The bill introduces a new section to chapter 41.05 RCW aimed at enhancing access to primary care, behavioral health, and affordable hospital services for public employees and their dependents in Washington State. It defines key terms such as "Contractor" and outlines the reimbursement structure for various healthcare services. Starting January 1, 2027, contractors must adhere to specific reimbursement rates for in-network and out-of-network hospitals, with particular provisions for hospitals primarily engaged in pediatric care and rural critical access hospitals. The bill mandates that reimbursement for primary care and nonfacility-based behavioral health services cannot be less than 150% of the total amount Medicare would have reimbursed for similar services.

Additionally, the bill stipulates that contractors must provide cost and quality of care data to the authority for monitoring and enforcement purposes. It requires the authority to report on the impacts of the new reimbursement policies by December 31, 2030, and again by December 31, 2034, assessing their effects on network access, enrollee premiums, and state expenditures. The bill also allows for the adoption of rules to implement its provisions and enforce compliance, including the possibility of levying fines.
