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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
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.
