Delaware - Occupational Therapy Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-08-16

In Delaware, Occupational Therapy (OT) services within the Medicaid framework provide essential evaluation, treatment, and functional restoration for beneficiaries with physical, cognitive, or developmental disabilities. These services are authorized under the state's fee-for-service system, the Diamond State Health Plan (DSHP) 1115 Waiver, and Home and Community-Based Services (HCBS) waivers administered by the Division of Developmental Disabilities Services (DDDS).

The single biggest structural barrier to entry for new OT providers in Delaware is the strict sequential credentialing mandate. Providers cannot simply submit a Medicaid application; they must first secure a Delaware Board of Occupational Therapy Practice license, obtain Medicare PECOS approval (for therapy groups), successfully navigate the Delaware Medical Assistance Program (DMAP) portal, and finally secure network contracts with all three of Delaware's Medicaid Managed Care Organizations (MCOs) to access the majority of the patient population.

1. Service Definition and Scope

Occupational Therapy in Delaware Medicaid is defined as medically necessary evaluation and treatment designed to restore, improve, or maintain a beneficiary's ability to perform daily occupations. Services must be ordered by a physician and delivered by or under the supervision of a licensed Occupational Therapist.

Under Delaware's HCBS waivers, such as the DDDS Lifespan Waiver, OT services may also focus on habilitation and adapting the individual's environment to maximize independence in community settings.

• Service Scope: Includes comprehensive evaluation, therapeutic exercise, neuromuscular reeducation, sensory integration, and cognitive rehabilitation.
• Target Population: Medicaid beneficiaries and HCBS waiver participants with physical, cognitive, or developmental impairments requiring functional intervention.
• Waiver Authority: Covered under the Diamond State Health Plan (DSHP) 1115 Waiver and the DDDS Lifespan Waiver.
• Supervision Rules: Licensed Occupational Therapists may delegate and supervise treatments provided by licensed Occupational Therapy Assistants (OTAs) per state board regulations.
• Service Settings: Approved for delivery in outpatient clinics, patient homes, or community-based settings depending on the specific MCO authorization or waiver care plan.
• Exclusions: Services deemed strictly educational, vocational, or recreational without a direct medical or functional restoration goal are not covered.

2. Regulatory and Oversight Agencies

Oversight of Occupational Therapy in Delaware is divided between professional licensing boards and state health departments. The Division of Professional Regulation handles individual licensure, while the Division of Medicaid and Medical Assistance governs program rules and reimbursement.

For providers serving the intellectual and developmental disability population, the Division of Developmental Disabilities Services acts as the primary operating agency for HCBS waiver compliance.

• Delaware Division of Professional Regulation (DPR) - Board of Occupational Therapy Practice: Issues and renews professional licenses for OTs and OTAs (https://dpr.delaware.gov/boards/occupationaltherapy/).
• Delaware Division of Medicaid and Medical Assistance (DMMA): Administers the overarching Delaware Medical Assistance Program (DMAP) and sets Medicaid policy (https://dhss.delaware.gov/dmma/home/medicaid).
• Delaware Division of Developmental Disabilities Services (DDDS): Oversees HCBS waiver providers and manages the open enrollment process for waiver services (https://dhss.delaware.gov/ddds/homepage/providers).
• Delaware Medical Assistance Portal (DMAP): The official state MMIS portal used for provider enrollment, fee-for-service claims, and policy manuals (https://medicaid.dhss.delaware.gov/provider).
• Highmark Health Options: One of the three designated Managed Care Organizations (MCOs) administering the DSHP (https://www.highmarkhealthoptions.com/providers).
• AmeriHealth Caritas Delaware: A designated MCO for Delaware Medicaid members (https://www.amerihealthcaritasde.com/provider/).
• Delaware First Health: A designated MCO for Delaware Medicaid members (https://www.delawarefirsthealth.com/providers/become-a-provider.html).

3. Gatekeeping Prerequisites: Who Can Even Apply

Delaware does not require a Certificate of Need (CON) for independent occupational therapy practices, nor does it utilize closed procurement (RFP) windows for DDDS HCBS waiver therapy providers. The state accepts HCBS provider applications on an open and continuous basis.

However, strict structural prerequisites block DMAP enrollment until met. Applicants must hold active state licensure and, for therapy groups, federal Medicare approval before the state portal will accept their application.

