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

Last reviewed: 2026-08-16

In Washington State, Assistive Technology (AT) Services are covered under multiple Medicaid Home and Community-Based Services (HCBS) programs, including Community First Choice (CFC), New Freedom, and Developmental Disabilities Administration (DDA) waivers. The service encompasses functional evaluations, the provision of adaptive devices, and training designed to increase a participant's independence with activities of daily living and reduce their reliance on paid caregivers.

The single biggest structural barrier to entry for prospective AT providers in Washington is that the state does not issue a standalone "Assistive Technology Provider" facility license. Instead, approval is bifurcated: providers must hold specific Department of Health (DOH) professional licenses (for evaluators) or meet Durable Medical Equipment (DME) standards (for device suppliers), and they must secure a DSHS Core Provider Agreement or regional Area Agency on Aging (AAA) contract before their Health Care Authority (HCA) ProviderOne Medicaid enrollment will yield any authorized client referrals.

1. Service Definition and Scope

Washington defines Assistive Technology Services as adaptive items, equipment, and related services that increase a person's independence with daily tasks (such as eating, dressing, bathing, and medication management) or replace the need for human assistance. This service is authorized under DSHS Medicaid programs when the item is not covered by the standard Medicaid State Plan.

The scope of the service includes the physical devices, functional evaluations by qualified professionals to determine the feasibility of the equipment, and training for the waiver participant or their unpaid caregivers on how to safely use and maintain the technology.

• Covered Goods: Includes adaptive utensils, visual alert systems for hearing impairments, voice-activated systems, and electronic automatic shut-off devices for appliances.
• Evaluations: Covers mobility and environmental assessments to determine the need for devices like specialized wheelchairs, scooters, or smart-home modifications.
• Training: Direct instruction provided to the client or their family members to ensure the safe and effective use of the authorized assistive technology.
• Limitations: Assistive Technology cannot overlap with, replace, or duplicate other similar services provided through the standard Apple Health Medicaid State Plan.
• Replacement Rules: Uninsured items that are damaged, stolen, or lost may typically be replaced only once every two years under DDA waiver rules.
• Service Coordination: Access to AT items is strictly coordinated through DSHS Home and Community Services (HCS), DDA, or Area Agency on Aging (AAA) case managers.

2. Regulatory and Oversight Agencies

Oversight of Assistive Technology Services in Washington is shared between the agency that manages the Medicaid budget and the agencies that administer the specific HCBS waivers. The Washington State Health Care Authority (HCA) serves as the state Medicaid agency, handling all provider enrollment and claims processing through its ProviderOne system.

The Department of Social and Health Services (DSHS) administers the actual waiver programs. Within DSHS, the Aging and Long-Term Support Administration (ALTSA) manages waivers for older adults and individuals with physical disabilities, while the Developmental Disabilities Administration (DDA) manages waivers for individuals with intellectual and developmental disabilities.

• Washington State Health Care Authority (HCA): Manages Apple Health Medicaid enrollment and the ProviderOne MMIS portal https://www.hca.wa.gov
• DSHS Aging and Long-Term Support Administration (ALTSA): Oversees adult HCBS waivers including Community First Choice https://www.dshs.wa.gov/altsa
• DSHS Developmental Disabilities Administration (DDA): Oversees I/DD waivers such as Basic Plus and Core https://www.dshs.wa.gov/dda
• DSHS Background Check Central Unit (BCCU): Processes mandatory fingerprint-based background checks for all provider staff https://www.dshs.wa.gov/ffa/background-check-central-unit
• Washington State Department of Health (DOH): Issues and regulates professional licenses for clinical staff performing AT evaluations https://doh.wa.gov

3. Gatekeeping Prerequisites: Who Can Even Apply

Washington does not require a Certificate of Need (CON) or impose a closed-network moratorium for Assistive Technology Services. However, there is a strict structural precondition: providers cannot simply enroll in Medicaid and begin billing. A provider must establish a contractual relationship with the state or a regional entity before any waiver service authorizations are issued.

The primary gatekeeping barrier is the requirement to secure a DSHS Core Provider Agreement (for DDA waivers) or a direct contract with a regional Area Agency on Aging (AAA) (for ALTSA waivers). Without this contract, an HCA ProviderOne enrollment is functionally useless, as no case manager can authorize payments to the provider.

