Title 26 › Subtitle K — Group Health Plan Requirements › CHAPTER 100 — GROUP HEALTH PLAN REQUIREMENTS › Subchapter B — Other Requirements › § 9812
Require group health plans that cover both regular medical care and mental health or addiction treatment to treat those benefits the same in key ways. If a plan has no lifetime or yearly dollar limits on most medical care, it cannot put such limits on mental health or substance use disorder (SUD) care. If the plan does have a lifetime or yearly dollar limit on most medical care, it must either apply the same limit to mental health and SUD care or set a mental health/SUD limit that is not lower than the medical limit. Plans must not make people pay more or face stricter treatment limits for mental health or SUD care than the most common cost or treatment limits that apply to medical care, and they may not have separate cost-sharing or treatment rules only for mental health or SUD care. Plans must make the rules used to decide medical necessity for mental health and SUD care available on request. If a plan covers out-of-network medical care, it must also cover out-of-network mental health and SUD care in a matching way. Starting 45 days after the date of enactment of the Consolidated Appropriations Act, 2021, plans that use nonquantitative treatment limits (NQTLs) for mental health or SUD benefits must do and keep written comparative analyses showing that those limits are applied no more strictly than for medical care, and must give those analyses to the Secretary on request. The Secretary must ask for at least 20 such analyses each year, may require fixes if a plan is found not in compliance, and a plan that stays noncompliant after a 45‑day correction period must notify enrollees within 7 days after the final finding. The Departments must issue guidance and a compliance program document with de‑identified examples, update it every 2 years, allow at least a 60‑day public comment period before final guidance, and finalize related guidance and rules within 18 months. The Secretary must report to Congress within 1 year after enactment and each year thereafter (by October 1) about requests, findings, and actions. Allow two types of exemptions. Small employers are exempt if they had on average at least 2 (or 1 in States that allow single‑person groups) but not more than 50 employees in the prior year. A plan may be exempt for one year if following parity would raise total plan costs for medical and mental health/SUD benefits by more than the applicable percentage: 2 percent for the first year and 1 percent for later years. Cost increases must be certified in a written report by a qualified, licensed actuary who is a member in good standing of the American Academy of Actuaries; the plan must keep the report and supporting documents for 6 years. Determinations for a cost exemption are made after the plan has followed the rules for the first 6 months of the plan year. Plans that claim an exemption must notify the Secretary, state agencies, and enrollees; the submission to the Secretary is confidential but may be audited by federal or state agencies. Definitions in this rule include aggregate lifetime limit, annual limit, medical or surgical benefits, mental health benefits, and substance use disorder benefits (each defined by simple meaning in the plan and law).
