You found out your child qualifies for ABA therapy. Then someone mentioned Medicaid — and suddenly there’s a new set of questions. What does Medicaid actually cover? What does the process look like? How do you start?

If you’ve been sitting with those questions, this guide is for you. Both Texas and Illinois cover ABA — Applied Behavior Analysis — therapy through their Medicaid programs. The coverage is real, it can cover the full cost of care, and it’s designed for families exactly like yours. The process has steps, but each one is manageable, and you don’t have to figure it out alone.

Here’s exactly what Medicaid covers for ABA therapy in Texas and Illinois, and how to navigate the authorization process — from eligibility all the way to your child’s first session.

What Medicaid Coverage for ABA Therapy Actually Means

Medicaid is not a discount program — it is full health insurance for qualifying families. When ABA therapy is covered, it means the state pays for your child’s sessions, assessments, and treatment planning directly. Most families with Medicaid coverage pay nothing out of pocket for ABA services.

In most states, ABA coverage for autism falls under a federal framework called EPSDT — Early and Periodic Screening, Diagnostic, and Treatment. This means that if ABA therapy is medically necessary for your child, Medicaid is required to cover it, regardless of cost limits, as long as the child meets eligibility criteria.

Both Texas and Illinois operate under this framework. That’s the foundation that makes coverage possible.

Texas Medicaid and ABA Therapy

When Did Texas Medicaid Start Covering ABA?

Texas Medicaid added ABA therapy coverage on February 1, 2022 — a significant policy change that opened access to thousands of families across the state. ABA is covered under the Texas Health Steps–Comprehensive Care Program (THSteps-CCP), which is the state’s program for medically necessary services for children.

Who Qualifies for Texas Medicaid ABA Coverage?

To access ABA therapy through Texas Medicaid, your child must meet all of the following:

• Active Medicaid enrollment — your child is currently enrolled in a Texas Medicaid plan
• Age range — birth through age 20
• Confirmed ASD diagnosis — from a licensed physician, developmental pediatrician, or psychologist
• Medical necessity determination — a clinician has documented that ABA therapy is necessary to treat your child’s autism

The diagnosis alone is not sufficient to trigger coverage. A treating provider must document that ABA is medically necessary — not just helpful, but clinically indicated. This is a standard documentation requirement, not a barrier. Your ABA provider and referring physician handle this together.

Which Texas Medicaid Plans Cover ABA?

Texas Medicaid is primarily delivered through Managed Care Organizations (MCOs) — insurance plans contracted with the state to provide Medicaid benefits. Most Texas families receive Medicaid through one of these plans, and ABA coverage applies across all of them.

Texas MCOs that cover ABA therapy include:

• Aetna Better Health of Texas
• Molina Healthcare of Texas
• UnitedHealthcare Community Plan of Texas
• Wellpoint (formerly Amerigroup in some regions)
• Community Health Choice
• Superior Health Plan
• Community First Health Plans

Each MCO has its own prior authorization portal and process, but the core eligibility criteria are consistent. Your provider will know which MCO covers your child and will submit to the right plan.

Step-by-Step: How to Get ABA Therapy Through Texas Medicaid

Step 1: Confirm your child’s active Medicaid enrollment and plan name

Before anything else, know which Medicaid plan your child is on. You can find this on your child’s Medicaid card, through Your Texas Benefits (yourtexasbenefits.com), or by calling 211. The plan name matters because the prior authorization process is specific to each MCO.

Step 2: Get a referral or prescription from your child’s physician

Most Texas Medicaid MCOs require a physician’s order before the ABA prior authorization can be processed. Contact your child’s pediatrician or developmental pediatrician and let them know you’d like a referral for ABA therapy. They should document the ASD diagnosis and the medical necessity of ABA in the referral.

Step 3: Contact an ABA provider who accepts your Medicaid plan

Find an ABA therapy provider in Texas that is enrolled in your child’s specific MCO network. When you reach out, let them know your child’s Medicaid plan. Luna Family Autism accepts Medicaid and major insurance plans in Texas — you can check your coverage and start the process through Luna’s team in a single call.

