SUPPLEMENTARY INFORMATION:

VA published a proposed rulemaking in the Federal Register at 80 FR 44913 on July 28, 2015, to amend the portion of the VA Schedule of Rating Disabilities (VASRD or rating schedule) dealing with dental and oral conditions. VA provided a 60-day public comment period and interested persons were invited to submit written comments on or before September 28, 2015. VA received 5 comments.

One commenter suggested further defining the description of mandibular and maxillary malunion and maxillary non-union based on the degree of open bite under diagnostic codes 9904 and 9916. However, the severity of mandibular and maxillary displacement and its effect on anterior or posterior open bite depend on an individual's functional anatomy. Therefore, different veterans with the same degree of displacement would present with different degrees of open bite. A qualified dental provider such as a dentist or oral surgeon would appropriately determine the degree of severity in each individual case. Further, rather than basing the severity of open bite on a range of numerical values, it is standard practice for such dental providers to assess the degree of severity as severe, moderate, mild, or not causing open bite.

Additionally, the commenter suggested defining moderate and severe anterior or posterior open bite and mild anterior or posterior open bite. Similarly, due to the variances between individuals' facial anatomy, it would be improper to use exact numerical values to determine the degree of moderate and severe anterior or posterior open bite and mild anterior or posterior open bite. A qualified dental provider would appropriately measure and record these findings. Therefore, VA makes no changes based on these comments.

The same commenter had a question about why only a 20 percent rating is warranted for severe anterior or posterior open bite due to mandibular malunion and a 30 percent rating is warranted for severe anterior or posterior open bite due to maxillary malunion, while moderate anterior or posterior open bite warrants 10 percent ratings for both conditions. These variations in disability compensation are based on the differences in functional impairment due to maxillary and mandibular fractures. Unlike mandibular fracture and its residuals, maxillary fracture presents a more challenging case for repair and rehabilitation. For example, unlike mandibular fractures, maxillary fractures often communicate with sinuses and/or combine with orbital fractures. Such fractures are predisposed to contamination, sinus infection, and obstruction. Even after following treatment guidelines, significant bony resorption may occur leading to cosmetic contour deformity. Further, although such residuals of maxillary fracture raise the potential for pyramiding, such a situation is addressed by the new note (2) to § 4.150, which directs raters to separately evaluate other impairments under the appropriate diagnostic code. Therefore, the functional impairment due to maxillary fracture significantly differs from mandibular fractures. VA took these functional anatomy differences and the resultant differences in functional impairment into consideration during the revision process.

Additionally, the commenter noted that mandibular malunion and maxillary malunion and non-union do not have the same choices of severity of anterior or posterior open bite. Once more, these differences are based on differences in the functional anatomy of maxillas and mandibles and standard clinical assessments by a qualified dental provider. Therefore, VA makes no changes based on these comments.

Multiple commenters asked for additional guidance in assessing interincisal measurements of maximum unassisted vertical opening under diagnostic code 9905. One commenter stated that guidance was needed on how to handle measurements that fall between the specific numbers. Another commenter suggested adding the phrase “or less” to the whole numbers listed in the proposed rule or using a range of numbers, such as from 21 to 29 millimeters. VA applied a standard scale for the measurement of interincisal ranges, vertical and lateral, based on the Guidelines to the Evaluation of Impairment of the Oral and Maxillofacial Region by the American Association of Oral and Maxillofacial Surgeons. Guidelines to the Evaluation of Impairment of the Oral and Maxillofacial Region, American Association of Oral and Maxillofacial Surgeons can be found at http://www.astmjs.org/​impairment.html. VA agrees that for the sake of clarity, a full range of maximum unassisted vertical opening should be included and makes appropriate edits to diagnostic code 9905.

One commenter stated that VA should address bruxism and its relationship to temporomandibular joint disorder in a note to diagnostic code 9905. Specifically, the commenter stated that VA's treatment of bruxism as only a secondary condition and not a stand alone disability is problematic with regards to claims for dental treatment. The commenter recommended amending 38 CFR 3.381 to clarify the treatment of bruxism in regards to service connection for dental treatment or to add to diagnostic code 9905 the phrase “with or without bruxism.” The commenter also recommended rating bruxism as a stand alone issue. However, bruxism is considered a symptom of craniomandibular disorders, of which temporomandibular disorders are a subset; other symptoms of craniomandibular disorders include anxiety, stress, and other mental disorders (Shetty, Shilpa et al., Bruxism: A Literature Review, J Indian Prosthodont Soc. 2010 Sep; 10(3): 141-148., https://www.ncbi.nlm.nih.gov/​pmc/​articles/​PMC3081266/​). Therefore, it is not appropriate to place bruxism as a separate diagnosis or a symptom under diagnostic code 9905. VA has determined that only secondary service connection for treatment purposes is warranted for this condition, both because it is only a secondary condition, not a primary condition, and because its symptoms are already contemplated by the underlying condition for which the veteran is being compensated. Thus, it does not require a separate diagnostic code, and VA makes no changes based on this comment.

