What Are Arizona Medicaid Waivers for Autism?
Arizona Medicaid waivers are special programs that allow the state to use federal Medicaid funds to provide home- and community-based services for individuals with disabilities, including autism. These waivers help families access therapies like Applied Behavior Analysis (ABA) without the high out-of-pocket costs. The two main waivers relevant to autism are the Arizona Long Term Care System (ALTCS) and the Division of Developmental Disabilities (DDD) waiver.

Who Is Eligible for These Waivers?
Eligibility for Arizona Medicaid waivers typically requires a formal diagnosis of autism spectrum disorder (ASD) from a qualified professional, such as a developmental pediatrician or psychologist. You must also meet income and resource limits, which vary by waiver. For the DDD waiver, individuals must have a developmental disability that began before age 22, while ALTCS focuses on those with significant functional needs. Children under 21 may qualify through the Arizona Health Care Cost Containment System (AHCCCS) with a medical necessity determination.
How to Apply
To apply, contact the Arizona Department of Economic Security (DES) or your local DDD office. You will need to provide diagnostic reports, medical records, and financial information. The process can take several months, so start early. Our free service can help you find providers who accept these waivers once approved.
What Services Do These Waivers Cover?
Arizona Medicaid waivers can cover a range of autism services, including:
- Applied Behavior Analysis (ABA) therapy, including assessment and treatment plans
- Speech and language therapy
- Occupational therapy
- Behavioral health services
- Respite care for caregivers
- Case management and coordination
ABA therapy is often a key service, as it is evidence-based for improving communication, social skills, and behavior. Coverage may require prior authorization and a treatment plan from a Board Certified Behavior Analyst (BCBA).

Costs and Insurance Considerations
With an approved waiver, families typically pay little to no out-of-pocket costs for covered services. However, there may be copays or deductibles depending on your specific plan. Arizona Medicaid (AHCCCS) also covers ABA therapy for children under 21 through the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit, even without a waiver. Always verify coverage with your provider and the waiver program.
Common Mistakes to Avoid
- Not applying early: Waitlists can be long, so start the process as soon as you have a diagnosis.
- Assuming all providers accept Medicaid: Many ABA providers are in-network, but always confirm. Our matching service can help you find vetted, BCBA-led providers who accept Arizona Medicaid.
