California autism
insurance coverage.

California at a glance

State-specific notes

California's Mental Health Parity Act and SB 946 (2011) require comprehensive autism behavioral health treatment coverage including ABA. Coverage applies to fully insured plans and CalPERS. Self-funded ERISA plans not bound by state mandate but increasingly include coverage voluntarily. Medi-Cal covers autism services for children through age 21 under EPSDT. Aggressive enforcement track record.

State-specific appeals notes

California has the strongest external review process in the country. After internal appeal denial, request Independent Medical Review (IMR) through the Department of Managed Health Care (1-888-466-2219) within 6 months. IMR decisions are binding on the insurer and free to the consumer.

If you've been denied in California

1. 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.
2. 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.
3. 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.
4. State insurance commissioner complaint — file with the California Department of Insurance (contact above). The commissioner can investigate insurer practices and order corrective action.
5. EEOC / DOJ complaint if your coverage denial relates to employment-based discrimination.
6. 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.
