Autism Evaluation in Texas: 2026 Guide

Frequently asked questions

How long is the autism evaluation waitlist in Texas?

Private autism evaluations in Texas typically take 4 to 12 months from referral to evaluation date. The state's Early Intervention program (Early Childhood Intervention (ECI)) is faster for children under 3, with evaluation completed within 45 days of referral by federal law.

Can the school evaluate my child for autism in Texas?

Yes, for children age 3 and up. Submit a written request (email is fine) to your campus special education coordinator, with a copy to the district's Director of Special Education. Texas Education Code requires the district to respond within 15 school days. Texas Education Code §29.004 (19 TAC §89.1011) sets a stricter timeline than federal: 45 school days from signed parental consent to completed Full Individual Evaluation (FIE), then 30 calendar days to convene the IEP meeting. A school eligibility determination of "Autism" qualifies the child for an IEP and special education services, but it is not the same as a medical diagnosis from a developmental pediatrician (which insurance and Medicaid waivers may require separately).

Who pays for autism evaluation in Texas?

Early Intervention (under 3) and school evaluations (3+) are free. Private evaluations: copay or coinsurance after deductible varies by plan; aba covered under tx insurance code §1355.015 (hb 451 (2007) as amended by sb 1484 (2013)); $1,500 to $4,500 for a full diagnostic battery; some clinics offer sliding-scale fees. TX Insurance Code §1355.015 requires state-regulated plans to cover diagnosis and treatment of autism including ABA from initial diagnosis through age 9. The statute provides that coverage may not be discontinued solely because the enrollee turns 10 and continues to need treatment. Plan-level deductibles, copays, and coinsurance apply consistent with §1355.015(d).

Do I need a referral from my pediatrician to start in Texas?

No, not for Early Childhood Intervention (ECI) (Early Intervention). You can self-refer directly using the program's referral page. For private clinics, some require a pediatrician's referral form for insurance billing; many do not. Always call the clinic to confirm before joining the waitlist, since being on the wrong list wastes months.

My child is on a long waitlist in Texas. What can I do right now?

Three things, in order. First, refer to Early Childhood Intervention (ECI) (under 3) or your school district (3+); these run on legal deadlines, not waitlists. Second, document what you see at home (videos, behavior patterns, sleep, sensory triggers) so the eventual evaluation has data to work with. Third, start no-diagnosis-required supports: visual schedules, sensory accommodations, predictable routines. Our free 30-day plan tool combines all three based on your specific situation in Texas.

What is the Texas autism insurance mandate?

TX Insurance Code §1355.015 requires state-regulated plans to cover diagnosis and treatment of autism including ABA from initial diagnosis through age 9. The statute provides that coverage may not be discontinued solely because the enrollee turns 10 and continues to need treatment. Plan-level deductibles, copays, and coinsurance apply consistent with §1355.015(d).

How long is the Texas Medicaid waiver waitlist for autism?

Typical wait from registry application to a funded slot in Texas is on the order of 13 years, based on published agency data. Children and adults with intellectual or developmental disabilities. Income limits apply, but the child's income is what's counted, not the parents' (deeming waiver). The interest list (~68,000 Texans) typically waits 10 to 15+ years. Apply on the date of diagnosis (or earlier if you have substantial functional impairment documentation), because your application date is what locks your place in line.
