South Carolina - Autism Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-08-16

Autism Spectrum Disorder (ASD) Services in South Carolina are covered under the Medicaid State Plan for EPSDT-eligible individuals under 21 ([Autism Spectrum Disorder Services](https://www.scdhhs.gov/resources/programs-and-initiatives/autism-spectrum-disorder-services)). South Carolina does not have a state licensing board for behavior analysts, meaning there is no state-issued ABA license ([South Carolina ABA Licensure Requirements - CertifyndABA](https://certifyndaba.com/resources/licensure/south-carolina)). Instead, the state relies entirely on national certification through the Behavior Analyst Certification Board (BACB) combined with Medicaid provider enrollment.

The single biggest structural barrier to entry is the mandatory Administrative Service Organization (ASO) review process. Applicants must first apply through the SCDHHS portal, after which the South Carolina Department of Disabilities and Special Needs (SCDDSN) acts as the ASO to review and approve the prospective ABA provider before Medicaid enrollment is finalized ([Autism Services](https://www.scdhhs.gov/communications/autism-services)).

1. Service Definition and Scope

Autism Spectrum Disorder (ASD) Services in South Carolina are covered under the Medicaid State Plan for medically eligible individuals up to age 21 ([Autism Spectrum Disorder Services](https://www.scdhhs.gov/resources/programs-and-initiatives/autism-spectrum-disorder-services)). Services include Applied Behavior Analysis (ABA) assessments, supervision, and direct interventions designed to ameliorate the core deficits of autism.

• Service Name: Autism Spectrum Disorder (ASD) Services
• Target Population: Medicaid-eligible individuals under age 21 at risk for or diagnosed with ASD
• Core Modality: Applied Behavior Analysis (ABA)
• Delivery Model: Tiered model utilizing BCBAs for assessment and supervision, and RBTs for direct therapy
• Coverage Authority: Medicaid State Plan under the EPSDT mandate

2. Regulatory and Oversight Agencies

Because South Carolina does not have a state licensing board for behavior analysts, oversight is split between the state Medicaid agency and the national certification board. The South Carolina Department of Health and Human Services (SCDHHS) (https://www.scdhhs.gov) manages the Medicaid state plan, while the South Carolina Department of Disabilities and Special Needs (SCDDSN) (https://ddsn.sc.gov) acts as the Administrative Service Organization (ASO) for provider approval.

• Medicaid Authority: South Carolina Department of Health and Human Services (SCDHHS) (https://www.scdhhs.gov)
• Administrative Service Organization: South Carolina Department of Disabilities and Special Needs (SCDDSN) (https://ddsn.sc.gov)
• Credentialing Body: Behavior Analyst Certification Board (BACB) (https://www.bacb.com)
• Managed Care Oversight: SCDHHS Division of Managed Care (https://www.scdhhs.gov)

3. Gatekeeping Prerequisites: Who Can Even Apply

South Carolina does not require a Certificate of Need (CON) or competitive procurement (RFP) for ABA providers. However, there is a strict structural precondition: providers cannot simply enroll and bill. They must pass a mandatory ASO review by SCDDSN ([Autism Services](https://www.scdhhs.gov/communications/autism-services)).

• State Licensure Prerequisite: None exists; South Carolina does not license behavior analysts
• National Certification Gate: Active BACB certification (BCBA, BCaBA, or RBT) is a hard prerequisite for application acceptance
• ASO Approval Gate: Mandatory review and approval by SCDDSN acting as the Administrative Service Organization after initial SCDHHS screening
• NPI Requirement: Must obtain a Type 1 (Individual) or Type 2 (Organization) National Provider Identifier from NPPES before applying
• Network Status: Open enrollment; no closed networks or moratoria currently in effect for ASD services

4. Licensure and Certification Requirements

South Carolina is one of the few states without a behavior analyst practice act or state licensure ([South Carolina ABA Licensure Requirements - CertifyndABA](https://certifyndaba.com/resources/licensure/south-carolina)). Therefore, SCDHHS relies entirely on the Behavior Analyst Certification Board (BACB) to establish provider qualifications for Medicaid reimbursement.

• State License: Not applicable in South Carolina
• Lead Provider Credential: Board Certified Behavior Analyst (BCBA) or BCBA-D in good standing with the BACB
• Mid-Level Credential: Board Certified Assistant Behavior Analyst (BCaBA) practicing under BCBA supervision
• Direct Care Credential: Registered Behavior Technician (RBT) or equivalent BACB-recognized technician credential
• Credential Verification: Primary source verification via the BACB registry required during Medicaid enrollment

5. Medicaid Provider Enrollment

Enrollment is conducted entirely online through the SCDHHS Provider Enrollment Web Portal (https://providerservices.scdhhs.gov/ProviderEnrollmentWeb/). Providers must enroll with the state first before they can credential and contract with South Carolina's Medicaid Managed Care Organizations (MCOs).

