District of Columbia - Autism Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-09

In the District of Columbia, Autism Spectrum Disorder (ASD) services, including Applied Behavior Analysis (ABA), are covered under the Medicaid State Plan (SPA 23-0009) for children and adolescents under age 21, administered by the Department of Health Care Finance (DHCF). The service is not managed under a distinct HCBS waiver but is integrated into the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit.

To become an approved provider, agencies and independent practitioners must enroll directly with DHCF through the Medicaid portal. The most significant structural precondition is that all rendering providers must hold active licensure or certification from the DC Department of Health (DC Health) before Medicaid enrollment can be initiated.

1. Service Definition and Scope

Under DC Medicaid SPA 23-0009, ASD services encompass comprehensive behavioral analytic therapies, including ABA, designed to treat children and adolescents under age 21 diagnosed with autism spectrum disorder.

Services are delivered by a tiered workforce of licensed professionals and certified technicians, focusing on improving core deficits associated with ASD through structured, evidence-based interventions.

• Target Population: Medicaid-eligible children and adolescents under age 21 with an ASD diagnosis.
• Service Modalities: Comprehensive and focused ABA, including assessment, treatment planning, and direct intervention.
• Delivery Settings: Home, community, and clinic-based settings.
• Supervision: Direct care provided by technicians must be supervised by a licensed behavior analyst or other qualified healthcare professional.

2. Regulatory and Oversight Agencies

The primary oversight for Medicaid enrollment and reimbursement of ASD services is the Department of Health Care Finance (DHCF).

Professional licensure and certification for the individuals delivering the services are regulated by the DC Department of Health (DC Health).

• Medicaid Authority: Department of Health Care Finance (DHCF) (https://dhcf.dc.gov/)
• Licensing Authority: DC Department of Health (DC Health) (https://dchealth.dc.gov/)
• Medicaid Enrollment Portal: DC Medicaid Provider Enrollment Portal (Maximus) (https://www.dc-medicaid.com/)

3. Gatekeeping Prerequisites: Who Can Even Apply

Before applying to enroll as a Medicaid provider for ASD services in the District of Columbia, applicants must meet specific structural prerequisites.

There is no Certificate of Need (CON) or closed network moratorium for ABA services under the State Plan, but professional licensure is an absolute prerequisite.

• Professional Licensure: All independent practitioners and supervising analysts must hold an active license from DC Health.
• Agency Structure: Agencies must employ or contract with licensed professionals capable of supervising ancillary providers.
• NPI Requirement: Applicants must obtain a National Provider Identifier (NPI) specific to their provider type and taxonomy.
• Location: Providers must have a physical service location or established service area within DC or the immediate surrounding metropolitan area.

4. Licensure and Certification Requirements

The District of Columbia requires all individuals rendering ABA services to be licensed or certified by DC Health.

Agencies do not receive a separate "ABA facility license" but must ensure all affiliated staff hold the appropriate credentials.

• Supervising Professionals: Must be licensed as a Psychologist, LICSW, Licensed Professional Counselor, or Licensed Behavior Analyst by DC Health.
• Technicians: Must hold certification (e.g., Registered Behavior Technician) and practice under the direct supervision of a licensed professional.
• Board Certification: Supervising analysts typically hold BCBA certification from the Behavior Analyst Certification Board (BACB) in addition to DC licensure.
• Scope of Practice: All services must be delivered within the scope of practice defined by the respective DC Health licensing board.

5. Medicaid Provider Enrollment

Providers must enroll through the DC Medicaid Provider Enrollment Portal managed by Maximus.

Both individual practitioners and group practices/agencies must complete the enrollment process, linking rendering providers to the billing entity.

• Portal: Applications are submitted via the DC Medicaid Web Portal (https://www.dc-medicaid.com/).
• Provider Type: Applicants must select the appropriate provider type and specialty code for behavioral health/ABA services.
• Required Documents: W-9, DC Master Business License, liability insurance, and copies of all professional licenses.
• Group Affiliation: Agencies must enroll all performing providers and link them to the agency's billing NPI.

6. Staffing, Training and Background Checks

Agencies must maintain strict staffing ratios and ensure all personnel meet training and background check requirements.

Supervision of technicians must comply with both BACB standards and DC Medicaid policy.

• Background Checks: All staff must undergo criminal background checks and child abuse registry clearances.
• Training: Technicians must complete required training (e.g., 40-hour RBT training) and demonstrate competence before providing independent care.
• Supervision Ratios: Agencies must maintain appropriate supervisor-to-technician ratios as defined by clinical standards.
• CPR/First Aid: All direct care staff must maintain current CPR and First Aid certification.

7. Documentation, Policies and Records

Providers must maintain comprehensive clinical and administrative records to support Medicaid billing and ensure quality of care.

Treatment plans must be individualized, data-driven, and regularly updated based on the client's progress.

• Treatment Plans: Must include baseline data, measurable goals, and specific intervention strategies.
• Session Notes: Detailed notes must be kept for every encounter, including date, time, duration, and specific behaviors targeted.
• Supervision Logs: Documentation of supervision provided to technicians must be maintained.
• Retention: Records must be retained for a minimum of six years or as specified by DC Medicaid policy.

8. Billing, Rates and Claims

Reimbursement for ASD services is based on the DC Medicaid fee schedule, utilizing standard CPT codes for ABA.

Prior authorization is typically required for ongoing treatment following the initial assessment.

• Codes: Billing utilizes standard Category I and III CPT codes for adaptive behavior services (e.g., 97151-97158).
• Prior Authorization: Required for treatment services; must be submitted with a comprehensive assessment and treatment plan.
• Fee Schedule: Rates are published on the DHCF website and are subject to periodic updates.
• Modifiers: Specific modifiers may be required to denote the credentials of the rendering provider (e.g., BCBA vs. RBT).

9. Approval Sequence and Timeline

The process to become a fully enrolled provider involves multiple sequential steps, starting with professional licensure.

Timelines can vary based on application completeness and the volume of applications under review by DHCF.

• Step 1: Obtain professional licensure from DC Health (timeline varies).
• Step 2: Obtain NPI and DC Master Business License.
• Step 3: Submit Medicaid enrollment application via the Maximus portal.
• Step 4: DHCF review and credentialing (typically 30-60 days).
• Step 5: Receive Medicaid welcome letter and provider ID.

10. Common Denials and Survey Findings

Applications and claims are frequently delayed or denied due to administrative errors or lack of required documentation.

Providers must ensure strict adherence to supervision and documentation standards to avoid recoupment during audits.

• Enrollment Denials: Often caused by expired licenses, missing business licenses, or mismatched NPI information.
• Claim Denials: Frequently result from missing prior authorizations or billing for services outside the approved authorization period.
• Audit Findings: Common issues include inadequate session notes, missing supervision documentation, or failure to update treatment plans.
• Credentialing Lapses: Failure to revalidate Medicaid enrollment or renew professional licenses on time.

11. Key Contacts and Resources

Providers should utilize official DC government resources for the most current information on policies, rates, and enrollment procedures.

The DHCF and DC Health websites are the primary sources for regulatory updates.