• Certificate of Need: Genuinely none exists for this service category in Washington State.
• DSHS Core Provider Agreement: Required structural precondition for DDA waiver providers (Form DSHS 10-025) to be eligible to receive client authorizations.
• AAA Subcontracting: For ALTSA waivers, providers often must contract directly with the regional Area Agency on Aging rather than operating as an independent statewide entity.
• State Plan Exhaustion: A strict prerequisite requiring proof that the requested AT is not covered under the standard Apple Health Durable Medical Equipment benefit before waiver funds can be utilized.
• CARE System Authorization: No application for payment is accepted unless the specific AT evaluation or device is pre-authorized by a case manager in the Comprehensive Assessment Reporting Evaluation (CARE) system.

4. Licensure and Certification Requirements

Washington does not issue a distinct "Assistive Technology Provider" facility license. Instead, the state relies on the underlying professional licensure of the individuals performing the services or the business credentials of the entity supplying the goods.

Providers performing clinical evaluations must hold active, unrestricted licenses from the Washington State Department of Health (DOH). Entities that only supply devices must meet standard business licensing requirements and, in many cases, HCA's standards for Durable Medical Equipment (DME) suppliers.

• Clinical Evaluators: Staff performing functional AT assessments must hold active DOH licensure appropriate to their scope of practice, such as an Occupational Therapist (OT), Physical Therapist (PT), or Speech-Language Pathologist (SLP).
• Device Suppliers: Businesses supplying medical-grade AT must meet HCA requirements for DME providers, which may include Medicare enrollment or accreditation from a recognized body.
• Business License: All providers must hold a Washington State Master Business License issued by the Department of Revenue.
• Liability Insurance: Providers must maintain commercial general liability insurance, typically requiring $1 million per occurrence and $2 million aggregate coverage.
• Building Codes: All installed assistive technology must be provided in accordance with applicable state or local building codes and standards of manufacturing.

5. Medicaid Provider Enrollment

All Medicaid providers in Washington must enroll through the HCA ProviderOne portal. There is no separate paper application for a Medicaid provider number; the ProviderOne enrollment process generates the Washington-specific ProviderOne ID required for billing.

Providers must select the correct enrollment type (typically HCBS Waiver Provider or DME Supplier) and submit supplemental paperwork specific to their provider type. HCA aims to process complete in-state applications within 30 days.

• Enrollment Portal: Applications must be submitted electronically through the HCA ProviderOne portal https://www.hca.wa.gov/billers-providers-partners/providerone
• National Provider Identifier (NPI): Providers must obtain an NPI from the NPPES registry and link it to their ProviderOne application.
• Required Documentation: Applicants must upload proof of legal business registration, liability insurance, and an IRS W-9 form matching the application details.
• Processing Timeline: Complete in-state applications take approximately 30 days, while applications with minor deficiencies can take 45 to 60 days.
• Backdating Window: Depending on the waiver and HCA policy, enrollment effective dates may sometimes be backdated to allow billing for services already rendered, provided all qualifications were met at that time.

6. Staffing, Training and Background Checks

Washington enforces strict background check requirements for any personnel interacting with vulnerable adults or children. All direct-care and evaluation staff must clear a fingerprint-based background check before providing services.

Training requirements are dictated by the professional discipline of the staff member and the specific DSHS contract. Licensed professionals must maintain their continuing education units (CEUs), while all staff must complete mandatory Medicaid compliance training.

• Background Checks: Mandatory fingerprint-based checks processed through the DSHS Background Check Central Unit (BCCU) for all staff with direct client contact.
• Professional Credentials: Staff conducting evaluations must maintain active DOH credentials without restrictions or disciplinary actions.
• Continuing Education: Licensed professionals (e.g., OTs, PTs) must meet DOH CEU requirements to keep their licenses active.
• Fraud Training: Agencies must ensure staff complete mandatory Medicaid fraud, waste, and abuse training upon hire and annually thereafter.
• Subcontractor Compliance: If a provider uses subcontractors to install AT devices, those subcontractors must also meet applicable background check and licensing standards.

