Getting Autism Therapy Covered by Insurance in Indiana

Indiana’s mandate

Ind. Code 27-8-14.2, enacted 2001, requires state-regulated health plans in Indiana to cover the diagnosis and treatment of autism spectrum disorder, including applied behavior analysis.

Ages covered: The statute sets no age limit, which is unusual for a mandate this old.

Dollar cap: None in the statute. Indiana also bars limiting ABA to a set number of calendar days — it must be available year-round, which blocks the common tactic of approving therapy only during the school year.

Two exemptions catch Indiana families out. Self-insured employers are exempt, as everywhere. Less obviously, a group plan issued under ANOTHER state's law is also exempt even when it covers Indiana employees — so a large employer headquartered elsewhere may leave you outside the mandate entirely. Ask HR which state your plan was issued in, not just where you work. School-based therapy is also outside the mandate.

Whether the mandate applies to your plan

This is the question to settle first, because the answer decides whether anything above is enforceable for you. State insurance mandates bind fully insured plans. Self-funded employer plans — where the employer pays claims itself and an insurer only administers them — are generally exempt under federal ERISA, and they cover roughly six in ten people with employer coverage.

Ask your HR department, in writing, which type your plan is. If it is self-funded, Ind. Code 27-8-14.2 does not compel coverage — but federal parity law may still help, and many large self-funded employers cover ABA voluntarily. Ask what the plan actually covers rather than assuming the answer is no.

The Medicaid route

Indiana Medicaid covers ABA for members under 21 under federal EPSDT rules, separately from this mandate.

How Medicaid waivers work covers the route for families who do not qualify on income alone.

When you are denied

1. Get the denial reason in writing. Insurers must give a specific reason, and the appeal has to answer that reason rather than restate the diagnosis.
2. File the internal appeal within the deadline on the denial letter, with a letter of medical necessity that addresses the stated reason directly.
3. Request external review if the internal appeal fails. Fully insured plans carry external review rights, and an independent reviewer overturns denials more often than families expect.
4. Complain to the Indiana Department of Insurance on 1-800-622-4461 if you believe Ind. Code 27-8-14.2 is being violated. Their consumer pages are here.