One commenter had a question about why diagnostic codes 9901, 9908, 9909, 9913, 9914, and 9915 were missing from the discussion. VA did not propose any changes to these diagnostic codes. According to the Federal Register Document Drafting Handbook Rule 1.14, this was noted by inserting asterisks in place of unchanged diagnostic codes. Therefore, VA makes no changes based on this comment.

The same commenter proposed to rate maxillary and mandibular malunion and non-union exactly the same way, regardless of which bone is affected. However, the functional impairment due to mandibular malunion and non-union significantly differs from maxillary malunion and non-union. VA took these differences in functional anatomy and the resultant differences in functional impairment into consideration during the revision process. Therefore, VA makes no changes based on this comment.

One commenter was supportive of the overall changes and additions to this section of the rating schedule. However, the commenter stated that a service-connected noncompensable rating for a dental disability inappropriately restricts the ability of a recently discharged veteran whose eligibility for outpatient dental services is based on 38 CFR 17.161(b) [Class II] to receive appropriate dental services and appliances. To illustrate, the commenter stated that the dental rating schedule provides for a diagnosis of “loss of teeth, replaceable by prosthesis” with diagnostic code 9913. Because the schedule considers this to be a noncompenable disability, the veteran is limited to receiving one-time treatment for this condition under 38 CFR 17.161(b). The commenter described why this is not a suitable clinical response for the veteran, especially over the veteran's life-time. Specifically, the commenter stated that the provision of dentures has historically been, and continues to be, VA's treatment response for this condition, even though (1) modern dentistry, as practiced in the community, goes beyond this, offering partial dentures, implants, bridges, crowns, and other prostheses, and (2) the use of dentures may be inappropriate and more harmful to the future dental health of the veteran (e.g., where their use, to address a lost tooth, requires the removal of other healthy teeth to fit them). Moreover, this commenter stated that limiting this veteran to one-time treatment for this condition is outdated and a disservice to the veteran, further noting that, even were these newer treatment options available to this cohort, the one-time limitation would still be unreasonable because these newer options typically require replacement after several years. The commenter believes all of these problems would be remedied by either ensuring that this dental condition (diagnostic code 9913) is changed to reflect a compensable rating for veterans who experience complications of treatment, such as inability to load the prosthesis, diminished vocal projection, chronic pain, or peri-implantitis. In the alternative, this particular dental condition/diagnosis could be excepted from the one-time treatment limitation under § 17.161(b). Lastly, this commenter suggested adding a general note under 38 CFR 4.150 to allow for analogous compensable ratings for any dental disabilities service-connected (or treated as service-connected under 38 U.S.C. 1151) which require ongoing treatment.

Veterans with a service-connected compensable dental condition are eligible for any outpatient dental treatment indicated as reasonably necessary to maintain oral health and masticatory function, with no time limits for making application for treatment and no restrictions as to the number of repeat episodes of treatment under 38 CFR 17.161(a). In addition, other veteran-cohorts are eligible for outpatient dental treatment as specified in § 17.161. Under § 17.161(b) [Class II], a veteran's eligibility for the one-time correction of a service-connected noncompensable dental condition is available to certain veterans who have been recently discharged or released from active service, if specified requirements, including timely filing of the dental application, are met. (No rating action is needed for Class II applicants if the conditions set forth in 38 CFR 17.162 are met).

While we appreciate the arguments raised by the commenter and his advocacy efforts on behalf of the members of his organization, this rulemaking does not seek to revise diagnostic code 9913, as it applies to the loss of teeth, replaceable by prosthesis. As such, these comments go beyond the scope of this rulemaking, which is focused on other codes in the dental rating schedule. Further, a veteran's Class II eligibility for outpatient dental services and applicances is not based on the level of functional impairment for which the Veteran is compensated under 38 CFR part 4. Ratings provided for service-connected conditions under 38 CFR part 4 serve solely to compensate veterans for functional impairment resulting from diseases and injuries and any residuals. In addition, VA has determined that the dental conditions contemplated by § 17.161(b) do not, in general, result in functional impairment. Indeed, VA experts recently carefully considered this very issue as part of an independent undertaking, but they concluded that while such a change would serve a great convenience to affected veterans, no clinical justification exists to change the non-compensable designation given to conditions under diagnostic code 9913, to include loss of teeth, replaceable by prosthesis. Moreover, the commenter's broader suggested amendments to VA's outpatient treatment dental regulations likewise go beyond the scope of this immediate rulemaking, which again is focused on limited components of the dental rating schedule. Finally, we note that the eligibility criteria set forth in § 17.161(b) are based in law, 38 U.S.C. 1712(a)(1)(B), (b), and so cannot be changed via rulemaking. As a result of all these factors, no changes to VA's outpatient dental regulations are made in response to this commenter's comments related to diagnostic code 9913.

