How do State-regulated Insurance Plans Cover Autism Therapy?

State-regulated insurance plans cover autism therapy through autism insurance mandates. These are state laws that require health insurance companies to provide coverage for the diagnosis and treatment of autism spectrum disorder, specifically including evidence-based treatments like Applied Behavior Analysis (ABA) therapy.

While these mandates provide a foundation for coverage, the specific details vary significantly depending on the state. Common ways these plans regulate and provide coverage include:

• Age Limits: Coverage is often restricted based on the child’s age. For example, Arizona covers ABA therapy up to age 16, Maryland provides protections up to age 21, and Utah has a limited mandate covering children up to age 9.
• Medical Necessity: To unlock benefits, families must demonstrate medical necessity. This requires documentation from a licensed professional, such as a diagnostic evaluation and an individualized treatment plan that outlines how therapy will address functional impairments.
• Service Restrictions: Plans may include benefit limits, visit caps, or annual spending maximums. They also typically distinguish between in-network and out-of-network provider costs.
• Prior Authorization: Most state-regulated plans require approval from the insurance provider before services can begin.

It is important to note that these state mandates only apply to fully insured plans. Self-funded (ERISA) plans, often provided by large employers, are regulated by federal law and are exempt from these state-level requirements. Coverage is always subject to verification and is not guaranteed.
