The bill seeks to modernize Washington State's all-payer claims database by updating reporting requirements, data disclosure standards, and the selection criteria for the lead organization managing the database. It allows the health care authority to either serve as the lead organization or select one through a competitive procurement process. Key amendments include the removal of the term "proprietary financial information" from the definitions section and the establishment of protocols to ensure data security and privacy, including the use of unique identifiers and strict access controls. The lead organization is also required to develop a financial sustainability plan and establish advisory committees to guide data policy and release processes, with these provisions set to expire on July 1, 2026.

Additionally, the bill enhances transparency in health care pricing and data sharing by mandating a review of existing transparency programs by December 31, 2025, and requiring the health care authority to provide an update to the legislature on current data reporting requirements. It emphasizes the importance of online data access, security, and responsiveness to research requests. The authority is tasked with consulting stakeholders to make recommendations for improving the state common measure set, which is essential for enhancing health outcomes. The provisions in sections 1 and 3 through 7 of the act will take effect on July 1, 2026.
