Understanding Medicaid in Washington: Apple Health
Washington's Medicaid program is known as Apple Health. It provides free or low-cost health coverage to eligible residents, including children, families, pregnant individuals, and people with disabilities. Apple Health covers a wide range of medical services, and for families of autistic children, one of the most important benefits is coverage for applied behavior analysis (ABA) therapy.
ABA therapy is an evidence-based approach that helps individuals develop communication, social, and daily living skills while reducing challenging behaviors. Because autism is a medical diagnosis, Apple Health treats ABA as a medically necessary therapy for many children and youth.
If your child qualifies for Apple Health, you may be able to access ABA therapy with little to no out-of-pocket cost. The key is understanding eligibility requirements, the steps to get started, and how to find a provider who participates in the program.

Does Apple Health Cover ABA Therapy?
Yes, Apple Health covers ABA therapy for eligible members. Under the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit, states are required to cover medically necessary services for children under age 21. Washington has interpreted this to include ABA therapy for autism spectrum disorder when prescribed by a physician and provided by a qualified behavior analyst.
Coverage can include:
- Comprehensive diagnostic assessment by a BCBA
- Development of a treatment plan with measurable goals
- Direct one-on-one therapy in home, clinic, or community settings
- Parent and caregiver training
- Supervision and oversight by a BCBA
- Progress monitoring and periodic reassessment
There is no annual or lifetime dollar cap on ABA services under Apple Health for children who meet medical necessity criteria. However, services must be prior authorized, and the frequency and duration are determined based on individual need.
Who Is Eligible for ABA Coverage Through Apple Health?
Age Requirements
Apple Health covers ABA therapy for children and youth up to age 21. Coverage often begins as early as 18 months (when autism can be reliably diagnosed) and can continue through adolescence. For children under three, early intervention services may also be available through Washington's Infant Toddler Early Intervention Program (ITEP), but ABA is still a covered benefit under Apple Health.
Diagnosis and Medical Necessity
To qualify, your child must have a formal diagnosis of autism spectrum disorder (ASD) from a qualified professional, such as a developmental pediatrician, child psychiatrist, or licensed psychologist. Additionally, a physician must prescribe ABA therapy as medically necessary. The prescribing provider will typically need to submit documentation supporting the need for ABA, including how it addresses core deficits or challenging behaviors.
Medicaid Eligibility
Your family must meet Apple Health income and residency requirements. Many children in Washington qualify even if parents work; Apple Health covers kids in families earning up to 305% of the federal poverty level (about $80,000 for a family of three in 2025). Children in foster care or receiving SSI automatically qualify. You can apply through Washington Healthplanfinder or your local DSHS office.

How to Get ABA Therapy Through Apple Health: Step by Step
Step 1: Obtain an Autism Diagnosis
If your child does not yet have a formal diagnosis, start by seeking a comprehensive evaluation. Many developmental pediatricians, autism centers, and hospital-based clinics in cities like Seattle, Spokane, Tacoma, and Bellevue offer diagnostic assessments. Wait times can be several months, so consider calling multiple providers and asking about waitlist options.
Step 2: Get a Physician's Prescription for ABA
Once you have a diagnosis, ask your child's pediatrician or primary care provider to write a prescription for ABA therapy. The prescription should specify the diagnosis and recommended hours per week. Some providers may request a more detailed order, including goals and rationale.
Step 3: Find a BCBA-Led Provider That Accepts Apple Health
Not all ABA providers are enrolled with Apple Health. You'll need to find a clinic or agency that is a contracted provider. Our free matching service can help you locate vetted, BCBA-led therapy providers in your area that accept Apple Health. We work with clinics across Washington, from King County to Spokane County and beyond.
Step 4: Complete the Prior Authorization Process
Your chosen provider will submit a prior authorization request to Apple Health, including the diagnosis, treatment plan, and expected hours. Approval typically takes 2-4 weeks. Once authorized, you can begin therapy. Authorizations are usually for 6 months, after which a renewal is needed.
Step 5: Start Therapy and Track Progress
Once approved, therapy sessions can begin. A BCBA will lead the team, often working with registered behavior technicians (RBTs) who implement the plan. You'll receive regular progress reports and parent training to support your child's development at home.
What Specific ABA Services Are Covered?
Apple Health covers a comprehensive set of ABA services, but it's helpful to know exactly what you can expect. Covered services typically include:
- Assessment and treatment planning: A BCBA conducts a functional behavior assessment (FBA) or similar evaluation to create an individualized plan.
- Direct therapy: One-on-one sessions with a behavior technician under BCBA supervision, targeting communication, social skills, self-help, and reducing problem behaviors.
- Parent training: Structured sessions to teach caregivers strategies for supporting skills and managing behaviors.
- Supervision: The BCBA regularly observes sessions, adjusts the plan, and ensures quality.
- Care coordination: Communication with other providers (speech, OT, school) to align goals.
Not all providers offer all service delivery models (e.g., center-based vs. in-home). When using our matching service, you can specify your preferences and we'll connect you with providers that fit your needs and location.
Finding a Provider in Washington That Accepts Apple Health
Why Provider Matching Matters
While Apple Health covers ABA therapy, finding an available provider can be challenging. Many clinics have waitlists, especially in high-demand areas like Seattle and its suburbs. Some providers may only accept certain Medicaid managed care plans (e.g., Coordinated Care, Community Health Plan of Washington, Molina Healthcare).
Our free matching service simplifies the search. We maintain a network of vetted, BCBA-led providers across Washington state who accept Apple Health. You tell us your county, your child's age, and your preferences, and we'll identify providers with current openings. We handle the outreach so you don't have to call dozens of clinics.
Rural and Underserved Areas
If you live in eastern Washington, the Olympic Peninsula, or other rural areas, providers may be fewer. Telehealth ABA is sometimes an option for parent training or supervision. Our matching team can help you explore both in-person and remote possibilities.
Common Pitfalls to Avoid
- Delaying diagnosis: Without a formal ASD diagnosis, you cannot start the process. Begin seeking an evaluation as soon as you have concerns.
- Assuming any provider works: Not all ABA clinics are enrolled with Apple Health. Always verify before starting services.
- Missing prior authorization: Services started without authorization may not be paid. Let your provider handle this step.
- Ignoring managed care plan details: If you have an Apple Health managed care plan (most children do), ensure your provider is in-network with that specific plan.
- Not asking about parent training: Parent involvement is a key component of effective ABA. Check that your provider offers regular training sessions.
Additional Resources and Support
Washington offers several resources to support families navigating autism services:
- Washington State Department of Health Autism Guide: Information on diagnosis, services, and supports.
- Infant Toddler Early Intervention Program (ITEP): For children under three, offers evaluations and services (may complement ABA).
- Washington Autism Alliance: Provides advocacy, education, and referral assistance.
