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

Last reviewed: 2026-09-10

The Indiana Family and Social Services Administration (FSSA) covers Applied Behavior Analysis (ABA) and related autism-specific interventions primarily through the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit for members under age 21, and as Behavioral Support Services under the Family Supports Waiver (FSW) and Community Integration and Habilitation (CIH) Waiver. The Indiana Professional Licensing Agency (IPLA) Behavioral Health and Human Services Licensing Board issues the mandatory state license required for all Board Certified Behavior Analysts (BCBAs) operating in the state.

Approval requires individual practitioners to hold this active IPLA licensure before submitting a Type 11 Behavioral Health Provider enrollment application via the Indiana Health Coverage Programs (IHCP) Provider Healthcare Portal. Group practices must subsequently secure credentialing and contracts with individual Managed Care Entities (MCEs) to receive reimbursement for the majority of Medicaid beneficiaries enrolled in Hoosier Healthwise, Hoosier Care Connect, or the Healthy Indiana Plan.

1. Service Definition and Scope

In Indiana, ABA therapy is defined as the design, implementation, and evaluation of environmental modifications, using behavioral stimuli and consequences, to produce socially significant improvement in human behavior. For Medicaid members under 21, these services are authorized under EPSDT when deemed medically necessary following a Comprehensive Diagnostic Evaluation (CDE).

For adult waiver participants, similar interventions are billed as Behavioral Support Services under the FSW or CIH waivers, focusing on training, supervision, and behavioral intervention plans to integrate individuals into the community.

2. Regulatory and Oversight Agencies

The Indiana Family and Social Services Administration (FSSA) Office of Medicaid Policy and Planning (OMPP) administers the Medicaid program and oversees provider enrollment. The Indiana Professional Licensing Agency (IPLA) regulates the professional practice of behavior analysts.

Managed Care Entities (MCEs) handle the day-to-day administration, prior authorizations, and claims processing for the majority of Medicaid members receiving ABA services.

3. Gatekeeping Prerequisites: Who Can Even Apply

Indiana does not require a Certificate of Need (CON) or a Request for Proposals (RFP) procurement process to become an ABA provider. The state operates an open enrollment model for IHCP.

The absolute structural precondition for enrollment is that the supervising provider must hold an active Behavior Analyst license issued by the IPLA. Without this license, the IHCP Provider Healthcare Portal will automatically reject a Type 11 Behavioral Health Provider application for ABA specialties.

4. Licensure and Certification Requirements

The IPLA's Behavioral Health and Human Services Licensing Board issues the Behavior Analyst license. Applicants must demonstrate current certification by the Behavior Analyst Certification Board (BACB).

Out-of-state providers seeking to provide telehealth services to Indiana Medicaid members must also obtain this IPLA license and may apply for a Telemedicine Provider Certification.

5. Medicaid Provider Enrollment

Providers enroll through the IHCP Provider Healthcare Portal. ABA providers typically enroll as Type 11 (Behavioral Health Provider).

Group practices must enroll the group entity first, and then link individual licensed rendering providers to the group's IHCP profile.

6. Staffing, Training and Background Checks

ABA services are typically delivered in a tiered model. The licensed BCBA designs and supervises the treatment plan, while Registered Behavior Technicians (RBTs) implement the direct line therapy.

All staff with direct member contact must undergo criminal history checks in accordance with Indiana Administrative Code (460 IAC 6-10-5 for waiver services).

7. Documentation, Policies and Records

IHCP requires rigorous documentation to support the medical necessity of ABA services. A Comprehensive Diagnostic Evaluation (CDE) by a qualified healthcare professional is required to initiate services.

Treatment plans must be individualized, data-driven, and updated at least every six months to demonstrate measurable progress or justify modifications.

8. Billing, Rates and Claims

ABA services are billed using standard Category I and Category III CPT codes (e.g., 97151-97158). Reimbursement rates are established by OMPP and published on the IHCP Fee Schedule.

Because most members are enrolled in managed care, claims are submitted directly to the member's MCE, which may have specific billing guidelines and prior authorization requirements.

9. Approval Sequence and Timeline

The end-to-end process from licensure to billing can take several months. Providers must sequence their applications correctly, as IHCP enrollment cannot begin without IPLA licensure.

MCE credentialing is a separate, subsequent step that cannot be initiated until the provider has an active IHCP Provider ID.

10. Common Denials and Survey Findings

Enrollment applications are frequently rejected for administrative errors, particularly mismatches between IRS documentation and the application.

During audits or revalidation, providers often face recoupments for failing to maintain adequate session notes or failing to report changes in ownership or service locations within the required timeframe.

11. Key Contacts and Resources

Providers should utilize the IHCP Provider Healthcare Portal for enrollment and updates. The IHCP Provider Enrollment unit handles application processing and can be reached for status inquiries.

For licensure questions, the IPLA Behavioral Health and Human Services Licensing Board is the primary contact.
