California - I/DD Services — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-09

The California Department of Developmental Services (DDS) administers the HCBS Waiver for Californians with Developmental Disabilities (CA.0336), funding services from habilitation to supported living. Approval to provide these services requires prospective agencies to first obtain vendorization through one of California's 21 local Regional Centers before they can enroll as Medi-Cal providers.

Providers operate under Title 17, Division 2 of the California Code of Regulations, which dictates service codes, staffing ratios, and facility requirements. Once vendored by the catchment area's Regional Center, the provider submits an application to the Department of Health Care Services (DHCS) via the Provider Application and Validation for Enrollment (PAVE) portal to receive reimbursement.

1. Service Definition and Scope

California's HCBS Waiver for Californians with Developmental Disabilities (CA.0336) provides a comprehensive array of services designed to support individuals in their own homes and communities. These services are authorized through an Individual Program Plan (IPP) developed by the local Regional Center.

The service array includes Supported Living Services (SLS), day programs, behavioral supports, and residential facility services. Providers are assigned specific service codes based on the exact nature of the support they deliver.

• Target Population: Individuals with a developmental disability originating before age 18 that constitutes a substantial handicap.
• Supported Living Services (Service Code 896): Services provided to adults in their own homes to support independent living.
• Behavior Management Program (Service Code 515): Day programs focusing on individuals with severe behavioral challenges.
• In-Home Respite (Service Code 862): Intermittent support provided in the family home to relieve primary caregivers.

2. Regulatory and Oversight Agencies

Oversight of I/DD services in California is bifurcated between the agency that manages the waiver and the agency that administers the broader Medicaid (Medi-Cal) program. Local implementation is delegated to a network of non-profit Regional Centers.

Facility-based services also require licensure from the state's social services department before vendorization can occur.

• Department of Developmental Services (DDS): Administers the HCBS waiver and oversees Regional Centers (https://www.dds.ca.gov).
• Department of Health Care Services (DHCS): The single state Medicaid agency responsible for Medi-Cal provider enrollment (https://www.dhcs.ca.gov).
• Regional Centers: 21 non-profit corporations contracting with DDS to coordinate local services and vendor providers (https://www.dds.ca.gov/rc/).
• Community Care Licensing Division (CCLD): A division of the Department of Social Services that licenses residential and day facilities (https://www.cdss.ca.gov/inforesources/community-care-licensing).

3. Gatekeeping Prerequisites: Who Can Even Apply

California utilizes a strict localized gatekeeping model known as vendorization. A provider cannot simply apply to the state to become an I/DD waiver provider; they must apply to the specific Regional Center responsible for the geographic catchment area where their site or operating office is located.

Furthermore, entities seeking to provide services exclusively to individuals in the Self-Determination Program cannot apply through the standard Provider Directory, except for Financial Management Services (FMS).

• Regional Center Vendorization: The mandatory approval process required before any Medi-Cal enrollment or service provision can begin.
• Catchment Area Restriction: Applications must be submitted to the specific vendoring Regional Center governing the provider's physical location.
• Provider Directory Profile: Applicants must create a profile in the DDS Provider Directory (https://caddsprod.servicenowservices.com/spd) to initiate the process.
• Self-Determination Program Exclusion: Standard vendorization does not apply to most services under the Self-Determination Program.

4. Licensure and Certification Requirements

Not all I/DD services require a facility license. In-home services like Supported Living Services (SLS) are unlicensed but heavily regulated by Title 17. Facility-based services, such as Adult Residential Facilities (ARFs) or day programs, must obtain a license from the Community Care Licensing Division (CCLD) prior to vendorization.

All providers must submit a comprehensive Program Design to the Regional Center, detailing how they will meet Title 17 requirements for their specific service code.

• Title 17 Compliance: All providers must adhere to Title 17, Division 2 of the California Code of Regulations.
• CCLD Facility License: Required for site-based services like Adult Day Programs and Adult Residential Facilities.
• Program Design: A mandatory, detailed operational plan submitted to the Regional Center outlining service delivery, staffing, and curriculum.
• Fire Clearance: Required for all licensed facilities prior to CCLD approval and Regional Center vendorization.

5. Medicaid Provider Enrollment

After receiving a vendor number and service code from the Regional Center, the provider must enroll in Medi-Cal to receive federal HCBS waiver matching funds. This is completed through the DHCS Provider Application and Validation for Enrollment (PAVE) portal.

