2017-23044. Schedule for Rating Disabilities; The Endocrine System

AGENCY:

Department of Veterans Affairs.

ACTION:

Final rule.

SUMMARY:

This document amends the Department of Veterans Affairs (VA) Schedule for Rating Disabilities (VASRD) by revising the portion of the Schedule that addresses endocrine conditions and disorders of the endocrine system. The effect of this action is to ensure that the VASRD uses current medical terminology and to provide detailed and updated criteria for evaluation of endocrine disorders.

DATES:

This rule is effective on December 10, 2017.

FOR FURTHER INFORMATION CONTACT:

Ioulia Vvedenskaya, Medical Officer, Part 4 VASRD Regulations Staff (211C), Compensation Service, Veterans Benefits Administration, Department of Veterans Affairs, 810 Vermont Avenue NW., Washington, DC 20420, [e-mail], [phone] (this is not a toll-free telephone number).

SUPPLEMENTARY INFORMATION:

VA published a proposed rule in the Federal Register at 80 FR 39011 on July 8, 2015, to amend the portion of the VASRD dealing with endocrine disorders. VA provided a 60-day public comment period, and interested persons were invited to submit written comments, suggestions, or objections on or before September 8, 2015. VA received comments from four individuals. In addition, VA received a comment from a veterans service organization. Unless otherwise indicated below, VA adopts the changes set forth in the proposed rule.

Public Comments

One commenter asked whether VA would recognize polycystic ovarian syndrome (PCOS) under the VA rating schedule. VA has a mechanism in place to address PCOS under 38 CFR 4.116. Specifically, the rating schedule for Gynecological Conditions and Disorders of the Breast addresses various ovarian conditions under Diagnostic Code (DC) 7615, “Ovary, disease, injury, or adhesions of” and allows VA to rate based on whether symptoms are controlled by or require continuous treatment. In exceptional cases where the schedular evaluation is inadequate, 38 CFR 3.321 allows for extraschedular evaluation. Therefore, VA makes no changes based on this comment.

Two commenters proposed additional modifications to DC 7913, “Diabetes mellitus.” One commenter suggested adding a note to address the issue of regulation of activities. Another commenter suggested not changing the insulin requirements within DC 7913 without considering the other requirements in the DC such as regulation of activities. The same commenter suggested removing the insulin requirement for a 20-percent rating and the regulation of activities requirement at all disability ratings under the DC. The commenter stated that the functional impairment caused by required use of insulin is greater than impairment caused by ingestion of oral medication to control diabetes. As stated in the proposed rule, VA is not proposing any change to the evaluation criteria for DC 7913 at this time other than requiring “one or more daily injection” of insulin for a 20-, 40- or 60-percent rating and instead intends to establish a work group to specifically address this condition. Therefore, these comments are beyond the scope of this rulemaking. However, VA will take these comments into consideration in connection with a possible future rulemaking.

One commenter suggested changing the terminology for a 100-percent rating under DC 7903, “Hypothyroidism” from “myxedema” to “myxedema coma or crisis” because myxedema can be present without causing the requisite level of symptoms for a 100-percent rating. Myxedema is a term used to denote severe hypothyroidism, and myxedema coma or myxedema crisis is a medical emergency and represents a specific rare life-threatening clinical condition. Because the clinical picture of myxedema appears in the most extreme cases of hypothyroidism, we believe that this manifestation of the disability warrants a 100-percent rating (See Greenspan's Basic & Clinical Endocrinology (D.G. Gardner et al. eds., 9th ed. 2011) available at http://accessmedicine.mhmedical.com/​content.aspx?​bookid=​380&​sectionid=​39744047#8401831). Therefore, VA makes no changes based on this comment.

The same commenter proposed that VA retain a 10-percent minimum evaluation in the DCs for endocrine disabilities because of the need for continuous medication to control the symptoms of these disabilities. VA disagrees. In the absence of symptoms, medical management of chronic endocrine disorders does not present a significant lifestyle adjustment, and it does not result in impairment of earning capacity (see 38 U.S.C. 1155). Therefore, VA makes no changes based on this comment.

The same commenter noted a typographical error in the text of proposed DC 7911. The word “adrenocortical” was misspelled as “adrenalcortical.” VA has changed the spelling of the term based on this comment.

