modification (ICD-9-CM) diagnostic codes explaining the patient's 
    condition. Yet a third commenter suggested that an ASC site of service 
    could be justified by evaluating certain parameters. The commenter 
    believed that an outpatient setting, rather than a physician's office, 
    would be appropriate if certain conditions, such as intravenous therapy 
    or expensive equipment, are involved.
        Response: For a procedure to be covered in an ASC, the procedure 
    must meet the conditions set forth in section 1833(i)(1) of the Act. 
    That is, procedures covered in an ASC must be appropriately furnished 
    on an inpatient basis but also can be performed safely on an ambulatory 
    basis.
        There are some patients who, because of medical conditions, may 
    require surgery in an ASC-like setting, that is, a dedicated operating 
    room with a recovery area and emergency equipment, etc. Although some 
    patients may require this setting because of health status, the 
    procedure may still not meet the conditions for ASC coverage set forth 
    in section 1833(i)(1) of the Act. That is, a procedure that is 
    routinely performed in a physician's office is still not appropriate 
    for the inpatient setting, although an occasional patient requires 
    hospitalization for the procedure. Precertification of the specific 
    needs of the patient does not make the procedure inpatient. Rather, it 
    means that a particular physician attests that a patient requires a 
    more intensive setting for the procedure.
        Moreover, there are no commonly accepted severity levels that we 
    could easily accommodate in the development of the list of covered 
    procedures for ASCs. Section 1833(i)(1) of the Act does not provide for 
    an evaluation of individual patient conditions, such as severity, in 
    the development of the ASC list. The list is required to reflect common 
    practices. We would not expect physicians to perform procedures in 
    offices not adequately equipped for the procedure. These cases should 
    be handled in an OPD if the procedure is not on the ASC list.
        Comment:  One commenter stated that we should be aware that our ASC 
    list is used by virtually all Medicaid programs in the U.S., as well as 
    private insurers.
        Response: The Medicare ASC list is not intended to be a list of all 
    procedures performed in an ASC. Rather, it is a list of procedures that 
    meet the requirements of section 1833(i)(1) of the Act. When we develop 
    our list, we consider section 1833(i)(1) and the appropriateness of a 
    given procedure for the Medicare population. For example, our list 
    contains no pediatric procedures. Yet these procedures would be 
    appropriate for Medicaid patients.
        The Medicare program cannot be responsible for the actions of third 
    party payers. Any programs that have decided to adopt our list should 
    do so with appropriate modifications, keeping in mind the limitations 
    of section 1833(i)(1) of the Act and the requirements of their 
    customers.
        Comment:  Another commenter requested that we consider a list of 
    approved procedures and minor surgeries that can be safely performed in 
    a physician's office. The commenter believed that this list should 
    contain no procedures requiring anesthesia or sedation of any kind.
        Response: We do not believe it is appropriate to develop a list of 
    procedures that can safely be performed in physicians' offices. 
    Physicians' offices vary significantly in equipment and staffing. We 
    have not established standards for physicians' offices, nor do we 
    survey them. Because there is broad variability in these offices, the 
    development of a list is likely to result in the exclusion of 
    procedures that are safely performed in some locations and the unfair 
    restriction of physicians' practices. We believe that physicians will 
    not perform a procedure in their offices unless they maintain 
    appropriate facilities, equipment, and staff to perform the procedure 
    safely.

    Additions to the List
    
        The proposed list of additions in our December 1993 proposed notice 
    received no negative comments. The few comments we received were 
    positive and were written as an introduction to letters opposing our 
    proposed deletions.
    
    Additional Suggestions for Coverage
    
        We received several comments recommending coverage for procedures 
    not proposed for addition to the list. Some comments included 
    procedures we addressed in the December 1993 proposed notice as having 
    been previously considered. The following section, arranged by body 
    system, responds to those comments.
    
    Integumentary System
    
        Comment: Some commenters proposed the addition of the following 
    procedures to the list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    15820.  Blepharoplasty, lower eyelid.                                   
    15821.  Blepharoplasty, lower eyelid; with extensive herniated fat pad. 
    18522.  Blepharoplasty, upper eyelid.                                   
    15823.  Blepharoplasty, upper eyelid; with excessive skin weighting down
             lid.                                                           
    ------------------------------------------------------------------------
    
        Response: We proposed to add these procedures to the ASC list in 
    1991. Based on our review of the public comments and the advice of our 
    medical staff, we decided not to add these procedures to the list 
    because they are commonly performed for cosmetic purposes. Section 
    1862(a)(10) of the Act prohibits payment for cosmetic surgery or 
    expenses incurred in connection with cosmetic surgery. We recognize 
    that there are circumstances when surgery on the eyelids is performed 
    for noncosmetic reasons; for example, impairment of vision. Often these 
    circumstances require a more complex procedure than a simple 
    blepharoplasty. For that reason, we include on the ASC list all of the 
    blepharoptosis repair codes (CPT codes 67901 through 67908). These 
    procedures are performed less commonly for cosmetic purposes than the 
    blepharoplasty codes.
        We also reviewed the most recent data regarding site of service and 
    noted that the blepharoplasty procedures are performed infrequently on 
    an inpatient basis (3 to 5 percent of blepharoplasty procedures are 
    performed on an inpatient basis). In light of this and our concern 
    about the cosmetic nature of the procedures, we have decided against 
    adding CPT codes 15820 through 15823 to the ASC list.
        Comment: Commenters proposed the following procedures for the ASC 
    list. All of these procedures involve removal of various size skin 
    lesions from different anatomical locations. They are CPT codes 11400 
    through 11403, 11420 through 11423, 11440 through 11443 (all of which 
    involve excision of benign skin lesions); and CPT codes 11600 through 
    11603, 11620 through 11623, and 11640 through 11643 (all of which 
    involve excision of malignant skin lesions).
        Response: A review of our billing data indicates that all these 
    procedures are performed in the physician's office from 70 percent to 
    91 percent of the time, with most of the procedures performed 80 
    percent of the time in the physician's office setting. They are 
    therefore appropriate to the physician's office and not the ASC.
        Comment: One commenter proposed the following codes for addition to 
    the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    19200.  Mastectomy, radical, including pectoral muscles, axillary lymph 
             nodes.                                                         
    19220.  Mastectomy, radical, including pectoral muscles, axillary and   
             internal mammary lymph nodes (Urban type operation).           
    ------------------------------------------------------------------------
    
