ABA therapy in Washington
Washington Medicaid covers ABA for eligible kids, and the state has required private insurance to cover autism care since 2014. Here’s how it actually works — and how we handle the messy parts for you.
Does Medicaid cover ABA in Washington? Yes.
THE COVERAGE PATHWAY
Apple Health (Medicaid) ABA benefit: eligibility requires a comprehensive evaluation and ABA order from a recognized Center of Excellence (COE) provider; services delivered through Apple Health managed-care organizations or fee-for-service
WHO RUNS IT
Washington State Health Care Authority (HCA); hca.wa.gov Apple Health
You don’t have to memorize any of this — we work with Washington’s system every day.
Getting approved, in three steps
Washington requires paperwork before therapy is covered. Here’s the whole process from your side of the table — we do the rest.
1
Round up the diagnosis paperwork
An autism diagnosis from a qualified provider is the key that opens coverage. Already have it? You’re ahead. If not, we’ll help you find an evaluation.
2
We build and submit the plan
Your BCBA assesses your child and writes the treatment plan. Then we file it with the right reviewer in Washington — forms, follow-ups, and all.
3
Coverage confirmed. Therapy starts.
Once the plan signs off, sessions begin. Most families who qualify start within 2–3 weeks. Approvals renew on a schedule — we track it so you never think about it.
The fine print, if you want it (Washington’s exact rules)
ABA provider must obtain prior authorization from HCA or the member's MCO before treatment, submitting the COE comprehensive evaluation/order plus the assessment and treatment plan; authorizations granted in 3-6-month increments with recertification by the lead behavior analysis therapist
Coverage details in Washington
How many hours a week?
Individualized per COE order and treatment plan; no fixed cap (ABA day program for under-6s typically 12-15 hours a week group)
Private insurance has to help too
Not on Medicaid? Washington’s autism insurance law makes state-regulated private plans cover autism care — you’d pay your plan’s normal deductible and copays. The rule on the books: 2014 - coverage required under Washington's Mental Health Parity Act following the WA Supreme Court O.S.T. v. Regence ruling and an Insurance Commissioner order (SB 5059 also cited); no age, dollar, or visit caps
Waiver programs worth knowing
Waivers can add services or open Medicaid eligibility even when family income is too high. In Washington: DDA HCBS waivers: Basic Plus, Core, Individual and Family Services (IFS), Children's Intensive In-Home Behavioral Supports (CIIBS), Community Protection
What does ABA actually cost in Washington?
Washington Medicaid reimburses ABA providers roughly $50 per hour for one-on-one therapy (rates differ by clinician credential and setting). That's what the state pays us — with Medicaid, most families pay nothing out of pocket.
Choosing a provider
How to find an ABA therapist in Washington
Searching for an ABA therapist in Washington — or for autism therapy in Washington, or autism services in Washington, which turn up much the same list — gives you two different kinds of result: directories that list anyone who paid to be listed, and providers who can tell you what is actually open for your address. The questions below separate them. They work on us as well as on anyone else — if we can’t answer one, that is worth knowing before you enroll.
In-home ABA therapy in Washington
Most ABA services in Washington are delivered where the child already is — at home, in a classroom or daycare room, and over video for parent coaching. That is the model we run. Ask any provider which settings they can actually staff near you, not which ones appear on their website. Coverage is a staffing question, and the honest answer changes week to week.
What a BCBA in Washington actually does
A BCBA — Board Certified Behavior Analyst — assesses your child, writes the treatment plan, sets the goals, and supervises the technicians who run the sessions. You should know the name of the BCBA in Washington assigned to your case, how often they observe sessions in person, and how many cases they carry. You can verify any certificant yourself in the BACB registry.
Autism testing in Washington
ABA is not the same appointment as a diagnosis. Autism testing in Washington is done by a developmental pediatrician, child psychologist or child neurologist, and most health plans want that evaluation on file before they will authorize therapy. An autism evaluation in Washington is a separate booking from therapy, with its own waitlist, so it is worth starting now rather than after you have chosen a provider. If your child is under three, early intervention autism services in Washington will evaluate for free, without a diagnosis or a referral. If you are still at that stage, start with how to find a diagnostician and what an autism evaluation involves. You do not need us to get one.
What “best ABA therapy in Washington” should mean
There is no ranking body, so nobody can honestly call themselves the best ABA provider in Washington. What you can compare is specific: how quickly a BCBA does the first assessment, whether goals are written for your family’s actual routines, how much supervision each technician gets, whether you are told about turnover before a new face arrives, and whether the provider will put a realistic start date in writing. Those are answerable questions. “Best” is not.
Five questions to ask any ABA provider in Washington
- 1. Who is the BCBA on my case, and how many hours a month will they spend supervising my child’s sessions?
- 2. What is your realistic start date for my address — not your average across Washington?
- 3. Which settings can you staff for us: home, school, daycare, telehealth?
- 4. What happens to my child’s schedule when a technician leaves?
- 5. What will I owe after insurance, and when will you tell me if that changes?
