Concerning the health technology assessment program.
SB 5915 amends Washington State's health technology assessment program to establish clearer processes for reviewing medical technologies. It requires the committee to prioritize technologies based on Medicare recommendations, safety concerns, high costs, or significant usage variations, and mandates systematic evidence-based assessments from designated federal centers. The bill sets timelines for reviews (180 days for initial assessments) and requires transparency through public comment periods and written explanations for denied requests. It directly affects state health programs (like Medicaid) and providers by determining which medical technologies qualify as covered benefits based on safety, effectiveness, and cost evidence.

MINOR
The document changed from a draft bill identifier to an official certification of enrollment, confirming that Senate Bill 5915 was passed by both the Senate and the House of Representatives in the 2026 session. This addition serves as the formal legal record proving the bill's approval and readiness for the Governor's signature, rather than altering the bill's actual policy content.
TECHNICAL
Added official certification text, vote counts, and signatures from the Senate President and House Speaker to validate the bill's passage.
Removed the draft bill number 'S-3451.1', indicating the text is no longer in a preliminary drafting stage.
