What Washington Apple Health Covers for ABA Therapy
Apple Health covers ABA therapy as a medically necessary treatment for autism. This coverage includes:
- Comprehensive diagnostic evaluation: To determine medical necessity, usually conducted by a psychologist or developmental pediatrician.
- Behavioral assessment: A BCBA creates an individualized treatment plan after a functional behavior assessment.
- Direct therapy: One-on-one sessions with a registered behavior technician (RBT) under BCBA supervision.
- Parent training: Teaching caregivers strategies to support their child's progress at home.
- Treatment plan updates: Regular reviews and adjustments by the supervising BCBA.
Eligibility Requirements
To be eligible for ABA coverage through Apple Health, your child must be under 21 years of age, have a formal diagnosis of autism spectrum disorder, and receive a prescription from a qualified healthcare provider (e.g., a physician, psychiatrist, or psychologist). The therapy must be deemed medically necessary, meaning it targets deficits that significantly impair daily functioning.
How to Get a Referral
Start by scheduling an evaluation with a provider who can diagnose autism and write a prescription for ABA. Your child's primary care physician can often facilitate this. Once you have a diagnosis and prescription, you can contact our free matching service to find a BCBA-led provider in Washington who accepts Apple Health.
The Steps to Start ABA Therapy Through Apple Health
Here is a practical step-by-step process:
- Obtain a diagnosis: If your child does not already have an autism diagnosis, seek a comprehensive evaluation from a qualified professional.
- Get a prescription: Your doctor must write a prescription for ABA therapy, specifying the recommended hours per week (typically 10-40 hours depending on need).
- Choose a provider: Use our free service to find BCBA-led providers in your area who are enrolled with Apple Health.
- Submit a prior authorization: The provider will handle this with Apple Health. Approval usually takes 2-4 weeks.

Costs and Financial Considerations
Under Apple Health, families pay little to nothing out-of-pocket for covered ABA services. There are minimal copays for some services, but for most children, ABA therapy is provided at no cost. However, it is important to note that some services, such as those that are not medically necessary, may not be covered. Always confirm with your provider and insurer. Our matching service can also help you understand any specific plan details.
Common Mistakes to Avoid When Seeking Coverage
Navigating insurance can be tricky. Here are pitfalls to watch for:
- Not getting a proper diagnosis first: Without a formal autism diagnosis, coverage for ABA may be denied.
- Assuming all providers accept Apple Health: Not all ABA providers are enrolled. Our service only connects you with those who are.
- Delaying the process: Waitlists for evaluations and therapy can be long in Washington. Start as soon as you suspect your child needs support.
- Skipping prior authorization: Treatment without authorization may lead to denials. Providers usually handle this, but confirm it is in process.
