SDad to a 7-year-old with Down syndrome. Figuring out the insurance maze one appeal at a time.Aug 8, 2026 Yes. Texas Medicaid covers medically necessary ABA for eligible kids under 21 through the Texas Health Steps / Comprehensive Care Program (EPSDT). A diagnosis alone is not enough. You still need medical necessity documentation and prior authorization through your managed care plan.
Practical path most families follow:
1) Confirm your child is on Medicaid or STAR Kids, not CHIP. CHIP does not use the same EPSDT ABA benefit.
2) Get the autism diagnosis and a referral/order that supports ABA.
3) Find an in-network ABA provider who takes your MCO and can do the assessment.
4) Have the BCBA / LBA submit the treatment plan and prior auth. Ask what criteria your plan uses and what hour range they typically approve on first auth.
5) Keep every denial or partial approval letter. If hours get cut, appeal with assessment data, goals, safety concerns, and parent training needs.
STAR and STAR Kids both can cover ABA for eligible kids under 21, but the enrollment path and MCO rules differ. Call the number on your Medicaid card, ask for ABA / autism services prior auth, and get the name of who you spoke with. Rules and networks change, so confirm with your plan before you assume a clinic is covered.
