Preserving access to preventive services by clarifying state authority and definitions.

SB 5967 requires most health plans in Washington to cover specific preventive services without cost-sharing, including evidence-based care rated A or B by the U.S. Preventive Services Task Force and CDC-recommended immunizations. It clarifies that coverage must follow federal guidelines as of June 30, 2025, and updates requirements for plans issued after April 1, 2026. The bill also gives Washington’s Department of Health authority to issue immunization guidance without needing formal rulemaking. This directly affects health insurance plans and Washington residents accessing preventive care like screenings, vaccinations, and wellness visits.
