Maryland - Autism Service — Licensing, Medicaid Enrollment and Startup Requirements
Last reviewed: 2026-08-16
In Maryland, Autism Services primarily consist of Applied Behavior Analysis (ABA) delivered to Medicaid beneficiaries under 21 via the EPSDT benefit, as well as specialized services under the 1915(c) Autism Waiver managed jointly by the Maryland Department of Health (MDH) and the Maryland State Department of Education (MSDE). Services are delivered by Licensed Behavior Analysts (LBAs) and Registered Behavior Technicians (RBTs).
The single biggest structural barrier to entry for ABA providers in Maryland is the mandatory dual-enrollment and credentialing gateway. Providers cannot simply enroll in Medicaid fee-for-service; they must first secure an active Medicaid provider number through the ePREP portal and subsequently register and credential with Carelon Behavioral Health Maryland, the state's Behavioral Health Administrative Services Organization (BHASO), which strictly manages the ABA network and authorizations.
1. Service Definition and Scope
Maryland Medicaid covers medically necessary Applied Behavior Analysis (ABA) therapy for Medical Assistance Program enrolled participants under age 21. The state also operates the Autism Waiver, providing community-based therapeutic services to prevent institutionalization.
ABA services include comprehensive assessment, treatment plan development, and direct behavioral interventions. Services must be evidence-based and delivered in home, clinic, or community settings.
- Authority: COMAR 10.09.28 Applied Behavior Analysis Services
- Target Population: Medicaid EPSDT beneficiaries under 21 and Autism Waiver participants
- Covered Modalities: Direct intervention, assessment, family training, and group adaptive behavior treatment
- Excluded Services: Academic tutoring, vocational training, and respite care unless specifically authorized under the waiver
2. Regulatory and Oversight Agencies
Oversight is bifurcated between the Maryland Department of Health (MDH) and its designated contractors. MDH's Medical Care Programs division handles baseline Medicaid policy and enrollment.
Carelon Behavioral Health Maryland acts as the BHASO, managing the ABA program's clinical, operational, and provider network functions. The Maryland State Department of Education (MSDE) co-manages the Autism Waiver.
- Primary Agency: Maryland Department of Health (MDH) Medical Care Programs
- Behavioral Health ASO: Carelon Behavioral Health Maryland administers the ABA Program
- Waiver Co-Administrator: Maryland State Department of Education (MSDE) administers the Autism Waiver
- Licensing Board: Maryland Board of Professional Counselors and Therapists licenses LBAs
3. Gatekeeping Prerequisites: Who Can Even Apply
Maryland does not require a Certificate of Need (CON) or a competitive RFP procurement to become an ABA provider. However, there is a strict structural precondition: mandatory affiliation with the state's Behavioral Health ASO.
An applicant cannot bill Medicaid directly for ABA without first completing the ePREP enrollment and then securing an approved registration and credentialing status with Carelon Behavioral Health Maryland. For the Autism Waiver, providers must also be selected by the participant's multidisciplinary team.
- ASO Network Mandate: Mandatory registration and credentialing with Carelon Behavioral Health Maryland
- NPI Requirement: Must possess a unique National Provider Identifier (NPI) registered via NPPES before applying
- Waiver Selection: Autism Waiver providers must be chosen by the family and Service Coordinator via the Person-Centered Plan process
- Facility Need Review: None required in Maryland for ABA clinics
- Moratoria: No current enrollment moratoria for ABA agencies
4. Licensure and Certification Requirements
Maryland licenses behavior analysts at the state level. Agencies must ensure all supervising practitioners hold active state licenses, while frontline technicians must hold national certification.
The Maryland Board of Professional Counselors and Therapists issues the Licensed Behavior Analyst (LBA) credential. Maryland does not issue a distinct facility license for ABA agencies; instead, agencies operate under the professional licenses of their clinical directors.
- Supervising Professional: Licensed Behavior Analyst (LBA) issued by the Maryland Board of Professional Counselors and Therapists
- Mid-Level Supervisor: Board Certified Assistant Behavior Analyst (BCaBA) practicing under LBA supervision
- Direct Care Staff: Registered Behavior Technician (RBT) credentialed by the BACB
- Agency Licensure: No distinct facility license exists; approval is based on individual practitioner licensure and Medicaid group enrollment
5. Medicaid Provider Enrollment
All ABA providers must enroll in the Maryland Medicaid Program through the electronic Provider Revalidation and Enrollment Portal (ePREP). Note that Maryland is transitioning to the MPRIME portal in October 2026.