• Enrollment Portal: SCDHHS Provider Enrollment Web Portal (https://providerservices.scdhhs.gov/ProviderEnrollmentWeb/)
• Provider Type: Must select the specific Autism Spectrum Disorder (ASD) provider specialty codes during enrollment
• Application Fee: Subject to standard CMS institutional provider application fee if enrolling as a group or clinic, unless waived
• Risk Category: Subject to high-risk provider screening alignment, which may include fingerprint-based background checks
• Revalidation: Required at least every five years per SCDHHS policy

6. Staffing, Training and Background Checks

Staffing requirements mirror BACB standards for supervision and ethics. SCDHHS also mandates standard Medicaid background screenings for all rendering providers, supervisors, and agency owners.

• Background Checks: Fingerprint-based state (SLED) and federal (FBI) criminal background checks required for high-risk providers
• Exclusion Screening: Monthly checks against OIG LEIE and SAM.gov databases for all staff
• Supervision Ratios: Must adhere to BACB guidelines, typically requiring 5 percent of RBT hours to be supervised by a BCBA
• CPR/First Aid: Direct care staff must maintain active CPR and First Aid certifications
• Mandated Reporting: All clinical staff must be trained in South Carolina Department of Social Services (SCDSS) child abuse reporting protocols

7. Documentation, Policies and Records

SCDHHS enforces strict documentation standards outlined in the Autism Spectrum Disorder (ASD) Services Provider Manual. Providers must maintain comprehensive clinical and billing records that are subject to state and MCO audits.

• Diagnostic Requirement: Comprehensive diagnostic evaluation confirming ASD by a qualified healthcare professional prior to ABA initiation
• Treatment Plan: Individualized ABA treatment plan that must be updated at least every six months
• Session Notes: Must include date, start and stop times, specific interventions used, client response, and rendering provider signature
• Record Retention: Clinical and financial records must be retained for a minimum of five years
• Telehealth Policy: Must comply with SCDHHS telehealth guidelines using appropriate modifiers for remote supervision or parent training

8. Billing, Rates and Claims

ASD services are billed using standard CPT codes through the South Carolina Medicaid MMIS or the respective MCO portals. Rates are published on the SCDHHS fee schedule and are subject to periodic updates.

• Billing System: SCDHHS Web Tool for fee-for-service claims or individual MCO clearinghouses for managed care claims
• Procedure Codes: Standard Category I and III ABA CPT codes including 97151 for assessment and 97153 for direct treatment
• Prior Authorization: Required for all ongoing ABA treatment following the initial assessment phase
• MCO Contracting: Providers must separately credential and contract with SC MCOs like Molina Healthcare or Select Health after state enrollment
• Fee Schedule: Published annually by SCDHHS with providers needing to monitor July 1 rate updates

9. Approval Sequence and Timeline

The end-to-end process from NPI generation to billing readiness involves state screening, ASO approval, and MCO credentialing. Delays most frequently occur during the ASO review phase or if credentialing documents are incomplete.

• Step 1: Obtain NPI from NPPES and ensure BACB credentials are active
• Step 2: Submit online application via SCDHHS Provider Enrollment Web Portal
• Step 3: SCDHHS initial screening and routing to SCDDSN for ASO review, typically processed within thirty business days ([South Carolina Provider Enrollment](https://www.centenevision.com/providers/ProviderNotice/SouthCarolina-FAQ.html))
• Step 4: SCDDSN ASO review and approval of ABA provider qualifications
• Step 5: Final Medicaid enrollment and effective date assignment, which can retroactively begin ninety days prior to receipt ([South Carolina Provider Enrollment](https://www.centenevision.com/providers/ProviderNotice/SouthCarolina-FAQ.html))
• Step 6: MCO credentialing and contracting, which adds 60 to 90 days post-Medicaid enrollment

10. Common Denials and Survey Findings

Applications and claims are frequently delayed or denied due to credentialing mismatches or documentation errors. SCDHHS and MCO audits focus heavily on medical necessity and the presence of required supervision documentation.

• Enrollment Denial: Failure to pass the SCDDSN ASO review due to incomplete or inactive BACB credential verification
• Application Return: Mismatched NPI, Tax ID, or legal business name between NPPES, the IRS, and the SCDHHS portal
• Claim Denial: Billing for direct therapy without an active prior authorization on file with the MCO
• Audit Finding: Missing exact start and stop times or rendering provider signatures on daily session notes
• Audit Finding: Failure to document the required BCBA supervision percentage for RBTs in the clinical record

11. Key Contacts and Resources

Providers should bookmark the SCDHHS provider portal and the ASD specific manual pages for ongoing reference. The ASO and MCO contacts are also critical for day-to-day operations and authorization inquiries.