The same commenter was supportive of the overall changes and additions to diagnostic codes 9904 and 9916. However, the commenter was concerned about inter-examiner and inter-rater reliability due to the descriptors of open bite, noting that vague descriptors could result in under-evaluation or pyramiding. As discussed above, due to the variances between individuals' facial anatomy, it would be improper to use exact numerical values to determine the degree of moderate and severe anterior or posterior open bite and mild anterior or posterior open bite. Further, the potential for pyramiding is addressed by the new note (2) to § 4.150, which directs raters to separately evaluate other impairments under the appropriate diagnostic code. Additionally, VA took differences in functional anatomy of maxillas and mandibles into consideration during the revision process. Therefore, VA makes no changes based on this comment.

One commenter urged VA to include periodontal disease as a compensable condition and amend 38 CFR 3.381 accordingly. The commenter stated that periodontal disease has been linked to diabetes as well as other conditions, and veterans who have service-connected diabetes as a result of herbicide exposure are not able to receive dental treatment unless their overall disability rating is 100 percent. The commenter stated that assigning a compensable disability rating for periodontal disease or providing for a compensable rating as a secondary disability associated with service-connected diabetes would alleviate the lack of treatment issue for veterans. As noted previously, the ratings under 38 CFR part 4 serve to compensate for functional impairment. VA has determined that periodontal disease does not result in loss of earning capacity resulting from functional impairment, so no changes have been made to make this condition compensable. Therefore, VA makes no changes based on these comments.

VA is correcting typographical errors under DC 9905 and DC 9916. With respect to DC 9905, in the proposed rulemaking notice, for the 50 percent evaluation, VA referred to mechanically altered food instead of mechanically altered foods. With respect to DC 9916, in the explanatory note for disability rating personnel, VA failed to include the phrase “following treatment” between “maxilla fragments” and the parenthetical. VA is correcting these errors in this final rule.

VA appreciates the comments submitted in response to the proposed rulemaking notice. Based on the rationale stated in the proposed rulemaking notice and in this document, the final rule is adopted with the changes noted.

Effective Date of Final Rule

Veterans Benefits Administration (VBA) personnel utilize the Veterans Benefit Management System for Rating (VBMS-R) to process disability compensation claims that involve disability evaluations made under the VASRD. In order to ensure that there is no delay in processing veterans' claims, VA must coordinate the effective date of this final rule with corresponding VBMS-R system updates. As such, this final rule will apply effective September 10, 2017, the date VBMS-R system updates related to this final rule will be complete.

Executive Orders 12866 and 13563

Executive Orders 12866 and 13563 direct agencies to assess the costs and benefits of available regulatory alternatives and, when regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, and other advantages; distributive impacts; and equity). Executive Order 13563 (Improving Regulation and Regulatory Review) emphasizes the importance of quantifying both costs and benefits, reducing costs, harmonizing rules, and promoting flexibility. Executive Order 12866 (Regulatory Planning and Review) defines a “significant regulatory action,” requiring review by the Office of Management and Budget (OMB), unless OMB waives such review, as “any regulatory action that is likely to result in a rule that may: (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities; (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in this Executive Order.”

The economic, interagency, budgetary, legal, and policy implications of this final rule have been examined, and it has been determined not to be a significant regulatory action under Executive Order 12866. VA's impact analysis can be found as a supporting document at http://www.regulations.gov,, usually within 48 hours after the rulemaking document is published. Additionally, a copy of this rulemaking and its impact analysis are available on VA's Web site at http://www.va.gov/​orpm/​,, by following the link for “VA Regulations Published From FY 2004 Through Fiscal Year to Date.”

Regulatory Flexibility Act

The Secretary hereby certifies that this final rule will not have a significant economic impact on a substantial number of small entities as they are defined in the Regulatory Flexibility Act, 5 U.S.C. 601-612. This final rule will not affect any small entities. Only certain VA beneficiaries could be directly affected. Therefore, pursuant to 5 U.S.C. 605(b), this rulemaking is exempt from the initial and final regulatory flexibility analysis requirements of sections 603 and 604.

Unfunded Mandates

The Unfunded Mandates Reform Act of 1995 requires, at 2 U.S.C. 1532, that agencies prepare an assessment of anticipated costs and benefits before issuing any rule that may result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100 million or more (adjusted annually for inflation) in any one year. This final rule will have no such effect on State, local, and tribal governments, or on the private sector.

Paperwork Reduction Act

This final rule contains no provisions constituting a collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3521).