        Response: These procedures involve axillary node dissection. After 
    consultation with physicians in the community, our medical staff 
    believe these procedures do not meet the ASC criteria. Surgical time 
    frequently exceeds the 90 minutes specified for ASCs in 
    Sec. 416.65(b)(1)(i). In addition, since these procedures have 
    potential for greater complications, they generally require more 
    observation time than the 4 hours specified for inclusion on the ASC 
    list in Sec. 416.65(b)(1)(ii). We believe these procedures are 
    appropriately performed on an inpatient basis, and our data indicate 
    they are both performed 90 percent of the time in the inpatient 
    setting. Therefore, we are not adding them to the ASC list.
        Comment: Commenters proposed addition of the following codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    19162.  Mastectomy, partial; with axillary lymphadenectomy.             
    19240.  Mastectomy, modified radical, including axillary lymph nodes,   
             with or without pectoralis minor muscle, but excluding         
             pectoralis major muscle.                                       
    ------------------------------------------------------------------------
    
        Response: Our billing data indicate that CPT code 19162 is 
    performed on an inpatient hospital basis 78 percent of the time, and 
    CPT code 19240 is performed on an inpatient hospital basis 92 percent 
    of the time. In addition, CPT code 19162 requires longer than the 4-
    hour recovery time requirement, and CPT code 19240 requires longer than 
    the 90-minute operating time requirement for ASC coverage set forth at 
    Sec. 416.65(b)(1)(i). Therefore, they fail to meet our criteria for 
    coverage in an ASC.
    
    Musculoskeletal System
    
        Comment: One commenter suggested the addition of the following 
    codes to the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    22110.  Partial excision of vertebrae (eg, for osteomyelitis); cervical.
    22114.  Partial excision of vertebrae (eg, for osteomyelitis); lumbar.  
    ------------------------------------------------------------------------
    
        Response: CPT code 22110 is performed 80 percent of the time on an 
    inpatient basis; and CPT code 22114, 94 percent. CPT codes 22110 and 
    22114 are not appropriate for the ASC setting because the procedures 
    require extensive dissection and a recovery time of more than 4 hours.
        Comment: One commenter proposed CPT code 29848 (arthroscopy, wrist 
    with release of transverse carpal ligament) for addition to the ASC 
    list.
        Response: CPT code 29848 is performed 8 percent of the time on an 
    inpatient basis and does not meet our 20 percent inpatient criterion.
    
    Respiratory System
    
        Comment: One commenter proposed the addition of the following codes 
    to the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    31231.  Nasal endoscopy, diagnostic, unilateral or bilateral (separate  
             procedure).                                                    
    31233.  Nasal/sinus endoscopy, diagnostic with maxillary sinusoscopy    
             (via inferior meatus or canine fossa puncture).                
    31235.  Nasal/sinus endoscopy, diagnostic with sphenoid sinusoscopy (via
             puncture of sphenoidal face or cannulation of osteum).         
    ------------------------------------------------------------------------
    
        Response: CPT codes 31233 and 31235 were replacement codes to codes 
    previously on the ASC list. They were cross-referred from existing 
    codes in the 1994 CPT, and both have been added to the list by our 
    manual instructions. (These procedures are listed in Addendum C, part 
    6, at the end of this notice.) We are not adding CPT code 31231 to our 
    list because it replaced [[Page 5191]] CPT code 31250. This procedure 
    was performed 90 percent of the time in the physician's office setting, 
    thus failing to meet our criterion for inclusion on the ASC list.
    
    Digestive System
    
        Comment: Two commenters proposed the following codes for addition 
    to the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    43030.  Cricopharyngeal myotomy.                                        
    43830.  Gastrostomy, temporary (tube, rubber or plastic) (separate      
             procedure).                                                    
    ------------------------------------------------------------------------
    
        Response: CPT code 43030 is performed 79 percent of the time on an 
    inpatient basis, and CPT 43830 is performed 90 percent of the time on 
    an inpatient basis. There is concern about complications with these 
    procedures, and both also require a 23-hour observation period before 
    discharge. They are therefore not appropriate to the ASC list.
        Comment: Commenters proposed adding the following 19 
    gastrointestinal endoscopy codes that were new CPT codes January 1, 
    1994: CPT codes 43205, 43216, 43244, 43248, 43250, 43259, 43261, 43458, 
    44365, 44376, 44377, 44378, 44394, 44500, 45308, 45309, 45338, 45339, 
    and 45384. Some of the codes involved editorial changes of existing CPT 
    procedures, and some were new CPT procedures.
        Response: We have added 12 of these 19 gastrointestinal codes to 
    the ASC list by our manual instructions. They are CPT codes 43216, 
    43248, 43250, 43261, 43458, 43465, 44394, 45308, 45309, 45338, 45339, 
    and 45384. These 12 CPT codes with their descriptions are listed in 
    Addendum C, part 6, at the end of this notice. We were able to cross-
    refer CPT codes deleted from our ASC list (which were identified in 
    Appendix B of the 1994 CPT, a summary of additions, deletions, and 
    revisions applicable to CPT 1994 codes) to these 12 codes. These codes 
    were replacement codes to codes previously on the ASC list. They were 
    cross-referred from existing codes in the 1994 CPT and have been added 
    to the list by our manual instructions.
        With this notice, we are also adding from Appendix B of the CPT 
    another code that meets our criteria, CPT code 43259 (Upper 
    gastrointestinal endoscopy including esophagus, stomach, and either the 
    duodenum and/or jejunum as appropriate; with endoscopic ultrasound 
    examination). We are not, however, adding CPT codes 43205 
    (Esophagoscopy, rigid or flexible; with band ligation of esophageal 
    varices) and 43244 (Upper gastrointestinal endoscopy including 
    esophagus, stomach, and either the duodenum and/or jejunum as 
    appropriate; with band ligation of esophageal and/or gastric varices) 
    because the treatment of varices risks complications of severe, sudden 
    bleeding, which may require an immediate blood transfusion or the 
    introduction of a special tube to control the bleeding. These remedies 
    would not necessarily be available as quickly in the ASC setting. If 
    complications develop, the patient might require air evacuation to the 
    hospital setting. Also, the medical community does not fully accept the 
    use of band ligation in the treatment of varices because its success 
    and comparison to the standard treatment is yet to be completed.
        We are not adding the following CPT codes to the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    44376.  Small intestinal endoscopy, enteroscopy beyond second portion of
             duodenum, including ileum; diagnostic, with or without         
             collection of specimen(s) by brushing or washing (separate     
             procedure).                                                    
    44378.  Small intestinal endoscopy, enteroscopy beyond second portion of
             duodenum, including ileum; with control of bleeding, any       
             method.                                                        
    44500.  Introduction of long gastrointestinal tube (eg, Miller-Abbott)  
             (separate procedure).                                          
    ------------------------------------------------------------------------
    
        These procedures require that an endoscopy tube be passed through 
    the gastrointestinal system while the patient waits 4 to 6 hours before 
    the physician performs the endoscopic study. The patient would need to 
    be in the ASC from 6 to 10 hours. We believe that this extended time 
    period for the procedure exceeds the spirit, if not the letter, of the 
    regulations set forth at Sec. 416.65(b), which establish 5 1/2 hours as 
    a maximum procedure/recovery time. In conclusion, our medical 
    consultants have determined that CPT codes 43205, 53244, 44376, 44378, 
    and 44500 are not appropriate for Medicare patients in the ASC setting.
        Comment: Commenters proposed adding CPT code 45330 (flexible 
    sigmoidoscopy) to the ASC list.
        Response: This procedure is performed 73 percent of the time in the 
    physician's office and is appropriate to that setting. Therefore, it 
    does not meet the criteria for the ASC list and will not be added.
    