Providers can enroll as individual ABA providers or as group ABA providers. The ePREP system handles initial enrollment, revalidation, and demographic updates.
- Enrollment Portal: ePREP (electronic Provider Revalidation and Enrollment Portal)
- Future Portal: MPRIME (Maryland Provider Registration and Information Management Enterprise) launching October 2026
- Provider Types: Individual ABA Provider and Group ABA Provider
- Application Fee: Subject to CMS institutional provider application fee of approximately $709 for groups unless waived by Medicare enrollment
6. Staffing, Training and Background Checks
Maryland mandates strict background screening and ongoing training for all personnel interacting with vulnerable minors.
Agencies must maintain documentation of criminal history records checks and verify that no staff appear on state or federal exclusion lists.
- Background Check: Criminal History Records Check (CHRC) via the Maryland Criminal Justice Information System (CJIS)
- Exclusion Screening: Monthly checks against the OIG LEIE and Maryland Medicaid exclusion lists
- Mandated Reporting: Documented training on Maryland child abuse and neglect reporting protocols
- CPR and First Aid: All direct care staff must maintain active in-person CPR and First Aid certification
7. Documentation, Policies and Records
Clinical and administrative documentation must comply with COMAR regulations and Carelon's ABA Provider Manual.
Providers must maintain comprehensive treatment plans, session notes, and, for waiver participants, integration with the MSDE Person-Centered Plan.
- Treatment Plans: Must be updated and re-authorized every 6 months via Carelon
- Session Notes: Must include date, location, start and stop times, specific interventions used, and the LBA or RBT signature
- Waiver Documentation: Monthly tracking logs and Reportable Event forms for Autism Waiver participants
- Record Retention: Medical records must be retained for a minimum of 6 years or until the minor reaches age 24, whichever is longer
8. Billing, Rates and Claims
ABA claims are not submitted directly to the state MMIS; they must be routed through Carelon Behavioral Health Maryland.
Providers utilize specific portals for claims submission and eligibility verification, primarily Availity Essentials and ProviderConnect.
- Clearinghouse and Portal: Availity Essentials is preferred for EDI while ProviderConnect is used for direct data entry
- Billing Codes: Standard CPT codes including 97151 for assessment and 97153 for adaptive behavior treatment
- Prior Authorization: 100 percent of ongoing ABA treatment requires prior authorization from Carelon
- Eligibility Verification: Conducted via the Maryland Eligibility Verification System (EVS) or Carelon portals
9. Approval Sequence and Timeline
The end-to-end process requires sequential approvals from the licensing board, the state Medicaid agency, and the BHASO.
Providers should expect the entire process to take 3 to 6 months from initial LBA licensure to final Carelon network activation.
- Step 1: Obtain LBA licensure from the Maryland Board of Professional Counselors and Therapists taking 4 to 8 weeks
- Step 2: Secure NPI and establish legal entity Tax ID taking 1 to 2 weeks
- Step 3: Submit Medicaid enrollment via ePREP taking 30 to 60 days for state review
- Step 4: Register and complete credentialing with Carelon Behavioral Health Maryland taking 45 to 90 days
10. Common Denials and Survey Findings
Applications and claims are frequently delayed or denied due to administrative mismatches between state and federal databases.
Audits by MDH or Carelon often target inadequate supervision documentation or billing for services without an active prior authorization.
- ePREP Denials: Mismatched legal business names or Tax IDs between IRS records, NPPES, and ePREP
- Credentialing Delays: Failure to provide complete work history or lapsed BACB certifications for RBTs
- Audit Findings: Missing start and stop times on RBT session notes or lack of documented LBA supervision
- Claim Denials: Submitting claims to Carelon before the official ePREP Medicaid effective date is established
11. Key Contacts and Resources
Providers must utilize specific state and ASO contact channels for enrollment, billing, and policy inquiries.
Maintaining access to the ePREP portal and Carelon's provider resources is essential for ongoing compliance.