Step 4: Complete the functional behavior assessment

Before prior authorization can be submitted, a Board Certified Behavior Analyst — BCBA — must complete a comprehensive functional behavior assessment. This assessment documents your child’s current skill levels, behavioral patterns, and the clinical rationale for ABA therapy. It forms the foundation of the treatment plan.

Step 5: Submit the prior authorization request

Your ABA provider submits the prior authorization request to your child’s MCO. The submission includes:

• Your child’s Medicaid ID and demographic information
• The ASD diagnosis documentation
• The completed BCBA functional behavior assessment
• The Individualized Treatment Plan (ITP) with goals and recommended service hours
• The physician’s order

This submission is handled by the ABA provider’s clinical and administrative team — not the family. Your job at this stage is to make sure all documentation is in order and that your physician’s referral has been sent to the provider.

Step 6: Wait for authorization and respond to any requests

Most Texas MCOs process prior authorization requests within 14 to 30 business days. Some plans have urgent review tracks for children under age 5. During the review, the MCO may request additional clinical documentation. Your provider should be your point of contact for any follow-up.

As of April 1, 2025, the Texas Medicaid & Healthcare Partnership (TMHP) updated prior authorization requirements for autism services — your provider will be up to date on current requirements.

Step 7: Begin services

Once authorization is approved, your child’s ABA therapy can begin. Do not begin services before the authorization start date — sessions delivered outside the authorization window will not be covered.

What If the Prior Authorization Is Denied?

Denials happen, and they are not final. If your child’s Medicaid plan denies the prior authorization request, you have the right to appeal. Common reasons for denial include incomplete documentation or questions about medical necessity — both are addressable with additional clinical detail from your BCBA and physician.

Your ABA provider should guide you through the appeals process. Under Medicaid, you also have the right to a fair hearing if an appeal is denied.

Illinois Medicaid and ABA Therapy

When Did Illinois Medicaid Start Covering ABA?

Illinois Medicaid has covered ABA therapy since November 1, 2020, through a program called Adaptive Behavior Support (ABS) Services, administered by the Illinois Department of Healthcare and Family Services (HFS). The program covers behavioral assessment, treatment planning, and ongoing behavioral analysis treatment for children with autism.

Who Qualifies for Illinois Medicaid ABA Coverage?

Eligibility requirements for ABA under Illinois Medicaid:

• Active Illinois Medicaid enrollment — including managed care plans and All Kids
• Age range — birth through age 20
• Confirmed ASD diagnosis — from a licensed clinician
• Medical necessity — ABA is clinically indicated for the child’s diagnosis

Illinois also has a state autism insurance mandate under 215 ILCS 5/356z.14 that requires coverage for autism treatment in state-regulated commercial insurance plans for individuals under age 21. For Medicaid families, coverage is through the HFS adaptive behavior services benefit.

Which Illinois Medicaid Plans Cover ABA?

Illinois Medicaid is delivered through two pathways:

All Kids — Illinois’ children’s health insurance program with income-based tiers (Assist, Share, Premium). ABA coverage applies across all tiers, subject to prior authorization.

HealthChoice Illinois managed care plans — Most Medicaid-enrolled children in Illinois are enrolled in a managed care plan. Plans include:

• Meridian Health Plan
• Aetna Better Health of Illinois
• BlueCross Community Health Plans
• Molina Healthcare of Illinois
• CountyCare Health Plan

Coverage varies slightly by plan. Your ABA provider will confirm coverage and network participation before beginning the authorization process.

Step-by-Step: How to Get ABA Therapy Through Illinois Medicaid

Step 1: Confirm your Illinois Medicaid plan

Identify your child’s current Medicaid plan. You can find this on the Medicaid card or by calling the Illinois HFS Member Services line at 1-800-226-0768. Families enrolled in HealthChoice Illinois can also use enrollhfs.illinois.gov to compare plans.