    Urinary System
    
        Comment: One commenter recommended CPT code 51040 (cystostomy tube 
    replacement) for addition to the ASC list.
        Response: This procedure meets our criteria and will be added to 
    the ASC list (see Addendum B).
        Comment: One commenter proposed CPT code 51715 (injection of 
    implant material into the urethra) for addition to the ASC list.
        Response: CPT code 51715 is a new CPT code effective January 1, 
    1994. This procedure was previously coded as ``unlisted'' and was not 
    covered under any other procedure on the ASC list. Our medical staff 
    are knowledgeable of this procedure, and we therefore do not require a 
    year of billing data to make a determination. Our medical staff advise 
    us that this is a physicians' office procedure, and it is not 
    appropriate to add it to the ASC list.
        Comment: One commenter suggested CPT code 51845 (abdomino-vaginal 
    vesical neck suspension) for addition to the ASC list.
        Response: CPT code 51845 is performed on an inpatient basis 92 
    percent of the time. Generally, there is also a 23-hour observation 
    period before discharge. Thus, it exceeds our criterion for the 4-hour 
    recovery time in Sec. 416.65(b)(1)(ii). We are, therefore, not adding 
    it to the ASC list.
        Comment: Commenters proposed CPT code 52450 (transurethral incision 
    of prostate) for addition to the ASC list.
        Response: CPT code 52450 is performed 1 percent of the time in a 
    physician's office and 70 percent of the time on an inpatient basis. It 
    thus meets our criteria and will be added to the ASC list.
        Comment: Commenters proposed the addition to the ASC list of CPT 
    code 52601 (transurethral resection of the prostate (TURP)) when a 
    laser is used.
        Response: CPT code 52601 does not specify use of a laser in its 
    coding description. Thus, the code represents TURPs done by all 
    methods, and it is not possible to identify those performed by laser. 
    CPT code 52601 is commonly performed on an inpatient basis with a 94 
    percent inpatient hospital site of service. Most cases require over 4 
    hours recovery time, and, thus, the procedure does not meet our 
    criteria for coverage in an ASC in Sec. 416.65(b)(1)(ii). Should the 
    CPT develop a new laser TURP code, we would consider this procedure's 
    appropriateness in the ASC.
    
    Male Genital System
    
        Comment: One commenter suggested the addition of radioactive seed 
    implantation to treat prostate cancer.
        Response: There is presently no single surgical procedure code in 
    the CPT describing this procedure and [[Page 5192]] consequently no 
    billing data to determine site of service. We are uncertain which code 
    or codes the commenter is using when performing this procedure, but we 
    understand the procedure is often used in conjunction with a radiology 
    code. Radiology codes cannot be included in our ASC list because the 
    ASC list is restricted to surgical codes in the surgery section of the 
    CPT.
        Comment: Commenters proposed the addition of the following codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    54400.  Insertion of penile prosthesis; non-inflatable (semi-rigid).    
    54401.  Insertion of penile prosthesis; inflatable (self-contained).    
    54405.  Insertion of inflatable (multi-component) penile prosthesis,    
             including placement of pump, cylinders, and/or reservoir.      
    54407.  Removal, repair, or replacement of inflatable (multi-component) 
             penile prosthesis, including pump and/or reservoir and/or      
             cylinders.                                                     
    ------------------------------------------------------------------------
    
        Response: When we previously solicited public comment on penile 
    prostheses implant procedures, we received comments unanimously opposed 
    to the addition of these codes to the list. Commenters indicated that 
    these procedures were inappropriate for the Medicare population in the 
    ASC setting. The procedure recovery time exceeds the 4-hour limit, the 
    maximum allowed for coverage in an ASC. Surgeons performing these 
    procedures reported a recovery time of 24 to 72 hours.
        We have given careful consideration to adding these procedures, 
    based on the new comments we received favoring their addition. One 
    commenter, who previously had written in strong opposition, stated that 
    penile prostheses implants should be added to the list since some 
    patients recover in less than 24 hours. Since our regulations indicate 
    a 4-hour recovery limit, we have determined that these procedures 
    remain inappropriate for the Medicare population in an ASC and should 
    not be added to the list.
    
    Laparoscopy/Peritoneoscopy/Hysteroscopy
    
        Comment: One commenter proposed the following codes for addition to 
    the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    56308.  Laparoscopy, surgical; with vaginal hysterectomy with or without
             removal of tube(s), with or without removal of ovary(s)        
             (laparoscopic assisted vaginal hysterectomy).                  
    56309.  Laparoscopy, surgical; with removal of leiomyomata subserosal   
             (single or multiple).                                          
    ------------------------------------------------------------------------
    
        Response: CPT code 56308 is performed on an inpatient basis 91 
    percent of the time. This procedures involves cutting a hole in the 
    pelvis floor and the severing of major arteries and veins. It also 
    requires longer than 4 hours recovery time. We are therefore not adding 
    it to the ASC list. CPT code 56309 meets our criteria and will be added 
    to the list (see Addendum B).
        Comment: Commenters wrote proposing that the following laparoscopic 
    cholecystectomy procedure codes be added to the ASC list (21 commenters 
    for CPT code 56340, 18 for CPT code 56341, and 17 for CPT code 56342, 
    respectively):
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    56340.  Laparoscopy, surgical; cholecystectomy (any method).            
    56341.  Laparoscopy, surgical; cholecystectomy with cholangiography.    
    56342.  Laparoscopy, surgical; cholecystectomy with exploration of      
             common duct.                                                   
    ------------------------------------------------------------------------
    
        Response: The medical information available indicates laparoscopic 
    cholecystectomy usually requires a 23-hour observation period or an 
    inpatient stay, and, therefore, exceeds the 4-hour recovery time 
    requirement in Sec. 416.65(b)(1)(ii). Therefore, we are not adding it 
    to the list.
        Comment: Commenters also proposed the addition of the following 
    codes to the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    56316.  Laparoscopy, surgical; repair of initial inguinal hernia.       
    56317.  Laparoscopy, surgical; repair of recurrent inguinal hernia.     
    ------------------------------------------------------------------------
    
        Response: These procedures meet our criteria and will be added to 
    the list (see Addendum B).
        Comment: One commenter proposed the following codes for addition to 
    the ASC list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    56351.  Hysteroscopy, surgical; with sampling (biopsy) of endometrium   
             and/or polypectomy, with or without D & C.                     
    56356.  Hysteroscopy, surgical; with endometrial ablation (any method). 
    ------------------------------------------------------------------------
    
        Response: These procedures meet our criteria and will be added to 
    the list (see Addendum B).
    
