How long do I have to file an appeal after a denial in Texas?

For private insurance, you typically have at least 180 days from the date of the denial to file an internal appeal. For Texas Medicaid, the deadline is 90 days. Always check your denial letter for the exact deadline and act promptly.

Can I appeal a denial if my insurance says ABA is experimental?

Yes. ABA therapy is widely recognized as evidence-based by the U.S. Surgeon General and the American Academy of Pediatrics. In Texas, the autism insurance mandate generally prohibits plans from labeling ABA as experimental for autism treatment. Your appeal should include peer-reviewed studies and a letter from your BCBA.

What documents do I need for a successful appeal?

Key documents include the denial letter, a detailed letter from your BCBA explaining medical necessity, your child's diagnosis and treatment plan, session notes, and relevant research. Keeping a log of all communications with the insurer also helps.

Does Texas offer an external review if my internal appeal is denied?

Yes. Texas law allows you to request an independent external review through the Texas Department of Insurance. This review is free and binding on the insurer. You must request it within four months of the internal appeal denial.

Can Apply for ABA help me with insurance appeals?

Apply for ABA is a free matching service that connects you with vetted BCBA-led providers. While we do not directly handle appeals, many of our provider partners have experienced billing teams that assist families with insurance denials and appeals.

What if my insurance plan is self-funded (ERISA)?

Self-funded plans are not subject to Texas state insurance mandates, but they must follow federal ERISA law. You still have the right to appeal and request an external review. Contact the U.S. Department of Labor for guidance, and consider consulting a healthcare attorney.

In short: If your Texas health plan denies coverage for ABA therapy, you have the right to appeal. This playbook walks you through each stage-from internal appeals to external review-and explains how to use your state's protections to get the care your child needs.

Why Insurance Appeals Matter for ABA Therapy in Texas

When a health plan denies coverage for Applied Behavior Analysis (ABA) therapy, it can feel like a dead end. But in Texas, families have strong legal protections. The state's autism insurance mandate requires most private insurance plans to cover ABA therapy for children diagnosed with autism. Even so, denials happen-often due to paperwork issues, outdated medical necessity criteria, or miscommunication. Understanding the appeal process is your best tool to secure the therapy your child needs.

This guide is for Texas families. It covers the step-by-step appeal process, from reading your denial letter to requesting an external review. We'll also share practical tips and common mistakes to avoid. And remember, Apply for ABA is a free matching service that can help you find a vetted, BCBA-led provider-many of whom have experience navigating insurance appeals.

Understanding Your Rights Under Texas Law

The Texas Autism Insurance Mandate

Texas Insurance Code Chapter 1355 requires certain health benefit plans to cover autism spectrum disorder (ASD) treatments, including ABA therapy. This applies to large employer plans, HMOs, and some individual plans. Key points:

Coverage must include diagnosis, evaluation, and treatment of ASD.
ABA therapy must be prescribed by a licensed physician or psychologist.
Plans cannot deny coverage solely because the therapy is considered "educational" or "developmental."

However, the mandate does not apply to all plans-for example, self-funded employer plans (ERISA) may be exempt. Check your plan documents or call your insurer to confirm.

Medicaid and CHIP Coverage

Texas Medicaid (including STAR Kids and STAR Health) covers ABA therapy for eligible children under 21. The Texas Health and Human Services Commission (HHSC) oversees this coverage. Denials from Medicaid have their own appeal process, which we'll cover later.

Common Reasons ABA Claims Are Denied

Before you appeal, understand why your claim was denied. Common reasons include:

Lack of medical necessity - The insurer says the therapy isn't needed or doesn't meet their criteria.
Out-of-network provider - Your BCBA or clinic isn't in the plan's network.
Experimental or investigational - Some plans still classify ABA as "experimental," though this is rare in Texas.
Incomplete documentation - Missing diagnosis codes, treatment plans, or prior authorization.
Frequency or duration limits - The plan caps hours below what the provider recommends.

Your denial letter must state the specific reason. Keep this letter-you'll need it for your appeal.

Step-by-Step Appeal Process for Private Insurance

Step 1: Read Your Denial Letter Carefully

The denial letter includes the reason, the policy language they used, and the deadline to appeal. In Texas, you typically have at least 180 days from the date of the denial to file an internal appeal. Mark your calendar.

Step 2: Gather Supporting Documents

A strong appeal package includes:

A letter from your child's BCBA explaining medical necessity, goals, and progress.
Copies of the diagnosis (from a licensed professional) and any evaluations.
Peer-reviewed studies supporting ABA as an evidence-based treatment.
Your child's treatment plan and session notes.
Any prior correspondence with the insurer.

Your BCBA can often help write a detailed letter addressing the specific denial reason.

Step 3: File the Internal Appeal

Contact your insurance company's appeals department (the number is on your denial letter). Submit your written appeal and supporting documents. You can usually do this by mail, fax, or online portal. Keep copies of everything and get a confirmation receipt.

Texas law requires insurers to respond within 30 days for urgent appeals (if the delay could jeopardize your child's health) and 60 days for non-urgent appeals. If you don't hear back in time, you can escalate.

Step 4: If Denied Again - Request an External Review

If your internal appeal is denied (or not answered in time), you have the right to an independent external review. This is a second look by an outside organization not connected to your insurer. In Texas, the Texas Department of Insurance (TDI) oversees this process.

You must request the external review within four months of the internal appeal denial.
The review is free.
The external reviewer's decision is binding on the insurer.

To request an external review, contact TDI's Consumer Help Line at 1-800-252-3438 or visit their website. You'll need to fill out a form and submit your appeal file.

Appealing a Medicaid Denial

Medicaid denials follow a different path. If your child's ABA claim is denied through Texas Medicaid (STAR Kids, STAR Health, or traditional Medicaid):

You have 90 days from the denial notice to request a fair hearing with the Texas Health and Human Services Commission.
You can also file a state-level appeal with the managed care plan first (if applicable).
During the appeal, your child may be able to continue receiving services if you request "aid paid pending" within 10 days of the denial.

Contact HHSC's Office of the Ombudsman for help navigating Medicaid appeals.

Tips for a Successful Appeal

Work Closely with Your BCBA

Your BCBA is your strongest ally. They can write a clinical letter that directly counters the insurer's rationale. Many BCBAs have experience with appeals and know the language insurers want to see.

Use the Right Language

Avoid vague terms like "helpful" or "beneficial." Instead, use clinical language: "medically necessary," "evidence-based," "reduces maladaptive behaviors," "improves communication skills." Reference the Texas Autism Insurance Mandate if applicable.

Keep a Log

Document every phone call, including date, time, representative name, and what was discussed. Save emails and letters. This creates a paper trail in case you need to escalate further.

Don't Give Up

Many families succeed on appeal. Even if you're denied twice, you may have options like filing a complaint with TDI or consulting a healthcare attorney. Some nonprofit legal clinics in Texas offer free assistance for autism insurance denials.

Common Mistakes to Avoid

Missing deadlines - Mark your calendar the day you receive the denial.
Not including a provider letter - Insurers want clinical evidence, not just parent testimony.
Assuming a denial is final - Most denials can be overturned with a proper appeal.
Ignoring the external review option - This is a powerful tool that many families don't know about.
Not checking if your plan is self-funded - If it is, state mandates may not apply, but you still have federal protections under ERISA.
