### §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.