Step 2: Find an ABA provider enrolled in your plan

Contact an ABA therapy provider who accepts Illinois Medicaid and your specific managed care plan. Confirm in-network status before the assessment process begins. Luna Family Autism serves families across Illinois — including Chicago, Springfield, Rockford, Aurora, and surrounding areas via virtual, in-home sessions. You can check your coverage with Luna’s team at no cost and with no commitment.

Step 3: Complete the behavioral assessment

A BCBA must complete a full assessment before prior authorization can be submitted to HFS. Illinois Medicaid covers two types of services that require different authorization pathways:

• Behavioral Assessment (BA) — can begin without prior authorization for a limited period
• Behavior Analysis Treatment Planning (BATP) — requires prior authorization for services exceeding 6 hours per 180-day period
• Behavioral Analysis Intensive (BAI) — all BAI services require prior authorization

Step 4: Submit the prior authorization request to HFS

For services requiring prior authorization, your ABA provider submits the PA request to Illinois HFS at HFS.ABA@Illinois.gov using the HFS Prior Authorization for ABA Services form. Required documentation includes:

• Child’s Medicaid ID and demographics
• ASD diagnosis documentation
• BCBA assessment results and treatment justification
• Proposed treatment goals and service hours

Your provider handles this submission. Your role is to sign any required release forms and ensure your physician has provided the diagnosis documentation.

Step 5: Authorization review and approval

Illinois HFS reviews prior authorization requests and typically processes standard requests within 14 to 21 business days. Urgent or expedited reviews may be processed faster for children under age 5 or in crisis situations. Your provider will follow up on the authorization status.

Step 6: Begin services on the authorized start date

Once authorization is approved, services begin on the date specified in the authorization. You should receive confirmation from both HFS and your ABA provider before the first session.

What If the Prior Authorization Is Denied in Illinois?

If Illinois HFS or your managed care plan denies the prior authorization request, your child has the right to an appeal and a fair hearing. A denial for “lack of medical necessity” can often be overturned with additional clinical documentation from the BCBA and the diagnosing physician. Your provider should have experience navigating appeals and can support you through the process.

What Families Often Ask About Medicaid and ABA

Do I need to do anything before contacting an ABA provider?

The most important thing to have ready is your child’s confirmed ASD diagnosis and your current Medicaid plan information. You don’t need to complete any forms yourself before calling. A good ABA provider will walk you through the rest.

How long does it take from first call to starting therapy?

The timeline depends on how quickly the prior authorization is processed. In most cases, families can expect to begin therapy 4 to 8 weeks after the initial intake call, assuming documentation is in order. Some plans have expedited review tracks. Luna’s virtual model — sessions happen in your home via secure video — means there’s no facility scheduling to coordinate, which shortens the time between authorization approval and your first session.

Can ABA therapy be delivered virtually and still be covered by Medicaid?

Yes. Telehealth ABA therapy is a covered service under Medicaid in both Texas and Illinois. Research published in Pediatrics by Lindgren and colleagues demonstrated that parents can use ABA procedures to successfully reduce challenging behaviors regardless of whether the BCBA is present in person or via remote video — outcomes were equivalent. Virtual delivery is not a compromise; for many families, it produces faster skill generalization because therapy happens in the actual environment where skills are needed.

What if I’m on a managed care plan and my preferred ABA provider isn’t in-network?

If your preferred provider is out of network for your specific MCO, you may have options. In some cases, families can request an in-network exception or single-case agreement. You can also ask your managed care plan to assist with finding an in-network ABA provider. Luna is enrolled with multiple Medicaid MCOs in Texas and Illinois — ask about your specific plan when you call.

Does Medicaid cover the initial assessment?

Yes. The initial functional behavior assessment (FBA) by a BCBA is covered as part of the ABA benefit in both states. This is important — the assessment is not a fee-for-service step families need to pay for separately.

What if my child doesn’t qualify for Medicaid?

Families who don’t qualify for Medicaid may still have strong ABA coverage through commercial insurance. Texas and Illinois both have autism insurance mandates for private insurance plans. Luna accepts major commercial insurers including BCBS, Cigna, and others in both states. You can learn more about Luna’s full insurance and coverage overview.
