Autism / ABA Therapy Insurance Denial Appeals
Applied Behavior Analysis (ABA) therapy denials often cite medical necessity or plan exclusions, and some states impose their own autism coverage mandates that layer on top of federal parity protections. Plan type — fully-insured versus self-funded ERISA — determines which framework governs the appeal.

Does MHPAEA require insurance to cover ABA therapy?
MHPAEA does not mandate any specific benefit — but if a plan covers ABA therapy, MHPAEA requires that coverage to be provided on parity with medical/surgical benefits: no stricter visit caps, prior-authorization requirements, or medical necessity criteria than apply to comparable medical services.
My patient has a self-funded ERISA employer plan. Does a state autism mandate still help?
State autism mandates are generally preempted by ERISA for self-funded plans, but federal MHPAEA still applies. If the plan covers any mental health or SUD treatment, it cannot impose more restrictive limitations on ASD-related services than on comparable medical/surgical benefits.
The plan denied ABA-related psychotherapy, calling autism 'not a covered behavioral health condition.' Is that a parity issue?
This can be a parity issue. Selectively excluding autism spectrum disorder from covered behavioral health diagnoses while covering other conditions is a diagnosis-based exclusion — exactly the kind of non-quantitative treatment limitation MHPAEA's comparative-analysis requirement is meant to surface.
