SB 1590 Arizona Senate · 57th Legislature - First Regular Session

mental health; autism; insurance coverage

Arizona's SB 1590 requires health insurers to cover behavioral therapy for autism spectrum disorder (ASD) without excluding coverage based solely on an ASD diagnosis. It mandates coverage for medically necessary behavioral therapy services (provided by licensed professionals) with annual limits: $50,000 for children under nine and $25,000 for ages nine to sixteen. The law applies to group health plans but excludes individual plans, small employers, and out-of-state services. It does not eliminate cost-sharing like deductibles but ensures insurers cannot deny coverage for ASD-related treatment or therapy.
