If your child has been diagnosed with autism, one of your first questions is probably about cost. The good news for Illinois families: ABA therapy is covered by most insurance plans by law, and many families pay far less out of pocket than they expect. Here is a clear, up-to-date breakdown of what ABA therapy costs in Illinois and how coverage works.
Is ABA therapy covered by insurance in Illinois?
Yes. Illinois has an autism insurance mandate that requires most state-regulated health plans to cover the diagnosis and treatment of autism spectrum disorder, including medically necessary Applied Behavior Analysis (ABA) therapy. This means that for most families, ABA is a covered medical benefit rather than an out-of-pocket expense.
Coverage details vary by plan type. Fully insured plans regulated by the state must follow the Illinois mandate. Self-funded employer plans are regulated federally and may differ, though many still cover ABA. Medicaid in Illinois also covers medically necessary ABA for eligible children.
What affects your out-of-pocket cost?
- Your deductible — the amount you pay before insurance begins covering services.
- Copays or coinsurance — your share of each session once coverage kicks in.
- In-network vs. out-of-network — in-network providers cost you less.
- Authorized hours — insurers approve a number of therapy hours based on medical necessity.
Because these factors differ for every family, the most reliable way to know your cost is a benefits verification — something we do for you at no charge.
How many hours of ABA will my child need?
There is no one-size-fits-all answer. After a comprehensive assessment, a Board Certified Behavior Analyst (BCBA) recommends an individualized number of hours based on your child’s needs and goals. Younger children in early intervention often benefit from more intensive programming, while others do well with focused, targeted hours.
Ways to lower or manage cost
- Choose an in-network, BCBA-owned provider who handles authorizations for you.
- Ask about telehealth ABA and parent coaching, which can extend progress affordably.
- Use parent training so skills continue between sessions.
- Confirm whether an HSA or FSA can be applied to your share of costs.
