HCA Washington Explained-why It Matters More Than Ever
The Washington State Health Care Authority (HCA) is the government agency that manages the state's two largest health care purchasers: Washington Apple Health (Medicaid) and the state employee health plan, purchasing whole-person health care for nearly one-third of residents while using its purchasing power to secure high-quality care at the best price.
Core Mission and Scope of HCA Washington
HCA serves as the central health purchaser for Washington State, overseeing coverage for approximately 2.2 million residents through Apple Health and managing health benefits for roughly 180,000 state employees and retirees. The agency was established to consolidate health care purchasing authority and ensure equitable, high-quality care through innovative health policies and strategic purchasing decisions.
On July 1, 2024, HCA expanded its responsibilities by taking over the state's community behavioral health system from the Department of Social and Health Services (DSHS), including community-based mental health services and substance use disorder prevention and treatment. This landmark transfer positioned HCA as the unified administrator for both physical and behavioral health services under one agency.
Primary Functions and Services
The agency executes several critical functions that directly impact Washington residents' access to health care:
- Administers Washington Apple Health (Medicaid), covering low-income adults, children, pregnant women, elderly adults, and people with disabilities
- Manages the Washington State Health Benefit Exchange for individual health insurance marketplace plans
- Purchases health benefits for state employees, retirees, and elected officials
- Operates the Washington State All-Payer Health Care Claims Database (WA-APCD) to increase transparency and identify cost trends
- Implements value-based purchasing strategies, aiming to tie 90% of state-financed health care payments to quality and value
- Oversees the Cost Transparency Board to curb spending growth and inform policy decisions

Value-Based Purchasing Transformation
HCA's Long-term Value-based Purchasing Roadmap outlines a comprehensive vision for paying for health outcomes rather than volume of services, with key priorities extending through 2025. The agency's multi-payer primary care transformation, launched in October 2020, combines lump-sum financial relief for primary care providers with population-based payments placed at risk.
This model includes the Comprehensive Primary Care Payment (CPCP) designed to provide stability for practices, plus a Transition of Care Fee offering temporary support up to three years for infrastructure and staffing changes. The approach specifies total spend on primary care across all payers as a proportion of total cost of care, going beyond payment reform to individual practices.
- Increasing access to care across underserved communities
- Improving affordability and reducing cost growth drivers
- Infusing health equity concepts into all purchasing initiatives
- Instituting prospective incentive payments on quarterly basis for performance improvement
- Building integrated care delivery models with enhanced infrastructure
Behavioral Health Integration Milestone
The July 1, 2024 transfer marked a historic consolidation of Washington's health care system, bringing community behavioral health under HCA's umbrella. This includes community-based mental health services and substance use disorder prevention and treatment programs previously managed by DSHS.
Following the transfer, HCA renamed website sections to reflect expanded services: "Free or low-cost health care" became "Health care services and supports," and "Billers and providers" became "Billers, providers, and partners". The URL structure changed accordingly, with new addresses launching after business close on June 28, 2024.
Why HCA Matters More Than Ever in 2026
As Washington faces rising health care costs and persistent access disparities, HCA's role as the state's largest purchaser has become increasingly critical. The agency's purchasing power enables it to negotiate better rates and demand higher quality standards from providers across the state.
HCA's integration of behavioral health under one roof addresses a decades-long fragmentation problem, ensuring that mental health and substance use treatment receive equal priority with physical health services. This unified approach aligns with evidence showing that integrated care produces better outcomes and lower total costs.
HCA purchases whole-person health care for nearly a third of the state's residents. We use our purchasing power to get high-quality care at the best price. We provide equitable, high-quality health care through innovative health policies and purchasing strategies.
The agency's data-driven approach through WA-APCD provides unprecedented transparency into Washington's health care system, enabling policymakers to make informed decisions about cost containment and quality improvement. This transparency is essential as the state grapples with health care spending growing faster than inflation.
