- Gather key documents: your child's autism diagnosis, a letter of medical necessity from a BCBA, and a prescription for ABA therapy.
- File a written appeal with your insurer, using certified mail to ensure proof of receipt and compliance with deadlines.
- If the internal appeal fails, request an independent external review through the Pennsylvania Insurance Department.
What Is an Autism Insurance Appeal in Pennsylvania?
An autism insurance appeal is a formal request to your health insurance company to reverse a denial of coverage for medically necessary autism services, such as Applied Behavior Analysis (ABA) therapy. In Pennsylvania, state law (Act 62) requires many commercial health insurance plans to cover autism treatments, including ABA therapy, up to age 21 or 26, depending on the plan. However, denials still happen for various reasons. An appeal is your legal right to challenge that decision and fight for the therapy your child needs.
This process can feel overwhelming, but you do not have to go through it alone. Services like Trusted ABA Therapy can help connect you with vetted BCBA-led providers who understand the appeals process and can support you. This guide walks you through the steps, common pitfalls, and tips for success.

Why Are Autism Claims Denied in Pennsylvania?
Understanding why a claim is denied is the first step in crafting a successful appeal. Common reasons include:
- Not medically necessary: The insurer claims the therapy is not needed or that another treatment is more appropriate.
- Out-of-network provider: The ABA provider is not in your insurance company's network, so coverage is limited or excluded.
- Lack of preauthorization: The plan requires prior approval for ABA therapy, and you did not obtain it before starting services.
- Age limits: Your child has exceeded the covered age under the plan (usually 21 or 26 for state-regulated plans).
- Experimental or investigational: The insurer labels ABA therapy as experimental, though this is less common in Pennsylvania due to Act 62.
- Diagnosis or provider requirements not met: The denial may state that the therapist is not a BCBA or that the autism diagnosis was not made by a qualified professional.
Read the denial letter carefully. It must explain the specific reason, which is required by Pennsylvania law. If the letter is unclear, call the insurance company's customer service number and ask for a clear explanation in writing.
Step-by-Step Appeal Process for Pennsylvania Families
Step 1: Review the Denial Letter and Note the Deadline
Your denial letter will include a date by which you must file an appeal. For most commercial insurance plans in Pennsylvania, you have 180 days from the date of the denial letter to submit your appeal. For HealthChoices (Pennsylvania's Medicaid program), the deadline is usually 120 days. Mark this date on your calendar and set a reminder two weeks before to ensure you do not miss it. Missing the deadline means you may have to start from scratch or lose coverage permanently.
Step 2: Gather Supporting Documents
To build a strong appeal, you need evidence that supports medical necessity. Collect these documents:
- A copy of the denial letter (keep the original).
- A letter of medical necessity from your child's doctor or BCBA. This letter should explain why ABA therapy is medically necessary, what specific goals it addresses, and what the consequences of denial would be (e.g., regression in skills).
- A comprehensive diagnostic evaluation confirming an autism spectrum disorder diagnosis from a qualified professional (e.g., developmental pediatrician, child psychologist, or BCBA).
- A prescription or referral for ABA therapy from a physician.
- Progress reports or treatment plans from your ABA provider showing past progress and current goals.
- Your insurance policy or certificate of coverage to reference specific language about autism benefits.
- Any supporting research or clinical guidelines that confirm ABA as evidence-based (e.g., the American Academy of Pediatrics or U.S. Surgeon General).
Do not rely solely on verbal communication. Written evidence is critical.
Step 3: Write and Submit Your Appeal Letter
Draft a formal appeal letter. Include your name, your child's name, policy number, claim number, and the date of the denial. State clearly that you are exercising your right to appeal under Pennsylvania law. Attach all supporting documents and keep copies for your records. Send the appeal via certified mail with a return receipt to the address listed in the denial letter. This provides proof that the insurer received it. Most insurers also accept appeals through their online portal, but sending a physical copy ensures a paper trail.
If you lack a BCBA provider, consider using a service like Trusted ABA Therapy to get matched with vetted, BCBA-led providers who can help write a medical necessity letter and guide you through the process.
Step 4: Wait for the Internal Appeal Decision
After submitting your appeal, the insurer has a limited time to respond. For urgent appeals (e.g., if a delay could harm your child's health), they must respond within 72 hours under Pennsylvania law. For standard appeals, they have 30 days for commercial plans and 60 days for HealthChoices. If they approve, coverage begins. If they deny, you can move to the next step.
Step 5: Request an External Review
If the internal appeal is denied, you have the right to an independent external review. For commercial plans regulated by Pennsylvania, request an external review within 60 days of the internal denial. Send this request to the Pennsylvania Insurance Department's Consumer Services Bureau. They will assign an independent reviewer (not employed by the insurer) who will examine your case and make a binding decision. For HealthChoices, request a fair hearing through the Bureau of Hearings and Appeals within 120 days of the denial.
To request an external review for commercial insurance, you can call the Pennsylvania Insurance Department at 1-877-881-6388 (toll-free) or visit their website for forms. Keep detailed notes of all communications.
Step 6: Seek Legal or Professional Help if Needed
If the external review is also denied, consider consulting an attorney who specializes in insurance law or autism rights. Some states offer free legal aid through programs like Pennsylvania Legal Aid Network. Alternatively, your ABA provider's billing department may have experience with appeals. Many BCBA-led organizations, including those that partner with Trusted ABA Therapy, have case managers or supervisors who can advocate directly with insurers.

Common Mistakes to Avoid During the Appeals Process
- Missing deadlines: Always note the appeal deadline from the denial letter and file before it expires.
- Not keeping copies: Always keep a copy of every document you send and a log of phone calls, including dates, names, and what was discussed.
- Relying only on phone conversations: Verbal promises are not enough. Get everything in writing.
- Giving up too early: Many denials are reversed on appeal. About 40% to 60% of external reviews result in overturning the denial.
- Not using professional support: A BCBA or a provider experienced with appeals can greatly strengthen your case.
Costs, Insurance, and Financial Help
Under Pennsylvania's Act 62, most commercial health insurance plans (including those from large employers) are required to cover up to $36,000 per year of autism therapy for children aged 21 and under, though this cap may vary by plan. This law does not apply to self-funded plans (often from large employers), but many such plans voluntarily cover ABA. Medicaid (HealthChoices) also covers ABA therapy without an annual cap, though preauthorization is often required. If you face financial hardship, check with community nonprofits like Autism Speaks or The Autism Cares Foundation for potential grants or assistance.
If you are looking for providers who accept your insurance or Medicaid, Trusted ABA Therapy can match you with vetted BCBA-led providers in Pennsylvania who can help navigate these benefits.
