The proposed bill establishes a new chapter in Title 70 RCW to create a health care entity registry, which mandates that health care entities report specific information to the Department of Health annually starting June 30, 2027. This information includes the entity's legal name, business address, operational locations, identification numbers, ownership details, organizational structure, and financial reports. Certain small health care provider organizations are exempt from these reporting requirements, and the information collected will be considered public, with specific confidentiality protections for individual taxpayer identification numbers.

Additionally, the bill outlines penalties for non-compliance, including civil penalties for entities that fail to submit complete reports or provide false information, with penalties varying based on the size and revenue of the health care entity. The Department of Health is also tasked with developing an interactive public tool by January 1, 2028, to allow access to the reported data, and it may audit health care entities to ensure compliance. The bill includes provisions for the department to adopt necessary rules for implementation and to consult with the attorney general regarding noncompliance.
