State-specific notes
Missouri's 2010 mandate covers through age 18 with $40K ABA cap. Missouri Medicaid (MO HealthNet) covers autism services. St. Louis and Kansas City metros have strong provider density; rural Missouri more limited. Missouri's Thompson Center for Autism at the University of Missouri is a major specialty hub.
State-specific appeals notes
Missouri Department of Commerce and Insurance Consumer Affairs Division. External review through state-contracted IRO.
Important caveats: data current as of May 2026 and verified to the best of our research capacity, but annual statutory changes, plan-specific variations, and ERISA self-funded plan exemptions may affect your specific coverage. Always verify with your plan and your state insurance commissioner before relying on these figures for an appeal.
If you've been denied in Missouri
- Request the denial in writing from your insurer. Federal law (ERISA + ACA) requires this for all denials. Without the written denial you cannot file an appeal.
- File the internal appeal first with your insurer. Most plans require this before external review. Time limits typically 30-180 days from denial — check your denial letter.
- External independent review after internal appeal denial. Most states have a state-administered or insurer-contracted independent review organization (IRO) process that is free and binding.
- State insurance commissioner complaint — file with the Missouri Department of Insurance (contact above). The commissioner can investigate insurer practices and order corrective action.
- EEOC / DOJ complaint if your coverage denial relates to employment-based discrimination.
- Private right of action for ERISA violations or breach of contract is available with an attorney if all administrative paths have failed.

Federal frameworks that apply in every state
- Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) — behavioral health benefits must be provided at parity with medical/surgical benefits. Autism is a behavioral health condition. Coverage limits applied to autism services more restrictively than to medical/surgical services may violate parity.
- Affordable Care Act (ACA) — essential health benefits include behavioral health services. Most plans regulated under ACA must cover autism treatment to some degree.
- ERISA — for employer-sponsored plans, ERISA provides procedural protections and right to appeal. Self-funded ERISA plans are exempt from state insurance mandates but still bound by federal parity laws.
- EPSDT (Medicaid) — Early and Periodic Screening, Diagnostic, and Treatment requires Medicaid to cover medically necessary services for children up to age 21, including autism services. This is often the strongest coverage path for Medicaid-eligible children.
