Understanding ABA Therapy and Its Importance
Applied Behavior Analysis (ABA) therapy is a scientifically validated approach to understanding and changing behavior. For autistic individuals, ABA can help build communication, social, and daily living skills while reducing challenging behaviors. It is widely recognized as an evidence-based treatment for autism spectrum disorder (ASD).
However, the cost of ABA therapy can be significant, often ranging from $50 to $150 per hour. This makes insurance coverage essential for many families. If you live in Tennessee and have Medicaid, you may be wondering: does TennCare cover ABA therapy?

Does Tennessee Medicaid (TennCare) Cover ABA Therapy?
Yes, Tennessee Medicaid, known as TennCare, covers ABA therapy for eligible children. This coverage is primarily available through TennCare's managed care organizations (MCOs): BlueCare, Amerigroup, and UnitedHealthcare Community Plan. It is considered a medically necessary treatment under the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit, which requires states to cover all medically necessary services for children under 21.
To qualify, a child must have a medical diagnosis of autism spectrum disorder from a qualified professional (such as a developmental pediatrician or psychologist). The ABA therapy must be prescribed by a doctor and provided by a Board Certified Behavior Analyst (BCBA) or a therapist under BCBA supervision.
What Types of ABA Services Are Covered?
TennCare typically covers a range of ABA services, including:
- Comprehensive assessments - Functional behavior assessments (FBAs) and skill assessments to create a treatment plan.
- Direct one-on-one therapy - Sessions with a registered behavior technician (RBT) or BCBA.
- Parent training and caregiver support - Teaching families strategies to reinforce skills at home.
- Behavior intervention plans - Written plans to address specific behaviors.
- Supervision and case management - BCBA oversight and coordination with other providers.
Are There Any Limits on Coverage?
Under EPSDT, there is no annual cap on ABA therapy hours if deemed medically necessary. However, the number of hours must be justified by the treatment plan and reviewed periodically. Prior authorization is often required, and the provider must submit documentation showing progress.
How to Get ABA Therapy Covered by TennCare
Navigating Medicaid coverage can feel overwhelming, but the process is straightforward with the right steps. Here's how to start:
Step 1: Confirm Your Child's Diagnosis and Eligibility
Your child must have a formal autism diagnosis from a licensed professional. If you don't have one, talk to your pediatrician about a referral for a diagnostic evaluation. Also, ensure your child is enrolled in a TennCare managed care plan. If you're unsure which plan, check your TennCare ID card or call TennCare's customer service.
Step 2: Get a Prescription or Referral
Ask your child's primary care provider (PCP) or specialist to write a prescription for ABA therapy. The prescription should state the diagnosis and recommend ABA as a medically necessary treatment. Some plans may require a specific form.
Step 3: Find a BCBA-Led Provider That Accepts TennCare
Not all ABA providers accept TennCare, so it's important to find one that does. You can search online or call your MCO's provider directory. To simplify the search, Nearby ABA Therapy is a free service that matches families with vetted, BCBA-led providers who accept TennCare. We help you find options in your area without any cost.
Step 4: Complete the Prior Authorization Process
Your chosen provider will typically handle the prior authorization request. They will submit the treatment plan, assessment results, and prescription to your MCO. Approval can take a few days to a few weeks. Once approved, therapy can begin.

What If You Have TennCare and Are an Adult?
TennCare's EPSDT benefit only applies to children under 21. For adults (21 and older) with TennCare, ABA therapy coverage is more limited. Some TennCare MCOs may cover ABA for adults on a case-by-case basis if it is deemed medically necessary, but it is not guaranteed. Adults may need to seek other funding sources or private insurance. If you are an adult seeking ABA, contact your MCO directly to ask about coverage options.
Common Mistakes to Avoid When Seeking Coverage
Many families encounter delays or denials. Here are pitfalls to watch out for:
- Not getting a proper diagnosis - A general developmental delay diagnosis may not qualify. Ensure a specific autism diagnosis is documented.
- Assuming all providers accept TennCare - Always verify with the provider before starting services.
- Missing prior authorization deadlines - Starting therapy without approval can lead to denied claims.
- Not documenting medical necessity - The treatment plan must clearly show why ABA is needed and how it will help.
- Ignoring your MCO's specific rules - Each MCO (BlueCare, Amerigroup, UnitedHealthcare) may have slightly different requirements. Read your plan's policy.

What If Your ABA Therapy Claim Is Denied?
Denials happen, but you have options. First, review the denial letter to understand the reason (e.g., missing documentation, not medically necessary). Then:
- Contact your provider - They can resubmit with additional information.
- File an appeal - TennCare has an appeals process. You typically have 30 days from the denial date to request a review.
- Seek help - The Tennessee Department of Health or a patient advocate can assist.
Nearby ABA Therapy can also help you find providers experienced with TennCare appeals, making the process smoother.