    Nervous System
    
        Comment: Commenters proposed that we add to the ASC list the 
    following nerve injection codes: CPT codes 62298, 64400, 64402, 64405, 
    64408, 64412, 64413, 64418, 64425, 64435, 64440, 64441, 64445, 64450, 
    64505, and 64508.
        Response: According to our claims data, most of these procedures 
    are performed less than 20 percent of the time on an inpatient basis 
    and over 50 percent of the time in a physician's office (most being 
    performed over 70 percent of the time in a physician's office). The 
    exceptions are CPT codes 62298 and 64425, which meet the physician's 
    office criterion but are performed less than 20 percent of the time in 
    the inpatient setting, and CPT code 64508, which meets the inpatient 
    criterion but is performed over 50 percent of the time in a physician's 
    office. Since all these nerve injection codes fail to meet at least one 
    of the criteria for addition, we are not adding them to the ASC list.
        Comment: One commenter proposed the addition of CPT code 64421 
    (injection of intercostal nerves).
        Response: CPT code 64421 is performed 31 percent of the time in a 
    physician's office and 22 percent of the time on an inpatient basis. 
    This procedure thus meets our criteria and will be added to the list 
    (see Addendum B).
        Comment: Two commenters proposed the addition to the ASC list of 
    CPT code 64612, and one commenter proposed CPT code 64613. The 
    descriptions of these CPT codes follow:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    64612.  Destruction by neurolytic agent (chemodenervation of muscle     
             endplate); muscles enervated by facial nerve (eg, for          
             blepharospasm, hemifacial spasm).                              
    64613.  Destruction by neurolytic agent (chemodenervation of muscle     
             endplate); cervical spinal muscles (eg, for spasmodic          
             torticollis).                                                  
    ------------------------------------------------------------------------
    
        Response: CPT code 64612 is performed in the physician's office 84 
    percent of the time, and CPT code 64613 [[Page 5193]] is performed in 
    the physician's office 74 percent of the time. Thus, the codes fail to 
    meet the criteria for our list.
    
    Eye and Ocular Adnexa
    
        Comment: One commenter proposed the addition of CPT code 65770 
    (keratoprosthesis).
        Response: CPT code 65770 is performed 10 percent of the time in a 
    physician's office and 62 percent of the time on an inpatient basis. 
    This procedure thus meets our criteria and will be added to the list 
    (see Addendum B).
        Comment: Several commenters suggested adding CPT code 65772 
    (corneal relaxing incision for correction of surgically induced 
    astigmatism), and one suggested adding code CPT code 65775 (corneal 
    wedge resection for correction of surgically induced astigmatism).
        Response: Neither procedure meets our inpatient criterion. CPT 
    codes 65772 is performed 1 percent of the time on an inpatient basis, 
    and CPT code 65775 is performed 3 percent of the time on an inpatient 
    basis. Therefore, we are not adding them to the ASC list.
        Comment: Commenters proposed the addition of the following CPT 
    codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    65855.  Trabeculoplasty by laser surgery, one or more sessions (defined 
             treatment series).                                             
    66761.  Iridotomy/iridectomy by laser surgery (eg, for glaucoma) (one or
             more sessions).                                                
    67145.  Chemodenervation of extraocular muscle.                         
    67210.  Destruction of localized lesion of retina (eg, maculopathy,     
             choroidopathy, small tumors), one or more sessions;            
             photocoagulation (laser or xenon arc).                         
    67228.  Destruction of extensive or progressive retinopathy (eg,        
             diabetic retinopathy), one or more sessions; photocoagulation  
             (laser or xenon arc).                                          
    ------------------------------------------------------------------------
    
        Commenters stated that these codes are already performed from 25 
    percent to 40 percent of the time in the OPD, and their failure to meet 
    the 20 percent inpatient criterion should not preclude their addition 
    to the ASC list.
        Response: A review of our most recent billing data indicates that 
    none of these procedures is performed 40 percent of the time in the 
    OPD; rather, they are performed from 14 percent to 30 percent of the 
    time in the OPD. However, each of these procedures is performed from 58 
    percent to 79 percent of the time in a physician's office. Since these 
    procedures not only fail to meet the 20 percent inpatient criterion but 
    also the 50 percent physician's office criterion, they will not be 
    added to the ASC list.
        Comment: One commenter proposed the following CPT codes for 
    addition to the list:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    65125.  Modification of ocular implant (eg, drilling receptacle for     
             prosthesis appendage) (separate procedure).                    
    65860.  Severing adhesions of anterior segment, laser technique         
             (separate procedure).                                          
    66172.  Fistulization of sclera for glaucoma; trabeculectomy ab externo 
             with scarring from previous ocular surgery or trauma (includes 
             injection of antifibrotic agents).                             
    66825.  Repositioning of intraocular lens prosthesis, requiring an      
             incision (separate procedure).                                 
    ------------------------------------------------------------------------
    
        Response: CPT codes 65125 and 66825 do not meet the inpatient 
    criterion. CPT code 65125 is performed 5 percent of the time on an 
    inpatient basis, and CPT code 66825 is performed 7 percent of the time 
    on an inpatient basis. CPT code 65860 is performed in a physician's 
    office 65 percent of the time. CPT code 66172 is a new code added in 
    1994 and is not cross-referred to a procedure currently covered in an 
    ASC. We generally need a year of billing data before we can make a 
    decision as to the appropriate setting for performance. Therefore, none 
    of these codes will be added to the ASC list.
        Comment: One commenter proposed the addition of CPT code 66820 
    (discission of secondary membraneous cataract, stab incision).
        Response: CPT code 66820 is performed 5 percent of the time on an 
    inpatient basis and 53 percent of the time in a physician's office and, 
    thus, fails to meet our criteria and will not be added to the list.
        Comment: Commenters proposed the addition of the following codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    67345.  Chemodenervation of extraocular muscle.                         
    67900.  Repair of brow ptosis (supraciliary, mid-forehead or coronal    
             approach).                                                     
    68115.  Excision of lesion, conjunctiva; over 1 cm.                     
    ------------------------------------------------------------------------
    
        Response: CPT code 67345 is a physician's office procedure, 
    performed 85 percent of the time in that setting. CPT codes 67900 and 
    68115 fail to meet our inpatient criterion with only 3 percent each 
    inpatient performance. Therefore, these codes will not be added to the 
    ASC list.
    
    Auditory System
    
        Comment: Commenters proposed the addition of CPT code 69433 
    (tympanostomy).
        Response: This procedure is performed 91 percent of the time in a 
    physician's office. Therefore, it fails to meet the criteria for 
    inclusion on the ASC list.
    
