California - Assistive Technology Services — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-09

The California Department of Developmental Services (DDS) funds Assistive Technology Services through the HCBS Waiver for Californians with Developmental Disabilities, requiring prospective providers to secure vendorization approval from the specific Regional Center governing their geographic catchment area before any services can be billed. Applicants must submit their vendorization requests through the centralized DDS Provider Directory, a digital portal that routes the application to the local Regional Center for review against Title 17 California Code of Regulations standards.

This service encompasses evaluations, specialized devices, and training designed to increase a consumer's functional capability and reduce reliance on paid staff. Because California does not issue a distinct facility license for assistive technology providers, approval hinges on submitting forms DS 1890 and DS 1891, alongside proof of appropriate professional credentials such as a RESNA Assistive Technology Professional (ATP) certification or active state licensure in occupational, physical, or speech therapy.

1. Service Definition and Scope

In California, Assistive Technology Services under the DDS HCBS Waiver include the evaluation of the consumer's assistive technology needs, the purchasing or leasing of devices, and the training required to use them effectively. The primary objective is to enhance the individual's independence, integrate them more fully into their community, and decrease the need for direct human assistance.

The scope covers off-the-shelf commercial products, customized equipment, and specialized software that directly address the functional limitations identified in the consumer's Individual Program Plan (IPP). It explicitly excludes items that are considered standard household goods, recreational equipment without a direct habilitative purpose, or devices that are covered under the Medicaid State Plan (Medi-Cal) as standard Durable Medical Equipment (DME).

2. Regulatory and Oversight Agencies

The California Department of Developmental Services (DDS) serves as the primary operating agency for the HCBS Waiver for Californians with Developmental Disabilities, setting the statewide standards for provider vendorization and service delivery. DDS promulgates the regulations found in Title 17 of the California Code of Regulations and manages the centralized Provider Directory used for enrollment.

The Department of Health Care Services (DHCS) acts as the single state Medicaid agency, maintaining ultimate authority over waiver administration and federal financial participation. At the local level, California's 21 independent Regional Centers act as the direct contracting and oversight entities, conducting the actual vendorization reviews, approving rates, and monitoring ongoing provider compliance.

3. Gatekeeping Prerequisites: Who Can Even Apply

California employs a strict geographic catchment area system for DDS vendorization. A prospective assistive technology provider must apply for vendorization exclusively through the specific Regional Center that holds jurisdiction over the physical address of the provider's business office. Providers cannot apply directly to the state or to a Regional Center outside their geographic location for initial vendorization.

Furthermore, the applicant must possess the underlying professional licensure or certification required to perform the specific type of assistive technology service they intend to offer before initiating the application. There is no generic assistive technology agency license; the entity must be legally established and the individual practitioners must hold active, unencumbered credentials (such as an OT license or RESNA certification) at the time the DS 1890 form is generated.

4. Licensure and Certification Requirements

Because California does not issue a distinct facility or agency license for Assistive Technology Services, the state relies on the professional licensure of the individuals conducting the evaluations and training. Providers must meet the qualifications outlined in Title 17, Division 2, Chapter 3, Subchapter 2 of the California Code of Regulations, which typically requires practitioners to be licensed healthcare professionals or certified technology specialists.

Firms selling equipment without providing clinical evaluation or training may be vendored simply as retail or wholesale equipment suppliers, provided they hold a valid California seller's permit and local business licenses. However, any provider billing for the evaluation or training components must employ staff with specific credentials, such as a Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) certification.

5. Medicaid Provider Enrollment

Enrollment as an HCBS waiver provider for this service is synonymous with the DDS vendorization process, which is now conducted entirely online through the DDS Provider Directory. Applicants initiate the process by creating an account, selecting their service category, and submitting initial data, which prompts the system to generate drafts of the Vendor Application (DS 1890) and the Applicant/Vendor Disclosure Statement (DS 1891).

Once the local Regional Center approves the vendorization and assigns a vendor number and service code, the provider is eligible to receive authorizations. While standard Medi-Cal providers use the DHCS PAVE portal, DDS waiver providers primarily interact with the Regional Center system for HCBS enrollment, though dual enrollment in PAVE is required if the provider also intends to bill the Medi-Cal State Plan for standard DME.

6. Staffing, Training and Background Checks

Providers must ensure that all staff interacting directly with consumers meet the minimum qualifications specified in the vendorization approval and Title 17 regulations. This includes verifying that professional licenses and certifications remain active and unencumbered throughout the duration of employment.

While assistive technology providers who only ship devices may have limited background check requirements, any staff conducting in-home evaluations, installations, or training must undergo criminal background clearances. Agencies must also ensure staff are trained in mandated reporting requirements for suspected abuse or neglect of dependent adults and children.

7. Documentation, Policies and Records

Assistive technology providers must maintain comprehensive records that align with the consumer's Individual Program Plan (IPP) and justify the services billed. Title 17 requires providers to keep these records for a minimum of five years from the date of service or final payment, whichever is later, and make them available for audit by DDS or the Regional Center.

Documentation must clearly separate the costs of the evaluation, the physical device, and the training. For devices exceeding certain cost thresholds, providers must maintain records of warranties, insurance, and the specific customization work performed to meet the consumer's needs.

8. Billing, Rates and Claims

Reimbursement for Assistive Technology Services is processed through the DDS eBilling system, managed by the Regional Centers. Rates for these services are typically established based on the provider's Usual and Customary rate, meaning the provider cannot charge the Regional Center more than they charge the general public for the same device or service.

For highly customized equipment or specialized evaluations where a usual and customary rate does not exist, the rate is negotiated directly with the vendoring Regional Center. Providers must receive an approved Purchase of Service (POS) authorization from the Regional Center before delivering the service or ordering the equipment, as retroactive authorizations are generally not permitted.

9. Approval Sequence and Timeline

The vendorization process begins when the applicant submits their initial information through the DDS Provider Directory. By statute, the vendoring Regional Center has 15 days to conduct an initial review to determine if the applicant meets the basic requirements and to issue a checklist of required documents, which triggers the generation of the DS 1890 and DS 1891 forms.

Once the applicant uploads all requested documents and signs the forms, the application enters the Decision stage. The Regional Center then has 45 days to approve or deny the completed vendorization package. If approved, the system automatically generates a vendor number and the provider's profile becomes active in the directory.

10. Common Denials and Survey Findings

Applications for assistive technology vendorization are frequently delayed or denied due to administrative errors in the Provider Directory, such as discrepancies between the entity name on the DS 1891 and the name registered with the California Secretary of State. Another common barrier is applying to the wrong Regional Center; applications must go to the center governing the provider's physical office location.

During audits, providers often face recoupment of funds for failing to maintain adequate documentation proving that Medi-Cal or private insurance was billed first for items that qualify as standard DME. Auditors also frequently cite providers for billing training hours that lack corresponding signed service logs or failing to secure a Purchase of Service (POS) authorization prior to ordering expensive equipment.

11. Key Contacts and Resources

Prospective providers should begin by identifying their local Regional Center and reviewing the specific vendorization guidelines posted on that center's website. The DDS Provider Directory serves as the central hub for the application process and offers technical support for account creation and form submission.

For regulatory guidance, providers must familiarize themselves with Title 17 of the California Code of Regulations, which dictates the statutory requirements for all DDS vendors. Questions regarding Medi-Cal State Plan billing for DME should be directed to the DHCS Provider Enrollment Division.
