The bill introduces a new section to chapter 41.05 RCW aimed at ensuring access to primary care, behavioral health, and affordable hospital services for public employees and their dependents. 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 the care of children 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 requires contractors to provide cost and quality of care information to the authority for monitoring and enforcement purposes. It stipulates that premiums must reflect changes in reimbursement rates and mandates the authority to report on the impacts of this section by December 31, 2030, and again by December 31, 2034. The authority is also empowered to adopt rules for implementation and compliance enforcement. Overall, the bill aims to enhance the affordability and accessibility of healthcare services for public employees in Washington.
