Autism / ABA Therapy Insurance Denied in Texas? Here's How to Fight Back

Texas families fighting ABA therapy denials face a complex landscape — a strong state insurance mandate, a Medicaid managed care system, and insurers who routinely use internal criteria to limit or eliminate coverage. Here is exactly what you need to know to fight back.

Texas's Autism Insurance Mandate: HB 1897

House Bill 1897, effective September 2007 and strengthened over subsequent years, requires Texas insurers to cover ABA therapy for individuals with autism spectrum disorder (ASD). The mandate applies to fully insured plans regulated by the Texas Department of Insurance (TDI). Coverage is required for individuals diagnosed with ASD with no stated age limit in the statute, though plan-specific restrictions may apply.

Key details: The mandate requires coverage of "evidence-based, structured behavioral intervention" including ABA. There is no statutory dollar cap, but plans may impose limits if they apply the same limits to comparable mental health services (parity requirements apply). Self-funded ERISA plans are not bound by HB 1897.

Common ABA Denial Tactics in Texas

"Not medically necessary": Insurers rely on internal medical necessity criteria that differ from the ABA clinical guidelines published by the Behavior Analyst Certification Board (BACB) and AAP. Requests for high-intensity ABA (20–40 hours/week) for young children are frequently reduced to 10 hours or fewer.

Hour caps: Some Texas plans impose annual or weekly hour limits despite no such cap in the state mandate. These caps must be evaluated under mental health parity (MHPAEA).

Age cutoffs: A handful of plans attempt to cut off coverage at age 10 or puberty, citing lack of "evidence of continued benefit." This is a reviewable denial.

Supervisor ratio denials: Texas insurers sometimes deny claims when the BCBA-to-RBT ratio exceeds a policy threshold, claiming the supervision level is "not medically necessary."

"Educational not medical": Insurers argue that ABA is a school service. Texas law and federal mental health parity law do not support this exclusion for medically prescribed ABA.

How to Appeal an ABA Denial in Texas

Step 1 — Get the denial in writing. Texas requires insurers to issue written denial notices with the specific clinical criteria used. Request a copy of the clinical coverage policy.

Step 2 — Build your clinical file. Collect the ADOS-2 or CARS-2 diagnostic evaluation, the BCBA's individualized treatment plan with measurable goals, session data demonstrating progress, and a physician letter of medical necessity.

Step 3 — File an internal appeal. Send your appeal package to the insurer. Cite HB 1897, MHPAEA parity requirements, and the BACB Practice Guidelines. Insurers must respond within 30 days (standard) or 72 hours (urgent).

Step 4 — Request an IROs) Explained" class="auto-link">Independent Review Organization (IRO) review. Texas requires insurers to inform you of your right to an independent review after a denial. File with TDI's IRO program. The review is conducted by independent clinicians, and the decision is binding. File at tdi.texas.gov or call 1-800-252-3439.

Step 5 — File a TDI complaint. Simultaneously file a complaint with TDI, which investigates insurer compliance with HB 1897.

Texas Medicaid ABA: STAR Kids

Children under 21 with ASD who qualify for Medicaid may access ABA through the STAR Kids program, Texas's managed care program for children with disabilities. STAR Kids covers ABA as a medically necessary service through contracted managed care organizations (MCOs).

Enrollment: Apply through the Texas Health and Human Services Commission (HHSC) at hhs.texas.gov. Your child must have an ASD diagnosis and meet Medicaid income/categorical eligibility.

For children who need waiver services, the Texas Home Living (TxHmL) waiver and the Home and Community-based Services (HCS) waiver offer additional developmental disability supports, though waitlists can be long. Apply early.
