Delaware Medicaid: Comprehensive Coverage for Autism Treatment

What is the Diamond State Health Plan?

Delaware's Medicaid program is known as the Diamond State Health Plan. For qualifying families, it covers a wide range of medically necessary autism services, including Applied Behavior Analysis (ABA) therapy for children under age 21. Children enrolled in Medicaid also have access to speech therapy, occupational therapy, mental health counseling, and medication management.

How to Apply for Delaware Medicaid

Applications are handled through the Division of Social Services (State of Delaware). You can apply online via Delaware's assistance portal, by phone, or at your local DSS office. Eligibility is based on income and household size. Children who qualify for SSI (Supplemental Security Income) are automatically eligible. Once enrolled, families pay no or very low copays for most services.

Medicaid and ABA Therapy

ABA therapy is a core benefit for children with an autism diagnosis on the Diamond State Health Plan. Providers must be licensed and supervised by a Board Certified Behavior Analyst (BCBA). Our free matching service can help you find BCBA-led ABA providers in Delaware who accept Medicaid and have availability for new clients.

Early Intervention: Delaware's Birth to Three Program

Free Evaluations and Services for Infants and Toddlers

If you have concerns about your child's development before their third birthday, Delaware's Birth to Three program offers free developmental evaluations. If your child qualifies (typically a 25% or more delay in one or more areas), services such as ABA, speech, physical, and occupational therapy are provided at no cost to families. This is a federally mandated program under IDEA Part C.

How to Refer Your Child

You can make a referral by calling (302) 744-2500 or visiting the Delaware Birth to Three website. A service coordinator will guide you through evaluation and service planning. Services are typically provided in your home, at daycare, or in other natural settings. No income limit applies-the program is free for all eligible children.

Division of Developmental Disabilities Services (DDDS)

Ongoing Support for Individuals with Autism

The Division of Developmental Disabilities Services (DDDS), part of Delaware's Department of Health and Social Services, provides long-term supports for individuals with intellectual and developmental disabilities (including autism). Services include case management, respite care, day programs, employment support, and residential options. To access DDDS, you must apply for eligibility and be added to a waiting list. Some services are free, others may have sliding-scale fees based on income.

How to Apply for DDDS

Contact DDDS at (302) 744-9600 to request an eligibility determination. You will need documentation of the autism diagnosis and functional assessments. Once eligible, a case manager can help you navigate available programs.

School-Based Services: Free Through Special Education

Overview of IEPs in Delaware

Under the Individuals with Disabilities Education Act (IDEA), children with autism who require special education receive a free appropriate public education (FAPE) through an Individualized Education Program (IEP). This includes related services such as ABA (if determined necessary), speech-language therapy, occupational therapy, and social skills training-all at no cost to families. Delaware's school districts also offer early childhood special education programs for children ages 3-5.

Requesting an Evaluation

If you suspect your child needs special education services, write a letter to your school district's special education director requesting a comprehensive evaluation. The district must respond within a specific timeline (typically 60 days). You can also request an independent educational evaluation (IEE) at public expense if you disagree with the district's evaluation.

How Insurance Covers Autism Services in Delaware

Private Insurance and the Delaware Autism Mandate

Delaware law (Title 18, Chapter 33) requires most private health insurance plans to cover ABA therapy and other medically necessary autism treatments for children under age 21. This includes individual and small group plans, as well as state employee plans. Coverage limits may apply, but many plans have yearly caps. Always check your plan's benefit summary. If you have questions, contact the Delaware Insurance Commissioner's Office for assistance.

Practical Tips to Save on Autism Services

  • Apply for SSI immediately if your child has significant functional limitations. SSI often provides cash benefits and automatic Medicaid eligibility.
  • Use your child's IEP to request school-based ABA, speech, and OT-these are free and must be delivered by qualified providers.
  • Ask about sliding-scale fees at private clinics; some offer reduced rates for uninsured or underinsured families.
  • Join parent support groups through Autism Delaware or Facebook; members often share info about grants or low-cost providers.
  • Check for grant opportunities from organizations like the Autism Care Today (ACT) or local foundations.
  • Utilize our free matching service to quickly compare providers that fit your budget and location.

Common Mistakes to Avoid

  • Waiting too long to apply for state programs. Medicaid and DDDS have processing times; start the paperwork early.
  • Assuming you must pay for everything out-of-pocket. Many families miss out on free school services or insurance-covered ABA because they don't ask.
  • Not appealing a denial. If your insurance or school district denies a service, you have the right to appeal. The Parent Information Center can help.
  • Forgetting to reapply annually. Medicaid and DDDS require yearly renewals; missing a deadline can disrupt services.
  • Neglecting to use our free matching service. We do the legwork to find providers with immediate openings in your area-no cost, no obligation.