    Other Procedures
    
        Comment: One commenter proposed the use of hyperbaric medical 
    treatment in an ASC with payment for an appropriate technical 
    component. The commenter stated that the routine care of wounds in 
    conjunction with the use of hyperbaric treatments is included under CPT 
    code 99183, but this code does not include coverage of technical costs 
    in an ASC.
        Response: The Medicare list of surgical procedures covered in an 
    ASC includes only surgical procedures listed in the surgical section of 
    the CPT. Hyperbaric medical treatment is not surgery and is listed in 
    the CPT under miscellaneous, special services. Thus, we cannot add it 
    to the ASC list.
    
    Proposed Deletions
    
    Integumentary System
    
        Comment: We proposed to delete nine skin lesion excision codes: CPT 
    codes 11042, 11424, 11604, 13101, 13121, 13132, 13152, 14040, and 
    14041. All nine codes received comments opposing their deletion. 
    Commenters stated that these procedures may sometimes involve 
    complications and compromise safety in the physician's office.
        Response: The physician's office site of performance for these 
    procedures ranges from 53 percent to 71 percent. However, each of these 
    CPT procedure codes involves a range of lesion sizes and anatomical 
    sites. For example, CPT code 11424, representing a 3.1 to 4.0 cm. 
    lesion, includes scalp, neck, hands, feet, and genitalia. While a 4 cm. 
    foot or hand lesion may be excised in the physician's office, a 4 cm. 
    lesion on the genitalia requires a higher surgical setting. Larger size 
    lesions, especially if malignant, require the sterile environment of an 
    operating room, extensive anesthesia, and the monitoring of patient 
    cardiovascular parameters and vital signs. Our medical staff thus 
    believe the commenters are correct that our site-of-service data for 
    these codes are deceptive.
        As we have stated earlier in this notice and in previous notices, 
    we may occasionally make an exception to our general criteria, if, 
    based on the advice of our medical staff, we believe that the site-of-
    service data are deceptive. We [[Page 5194]] are making an exception to 
    the criteria and retaining all the referenced skin lesion codes, based 
    on the recommendation of our medical staff and consultants.
    
    Cardiovascular System
    
        Comment: Commenters opposed the deletion of the following codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    36530.  Insertion of implantable intravenous infusion pump.             
    36531.  Revision of implantable intravenous infusion pump.              
    36532.  Removal of implantable intravenous infusion pump.               
    ------------------------------------------------------------------------
    
        Response: We stated in the proposed notice that the Office of 
    Health Technology Assessment (OHTA), a component of the Public Health 
    Service's Agency for Health Care Policy and Research, would be issuing 
    an assessment on the safety and efficacy of infusion pumps for certain 
    treatments and we would re-evaluate our policy on these pumps in light 
    of that assessment. OHTA issued its assessment, and consequently we 
    revised our manual instruction in section 60-14B of the Medicare 
    Coverage Issues Manual. According to this revision, the former 
    instruction limiting Medicare coverage of infusion pumps to intra-
    arterial pumps for certain medical conditions has been revised to 
    include intravenous infusion pumps for a greater number of medical 
    indications. As a result, we are not deleting CPT codes 36530, 36531, 
    and 36532.
        Comment: Several commenters were opposed to our deletion of CPT 
    code 63750 (insertion, subarachnoid catheter with reservoir and/or pump 
    for intermittent or continuous infusion of drug, including laminectomy) 
    and CPT code 63780 (insertion or replacement, subarachnoid or epidural 
    catheter, with reservoir and/or pump for drug infusion, without 
    laminectomy).
        Response: Our medical advisors state that these procedures can be 
    performed safely, effectively, and appropriately in the ASC setting. We 
    are therefore retaining these procedures on the list.
    Urinary System
        Comment: We received over 300 comments in opposition to the 
    deletion of CPT code 52000 (cystourethroscopy (separate procedure)). Of 
    these comments, 200 were also against deleting the following CPT codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    52281.  Cystourethroscopy, with calibration and/or dilation of urethral 
             stricture or stenosis, with or without meatotomy and injection 
             procedure for cystography, male or female.                     
    52285.  Cystourethroscopy for treatment of the female urethral syndrome 
             with any or all of the following: urethral meatotomy, urethral 
             dilation, internal urethrotomy, lysis of urethrovaginal septal 
             fibrosis, lateral incision of the bladder neck, and fulguration
             of polyp(s) of urethra, bladder neck, and/or trigone.          
    ------------------------------------------------------------------------
    
        Most commenters opposed to the cystoscopy's deletion were 
    urologists. The main themes mentioned by the commenters were the 
    following: the differences in male and female cystoscopies, the 
    differences in type of cystoscopies, diagnostic versus therapeutic 
    cystoscopies, our deceptive data, and physician/patient access 
    problems.
        Response: Although the three cystoscopies proposed for deletion 
    exceed our physician's office criterion, we are making an exception to 
    this standard and retaining these codes on the list, based on the 
    advice of our medical staff and consultants. Numerous commenters 
    offered significant medical evidence for retention of cystoscopies on 
    the ASC list, especially for male patients. Moreover, an exhaustive 
    review of our data supports the commenters' belief that female 
    cystoscopies skew the data in favor of the physician's office site of 
    service and many CPT code 52000 cystoscopies, when performed, are 
    upgraded to therapeutic cystoscopies and not reported under CPT code 
    52000.
    Male Genital System
        Comment: We received 136 comments in opposition to the deletion of 
    CPT code 55700 (prostate biopsy). The following were the main themes 
    mentioned in the comments: patient health, complications and infection, 
    sterilization problems, and the use of the ultrasound machine.
        Response: As with cystoscopies, information indicates many patients 
    in need of a prostate biopsy have comorbidities or other complications 
    that necessitate close monitoring. Complications of prostate biopsy can 
    be serious. Infection and bleeding are not uncommon and, at times, 
    warrant hospital admission.
        Although prostate biopsy exceeds our physician's office criterion, 
    we are making an exception to our standard and are retaining this 
    procedure on the list. We base our determination on the number of 
    comments received citing significant medical evidence, and the advice 
    of our medical staff and consultants that prostate biopsy is an 
    appropriate procedure for the ASC list.
    Nervous System
        Comment: Several commenters were opposed to our proposed deletion 
    of the following codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    64442.  Injection, anesthetic agent; paravertebral facet joint nerve,   
             lumbar, single level.                                          
    64510.  Injection, anesthetic agent; stellate ganglion (cervical        
             sympathetic).                                                  
    ------------------------------------------------------------------------
    
        They believed these codes should not be deleted because they 
    frequently require the standby of a crash cart, should a complication 
    occur during injection. CPT code 64442 requires a fluoroscopy, which 
    few physicians' offices own; CPT code 64510 may compromise the 
    patient's airway with the inadvertent block of a laryngeal nerve with a 
    local anesthetic; and both procedures cause patient cardiac arrhythmias 
    in 25 percent of patients. Commenters believed our data are erroneous 
    since the data exclude anesthesiologists from site-of-service data, and 
    anesthesiologists are the primary physicians performing these 
    procedures.
        Response: In view of these stated medical concerns and because the 
    inclusion of anesthesiologists in a new claims data run resulted in the 
    two procedures falling below the 50 percent physician's office 
    criterion, both procedures will be retained on the list.
    
