Does Insurance Cover ABA Therapy in Illinois?

Private Insurance

Illinois is one of the states with a comprehensive autism insurance mandate. Under Illinois law (Public Act 096-1465), most group health insurance plans must cover the diagnosis and treatment of autism spectrum disorder, including ABA therapy. This mandate applies to plans regulated by the state, including those offered by large employers, small businesses, and individual market plans. Self-funded employer plans (ERISA) are not subject to state mandates, but many still choose to offer ABA coverage.

Coverage details vary by plan. Some plans may have limits on the number of hours per week or an annual dollar cap. Others may require prior authorization or a referral. It is essential to contact your insurance company directly to understand your specific benefits. If you need help navigating insurance, Get ABA Therapy can match you with providers who are experienced in working with your plan.

Medicaid (Illinois Medicaid)

Illinois Medicaid, administered by the Department of Healthcare and Family Services (HFS), covers ABA therapy for eligible children under age 21. Through the Home and Community-Based Services (HCBS) waiver or the state plan, children with autism can receive medically necessary ABA services. There is no cost-sharing for most Medicaid-covered services, meaning families typically pay nothing out-of-pocket for ABA therapy.

To qualify, a child must have a diagnosis of autism and meet income and resource limits, or be eligible through other pathways such as being in foster care or receiving Supplemental Security Income (SSI). Once enrolled, families can choose from a network of BCBA-led providers. Get ABA Therapy can help you find providers who accept Illinois Medicaid in your area.

Early Intervention

For children under age 3, Illinois' Early Intervention (EI) program, administered by the Illinois Department of Human Services (IDHS), may cover ABA therapy as part of an Individualized Family Service Plan (IFSP). EI services are provided at no cost to families, though some may be billed on a sliding scale based on income. If your child is under 3 and you suspect a developmental delay or have a diagnosis, contact the Child and Family Connections (CFC) office in your region to request an evaluation.

How Much Does ABA Therapy Cost Without Insurance?

Without insurance coverage, families often pay for ABA therapy out-of-pocket. In Illinois, private-pay rates for ABA therapy typically range from $60 to $120 per hour for services provided by a Board Certified Behavior Analyst (BCBA) or a qualified behavior technician under BCBA supervision. The exact rate depends on the provider's experience, location (urban areas like Chicago tend to be higher), and the specific type of service (e.g., center-based vs. in-home).

For a child receiving 20 hours of therapy per week, monthly costs could range from $4,800 to $9,600. This is a significant expense for most families, which is why exploring insurance or Medicaid coverage is so important. Some providers offer sliding scale fees or payment plans, but availability is limited. If you are paying privately, always ask for a written estimate and clarify what services are included.

Get ABA Therapy can help you find providers who offer competitive private-pay rates and discuss payment options during your free consultation.

Factors That Influence the Cost of ABA Therapy

  • Provider qualifications: BCBAs typically charge higher rates than Board Certified Assistant Behavior Analysts (BCaBAs) or registered behavior technicians (RBTs).
  • Setting: Center-based therapy often costs more than in-home or school-based services due to overhead expenses.
  • Intensity: More hours per week mean higher total costs, though some providers offer tiered pricing.
  • Location: Providers in Chicago and suburbs may charge more than those in rural areas.
  • Assessment and supervision: Initial assessments and ongoing BCBA supervision are usually billed separately and can add to the total cost.
  • Insurance network: In-network providers often have negotiated rates that are lower than out-of-network charges.

How to Get ABA Therapy Covered by Insurance

Getting insurance to cover ABA therapy takes some steps, but it is very doable. Start by obtaining a formal autism diagnosis from a qualified professional (e.g., developmental pediatrician, child psychologist). Then, contact your insurance company to ask about ABA therapy benefits. Key questions to ask:

  • Is ABA therapy a covered benefit under my plan?
  • Do I need a referral or prior authorization?
  • What is the annual or lifetime cap on ABA coverage?
  • Are there in-network providers I must use?
  • What documentation is required (e.g., treatment plan, progress reports)?

If you have difficulty navigating the process, Get ABA Therapy can connect you with providers who have dedicated insurance specialists to help you verify benefits and obtain authorization. The service is completely free for families.
