ABA Therapy Insurance Coverage in Indiana
Understand how ABA therapy is covered in your state — including Medicaid, private insurance, and the autism insurance mandate.
Updated Jun 8, 2026
The three coverage paths in Indiana
Most families in Indiana get ABA therapy covered one of three ways: state Medicaid (including waiver programs), a state-regulated private plan subject to the autism insurance mandate, or a self-funded employer plan regulated by federal ERISA rules. Coverage rules differ depending on which one you have.
Medicaid in Indiana
For children under 21, Indiana Medicaid covers medically necessary ABA through the federal EPSDT benefit (Early and Periodic Screening, Diagnostic, and Treatment). You generally need an autism spectrum disorder diagnosis from a qualified provider and a written treatment plan. Indiana may also offer disability-specific waivers (sometimes called Katie Beckett or TEFRA-style waivers) that allow children with significant needs to qualify regardless of household income.
Private insurance and the autism mandate
All 50 states have passed some form of autism insurance mandate, but the details — age caps, dollar limits, and which plans are covered — vary. The mandate applies to state-regulated, fully insured plans purchased in Indiana. Self-funded employer plans (common at large companies) follow federal law instead and are not bound by Indiana's mandate, though many cover ABA voluntarily.
Ask HR whether your plan is fully insured or self-funded. The answer determines which appeal rights and external review options you have.
