Insurers Got a Year and a Half of Breathing Room on the Law That's Supposed to Cover Your Treatment

The Mental Health Parity and Addiction Equity Act has been federal law since 2008. It says your insurer can’t make it harder to get addiction treatment covered than it makes to get a knee surgery covered. It has never once meant your insurer couldn’t try.

The law didn’t change this month. Who’s checking whether anyone follows it did.

The Departments of Labor, HHS, and Treasury agreed to pause enforcement of the 2024 MHPAEA Final Rule’s newer requirements while litigation over the rule and a broader reconsideration play out — even though the rule’s plan-level obligations technically took effect January 1, 2026. In practice, that means the specific tools regulators built to catch insurers imposing tighter prior-authorization rules, stricter visit limits, or narrower networks on addiction and mental health care than on medical care — the comparative-analysis documentation requirements, the enforcement teeth — aren’t being used right now. The rule is on the books. It’s not being checked.

Rep. Tom Kean Jr. introduced the Mental Health Parity Enforcement and Funding Act on June 30 to give the Department of Labor explicit statutory authority to investigate and penalize violations directly, instead of relying on the current patchwork where DOL can flag a violation but enforcement largely depends on the plan sponsor’s cooperation or a member’s own lawsuit. The bill hasn’t moved. Insurers, in the meantime, aren’t required to prove they’re complying with anything they weren’t already required to prove before 2024 — because nobody’s asking them to.

If you’ve had a treatment authorization denied or delayed this year and it felt arbitrary, this is a real part of why: the specific federal mechanism built to make that harder just isn’t running. That doesn’t mean parity law disappeared — it means proving a violation now falls more on you, your provider’s billing office, or your state insurance commissioner than on a federal auditor. If a claim gets denied, ask the plan directly for its comparative analysis on that specific limit; MHPAEA still requires them to produce one on request, enforcement pause or not.

For case managers: this is the week to start a denial log per payer, not after the third client hits the same wall. Patterns are what eventually move a state insurance commissioner — a single denial rarely does.