Providers must maintain active vendorization status to remain enrolled in Medi-Cal. Loss of Regional Center vendorization results in immediate termination of the Medi-Cal provider agreement.

• PAVE Portal: The DHCS online system used for all Medi-Cal provider enrollment applications (https://pave.dhcs.ca.gov).
• Vendor Number Requirement: The unique identifier issued by the Regional Center, required on the PAVE application.
• National Provider Identifier (NPI): Required for all healthcare providers enrolling in Medi-Cal.
• Application Fee: Subject to federal Medicaid institutional application fee requirements unless waived or enrolled as an individual practitioner.

6. Staffing, Training and Background Checks

Staffing qualifications are dictated by Title 17 and the specific service code. Direct Support Professionals (DSPs) working in licensed facilities must complete specific certification training.

All personnel with consumer contact must undergo criminal background clearances through the Department of Justice before beginning employment.

• Live Scan Fingerprinting: Mandatory Department of Justice (DOJ) and FBI criminal background checks for all direct care staff.
• DSP Training: Direct Support Professionals in residential facilities must complete Year 1 and Year 2 DSP certification.
• Administrator Qualifications: Facility administrators must possess a valid CCLD Administrator Certificate.
• CPR and First Aid: All direct care staff must maintain current certification in CPR and First Aid.

7. Documentation, Policies and Records

Providers must maintain extensive documentation demonstrating that services are delivered in accordance with the consumer's Individual Program Plan (IPP). Records must be kept for a minimum of five years.

California enforces strict Special Incident Reporting (SIR) timelines, requiring providers to notify the Regional Center and applicable licensing bodies within 24 hours of specific events.

• IPP Alignment: Service delivery records must directly correlate with the goals and objectives outlined in the consumer's IPP.
• Special Incident Reporting (SIR): Mandated reporting of abuse, injury, or missing persons to the Regional Center within 24 hours.
• Record Retention: All consumer and billing records must be retained for at least five years from the date of service.
• Grievance Policy: Providers must maintain and distribute a written consumer grievance procedure.

8. Billing, Rates and Claims

Reimbursement rates for I/DD services are established by DDS and vary by service code and geographic region. California is currently implementing a multi-year rate reform based on rate models developed to standardize payments.

Providers submit claims to their vendoring Regional Center using the DDS eBilling system, not directly to the Medi-Cal MMIS.

• DDS eBilling System: The portal used by vendored providers to submit attendance and invoices to Regional Centers.
• Rate Models: Standardized rate structures implemented by DDS to ensure equitable funding across service categories.
• Service Codes: Billing must utilize the specific 3-digit service code assigned during the vendorization process.
• Attendance Logs: Providers must maintain daily, signed attendance or service logs to substantiate all billed units.

9. Approval Sequence and Timeline

The approval process is sequential and cannot be expedited. Providers must first secure any necessary facility licenses, then apply for Regional Center vendorization, and finally enroll in Medi-Cal.

The entire process from initial Program Design submission to active Medi-Cal enrollment typically takes 6 to 12 months, depending on the complexity of the service and facility licensure requirements.

• Initial Review: The Regional Center has 15 calendar days to review the initial vendorization request in the Provider Directory.
• Program Design Review: Regional Centers typically take 45 days to review and approve or reject a submitted Program Design.
• Vendorization Issuance: Once all requirements are met, the Regional Center issues a vendor number and service code.
• PAVE Processing: DHCS Medi-Cal enrollment processing can take an additional 90 to 120 days after vendorization.

10. Common Denials and Survey Findings

Vendorization applications are frequently delayed or denied due to incomplete Program Designs that fail to address all Title 17 requirements for the specific service code.

During quality assurance surveys, the most common citations involve inadequate documentation of service hours and failure to report special incidents within the mandated 24-hour timeframe.

• Incomplete Program Design: Applications rejected because the curriculum or staffing plan does not meet Title 17 standards.
• Background Check Failures: Staff beginning work prior to the clearance of Live Scan fingerprinting.
• IPP Misalignment: Billing for services or supports that are not explicitly authorized in the consumer's IPP.
• Late SIRs: Citations issued for failing to report special incidents to the Regional Center within 24 hours.

11. Key Contacts and Resources

Prospective providers should begin by identifying their local Regional Center and reviewing the DDS vendorization guidelines. The DDS website hosts the Provider Directory and rate schedules.

For Medi-Cal enrollment questions, providers must interface with the DHCS Provider Enrollment Division.
