Your Insurance Denied ABA Therapy? Here's How to Write an Effective Appeal Letter
In short: If your insurance denies ABA therapy, you have the right to appeal. A strong appeal letter includes a clear explanation of medical necessity, supporting documentation from your BCBA, and references to your plan's coverage criteria. Many denials are overturned on appeal, so don't give up.
Key takeaways
- Insurance denials for ABA therapy are common but often reversible with a well-prepared appeal.
- Your appeal letter must clearly state medical necessity and connect it to your insurance plan's specific coverage language.
- Include a detailed letter of medical necessity from your BCBA, treatment plans, diagnostic reports, and any previous authorizations.
- Follow your insurer's specific appeal process-check deadlines and required forms first.
Why Insurance Denials for ABA Therapy Happen
It's frustrating and stressful when your health insurance plan denies coverage for Applied Behavior Analysis (ABA) therapy. Denials can occur for many reasons: the insurer may say the therapy isn't "medically necessary," claim it's not a covered benefit under your plan, or argue it's "experimental." Sometimes the denial is simply due to missing paperwork or a procedural error. Understanding the reason is the first step to fighting it.

Your Right to Appeal
Under both the Affordable Care Act and most state laws, you have the right to appeal any denial of coverage. This includes private insurance plans (such as those from Blue Cross, UnitedHealthcare, Aetna, Cigna) and many Medicaid plans (like your state's Medicaid program, often called Medicaid or State Children's Health Insurance Program). The appeals process gives you a formal way to challenge the decision and present new evidence.
Before You Write: Gather Key Documents
Understand the Denial Letter
Read the denial letter carefully. It will list the specific reason(s) for denial and may include a reference to a specific policy provision. Write down the exact language used. This will help you tailor your appeal.
Collect Supporting Evidence
A strong appeal is built on evidence. Gather:
- A letter of medical necessity from your BCBA (Board Certified Behavior Analyst) that explains why ABA is needed, the diagnosis (usually autism spectrum disorder), specific goals, and the risks of not providing therapy.
- The treatment plan (behavioral plan) with measurable objectives.
- Diagnostic reports (e.g., from a developmental pediatrician, psychologist, or neurologist).
- Any previous authorizations for ABA (if they existed).
- Letters of support from teachers, speech therapists, or other providers.

How to Write Your Appeal Letter
Structure and Tone
Keep the letter professional and factual. Use a business letter format. Address it to the insurance company's appeals department. Include your name, policy number, claim number, and dates of service. Be polite but assertive.
Key Sections of the Letter
- Opening statement: State that you are appealing the denial of coverage for ABA therapy. Reference the denial letter date and number.
- Medical necessity argument: Explain why ABA therapy is medically necessary for your child. Use the insurer's own criteria if possible. For example: "According to your policy, 'medically necessary' means treatment that is widely accepted and proven effective for the condition. ABA therapy is the gold standard for autism treatment, as recognized by the U.S. Surgeon General and the American Academy of Pediatrics."
- Address the specific reason for denial: If the insurer said it wasn't a covered benefit, point to the mental health parity law or state mandates that require coverage of autism treatment. If they said it was "experimental," cite research and guidelines that prove otherwise.
- Include supporting documentation: Reference the attached BCBA letter, treatment plan, etc.
- Request a specific outcome: Ask that the denial be overturned and that coverage be provided retroactively or going forward.
Sample Phrases You Can Use
"My child was diagnosed with autism spectrum disorder (ASD) by [doctor] on [date]. ABA therapy was prescribed by [BCBA name] to address deficits in communication, social interaction, and adaptive behavior."
"Without this therapy, my child is at risk of regression in skills and increased need for more intensive services later."
"Your denial letter states that ABA is not medically necessary. However, as outlined in the attached letter from [BCBA], the therapy is essential to teach basic safety skills, reduce challenging behaviors, and promote independence."
Timeline and Deadlines
Most insurance plans give you a limited window to appeal-often 30 to 180 days from the date of the denial letter. For Medicaid, the time frame can be as short as 10-15 days for expedited appeals. Check your denial letter or call the insurance company. Submit your appeal as soon as possible. If you miss the deadline, you may lose your right to appeal altogether.
What to Do After You Send the Appeal
After mailing or submitting your appeal online (follow the instructions in the denial letter), keep a copy for your records. Write down the date and method of submission. You should receive a confirmation within a few weeks. If you don't hear back, call to follow up. Many insurance companies must respond within 30 days for standard appeals (or 72 hours for urgent ones).
If Your First Appeal Is Denied: Next Steps
Don't give up. You may have the right to a second-level appeal (internal) and then an external independent review. External reviews are handled by a third party and often have a higher success rate. You can also file a complaint with your state's Department of Insurance or insurance commissioner. Some states have laws that force insurers to cover ABA for autism under certain conditions.
