Arizona Medicaid Autism Coverage
Arizona integrates DDD with ALTCS so eligible individuals with IDD generally avoid the multi-year waitlists common elsewhere. AHCCCS covers ABA through EPSDT for children under 21, and Steven's Law requires commercial plans to cover autism diagnosis and treatment.

AHCCCS covers ABA as medically necessary behavioral health treatment for children under 21 through their AHCCCS Complete Care (ACC) plan. DDD-enrolled members receive ABA through DDD-contracted health plans coordinated with long-term services.
