Washington - Case Management Service — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-08-16

In Washington State, Medicaid Home and Community-Based Services (HCBS) case management—defined as assessment, person-centered service planning, referral, and monitoring—is not an open-enrollment provider category. Washington does not license or cover independent, private "Case Management Agencies" under a distinct authority for its core HCBS waivers (such as Community First Choice, COPES, or the DDA waivers). Instead, the state operates a closed, delegated system where HCBS case management is structurally assigned to state employees, regional Area Agencies on Aging (AAAs), or designated Lead Entities.

The single biggest structural barrier to entry is this closed delegation model. A private agency cannot simply apply to be an HCBS case manager in Washington. To provide Medicaid-funded care coordination or case management, an agency must either successfully bid to become a Care Coordination Organization (CCO) subcontracted under a designated Health Home Lead Entity, become a licensed Behavioral Health Agency (BHA) contracted with a Managed Care Organization (MCO) for Targeted Case Management, or secure a specific procurement contract with a regional AAA. Therefore, this guide focuses on the Health Home CCO and BHA Targeted Case Management pathways, which are the closest applicable authorities for private entities seeking to provide Medicaid case management in Washington.

1. Service Definition and Scope

Because Washington delegates core HCBS waiver case management to state and regional government entities, private providers typically engage in case management through the Medicaid Health Home program (Section 2703) or Targeted Case Management (TCM). The Health Home program provides intensive care coordination for high-risk Medicaid beneficiaries with chronic conditions, integrating medical, behavioral, and long-term services and supports.

Under these alternative pathways, the scope of service remains aligned with federal case management definitions: conducting comprehensive assessments, developing Person-Centered Service Plans (PCSPs), coordinating referrals across the full service package, and monitoring client progress and health and safety.

2. Regulatory and Oversight Agencies

The Washington State Health Care Authority (HCA) is the single state Medicaid agency responsible for administering Apple Health and the ProviderOne system. HCA directly oversees the Health Home program and contracts with Lead Entities and Managed Care Organizations (MCOs).

The Department of Social and Health Services (DSHS) operates the state's HCBS waivers through its Aging and Long-Term Support Administration (ALTSA) and Developmental Disabilities Administration (DDA). The Department of Health (DOH) is responsible for licensing facilities and agencies, including Behavioral Health Agencies that provide TCM.

3. Gatekeeping Prerequisites: Who Can Even Apply

Washington enforces strict structural preconditions that block standalone case management applications. For core HCBS waivers, the network is entirely closed to private providers; case management is statutorily delegated to AAAs and DDA state employees.

For a private entity to provide Medicaid case management, they must secure a subcontract. If pursuing the Health Home model, the provider must be selected as a Care Coordination Organization (CCO) by an HCA-contracted Lead Entity. If pursuing behavioral health TCM, the provider must first obtain a DOH license and secure a network contract with an Apple Health MCO or Behavioral Health Administrative Services Organization (BH-ASO).

4. Licensure and Certification Requirements

Washington does not issue a generic "Case Management Agency" license. Providers operating as Health Home CCOs do not require a specific state facility license but must maintain a standard Washington State business license and meet the certification and training standards dictated by their Lead Entity contract.

Providers delivering Targeted Case Management for behavioral health populations must be licensed by the Department of Health (DOH) as a Behavioral Health Agency (BHA). This requires submitting a detailed application, policies and procedures, and passing a DOH facility inspection.

5. Medicaid Provider Enrollment

All providers serving Washington Apple Health members must enroll through the HCA ProviderOne system, even if they only bill through Managed Care Organizations. Enrollment requires both a Type 1 (individual) and Type 2 (organizational) National Provider Identifier (NPI).

Health Home CCOs typically enroll as non-billing servicing providers or under specific taxonomy codes directed by their Lead Entity, as the Lead Entity holds the primary billing contract with HCA. BHA TCM providers enroll as facility/agency billing providers.

6. Staffing, Training and Background Checks

Staffing qualifications depend on the specific case management pathway. Health Home Care Coordinators typically must hold a bachelor's degree in a social services or health field, or be a licensed nurse, and must complete a mandatory two-day HCA Health Home training.

All staff with unsupervised access to vulnerable adults or children must pass a fingerprint-based background check through the DSHS Background Check Central Unit (BCCU). Agencies must maintain these clearances on file and renew them periodically.

7. Documentation, Policies and Records

Washington requires rigorous documentation of case management activities, utilizing state-mandated IT systems. Health Home CCOs must use the Predictive Risk Intelligence System (PRISM) to identify risk factors and document Health Action Plans (HAPs).

All case management providers must maintain Person-Centered Service Plans (PCSPs) that comply with the federal HCBS Settings Rule (42 CFR 441.301). Records must be retained for a minimum of six years per the HCA Core Provider Agreement.

8. Billing, Rates and Claims

Billing structures vary significantly by program. Health Home services are reimbursed on a tiered Per Member Per Month (PMPM) basis, depending on the client's level of engagement (e.g., outreach, intensive care coordination). CCOs bill their Lead Entity, which in turn bills HCA.

Targeted Case Management is typically billed fee-for-service or via MCO encounters using specific HCPCS codes (like T1017) in 15-minute increments. Claims must include both the billing and rendering NPIs to avoid automatic ProviderOne denials.

9. Approval Sequence and Timeline

Because standalone enrollment is not permitted, the approval sequence begins with securing a contract. A prospective provider must first negotiate a subcontract with a Health Home Lead Entity or an MCO.

Once the contract is secured, the provider obtains necessary DOH licensure (if applicable), completes ProviderOne enrollment, and finalizes MCO credentialing. The entire runway from initial contract negotiation to billing the first claim typically takes 4 to 9 months.

10. Common Denials and Survey Findings

The most frequent barrier at the application stage is attempting to enroll as a case management agency without a required Lead Entity or MCO contract, resulting in immediate rejection by HCA.

During audits and surveys, the most common findings relate to inadequate documentation of client contact and failure to update care plans. Auditors frequently cite providers for failing to demonstrate that the Person-Centered Service Plan was driven by the client's own goals.

11. Key Contacts and Resources

Prospective providers should begin by reviewing the HCA Health Home program guidelines and identifying the designated Lead Entities in their region. For behavioral health TCM, providers must consult the DOH BHA licensing division.

ProviderOne enrollment support is managed by HCA, and technical assistance for the PRISM system is available directly through the HCA Health Home team.
