If you're looking for how to get an autism diagnosis in Arizona, the state routes developmental disability services through the Division of Developmental Disabilities (DDD), which operates under Arizona's Medicaid system (AHCCCS — the Arizona Health Care Cost Containment System). Arizona's insurance mandate and Medicaid coverage for ABA are both strong, and Phoenix has several solid diagnostic options.
How to Get an Autism Diagnosis in Arizona: Your First Steps
Start with your child's pediatrician. Bring written observations of specific concerns and request a referral to a developmental pediatrician or licensed psychologist for a comprehensive autism evaluation.
At the same time, contact the Arizona Early Intervention Program (AzEIP) if your child is under age 3. AzEIP evaluations are free and do not require a prior autism diagnosis. Call 1-888-439-5609 to start the intake process. Services begin within 30 days of the IFSP being signed.
For children age 3 and older, contact your local school district. Arizona districts must evaluate children suspected of having disabilities at no cost within 60 days of a written request.

Arizona Autism Insurance Mandate Arizona's autism insurance mandate (enacted 2008) requires state-regulated health insurance plans to cover the diagnosis and treatment of autism spectrum disorder, including ABA therapy. Coverage applies through age 25 under Arizona's mandate — one of the broader age ranges nationally. Self-funded employer ERISA plans may be exempt — check your plan documents.

What to Expect During an Autism Evaluation in Arizona
A comprehensive evaluation includes parent interview, cognitive testing, adaptive behavior assessment (Vineland-3), ADOS-2 and/or ADI-R, direct observation, and a written report (2–6 weeks after testing).