• Professional Licensure Prerequisite: Applicants must hold an active, unrestricted Delaware OT or OTA license from the DPR before initiating any Medicaid enrollment steps.
• Medicare PECOS Mandate: Therapy groups and high-risk providers must be fully enrolled and approved in Medicare PECOS prior to applying to Delaware Medicaid.
• Open Enrollment Status: DDDS HCBS waiver applications are accepted on an open and continuous basis; there are no moratoria or closed networks blocking initial state enrollment.
• MCO Contracting Requirement: Because the vast majority of Delaware Medicaid members are enrolled in the DSHP managed care program, providers must successfully contract with all three MCOs to maintain a viable Medicaid practice.
• Physical Location Verification: Providers must have a verifiable physical service location in Delaware (or a border state if applicable) and an active NPI mapping exactly to the legal entity.
• Taxonomy Alignment: The provider's National Provider Identifier (NPI) taxonomy must strictly match the Delaware Medicaid provider type being requested.

4. Licensure and Certification Requirements

The Delaware Board of Occupational Therapy Practice governs the licensure of all OTs and OTAs in the state. Applications are processed entirely online through the DELPROS system.

Applicants must demonstrate educational competency, pass national board exams, and clear strict criminal background checks before a license is issued.

• Application Portal: All licensure applications must be submitted through DELPROS (Delaware Professional Regulation Online Services).
• Initial Licensing Fees: The application fee is $223 for an Occupational Therapist and $88 for an Occupational Therapy Assistant.
• Educational Transcripts: Applicants must have an official transcript sent directly from an ACOTE-accredited college or university to the Board office.
• Examination Scores: Proof of passing the NBCOT (National Board for Certification in Occupational Therapy) Certification Exam is required.
• Background Check: Mandatory state and federal criminal background checks via IdentoGO fingerprinting; applicants must obtain a Service Code from DELPROS to schedule.
• License Renewal: Licenses expire on July 31 of even-numbered years and require renewal through DELPROS.
• Continuing Education: Providers must complete 24 hours of approved Continuing Education Units (CEUs) every 2 years to maintain licensure.

5. Medicaid Provider Enrollment

Once licensed, providers must enroll in the Delaware Medical Assistance Program (DMAP) using the state's online provider portal. This step registers the provider with the state's MMIS.

The application requires a comprehensive dossier of business and tax documents. Upon submission, providers receive an Application Tracking Number (ATN) to monitor their status.

• Enrollment Portal: Applications must be submitted via the DMAP Provider Enrollment wizard (https://medicaid.dhss.delaware.gov/provider).
• Application Fee: Institutional providers (such as therapy clinics) must pay a $750 enrollment fee at initial application, revalidation, and when adding a new location.
• Tax Documentation: A signed IRS Form W-9 (dated within the last 12 months) and an IRS CP-575 or LTR 147C confirming the active EIN are required.
• Banking Verification: A voided check or bank letter matching the IRS Tax ID and legal entity name must be uploaded for EFT setup.
• Ownership Disclosure: Providers must complete CMS-1513 Ownership Forms, declaring all managing directors and individuals with a 5% or greater ownership stake.
• Liability Insurance: A Professional Liability Certificate showing policy numbers and typical $1M/$3M coverage limits must be provided.
• Application Tracking: Providers must save their Application Tracking Number (ATN) to check the status of their submitted enrollment application.

6. Staffing, Training and Background Checks

Delaware enforces strict background screening and training requirements for all Medicaid and HCBS waiver providers to ensure beneficiary safety.

Agencies employing multiple therapists or direct care staff must maintain compliance files for every employee, subject to state audit.

• Criminal Clearances: All staff must pass Delaware State Police and FBI fingerprint-based background checks prior to providing services.
• Registry Screenings: Mandatory pre-employment and ongoing checks against the Delaware Adult Abuse Registry and the Child Protection Registry.
• OIG Exclusion Checks: Monthly screening of all staff and owners against the federal OIG List of Excluded Individuals/Entities (LEIE).
• Waiver Training: DDDS waiver providers must complete mandatory state-sponsored training on HCBS settings rules, person-centered planning, and incident reporting.
• CPR and First Aid: All patient-facing therapists and direct care staff must maintain active, hands-on CPR and Basic First Aid certifications.
• Supervision Documentation: Clinics must maintain written logs demonstrating that licensed OTs are providing required supervision to OTAs per state board rules.

