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

HB 2242 clarifies and preserves access to preventive health services covered by most Washington health insurance plans. It requires plans issued after April 1, 2026, to cover evidence-based services like vaccinations, cancer screenings, and other preventive care without cost-sharing, based on current U.S. Preventive Services Task Force (USPSTF) ratings and CDC recommendations. The bill updates coverage requirements to align with federal guidelines as of June 30, 2025, and allows the state Department of Health to issue immunization guidance without standard rulemaking. This directly affects Washington residents using health insurance and insurers offering new or updated plans, ensuring consistent access to preventive care without adding new requirements for patient consent or immunization mandates.
