Illinois Early Intervention ABA Services: What Families Need to Know

What Is Illinois Early Intervention (EI)?

Illinois Early Intervention (EI) is a statewide program that provides services to infants and toddlers (birth to 3 years old) who have developmental delays or diagnosed conditions that are likely to result in delays. The program is administered by the Illinois Department of Human Services (IDHS) and delivered through regional Child and Family Connections (CFC) offices. EI services are designed to support the child's development and help families understand their child's unique needs.

One of the services sometimes available through EI is Applied Behavior Analysis (ABA) therapy, an evidence-based approach that helps children learn new skills and reduce challenging behaviors. ABA is especially effective for children with autism spectrum disorder (ASD). However, ABA is not automatically covered by EI; it must be deemed medically necessary and is typically provided when a child has an autism diagnosis or strong indicators of ASD.

How Does ABA Therapy Fit Into Illinois Early Intervention?

The Role of ABA in Early Intervention

ABA therapy focuses on teaching communication, social, self-help, and play skills while reducing behaviors that interfere with learning. In EI, ABA is often delivered in the child's natural environment-home, daycare, or community-by a Board Certified Behavior Analyst (BCBA) or a supervised therapist. Because EI is family-centered, parents and caregivers learn strategies to support their child's progress throughout the day.

Illinois EI policy states that ABA may be included in the Individualized Family Service Plan (IFSP) if the evaluation team determines it is necessary to address the child's developmental needs. This decision is made on a case-by-case basis. Families should note that EI does not typically cover intensive ABA (e.g., 20-40 hours per week) unless the child has significant needs; more commonly, EI covers a few hours per week of consultation or direct therapy.

Who Is Eligible for ABA Through EI?

Eligibility for EI services in Illinois is based on a documented developmental delay (a 30% or greater delay in one or more areas) or a diagnosed condition (such as autism) that has a high probability of causing a delay. ABA through EI is most often approved for children with an autism diagnosis or who are showing strong red flags for autism. However, approval varies by region and available resources. Families are encouraged to discuss ABA with their CFC service coordinator during the IFSP meeting.

Eligibility and Evaluation Process

Getting an EI Evaluation in Illinois

The first step is to contact your local Child and Family Connections office. You can find the correct CFC office by calling the Illinois EI hotline at 1-800-843-6154 or visiting the IDHS website. A service coordinator will guide you through the intake process. The evaluation itself is provided at no cost to families and is conducted by a multidisciplinary team (e.g., developmental therapist, speech-language pathologist, psychologist).

During the evaluation, the team will assess your child's development in all areas: cognitive, communication, physical, social-emotional, and adaptive. If an autism diagnosis is suspected, a diagnostic evaluation may also be recommended. When the evaluation is complete, the team meets with your family to discuss results and determine if your child qualifies for EI services. If eligible, an IFSP is developed, listing goals and services.

Requesting ABA in the IFSP

To include ABA in the IFSP, you and your service coordinator will need to justify why ABA is medically necessary. This often requires a diagnostic evaluation confirming autism and a recommendation from a physician or psychologist. The IFSP team (including you) will then decide what type and amount of ABA is appropriate. Note that Illinois EI does not have a standardized ABA coverage policy, so persistence and clear documentation are important.

Costs and Insurance Coverage for ABA

EI Services Are Free or Low-Cost

Illinois EI services are provided at no cost to families for evaluation and case management. However, ongoing therapies may have a sliding-scale fee based on family income and insurance status. Many families pay nothing for EI services, especially if they have public insurance (Medicaid) or low income. Private insurance is also billed when possible, and EI can coordinate benefits.

Private Insurance and ABA

Illinois has strong autism insurance reform laws. Most private health insurance plans (including employer-sponsored and individual plans) are required to cover ABA therapy for autism, including for children under age 3. Coverage details vary by plan, so check your benefits. If you have a high deductible plan, you may have out-of-pocket costs, but many plans cover a significant portion of ABA.

Illinois Medicaid and ABA

Illinois Medicaid (HealthChoice Illinois) covers ABA therapy for children with autism. Medicaid often has lower barriers to access than private insurance, though reimbursement rates for providers can be lower, which can affect wait times. If your child qualifies for EI, they may also be eligible for Medicaid regardless of household income through programs like TEFRA (the Tax Equity and Fiscal Responsibility Act).

Because navigating insurance can be overwhelming, Get Started with ABA offers a free service to help you find providers who accept your specific insurance plan and are experienced with early intervention.

Practical Tips for Families Seeking ABA Through EI

• Start the EI process early. Even before a formal autism diagnosis, if you have concerns about your child's development, contact your local CFC office. Early evaluation can open doors to needed services.
• Document everything. Keep records of all evaluations, doctor's notes, and communications with your service coordinator. This helps when advocating for ABA in the IFSP.
• Learn about your rights. The Illinois EI program has procedural safeguards that protect your family's right to disagree with decisions about services. You can request mediation or a due process hearing if needed.
• Ask about family training. Many ABA providers offer parent training as part of the program, which can extend the benefits of therapy beyond professional sessions.
• Explore other funding sources. If EI cannot provide enough ABA hours, look into private insurance, Medicaid, or grants (e.g., from the Illinois Autism Task Force). Some providers offer scholarships.
• Use Get Started with ABA. As noted, our free matching service can help you find providers who understand the Illinois EI system and can coordinate with your CFC team.

Common Mistakes to Avoid

• Waiting for a formal diagnosis. In Illinois, you can start the EI evaluation process without a diagnosis. Delaying can mean missing the critical early window for intervention.
• Assuming EI covers all ABA costs. EI typically covers a limited number of ABA hours. Be realistic and plan to supplement with insurance if possible.
• Not attending IFSP meetings. Your voice is essential. If you cannot attend, ask for a reschedule or to participate by phone. Decisions are made collaboratively, and you are a key team member.
• Choosing a provider without checking credentials. Ensure the provider is BCBA-led and has experience with children under 3. Our matching service vets providers for you.
• Neglecting to verify insurance coverage. Before starting ABA, confirm with both the provider and your insurance that the therapy is covered and that the provider is in-network. Out-of-network costs can be very high.

Frequently Asked Questions

Is ABA therapy always covered by Illinois Early Intervention?

No. ABA is only included in the IFSP if the evaluation team determines it is medically necessary for the child. This is most common for children with an autism diagnosis. Even then, the hours may be limited.

How many hours of ABA does EI typically cover?

There is no set amount. Each IFSP is individualized. For children under 3, EI often provides 2-6 hours per week of direct ABA or parent training, rather than the intensive therapy sometimes seen in older children.

Can I use private insurance for ABA if my child is in EI?

Yes, many families use both EI and private insurance. EI can serve as a supplemental service, or you can opt to pay for additional ABA hours through insurance. Coordination is important to avoid over-billing.

What if my child does not qualify for EI? Can we still get ABA?

Yes. Children over 3 may qualify for school-based services, and ABA is often available through private clinics or home-based providers using insurance. Get Started with ABA can help you find options regardless of age.

How do I find my local Child and Family Connections office?

Call the Illinois EI hotline at 1-800-843-6154 or use the IDHS website provider locator tool. You can also ask your pediatrician for a referral.
