Title 29 › Chapter CHAPTER 18— - EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › Subchapter SUBCHAPTER I— - PROTECTION OF EMPLOYEE BENEFIT RIGHTS › Subtitle Subtitle B— - Regulatory Provisions › Part part 7— - group health plan requirements › Subpart Subpart B— - Other Requirements › § 1185a
Group health plans that cover both regular medical care and mental health or substance use care must treat the two kinds of benefits the same. If the plan has no overall lifetime dollar cap on most medical and surgical care, it cannot put a lifetime cap on mental health or substance use care. If the plan does have a lifetime cap on most medical and surgical care, it must either apply that same cap to mental health and substance use care or make any cap for those benefits at least as large. The same rules apply to yearly dollar caps. Cost sharing (like deductibles, copays, coinsurance, and out‑of‑pocket limits) and limits on treatment (like number of visits or days covered) for mental health and substance use care must be no tougher than the main rules used for medical and surgical care. Plans must share their medical‑necessity rules and the reasons for any denial when a participant, potential participant, or provider asks. If the plan covers out‑of‑network medical care, it must cover out‑of‑network mental health and substance use care in the same way. Federal agencies must give plans help and examples to follow and must update that guidance every 2 years. They must publish a compliance guide with de‑identified examples and accept public comment for at least 60 days before finalizing guidance. Plans that use nonquantitative rules (like medical management, formularies, or step therapy) must do and keep written comparative analyses showing those rules are applied no more strictly to mental health or substance use care; starting 45 days after December 27, 2020, those analyses must be given to the Secretary on request. The Secretary will ask for at least 20 analyses each year, may ask for fixes, and if a plan is found not to be following the rules it must try to fix things within 45 days and then notify enrollees within 7 days if it still fails. The Secretary must report to Congress not later than 1 year after December 27, 2020 and then by October 1 each year, and must finish related guidance within 18 months after December 27, 2020. Small employers (those with on average 2 — or 1 in some States — up to 50 employees) are generally exempt. A plan may skip the rules for one year if a licensed actuary shows parity would raise total costs by more than 2 percent in the first year or more than 1 percent in later years, and such an exemption must be documented and reported. Definitions (one line each): aggregate lifetime limit — a dollar cap on total benefits paid over a lifetime; annual limit — a dollar cap on benefits paid in a 12‑month period; medical or surgical benefits — regular medical/surgical services under the plan; mental health benefits — services for mental health conditions under the plan; substance use disorder benefits — services for substance use disorders under the plan.