    Eye and Ocular Adnexa
    
        Comment: We received comments in opposition to our proposed 
    deletion of the following ophthalmologic procedures codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    66762.  Iridoplasty by photocoagulation (one or more sessions) (eg, for 
             improvement of vision, for widening of anterior chamber angle).
    67101.  Repair of retinal detachment, one or more sessions; cryotherapy 
             or diathermy, with or without drainage of subretinal fluid.    
    67105.  Repair of retinal detachment, photocoagulation (laser or xenon  
             arc, one or more sessions), with or without drainage of        
             subretinal fluid.                                              
    [[Page 5195]]                                                           
                                                                            
    67208.  Destruction of localized lesion of retina (eg, maculopathy,     
             choroidopathy, small tumors), one or more sessions;            
             cryotherapy, diathermy.                                        
    67921.  Entropion repair; suture.                                       
    ------------------------------------------------------------------------
    
        Commenters were concerned that these procedures could not be 
    performed in a physician's office without the purchase of costly 
    equipment and they would now have to be performed in the more expensive 
    OPD setting.
        Response: The billing data on site-of-service performance for four 
    of these five procedures (excluding CPT code 67921) range from 53 
    percent to 63 percent physicians' office performance. When considering 
    the combined ASC, OPD, and inpatient hospital performances, these four 
    procedures do not meet the new 46 percent threshold criterion; rather 
    their combined percentages range from 37 percent to 40 percent. In view 
    of these combined percentages, we believe we are justified in adhering 
    to our proposed intention to delete from the ASC list CPT codes 66762, 
    67101, 67105, and 67208.
        The fifth code, CPT code 67921, has a 45 percent combined 
    percentage performance in the three settings. Yet, our medical staff 
    advise us that this procedure, which involves the inversion of the 
    border of the eyelid against the eyeball, is medically appropriate for 
    performance in the ASC. This code is also one of a series of 
    ophthalmological codes involving blepharoplasties mentioned both in 
    this notice and in the previous ASC final notice published in the 
    Federal Register on December 31, 1991 (56 FR 67666) as making 
    unnecessary our coverage of integumentary system blepharoplasties, 
    which are sometimes cosmetic. In view of these factors, we are making 
    an exception to our criteria and are retaining CPT code 67921.
        Comment: Commenters believed that four of the ophthalmic procedures 
    proposed for removal from the list are subject to the interim practice 
    cost reductions. They are the following CPT codes:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    66762.  Iridoplasty by photocoagulation (one or more sessions) (eg, for 
             improvement of vision, for widening of anterior chamber angle).
    67101.  Repair of retinal detachment, one or more sessions; cryotherapy 
             or diathermy, with or without drainage of subretinal fluid.    
    67105.  Repair of retinal detachment, photocoagulation (laser or xenon  
             arc, one or more sessions), with or without drainage of        
             subretinal fluid.                                              
    67208.  Destruction of localized lesion of retina (eg, maculopathy,     
             choroidopathy, small tumors), one ore more sessions;           
             cryotherapy, diathermy.                                        
    ------------------------------------------------------------------------
    
        The commenters stated that we should not remove any procedures 
    subject to the interim practice cost reductions from the ASC list until 
    the fee schedule for physicians' services accurately reflects practice 
    costs.
        Response: The commenters are correct that four of the five 
    ophthalmic procedures (CPT codes 66762, 67101, 67105, and 67208) 
    proposed for deletion from the ASC list are subject to the practice 
    expense reduction. (CPT code 67921 (repair of entropion) is not subject 
    to the practice expense reduction.)
        OBRA '93 provides for an adjustment to practice expense relative 
    value units (RVUs) for services for which practice expense RVUs exceed 
    128 percent of the work RVUs and that are performed less than 75 
    percent of the time in a physician's office setting. The 1994 practice 
    expense RVUs are reduced by 25 percent of the amount by which the 
    practice expense RVUs exceed the 1994 work RVUs. In 1995 and 1996, the 
    excess, as determined for 1994, will be reduced an additional 25 
    percent each year. Practice expense RVUs will not be reduced to an 
    amount less than 128 percent of the 1994 work RVUs for a service. 
    Services performed more than 75 percent of the time in a physician's 
    office setting are not subject to the reduction.
        Services that are primarily performed in a physician's office 
    setting are subject to a payment limit, called the site-of-service 
    limitation, if they are performed in an inpatient hospital or OPD 
    setting. For these procedures, the practice expense RVUs are reduced by 
    50 percent. The limitation on the practice expense RVUs reflects lower 
    practice costs incurred in the OPD. Procedures on the approved ASC list 
    are automatically excluded from this site-of-service limitation.
        We disagree that it is inappropriate to apply the site-of-service 
    limitation to procedures subject to the practice expense reduction. 
    These are two separate limitations established for different purposes. 
    The practice expense reduction is designed to reduce the basic practice 
    expense that has been determined by the Congress to be excessive; 
    whereas the site-of-service limitation applies to procedures primarily 
    performed in an office setting, when the procedures are performed in an 
    inpatient hospital or OPD setting.
    
    Procedures Intended for Deletion
    
        In Addendum E of our December 1993 proposed notice, we published a 
    list of procedures that we intended for deletion that were either 
    recent additions to the list or had low-volume ASC performance or both. 
    The following procedure codes in that addendum received comments.
        Comment: Two commenters were opposed to the deletion of CPT code 
    64420, and one commenter opposed the deletion of CPT codes 65270 and 
    65272. The descriptions of these CPT codes follow:
    
    ------------------------------------------------------------------------
      CPT                                                                   
     Code                              Description                          
    ------------------------------------------------------------------------
    64420.  Injection, anesthetic agent; intercostal nerve single.          
    65270.  Repair of laceration; conjunctiva, with or without              
             nonperforating laceration sclera, direct closure.              
    65272.  Repair of laceration; conjunctiva, by mobilization and          
             rearrangement, without hospitalization.                        
    ------------------------------------------------------------------------
    
        Response: We are retaining these procedures on our list, but we 
    restate our intention to delete them in our next biennial update should 
    they continue to fail to meet our criteria.
    
