What Is CT DDS and How Does It Support Adults with Autism?

The Connecticut Department of Developmental Services (DDS) is a state agency that provides supports and services for individuals with developmental disabilities, including autism spectrum disorder. For adults on the autism spectrum, DDS can be a vital resource for accessing applied behavior analysis (ABA) therapy and other behavioral health services. DDS funds these services through federally approved Medicaid waivers, allowing eligible adults to receive care in community settings rather than institutions.

DDS recognizes that many adults with autism continue to benefit from ABA therapy to build life skills, improve communication, manage challenging behaviors, and increase independence. Because ABA therapy is evidence-based and highly individualized, DDS supports its use across the lifespan when appropriate. The agency works with individuals and families to develop person-centered plans that include ABA as part of a comprehensive support network.

Trusted ABA Therapy is a free matching service that helps families connect with BCBA-led providers. While we do not provide therapy ourselves, we can assist in finding DDS-participating providers in Connecticut.

Eligibility for DDS-Funded ABA Therapy for Adults

Who Qualifies for DDS Services?

To receive DDS-funded ABA therapy, an adult must first be determined eligible for DDS services. The eligibility criteria include:

  • A documented developmental disability, such as autism spectrum disorder, that began before age 22.
  • Significant functional limitations in at least three major life activities (e.g., self-care, communication, learning, mobility, self-direction, independent living).
  • A need for ongoing support that is likely to continue indefinitely.

Diagnosis alone does not guarantee eligibility. DDS conducts a comprehensive evaluation to assess functional needs. Adults who were already receiving DDS services as children may continue seamlessly, while others may need to apply for the first time.

How to Apply for DDS Eligibility

Applying for DDS involves submitting an application and supporting documentation (diagnosis, functional assessments, medical records) through the DDS regional office. A case manager will be assigned to guide you through the process. DDS also offers a "Request for Eligibility Determination" form on its website. After approval, the case manager will help develop a Person-Centered Plan (PCP) and identify appropriate waivers and services.

Understanding DDS Waivers for ABA Therapy

Home and Community-Based Services (HCBS) Waivers

DDS operates several HCBS waivers funded by Medicaid that can cover ABA therapy for adults. The most common are the Comprehensive Waiver and the Employment and Day Services Waiver. These waivers allow DDS to pay for services like behavioral consultation, behavior management, skills training, and ABA therapy provided by Board Certified Behavior Analysts (BCBAs) and supervised behavior technicians.

Services are tailored to the individual's goals, which may include developing daily living skills, reducing interfering behaviors, improving social communication, and increasing community participation. The amount and frequency of ABA therapy depend on the waiver tier and the person's needs as documented in the PCP.

Does DDS Cover 1:1 ABA Therapy for Adults?

Yes, DDS waivers can fund 1:1 ABA therapy for adults when clinically indicated, though the level of intensity may differ from early childhood programs. For adults, ABA often focuses on functional routines, vocational skills, and self-advocacy. Services are provided by BCBAs and Registered Behavior Technicians (RBTs) under supervision. DDS requires that all providers meet state qualifications and be enrolled as Medicaid providers.

Costs, Insurance, and Coordination with Other Payers

Is ABA Therapy Free Through DDS?

For eligible adults enrolled in a DDS waiver, ABA therapy is covered at no direct cost to the individual. DDS pays the provider using Medicaid funds. However, adults may have other coverage through private insurance or HUSKY Health (Connecticut's Medicaid program). DDS typically serves as a payer of last resort, meaning other insurance is billed first if available.

Coordinating with HUSKY Health and Private Insurance

Many adults with autism have HUSKY Health or employer-sponsored insurance. In those cases, DDS will often coordinate with the primary insurer to avoid duplication of benefits. Some ABA providers may accept both DDS and private insurance, simplifying billing. It is important to verify coverage with your providers and DDS case manager. Our free matching service can help connect you with providers who accept multiple funding sources, reducing administrative burden.

Can You Use DDS Funding to Supplement Private Insurance?

Yes, if private insurance covers a limited number of ABA hours, DDS may fund additional hours to meet the individual's full needs. This requires prior authorization and a clear justification in the person-centered plan. Always communicate with your DDS case manager about other coverage.

How to Find a BCBA-Led ABA Provider That Accepts DDS

Choosing a Qualified Provider

Not all ABA providers accept DDS funding. It is essential to find a clinic or agency that is enrolled as a DDS provider and employs BCBAs with adult experience. Ask potential providers: "Do you accept DDS waivers for adults?" and "Can you work with my DDS case manager?"

Practical Tips for Navigating DDS and ABA for Adults

  • Start early: The eligibility and waiver enrollment process can take several months, so begin as soon as possible, even before you need services.
  • Build a strong case: Gather comprehensive documentation of your loved one's diagnosis and functional challenges to support eligibility.
  • Ask about self-direction: Some DDS waivers allow self-directed budgets, giving you more control over provider selection and hours.
  • Stay organized: Keep copies of all correspondence, plans, and provider agreements for reference.
  • Advocate for your needs: Be clear about the goals for ABA therapy-whether it is reducing behaviors, increasing communication, or building work skills.

Common Mistakes to Avoid

  • Waiting too long to apply: DDS has waitlists for some waivers; applying early reduces delays.
  • Assuming DDS covers everything: Not all ABA providers accept DDS, and not all waivers cover the same intensity. Verify coverage before starting therapy.
  • Ignoring insurance coordination: Failure to coordinate with private insurance can lead to billing conflicts or service interruptions.
  • Choosing a provider without adult experience: ABA for adults differs from children's therapy. Ensure the BCBA has relevant training and experience.
  • Not using free matching services: Our service saves time and helps you find DDS-participating, BCBA-led providers quickly.