7. Documentation, Policies and Records

Medicaid and HCBS waiver providers must develop and adhere to comprehensive agency policies. These policies are reviewed during the DMAP enrollment process and subsequent state site visits.

Clinical documentation must clearly justify the medical necessity of the services and track measurable progress toward functional goals.

• Care Plans: All OT services must be delivered according to a physician-signed plan of care or a DDDS-approved person-centered service plan.
• Service Logs: Daily treatment notes must include exact start and stop times, specific interventions performed, and the patient's response to treatment.
• Policy Manuals: Agencies must submit written policies covering client assessment, service delivery, emergency preparedness, and HIPAA compliance.
• Incident Reporting: Providers must have a documented process for reporting critical incidents (e.g., injuries, abuse allegations) to DMMA or DDDS within 24 hours.
• Record Retention: All Medicaid billing and clinical records must be securely retained for a minimum of 5 years, or longer if stipulated by specific MCO contracts.
• Discharge Summaries: Documentation must include a formal discharge summary when goals are met or services are no longer medically necessary.

8. Billing, Rates and Claims

Reimbursement for OT services in Delaware is split between the state's Fee-For-Service (FFS) system and the three managed care organizations. Providers must know which entity covers each specific beneficiary.

Prior authorization is a critical component of the billing cycle; failing to secure it before initiating treatment is a primary cause of claim denials.

• FFS Claims: Submitted electronically through the DMAP portal using standard CMS-1500 (professional) or UB-04 (institutional) formats.
• MCO Billing: Claims for DSHP managed care members must be routed directly to the member's assigned MCO (AmeriHealth, Delaware First Health, or Highmark).
• Prior Authorization: Most OT evaluation and treatment codes require prior authorization from the MCO or the state's utilization management contractor.
• NPI Requirements: Claims must include both the billing entity's Type 2 NPI and the rendering therapist's Type 1 NPI.
• Rate Schedules: FFS rates are published in the DMAP Provider Specific Policy Manuals; MCO rates are contracted but generally benchmarked to the state fee schedule.
• Third-Party Liability (TPL): Medicaid is the payer of last resort; providers must bill Medicare or commercial insurance before submitting claims to DMAP or the MCOs.

9. Approval Sequence and Timeline

Becoming a fully billable OT provider in Delaware requires navigating multiple agencies in a strict sequence. Attempting to skip steps will result in automatic application rejections.

The entire process from initial licensure to final MCO network activation typically spans several months.

• Step 1: Professional Licensure: 4 to 8 weeks to process the OT/OTA application and background checks through the DELPROS system.
• Step 2: Medicare PECOS: 45 to 90 days to secure federal Medicare enrollment (mandatory prerequisite for therapy groups).
• Step 3: DMAP Enrollment: 30 to 60 days for the state to process the portal application and issue a Medicaid Provider Identification Number (PID).
• Step 4: CAQH ProView: 1 to 2 weeks to update and attest the provider's CAQH profile, which is required by all Delaware MCOs.
• Step 5: MCO Credentialing: 60 to 120 days to complete credentialing and contracting with AmeriHealth, Delaware First Health, and Highmark.
• Total Timeline: Providers should anticipate a 4 to 8 month end-to-end process before they can bill for all Medicaid populations.

10. Common Denials and Survey Findings

State audits and MCO credentialing reviews frequently uncover administrative and clinical errors. Understanding these common pitfalls can prevent delayed payments and corrective action plans.

Most enrollment denials stem from sequencing errors, while claim denials are typically tied to authorization failures.

• Sequencing Errors: Applying to the DMAP portal before securing an active Delaware DPR license or Medicare PECOS approval.
• Taxonomy Mismatches: Using an NPI taxonomy code on the DMAP application that does not align with the legal entity or the specific OT provider type.
• Incomplete Ownership Disclosure: Failing to list all managing employees and individuals with a 5% or greater ownership stake on the CMS-1513 form.
• Missing Authorizations: Claim denials resulting from delivering therapy services before the MCO has officially approved the prior authorization request.
• Documentation Deficiencies: Audit findings citing missing start/stop times, lack of rendering provider signatures, or failure to document measurable progress in daily logs.
• Lapsed Credentials: Claim denials due to the rendering therapist's state license or CPR certification expiring during the course of treatment.

11. Key Contacts and Resources

Providers should rely on official state and MCO portals for the most current manuals, fee schedules, and enrollment wizards.

Maintaining active accounts with these entities is essential for compliance and timely reimbursement.
