United States Code, 2024 Edition Title 26 - INTERNAL REVENUE CODE Subtitle K - Group Health Plan Requirements CHAPTER 100 - GROUP HEALTH PLAN REQUIREMENTS Subchapter B - Other Requirements Sec. 9812 - Parity in mental health and substance use disorder benefits From the U.S. Government Publishing Office, www.gpo.gov §9812. Parity in mental health and substance use disorder benefits (a) In general (1) Aggregate lifetime limits In the case of a group health plan that provides both medical and surgical benefits and mental health or substance use disorder benefits— (A) No lifetime limit If the plan does not include an aggregate lifetime limit on substantially all medical and surgical benefits, the plan may not impose any aggregate lifetime limit on mental health or substance use disorder benefits. (B) Lifetime limit If the plan includes an aggregate lifetime limit on substantially all medical and surgical benefits (in this paragraph referred to as the "applicable lifetime limit"), the plan shall either— (i) apply the applicable lifetime limit both to the medical and surgical benefits to which it otherwise would apply and to mental health and substance use disorder benefits and not distinguish in the application of such limit between such medical and surgical benefits and mental health and substance use disorder benefits; or (ii) not include any aggregate lifetime limit on mental health or substance use disorder benefits that is less than the applicable lifetime limit. (C) Rule in case of different limits In the case of a plan that is not described in subparagraph (A) or (B) and that includes no or different aggregate lifetime limits on different categories of medical and surgical benefits, the Secretary shall establish rules under which subparagraph (B) is applied to such plan with respect to mental health and substance use disorder benefits by substituting for the applicable lifetime limit an average aggregate lifetime limit that is computed taking into account the weighted average of the aggregate lifetime limits applicable to such categories. (2) Annual limits In the case of a group health plan that provides both medical and surgical benefits and mental health or substance use disorder benefits— (A) No annual limit If the plan does not include an annual limit on substantially all medical and surgical benefits, the plan may not impose any annual limit on mental health or substance use disorder benefits. (B) Annual limit If the plan includes an annual limit on substantially all medical and surgical benefits (in this paragraph referred to as the "applicable annual limit"), the plan shall either— (i) apply the applicable annual limit both to medical and surgical benefits to which it otherwise would apply and to mental health and substance use disorder benefits and not distinguish in the application of such limit between such medical and surgical benefits and mental health and substance use disorder benefits; or (ii) not include any annual limit on mental health or substance use disorder benefits that is less than the applicable annual limit. (C) Rule in case of different limits In the case of a plan that is not described in subparagraph (A) or (B) and that includes no or different annual limits on different categories of medical and surgical benefits, the Secretary shall establish rules under which subparagraph (B) is applied to such plan with respect to mental health and substance use disorder benefits by substituting for the applicable annual limit an average annual limit that is computed taking into account the weighted average of the annual limits applicable to such categories. (3) Financial requirements and treatment limitations (A) In general In the case of a group health plan that provides both medical and surgical benefits and mental health or substance use disorder benefits, such plan shall ensure that— (i) the financial requirements applicable to such mental health or substance use disorder benefits are no more restrictive than the predominant financial requirements applied to substantially all medical and surgical benefits covered by the plan, and there are no separate cost sharing requirements that are applicable only with respect to mental health or substance use disorder benefits; and (ii) the treatment limitations applicable to such mental health or substance use disorder benefits are no more restrictive than the predominant treatment limitations applied to substantially all medical and surgical benefits covered by the plan and there are no separate treatment limitations that are applicable only with respect to mental health or substance use disorder benefits. (B) Definitions In this paragraph: (i) Financial requirement The term "financial requirement" includes deductibles, copayments, coinsurance, and out-of-pocket expenses, but excludes an aggregate lifetime limit and an annual limit subject to paragraphs (1) and (2). (ii) Predominant A financial requirement or treatment limit is considered to be predominant if it is the most common or frequent of such type of limit or requirement. (iii) Treatment limitation The term "treatment limitation" includes limits on the frequency of treatment, number of visits, days of coverage, or other similar limits on the scope or duration of treatment. (4) Availability of plan information The criteria for medical necessity determinations made under the plan with respect to mental health or substance use disorder benefits shall be made available by the plan administrator in accordance with regulations to any current or potential participant, beneficiary, or contracting provider upon request. The reason for any denial under the plan of reimbursement or payment for services with respect to mental health or substance use disorder benefits in the case of any participant or beneficiary shall, on request or as otherwise required, be made available by the plan administrator to the participant or beneficiary in accordance with regulations. (5) Out-of-network providers In the case of a plan that provides both medical and surgical benefits and mental health or substance use disorder benefits, if the plan provides coverage for medical or surgical benefits provided by out-of-network providers, the plan shall provide coverage for mental health or substance use disorder benefits provided by out-of-network providers in a manner that is consistent with the requirements of this section. (6) Compliance program guidance document (A) In general The Secretary, the Secretary of Health and Human Services, and the Secretary of Labor, in consultation with the Inspector General of the Department of Health and Human Services, the Inspector General of the Department of Labor, and the Inspector General of the Department of the Treasury, shall issue a compliance program guidance document to help improve compliance with this section, section 2726 of the Public Health Service Act, and section 712 of the Employee Retirement Income Security Act of 1974, as applicable. In carrying out this paragraph, the Secretaries may take into consideration the 2016 publication of the Department of Health and Human Services and the Department of Labor, entitled "Warning Signs - Plan or Policy Non-Quantitative Treatment Limitations (NQTLs) that Require Additional Analysis to Determine Mental Health Parity Compliance". (B) Examples illustrating compliance and noncompliance (i) In general The compliance program guidance document required under this paragraph shall provide illustrative, de-identified examples (that do not disclose any protected health information or individually identifiable information) of previous findings of compliance and noncompliance with this section, section 2726 of the Public Health Service Act, or section 712 of the Employee Retirement Income Security Act of 1974, as applicable, based on investigations of violations of such sections, including— (I) examples illustrating requirements for information disclosures and nonquantitative treatment limitations; and (II) descriptions of the violations uncovered during the course of such investigations. (ii) Nonquantitative treatment limitations To the extent that any example described in clause (i) involves a finding of compliance or noncompliance with regard to any requirement for nonquantitative treatment limitations, the example shall provide sufficient detail to fully explain such finding, including a full description of the criteria involved for approving medical and surgical benefits and the criteria involved for approving mental health and substance use disorder benefits. (iii) Access to additional information regarding compliance In developing and issuing the compliance program guidance document required under this paragraph, the Secretaries specified in subparagraph (A)— (I) shall enter into interagency agreements with the Inspector General of the Department of Health and Human Services, the Inspector General of the Department of Labor, and the Inspector General of the Department of the Treasury to share findings of compliance and noncompliance with this section, section 2726 of the Public Health Service Act, or section 712 of the Employee Retirement Income Security Act of 1974, as applicable; and (II) shall seek to enter into an agreement with a State to share information on findings of compliance and noncompliance with this section, section 2726 of the Public Health Service Act, or section 712 of the Employee Retirement Income Security Act of 1974, as applicable.