One commenter was supportive of the overall changes and additions to this section of the VASRD, such as additional DCs, clarification of notes on residuals affecting other body systems, instructions to rate some residuals separately, accounting for additional symptoms, and formation of a new work group for diabetes mellitus. The commenter also commented that proposed DCs 7900 (Hyperthyroidism), 7903 (Hypothyroidism), and 7905 (Hypoparathyroidism) do not adequately account for disability due to uncontrolled thyroid hormone or calcium imbalance because proposed DCs 7900 and 7903 only provide a 30-percent rating for symptoms existing for up to six months after diagnosis and proposed DC 7905 provides a 100-percent rating for symptoms occurring for up to three months after diagnosis; thereafter, residual effects are rated under the body system affected by the endocrine disability. The commenter stated that endocrine function may still be disturbed while the correct dosage of medication is being determined and that some patients may not have received treatment.

We first point out that the ratings under DC 7900 and 7903 are for “six months after initial diagnosis” and the rating under DC 7905 is for “three months after initial diagnosis.” Thus, the claimants are likely receiving treatment. In addition, as VA explained in the notice of proposed rulemaking, most symptoms of hyperthyroidism and hypothyroidism are alleviated within six months of treatment (see 80 FR 39011, 39013 (Jul. 8, 2015)).

With regard to residual symptoms, the primary effect of chronic hyperthyroidism, hypothyroidism, and hypoparathyroidism is on body systems regulated by the thyroid. Therefore, in cases where veterans still have symptoms after six months for hyperthyroidism or hypothyroidism or after three months for hypoparathyroidism, VA addresses residual symptoms by rating all residuals based on the specific disability presented under the most appropriate DCs within the appropriate body system(s).

The residuals of endocrine disorders such as uncontrolled thyroid hormone or calcium imbalance produce measurable disability including muscle damage, blood-clotting issues, nerve and kidney damage, depression, and many others. Therefore, VA makes no changes based on this comment.

The commenter also stated that VA has not provided a reasoned argument for eliminating a 10-percent evaluation when continued medication is required under DCs 7900 and 7903. Ratings under the schedule are “based, as far as practicable, upon the average impairments of earning capacity resulting from [specific] injuries” or combination of injuries (see 38 U.S.C. 1155). As detailed above, VA explained in the notice of proposed rulemaking that symptoms of hyperthyroidism and hypothyroidism generally resolve completely within six months after diagnosis and that symptoms of hypoparathyroidism are generally eliminated following treatment with calcium and vitamin D supplementation (see 80 FR 39011, 39012-14 (Jul. 8, 2015)). Because symptoms are generally eliminated or minimal once a patient receives appropriate medication, there is no impairment of earning capacity and therefore no need to retain the 10-percent rating under DCs 7900, 7903, and 7905. As explained above, any disabling residuals may be rated under the most appropriate rating code. Further, if medication is discontinued and symptoms reappear, the disability could again be rated under the schedule for rating disabilities of the endocrine system.

The same commenter suggested that proposed DC 7912 should account for residuals of common treatment procedures such as the Whipple procedure, which is also used for the treatment of pancreatic cancer. VA regulations allow for secondary service connection for disabilities that are proximately due to or the result of a service-connected disease or injury (see 38 CFR 3.310(a)). Disabilities that are secondarily service connected and have distinguishable symptoms, to include disabilities that arise from the treatment of a service-connected disability, are rated separately under the VA rating schedule. Therefore, VA makes no changes based on this comment.

The same commenter proposed that VA amend DCs 7901 and 7902 to account for the specific characteristics of disfigurement due to thyroid enlargement rather than rating such disfigurement under DC 7800 because the criteria in DC 7800 do not match the features of thyroid enlargement. The commenter provided two examples of this alleged inconsistency, cystic thyroid nodules requiring draining and soft swelling of the neck. If disfigurement related to thyroid enlargement does not satisfy the criteria in DC 7800, the disfigurement does not result in impairment of earning capacity and is not compensable (see 38 U.S.C. 1155). Therefore, VA makes no changes based on these comments.

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

We are additionally adding updates to 38 CFR part 4, Appendices A, B, and C, to reflect changes to the endocrine system rating criteria made by this rulemaking. The appendices are tools for users of the VASRD and do not contain substantive content regarding evaluation of disabilities. As such, we believe it is appropriate to include these updates in this final rule.

Benefits Costs

The change to the proposed rule will not alter the estimated costs provided in the previous Notice of Proposed Rulemaking.

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 December 10, 2017, the date VBMS-R system updates related to this final rule will be complete.

Executive Orders 12866 and 13563

Executive Orders 13563 and 12866 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 have 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 directly 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).

Catalog of Federal Domestic Assistance

The Catalog of Federal Domestic Assistance program numbers and titles for this rule are 64.009, Veterans Medical Care Benefits; 64.104, Pension for Non-Service-Connected Disability for Veterans; 64.109, Veterans Compensation for Service-Connected Disability; and 64.110, Veterans Dependency and Indemnity Compensation for Service-Connected Death.