7. Documentation, Policies and Records

Providers must maintain comprehensive records that satisfy both HCA Medicaid billing standards and DSHS waiver program rules. Documentation must clearly demonstrate that the AT service or device was delivered as authorized and met the client's functional needs.

Failure to maintain adequate records can result in immediate recoupment of funds during an HCA or DSHS audit. All records must be securely stored in compliance with HIPAA regulations.

• Record Retention: Washington requires all Medicaid providers to retain service, billing, and client records for a minimum of six years.
• Evaluation Reports: Clinical assessments must document the client's specific functional limitations, the AT recommended, and exactly how it reduces reliance on paid staff.
• Delivery Receipts: Providers must maintain signed and dated delivery tickets or invoices proving the client physically received the AT device.
• Training Logs: Documentation must include the date, time, and content of any training provided to the client or caregiver on how to use the device.
• Warranty Records: For items over $500, providers must maintain documentation of insurance or an extended warranty as required by DDA rules.

8. Billing, Rates and Claims

Billing for Assistive Technology Services is conducted entirely through the HCA ProviderOne system. Because AT encompasses a wide variety of custom devices and evaluations, reimbursement is often authorized as a specific dollar amount based on an invoice rather than a standard statewide unit rate.

Providers cannot bill for any service or device that has not been explicitly pre-authorized by the client's case manager in the CARE system. The authorization must successfully cross over from CARE to ProviderOne before a claim will pay.

• Billing System: Claims are submitted electronically via ProviderOne using HIPAA-compliant 837P formats or the Direct Data Entry (DDE) interface.
• Authorization Requirement: Claims will automatically deny if the service is not pre-authorized in the DSHS CARE system and linked to the provider's ProviderOne ID.
• Procedure Codes: Services are typically billed using specific HCPCS codes (e.g., T2028 for specialized medical equipment) as designated on the CARE authorization.
• Reimbursement Rates: Device reimbursement is usually based on the actual invoice cost plus a contracted administrative markup, as approved by the case manager.
• Third-Party Liability: Providers must verify that no other insurance (including Medicare or standard Medicaid State Plan) covers the item before billing the HCBS waiver.

9. Approval Sequence and Timeline

Becoming a fully approved and billing AT provider in Washington is a multi-step process that requires coordinating with the Department of Revenue, DSHS, and HCA. The sequence must be followed carefully to avoid application rejections.

The entire process from business registration to receiving the first CARE authorization typically takes 2 to 4 months, depending heavily on the speed of DSHS contract execution and BCCU background checks.

• Step 1: Obtain a Washington Master Business License and an NPI number (1 to 2 weeks).
• Step 2: Apply for a DSHS Core Provider Agreement or regional AAA contract (30 to 60 days).
• Step 3: Submit the Medicaid enrollment application via the HCA ProviderOne portal (30 to 60 days).
• Step 4: Complete BCCU background checks for all applicable staff and evaluators (1 to 3 weeks).
• Step 5: Receive the ProviderOne ID, finalize the DSHS contract, and begin accepting CARE authorizations from case managers.

10. Common Denials and Survey Findings

Both HCA and DSHS conduct routine audits and post-payment reviews of waiver providers. For Assistive Technology providers, findings are almost exclusively related to administrative errors, lack of delivery documentation, or billing ahead of authorizations.

Understanding these common pitfalls is essential for maintaining compliance and avoiding costly recoupments of Medicaid funds.

• Enrollment Denial: Applications are frequently delayed or denied due to missing or mismatched IRS W-9 information compared to the ProviderOne entry.
• Claim Denial: Billing for a date of service that occurs before the ProviderOne enrollment effective date or before the CARE authorization start date.
• Audit Finding: Failure to provide a signed delivery receipt proving that the AT device was actually delivered to the client's residence.
• Audit Finding: Supplying an item that is covered under the Medicaid State Plan without first receiving and documenting a formal State Plan denial.
• Audit Finding: Billing for an AT device that does not meet applicable state or local manufacturing standards or building codes.

11. Key Contacts and Resources

Prospective Assistive Technology providers should utilize the official state resources provided by HCA and DSHS to navigate the enrollment and contracting process. These portals contain the most current manuals, forms, and fee schedules.

Regional contacts, such as local Area Agencies on Aging or DDA regional offices, are also critical for securing the necessary contracts to receive client referrals.
