What Is a Washington DDA Waiver?

The Washington State DDA administers several Home and Community-Based Services (HCBS) waivers designed to help individuals with developmental disabilities live and thrive in their communities. Two of the most relevant waivers for funding ABA therapy are:

• Basic Waiver: Primarily for children and adults with developmental disabilities who need moderate support. It covers services like respite, personal care, and behavioral support, including ABA when authorized.
• Children's Intensive In-Home Behavioral Support (CIIBS) Waiver: For children (typically under 21) with significant behavioral challenges. This waiver specifically provides funding for intensive behavioral interventions, including ABA therapy, delivered in the home and community.

These waivers are part of the federal HCBS program, which allows states to use Medicaid funds to support community-based care instead of institutionalization. DDA waivers are not entitlement programs-enrollment is limited, and waitlists are common. However, once enrolled, the waiver can dramatically reduce or eliminate the cost of ABA therapy.

How DDA Waivers Fund ABA Therapy

ABA as a Covered Service

Under DDA waivers, behavioral support services are explicitly covered. This includes ABA therapy provided by a Board Certified Behavior Analyst (BCBA) and supervised behavior technicians (RBTs). The exact services authorized depend on the individual's needs, as determined by a DDA case manager and a comprehensive assessment. Common ABA services funded include:

• Initial functional behavior assessments (FBAs)
• Individualized behavior intervention plans (BIPs)
• One-on-one ABA sessions (often hours per week)
• Caregiver training and parent coaching
• Crisis intervention support (under CIIBS)

Funding is typically allocated in a monthly or annual budget based on assessed needs. Providers must be enrolled with DDA and Medicaid to bill for services.

Prior Authorization and Provider Networks

Before ABA therapy can begin under a DDA waiver, the service must be prior authorized by the individual's DDA case manager or a Medicaid managed care plan (if applicable). This means your BCBA provider will submit a treatment plan for approval. Not all ABA providers accept DDA waiver funding-finding one who does can be challenging. That's where Get ABA Therapy comes in: we match families with vetted, BCBA-led providers who are experienced with Washington DDA waivers.

Eligibility Requirements for DDA Waiver ABA Funding

To access ABA funding through a Washington DDA waiver, you must meet several criteria:

Developmental Disability Diagnosis

The individual must have a documented developmental disability that occurred before age 18, is likely to continue indefinitely, and results in substantial functional limitations. Autism spectrum disorder (ASD) qualifies, as do conditions like cerebral palsy, intellectual disability, and epilepsy.

Functional Need

You must demonstrate that the disability significantly impairs daily living activities such as communication, self-care, mobility, or social interaction. A DDA eligibility specialist will conduct an evaluation using state criteria.

Residency and Citizenship

The applicant must be a Washington State resident and a U.S. citizen or legal permanent resident.

Income and Asset Limits

DDA waivers are Medicaid-based, so financial eligibility applies. For the Basic Waiver, income must typically be within 300% of the federal Supplemental Security Income (SSI) limit (around $2,500/month in 2025), and assets under $2,000 for an individual. However, some waivers like CIIBS may have different thresholds. Spousal income and assets can be protected.

Many families mistakenly think they earn too much to qualify, but spend-down options or trust accounts can sometimes help. Always apply-the DDA will assess your financial situation.

How to Apply for a DDA Waiver for ABA Therapy

Step 1: Determine DDA Eligibility

Contact your local DDA Field Services office or call the DDA Intake line at (800) 562-5621 to request an eligibility evaluation. You will need to provide medical records, school records, and a diagnosis from a qualified professional (e.g., a developmental pediatrician or psychologist).

Step 2: Apply for a Specific Waiver

Once deemed eligible for DDA case management, you can ask to be placed on the waitlist for a waiver (Basic or CIIBS). Indicate that you are seeking funding for ABA therapy. The waitlist can be long-up to 2-3 years for the Basic Waiver, shorter for CIIBS in some counties.

Step 3: Develop a Person-Centered Plan

When you reach the top of the waitlist, a DDA case manager will work with you to create a person-centered service plan. This is where you advocate for ABA therapy as a needed service. Bring documentation from a BCBA showing medical necessity.

Step 4: Find a Provider and Obtain Authorization

With a waiver in hand, you then need to find a BCBA provider who accepts DDA funding. Get ABA Therapy can help you identify vetted providers in Washington who already work with DDA waivers. The provider will submit a treatment plan for prior authorization, and once approved, therapy can begin.

Costs and Insurance: What Families Should Know

ABA therapy is expensive-often $60-$150 per hour. With DDA waiver funding, the waiver covers the full cost of authorized services (no copay for most). However, you may still need to coordinate with private insurance if your waiver benefits are limited.

Many families use a blended approach: DDA waiver covers a set number of hours per week, and private insurance (or Medicaid Apple Health) covers additional hours. Washington State requires most private insurance plans to cover ABA for autism (per the Affordable Care Act and state mandates).

Be aware: DDA waivers have annual caps. The Basic Waiver might cover only 4-8 hours of behavioral support per week, while CIIBS can cover up to 40 hours. You can request a fair hearing if services are denied or reduced.

Practical Tips for Navigating DDA Waiver ABA Funding

• Start early: The waitlist can be years long. Apply for DDA eligibility as soon as your child is diagnosed, even if you don't plan to use the waiver immediately.
• Keep detailed records: Save all medical evaluations, school IEPs, and behavior reports. They strengthen your case for need.
• Advocate strongly: During the person-centered plan meeting, clearly explain why ABA is medically necessary. Bring a letter from a BCBA.
• Use a matching service: Get ABA Therapy is free and connects you with BCBA-led providers who already accept DDA waivers, saving you weeks of searching.
• Combine funding sources: If your waiver covers only partial hours, use it to supplement private insurance or Medicaid. Don't leave unused waiver funds on the table.
• Stay in touch with your case manager: Regularly update them on your child's progress and any changes in need. They can adjust authorized services.

Common Mistakes to Avoid

• Assuming you don't qualify: Many families with moderate incomes think DDA is only for low-income. Spouse income and assets are treated separately-apply anyway.
• Waiting until you need therapy: The waitlist is long; apply years before you anticipate needing ABA.
• Choosing a provider without DDA experience: Not all BCBAs know how to bill DDA waivers. Use a provider vetted by Get ABA Therapy.
• Failing to request a higher level of service: If your child's needs increase, ask for a reassessment and possibly a switch to CIIBS.
• Overlooking the fair hearing process: If services are denied, you have the right to appeal. Many families win on appeal.