(B) Small employer For purposes of subparagraph (A), the term "small employer" means, with respect to a calendar year and a plan year, an employer who employed an average of at least 2 (or 1 in the case of an employer residing in a State that permits small groups to include a single individual) but not more than 50 employees on business days during the preceding calendar year. For purposes of the preceding sentence, all persons treated as a single employer under subsection (b), (c), (m), or (o) of section 414 shall be treated as 1 employer and rules similar to rules of subparagraphs (B) and (C) of section 4980D(d)(2) shall apply. (2) Cost exemption (A) In general With respect to a group health plan, if the application of this section to such plan results in an increase for the plan year involved of the actual total costs of coverage with respect to medical and surgical benefits and mental health and substance use disorder benefits under the plan (as determined and certified under subparagraph (C)) by an amount that exceeds the applicable percentage described in subparagraph (B) of the actual total plan costs, the provisions of this section shall not apply to such plan during the following plan year, and such exemption shall apply to the plan for 1 plan year. An employer may elect to continue to apply mental health and substance use disorder parity pursuant to this section with respect to the group health plan involved regardless of any increase in total costs. (B) Applicable percentage With respect to a plan, the applicable percentage described in this subparagraph shall be— (i) 2 percent in the case of the first plan year in which this section is applied; and (ii) 1 percent in the case of each subsequent plan year. (C) Determinations by actuaries Determinations as to increases in actual costs under a plan for purposes of this section shall be made and certified by a qualified and licensed actuary who is a member in good standing of the American Academy of Actuaries. All such determinations shall be in a written report prepared by the actuary. The report, and all underlying documentation relied upon by the actuary, shall be maintained by the group health plan for a period of 6 years following the notification made under subparagraph (E). (D) 6-month determinations If a group health plan seeks an exemption under this paragraph, determinations under subparagraph (A) shall be made after such plan has complied with this section for the first 6 months of the plan year involved. (E) Notification (i) In general A group health plan that, based upon a certification described under subparagraph (C), qualifies for an exemption under this paragraph, and elects to implement the exemption, shall promptly notify the Secretary, the appropriate State agencies, and participants and beneficiaries in the plan of such election. (ii) Requirement A notification to the Secretary under clause (i) shall include— (I) a description of the number of covered lives under the plan involved at the time of the notification, and as applicable, at the time of any prior election of the cost-exemption under this paragraph by such plan; (II) for both the plan year upon which a cost exemption is sought and the year prior, a description of the actual total costs of coverage with respect to medical and surgical benefits and mental health and substance use disorder benefits under the plan; and (III) for both the plan year upon which a cost exemption is sought and the year prior, the actual total costs of coverage with respect to mental health and substance use disorder benefits under the plan. (iii) Confidentiality A notification to the Secretary under clause (i) shall be confidential. The Secretary shall make available, upon request and on not more than an annual basis, an anonymous itemization of such notifications, that includes— (I) a breakdown of States by the size and type of employers submitting such notification; and (II) a summary of the data received under clause (ii). (F) Audits by appropriate agencies To determine compliance with this paragraph, the Secretary may audit the books and records of a group health plan relating to an exemption, including any actuarial reports prepared pursuant to subparagraph (C), during the 6 year period following the notification of such exemption under subparagraph (E). A State agency receiving a notification under subparagraph (E) may also conduct such an audit with respect to an exemption covered by such notification. (d) Separate application to each option offered In the case of a group health plan that offers a participant or beneficiary two or more benefit package options under the plan, the requirements of this section shall be applied separately with respect to each such option. (e) Definitions For purposes of this section: (1) Aggregate lifetime limit The term "aggregate lifetime limit" means, with respect to benefits under a group health plan, a dollar limitation on the total amount that may be paid with respect to such benefits under the plan with respect to an individual or other coverage unit. (2) Annual limit The term "annual limit" means, with respect to benefits under a group health plan, a dollar limitation on the total amount of benefits that may be paid with respect to such benefits in a 12-month period under the plan with respect to an individual or other coverage unit. (3) Medical or surgical benefits The term "medical or surgical benefits" means benefits with respect to medical or surgical services, as defined under the terms of the plan, but does not include mental health or substance use disorder benefits. (4) Mental health benefits The term "mental health benefits" means benefits with respect to services for mental health conditions, as defined under the terms of the plan and in accordance with applicable Federal and State law.
