Who Is Eligible for Washington Medicaid Waivers?
Eligibility for Washington Medicaid waivers depends on several factors, including age, diagnosis, and functional need. Here's what you need to know:
Children Under 21
To qualify for the CIIBS waiver, a child must:
- Have a diagnosis of autism spectrum disorder (ASD) from a qualified professional.
- Be under 21 years old.
- Meet financial eligibility for Medicaid (income and asset limits apply).
- Demonstrate a need for intensive behavioral support, such as significant challenges with communication, social skills, or behavior.
Adults 21 and Older

- A diagnosis of a developmental disability (including autism) that began before age 22.
- Functional limitations in at least three areas of major life activity (e.g., self-care, learning, mobility).
- Financial eligibility for Medicaid.
It's important to note that waivers have limited slots, so there may be a waiting list. Contact your local Developmental Disabilities Administration (DDA) office to start the application process.
How to Apply for a Washington Medicaid Waiver
Applying for a waiver can feel overwhelming, but breaking it down into steps makes it manageable. Here's a general guide:
Step 1: Gather Documentation
You'll need:
- Your child's autism diagnosis (from a doctor, psychologist, or developmental pediatrician).
- Proof of income and assets (pay stubs, tax returns, bank statements).
- Medical records showing the need for behavioral support.
Step 2: Contact Your Local DDA Office
Washington State's DDA manages waiver applications. Find your local office online or call the DDA hotline at 1-800-562-3021. They'll guide you through the intake process and schedule an assessment.
Step 3: Complete the Assessment
A DDA case manager will evaluate your child's needs using tools like the Supports Intensity Scale (SIS). This assessment determines eligibility and the level of support required.

What Services Do Washington Medicaid Waivers Cover?
Washington Medicaid waivers cover a range of autism services, but the specifics depend on the waiver type. Here's what's typically included:
Applied Behavior Analysis (ABA) Therapy
ABA therapy is a core service under the CIIBS waiver. It's provided by Board Certified Behavior Analysts (BCBAs) and focuses on improving communication, social skills, and reducing challenging behaviors. The waiver covers up to $30,000 per year for these services.
Other Covered Services
- Respite care: Temporary relief for caregivers.
- Case management: Coordination of services and supports.
- Behavioral consultation: Guidance from a BCBA for families.
- Parent training: Education on implementing strategies at home.
- Transportation: Assistance getting to appointments.
For adults on the Core Connections waiver, services may include supported employment, day programs, and community inclusion supports.
Costs and Insurance: What You Need to Know
One of the biggest advantages of Washington Medicaid waivers is that they significantly reduce or eliminate out-of-pocket costs for eligible families. Here's a breakdown:
- No premiums or deductibles: Once enrolled in Medicaid, you typically pay nothing for covered services.
- Co-pays may apply: Some services may have small co-pays (e.g., $3 for a doctor visit), but these are capped.
- ABA therapy is fully covered: Under the CIIBS waiver, ABA therapy is covered up to the annual limit, with no additional charges.
It's important to note that waivers are not insurance; they are programs that pay for services not covered by standard Medicaid. However, you must be enrolled in Medicaid to qualify. If you're not sure about your eligibility, contact the Washington Health Benefit Exchange or your local DDA office.

Common Mistakes to Avoid When Applying
Navigating the waiver process can be tricky. Here are common pitfalls to watch out for:
- Missing documentation: Ensure you have a formal autism diagnosis from a qualified professional. A school evaluation may not suffice.
- Not applying early: Waiver slots are limited, so apply as soon as your child is diagnosed.
- Ignoring financial eligibility: Even if you think you earn too much, some waivers have income disregards. Check with a DDA case manager.
- Assuming all providers accept waivers: Not all ABA providers are enrolled with Medicaid. Our free service can connect you with vetted providers who do.
- Forgetting to renew: Waivers require annual renewal. Keep your contact info and documentation up to date.
