Title 29 › CHAPTER 18 — EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › SUBCHAPTER I — PROTECTION OF EMPLOYEE BENEFIT RIGHTS › Subtitle B — Regulatory Provisions › part 7 — group health plan requirements › Subpart B — Other Requirements › § 1185a
Requires group health plans that cover both regular medical care and mental health or substance use disorder care to treat those mental health and substance use benefits the same as medical care. If a plan has no overall lifetime or yearly dollar caps on most medical benefits, it cannot put such caps on mental health or substance use benefits. If the plan does have caps on most medical benefits, it must either apply those same caps to mental health and substance use care or make sure any caps on those services are at least as high. Copays, deductibles, coinsurance, out‑of‑pocket costs, and limits on visits or days of care for mental health and substance use services must be no stricter than the main ones used for medical services. Plans must share the rules they use to decide medical necessity for mental health and substance use care and must explain reasons for any denial. If a plan covers out‑of‑network medical care, it must also cover out‑of‑network mental health and substance use care in a consistent way. Federal agencies must give guidance, examples, and a compliance program, update it every 2 years, and allow at least 60 days for public comment before final guidance. Plans that use nonquantitative treatment limits (NQTLs) must do and keep written comparative analyses showing how those limits are designed and used for mental health and medical care, and, starting 45 days after December 27, 2020, must give those analyses to the Secretary on request. The Secretary must ask for at least 20 analyses each year, can seek more information, require plans to fix problems within 45 days, and if problems remain must notify enrollees within 7 days. Small‑employer plans (average 2—or 1 in some States—up to 50 employees) are exempt. A plan can get a one‑year cost exemption if following the rules raises its total plan costs by more than 2% the first year or more than 1% in later years, but a qualified actuary must certify that and the plan must notify the government, the State, and participants; those records must be kept 6 years and may be audited. Short definitions: aggregate lifetime limit — a dollar cap over a person’s life; annual limit — a dollar cap per 12‑month period; medical or surgical benefits — regular medical services; mental health benefits — services for mental health conditions; substance use disorder benefits — services for substance use problems. The law does not force plans to offer mental health or substance use benefits, and it applies separately to each different benefit option a plan offers.