    Assignment of Payment Groups
    
        Comment: Three commenters disagreed with the proposed payment group 
    assignment of CPT code 66180 (aqueous shunt to extraocular reservoir, 
    (eg, Molteno, Schocket, Denver-Krupin)) to payment group 4. Two 
    commenters, both physicians, recommended that the procedure be placed 
    in payment group 7 because of the time required to perform the 
    procedure and other factors related to postoperative recovery. One 
    commenter, a professional society, compared the procedure in terms of 
    complexity to a scleral buckling procedure for retinal detachment (CPT 
    code 67107) or the placement of a radioactive implant for an ophthalmic 
    malignancy (CPT 67218), both of which are assigned to payment group 5.
        Response: After consultation with our medical advisor, we concur 
    with the professional society that CPT code 66180 more closely 
    resembles procedures currently in payment group 5 in terms of time and 
    resource consumption than it does those in payment group 4 or in 
    payment group 7. We have therefore assigned this procedure to payment 
    group 5. Payment for the aqueous shunt itself (HCFA 
    [[Page 5196]] Common Procedure Coding System (HCPCS) code L8612) is not 
    a part of the facility fee, but rather is made separately under 
    Medicare Part B.
        Comment: A dozen commenters disagreed with the assignment of CPT 
    code 58990 (hysteroscopy, diagnostic) to payment group 1, recommending 
    that it be placed in payment group 3.
        Response: CPT code 58990 was added as a payment group 1 procedure 
    to the list of Medicare-covered ASC procedures, effective for services 
    furnished beginning on January 30, 1992. CPT code 58990 was replaced by 
    CPT code 56350 (hysteroscopy, diagnostic (separate procedure)) in the 
    1993 CPT, and CPT code 58990 was deleted from both the CPT and the ASC 
    list. Because this change constituted essentially an editorial rather 
    than a substantive revision, we retained CPT code 56350 in payment 
    group 1, the same payment group to which its predecessor, CPT code 
    58990, had been assigned. CPT code 56350 is on the list of procedures 
    for which we are collecting resource cost data in Part II of the 
    Medicare ASC survey, and its payment group assignment, along with that 
    of all other procedures on the list of Medicare-covered ASC procedures, 
    will be reevaluated within the context of the survey data. In the 
    interim, CPT code 56350 will remain in payment group 1.
    
    Additional Information
    
        We received several dozen comments on payment issues that were not 
    raised in our December 1993 proposed notice. Primarily, commenters 
    recommended placing CPT codes that are currently on the ASC list in a 
    higher payment group. A few commenters expressed disappointment over 
    the lack of a payment rate update for inflation as a result of the 2-
    year freeze enacted by the Congress in OBRA '93.
        As indicated in our December 1993 proposed notice, we are deferring 
    changes of payment group assignments for individual procedures on the 
    current ASC list pending completion of Part II of the Medicare ASC 
    payment rate survey (Form HCFA 452B). On March 15, 1994, we mailed the 
    Medicare ASC survey, Part II, to 320 facilities that constitute a 
    randomly selected, representative sample of Medicare-participating 
    ASCs. The survey collects data on facility overhead and procedure-
    specific costs. The payment group assignment and payment group amounts 
    for all CPT codes on the list of Medicare-covered ASC procedures will 
    be reviewed collectively, within the context of the survey data. 
    Therefore, while we are not making any changes in existing payment 
    group assignments in this notice, we will publish in the Federal 
    Register in accordance with notice and comment procedures any changes 
    that we propose to make on the basis of updated cost data collected in 
    the ASC survey.
    
    IV. Provisions of the Final Notice
    
        We are adopting the following new quantitative criteria, suggested 
    in our December 1993 proposed notice, for deleting a procedure from ASC 
    coverage: The combined inpatient, OPD, and ASC site-of-service 
    percentage is less than 46 percent of the total volume; and either--
         The procedure is performed 50 percent of the time or more 
    in a physician's office; or
         The procedure is performed 10 percent of the time or less 
    in an inpatient hospital setting.
        This change allows the site of service for procedures in the 
    physician's office to grow from below 50 percent (when it is added) to 
    as high as 54 percent, as long as the proportion of time the procedure 
    is performed in the operating room remains at 46 percent. Similarly, 
    the criteria allow procedures to move from an inpatient hospital site 
    of service to an OPD site of service without being deleted from the ASC 
    list.
        We are deleting 4 of the 25 procedure codes we had proposed for 
    deletion from the ASC list in our December 1993 proposed notice. For 
    the reasons discussed in the analysis of the public comments in section 
    III. of this notice, we are retaining the remaining 21 codes on the ASC 
    list. Addendum A lists the 4 CPT codes that we are deleting (with the 
    body system and description of each procedure, according to appropriate 
    CPT terminology). Addendum A also lists a fifth deletion, CPT code 
    36522 (photopheresis, extracorporeal), which was not suggested in our 
    December 1993 proposed notice. We are deleting this code based on 
    information from a provider that this procedure cannot be safely 
    performed in an ASC. Our review of the billing data indicates that, 
    although this procedure has been on the ASC list, it is performed 0 
    percent of the time in an ASC. It is performed 73 percent of the time 
    on an inpatient basis and 23 percent of the time in the OPD. We are 
    requesting public comment on the appropriateness of this deletion.
        We are adding a total of 30 new procedure codes to the ASC list. 
    These codes are listed in Addendum B with the body system and 
    description of each procedure and the corresponding payment group. We 
    are adding the 20 procedure codes that we had proposed for addition to 
    the ASC list in our December 1993 proposed notice. For the reasons 
    discussed in the analysis of the public comments in section III. of 
    this notice, we are also adding 10 other procedure codes: CPT codes 
    29804, 43259, 51040, 52450, 56309, 56316, 56317, 56351, 56356, and 
    64421. We are requesting public comment on the appropriateness of the 
    addition of these 10 new CPT codes and the assignment of payment groups 
    for them since these codes were not suggested in our December 1993 
    proposed notice.
        Further, the CPT is updated annually and some deletions and 
    additions affect the ASC list. Parts 1 and 3 of Addendum C list CPT 
    codes (with the body system and description of each procedure) that 
    were deleted by changes to the Medicare Carriers Manual as a result of 
    the update of the 1992 and 1993 editions of the CPT, respectively. We 
    had proposed these deletions in our December 1993 proposed notice and 
    received no comments on them. This notice makes these deletions final. 
    Parts 2 and 4 of Addendum C list CPT codes (with the body system and 
    description of each procedure and corresponding payment group) that 
    were added by changes to the Medicare Carriers Manual as a result of 
    the update of the 1992 and 1993 editions of the CPT. We had proposed 
    these additions in our December 1993 proposed notice and received no 
    comments on them. This notice makes these additions final. Part 5 of 
    Addendum C lists CPT codes (with the body system and description of 
    each procedure) that were deleted by changes to the Medicare Carriers 
    Manual as a result of the update of the 1994 edition of the CPT. 
    Because these codes were not suggested for deletion in our December 
    1993 proposed notice, we are now requesting public comment on the 
    appropriateness of these deletions. This list of deletions differs from 
    the Medicare Carriers Manual instruction that was effective April 11, 
    1994, in that we are retaining four of the nasal and sinus endoscopy 
    codes: CPT codes 31254 through 31256 and 31267. We are retaining these 
    codes since we anticipate that they will be reinstated by the CPT 
    Editorial Panel effective January 1995. Part 6 of Addendum C lists CPT 
    codes (with the body system and description of each procedure and 
    corresponding payment group) that were added by changes to the Medicare 
    Carriers Manual as a result of the update of the 1994 edition of the 
    CPT. Because these codes were not suggested for addition in our 
    December 1993 proposed notice, we are now requesting public comment on 
    the appropriateness [[Page 5197]] of, and assignment of payment groups 
    for, the additions.
    
