Delaware - Autism Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-09

Delaware Health and Social Services (DHSS), through the Division of Medicaid and Medical Assistance (DMMA), covers Behavioral Interventions to Treat Autism Spectrum Disorder for Medicaid recipients under age 21 as a State Plan service, while the Division of Developmental Disabilities Services (DDDS) administers adult and waiver-based behavioral supports. The state utilizes a combination of Licensed Behavior Analysts (LBAs) and unlicensed technicians operating under strict supervisory frameworks to deliver Applied Behavior Analysis (ABA) and related interventions.

Agencies seeking to provide these services under the DDDS Lifespan Waiver must secure an award through the Division of Management Services (DMS) open Request for Proposals (RFP) process on the Bonfire Hub before a service contract is issued. Standard Medicaid EPSDT providers must complete credentialing through the Delaware Medical Assistance Portal (DMAP) and secure network contracts with the state's managed care organizations to receive reimbursement.

1. Service Definition and Scope

In Delaware, Behavioral Interventions to Treat Autism Spectrum Disorder encompass medical and remedial care services, primarily Applied Behavior Analysis (ABA), designed to improve cognitive, behavioral, and social functioning. These services are covered under the EPSDT benefit for children up to age 21 and through specific HCBS waivers for adults.

The service model requires a tiered approach where a licensed practitioner develops a Behavior Support Plan or ABA Treatment Plan, and unlicensed practitioners (such as Registered Behavior Technicians) implement the plan under direct, documented supervision.

2. Regulatory and Oversight Agencies

The Delaware Department of Health and Social Services (DHSS) is the umbrella agency overseeing Medicaid and developmental disability services. Within DHSS, the Division of Medicaid and Medical Assistance (DMMA) manages the Medicaid State Plan and MCO contracts, while the Division of Developmental Disabilities Services (DDDS) oversees HCBS waiver providers.

Professional licensure for behavior analysts is managed by the Division of Professional Regulation (DPR) under the Board of Mental Health and Chemical Dependency Professionals. Provider enrollment and claims processing are handled by Gainwell Technologies through the Delaware Medical Assistance Portal (DMAP).

3. Gatekeeping Prerequisites: Who Can Even Apply

Providers seeking to serve the DDDS waiver population face a strict procurement gate: they must submit a proposal to the open and continuous Request for Proposals (RFP) titled 'Home and Community Based Services for Individuals with Intellectual and Developmental Disabilities' via the Bonfire Hub. The Division of Management Services Procurement Office must accept the bid, and DDDS must award the RFP before any service contract is issued.

For EPSDT ABA services under the State Plan, providers must successfully enroll in the DMAP system and subsequently secure network contracts with Delaware's Medicaid Managed Care Organizations (MCOs). Without MCO affiliation, providers cannot bill for the majority of Medicaid-enrolled children in the state.

4. Licensure and Certification Requirements

Delaware requires the lead practitioner designing and supervising the ABA program to be a Licensed Behavior Analyst (LBA). This license is issued by the Delaware Board of Mental Health and Chemical Dependency Professionals. Applicants must hold current certification from the Behavior Analyst Certification Board (BACB).

Agencies do not receive a distinct 'ABA Agency' license from the state; instead, they are approved as Medicaid providers based on the licensure of their clinical staff and compliance with DDDS Provider Standards or DMMA State Plan requirements.

5. Medicaid Provider Enrollment

All authorized providers must enroll through the Delaware Medical Assistance Portal (DMAP), operated by Gainwell Technologies. For DDDS providers, this occurs in Phase 3 of the approval process, requiring a Qualified Provider Authorization Letter issued by the Division.

The enrollment application requires submission of professional licensing, business information, and ownership disclosures. Providers must select the appropriate taxonomy codes for behavioral health and ABA services.

6. Staffing, Training and Background Checks

Delaware mandates strict supervisory ratios and oversight protocols for ABA services. Unlicensed practitioners must operate under the direct supervision of a licensed practitioner who is responsible for the work methods and regularly reviews the work performed.

All staff providing direct services must pass comprehensive background checks, including Delaware State Police fingerprinting and child/adult abuse registry checks, prior to client contact.

7. Documentation, Policies and Records

Providers must maintain comprehensive clinical and administrative records. The cornerstone of ABA service delivery is the Behavior Support Plan or ABA Treatment Plan, which must be individualized, medically necessary, and updated at least every six months.

Supervisory relationships must be documented in writing. Session notes must include start and stop times, the specific interventions utilized, data collected on target behaviors, and the signature of the rendering provider.

8. Billing, Rates and Claims

Delaware DMMA establishes fee-for-service rates using the Resource Based Relative Value Scale (RBRVS) methodology, adopted from the Medicare Fee Schedule Data Base. When no RVU exists, rates are benchmarked against comparable states.

Claims for EPSDT services are typically submitted directly to the enrollee's MCO, while waiver claims may be processed through DMAP. Prior authorization is strictly enforced for intensive services, particularly those exceeding 40 hours per week.

9. Approval Sequence and Timeline

For DDDS waiver providers, the approval sequence is a rigid four-phase process: Phase 1 (Information Gathering), Phase 2 (Application and Authorized Provider Committee Interview), Phase 3 (Medicaid Enrollment and RFP Response), and Phase 4 (Contracting and Final Approval).

The timeline can extend several months. The DMS Procurement Office and DDDS review RFP proposals only once per quarter, creating built-in waiting periods. Initial Authorization from DDDS does not permit the agency to recruit or accept service recipients until Phase 4 is complete.

10. Common Denials and Survey Findings

DDDS strictly enforces application completeness; incomplete applications are not reviewed and are immediately returned. A common failure point is not submitting the Requirements Summary Checklist in Word format or failing to create separate .pdf documents for each question as mandated.

During post-enrollment audits, common survey findings include inadequate documentation of the supervisory relationship between LBAs and technicians, and failure to secure prior authorization for hours exceeding the approved Treatment Plan.

11. Key Contacts and Resources

Prospective providers should utilize the DDDS Provider Application Manual and the DMAP portal for primary guidance. The DDDS Authorized Provider Committee maintains a dedicated resource mailbox for application-specific inquiries.

For Medicaid enrollment technical assistance, Gainwell Technologies operates a provider call center. MCO contracting requires direct outreach to the respective health plans' provider relations departments.