    V. Collection of Information Requirements
    
        This document does not impose information collection and 
    recordkeeping requirements. Consequently, it need not be reviewed by 
    the Office of Management and Budget under the authority of the 
    Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.).
    
    VI. Regulatory Impact Statement
    
    A. Introduction
    
        This final notice permits facility fees to be paid when the 30 
    surgical procedure codes being added by this notice are performed in an 
    ASC. We are also deleting 5 codes from the ASC list. We believe the net 
    effect of the addition and deletion of these codes will be negligible 
    because of the low number of changes we are making at this time and 
    because of the relatively low cost and volume of these codes.
        Payments to ASCs are generally lower than payments to hospitals for 
    surgery performed in a hospital, whether on an inpatient or OPD basis. 
    Although we do not anticipate that many services will shift from the 
    hospital inpatient setting to ASCs, we anticipate some program savings 
    because payments to ASCs for a given surgical procedure are generally 
    lower than payments to hospitals for the same procedure. Additional 
    savings will be realized as a result of lower payments to a hospital 
    when newly listed procedures continue to be performed on an OPD basis, 
    because the OPD rate (less deductible and coinsurance) would be the 
    lower of (1) the hospital's reasonable costs or charges, or (2) a blend 
    of the hospital's reasonable costs or customary charges and the amount 
    that would be paid to a free-standing ASC in the same area for the same 
    procedure. The blend is comprised of 42 percent hospital cost and 58 
    percent ASC payment rate. We believe payments based on the ASC blended 
    rate are approximately 10 percent lower than payments based solely on 
    reasonable cost. A factor that could offset some savings would be a 
    shift of services from the physician's office to the ASC setting as a 
    result of the expansion of the list of covered ASC services. Since a 
    facility fee is not paid when surgery is performed in a physician's 
    office, this shifting will result in slightly increased program costs.
        The deletions to the ASC list could also result in some changes in 
    program costs and savings depending upon whether the deleted services 
    are shifted to the lower cost physician's office site or to the higher 
    cost OPD setting. We do not anticipate mass shifting of the site of 
    service associated with the procedure codes we are adding or deleting.
        We believe this notice will result in no economic impact.
    
    B. Regulatory Flexibility Act
    
        We generally prepare a regulatory flexibility analysis that is 
    consistent with the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 
    through 612) unless the Secretary certifies that a notice will not have 
    a significant economic impact on a substantial number of small 
    entities. For purposes of the RFA, all physicians, ASCs, and hospitals 
    are considered to be small entities.
        In addition, section 1102(b) of the Act requires the Secretary to 
    prepare a regulatory impact analysis if a notice may have a significant 
    impact on the operations of a substantial number of small rural 
    hospitals. This analysis must conform to the provisions of section 604 
    of the RFA. For purposes of section 1102(b) of the Act, we define a 
    small rural hospital as a hospital that is located outside of a 
    Metropolitan Statistical Area and has fewer than 50 beds.
        We will delete a procedure from the ASC list only if the combined 
    hospital inpatient, OPD, and ASC site-of-service percentage is less 
    than 46 percent of the total volume; and either the procedure is 
    performed 50 percent of the time or more in a physician's office, or 
    the procedure is performed 10 percent of the time or less in an 
    inpatient hospital setting. Because procedures will not be added or 
    deleted as a result of slight shifts of the site of service, we believe 
    we are adding stability to the list that should assist all small 
    entities to plan for the future.
        Therefore, for the reasons cited above, we are not preparing 
    analyses for either the RFA or section 1102(b) of the Act since we have 
    determined, and the Secretary certifies, that this notice will not 
    result in a significant economic impact on a substantial number of 
    small entities and will not have a significant impact on the operations 
    of a substantial number of small rural hospitals.
        In accordance with the provisions of Executive Order 12866, this 
    notice was not reviewed by the Office of Management and Budget.

    Addendum A
    
    Deletions From the List of Covered Procedures for Ambulatory 
    Surgical Centers
    
        The following addendum is the final list of deletions from the ASC 
    list. These deletions are effective April 26, 1995. In the first column 
    is the CPT code for the procedure; and in the second column, the body 
    system and description of the procedure. In this addendum, ``combined'' 
    percentage refers to the total of inpatient hospital, hospital 
    outpatient department, and ASC site-of-service percentages.
        We are requesting public comments only on CPT code 36522 in 
    Addendum A because we had not proposed this code for deletion in our 
    December 1993 proposed notice.

    5. Deletions From the List of Covered Procedures for Ambulatory 
    Surgical Centers, Deleted from the 1994 CPT
        The CPT is updated annually, and some additions and deletions 
    affect the ASC list. The following part 5 of this addendum is the list 
    of procedures that were deleted from the ASC list because they were 
    deleted from the 1994 CPT. These deletions were effective April 11, 
    1994. This list of deletions differs from the Medicare Carriers Manual 
    instruction that was effective April 11, 1994, in that we have since 
    decided to retain four of the nasal and sinus endoscopy codes: CPT 
    codes 31254 through 31256 and 31267. We are retaining these codes since 
    we anticipate that they will be reinstated by the CPT Editorial Panel 
    effective January 1995.
        In the first column is the CPT code for the procedure; and in the 
    second column, the body system and description of the procedure.
        We are requesting public comments on the appropriateness of the 
    deletion of the CPT codes in Addendum C, part 5, because we had not 
    suggested them for deletion in our December 1993 proposed notice.

    6. Additions to the List of Covered Procedures for Ambulatory Surgical 
    Centers, Added to the 1994 CPT (Added to the Medicare Carriers Manual 
    January 1, 1994)
        The CPT is updated annually, and some additions and deletions 
    affect the ASC list. The following part 6 of this addendum is the list 
    of procedures that were added to the ASC list because of additions to 
    the 1994 CPT. These procedures were added to the ASC list by the 
    Medicare Carriers Manual and were effective January 1, 1994. In the 
    [[Page 5203]] first column is the CPT code for the procedure; in the 
    second column, the payment group for the procedure; and in the third 
    column, the body system and description of the procedure.
        We are requesting public comments on the appropriateness of the 
    addition of, and assignment of payment groups for, the CPT codes in 
    Addendum C, part 6, because we had not suggested them for addition in 
    our December 1993 proposed notice.
