The bill amends existing Washington insurance and public health statutes (including RCW 48.43.830 and provisions affecting RCW 41.05.845 and RCW 74.09.840) to change procedures for prior authorization of health care services and prescription drugs. It is a procedural change, not the creation of a new crime or criminal penalty. The amendments require carriers, health plans for public employees, and managed care organizations (MCOs) to follow specific timelines and processes for prior authorization requests and to make prior authorization requirements and written clinical review criteria available electronically on request. The bill prescribes decision and notification timeframes for electronic and nonelectronic requests, distinguishing standard and expedited requests, and sets deadlines for when carriers or MCOs must request additional information if a submission is insufficient. It requires clinical review criteria to be peer-reviewed, evidence-based, to accommodate new and emerging information about appropriateness for Black and Indigenous people, other people of color, gender, and underserved populations, and to be evaluated and updated at least annually. The bill also requires carriers and MCOs to establish and maintain prior authorization application programming interfaces (APIs) consistent with final CMS rules and to create an interoperable electronic process or API to automate prior authorization for covered prescription drugs, with the prescription drug exchange requirement to support transactions beginning January 1, 2027. The APIs must indicate that denials or authorizations of less intensive services or different drugs are adverse benefit determinations subject to the grievance and appeal process under RCW 48.43.535. The insurance commissioner must update legislative health care policy committees starting September 13, 2023 and at least every six months through September 13, 2026. The text available omits some edited language and full technical standards, leaves certain references (for example “the authority”) undefined here, and does not include the complete amended texts of RCW 41.05.845 and RCW 74.09.840, so some implementation details and final operative language are unclear from these excerpts.

If enacted, health plans (including those for public employees) and managed care organizations will have to speed up and formalize how they handle prior authorization requests: quicker deadlines for electronic and nonelectronic requests, public, peer‑reviewed clinical criteria that are updated at least yearly, and a requirement to create interoperable electronic processes and APIs for prior authorization of services and prescription drugs by January 1, 2027. That will directly affect carriers/MCOs (who must build and operate these systems and meet the timing and reporting rules), providers and facilities (who will need to submit requests and any missing information more quickly), and enrollees (who should see faster decisions and clearer grounds for appeals when denials or lower‑level or different drug authorizations occur). The practical consequences are likely higher upfront and ongoing costs for carriers and MCOs to develop or buy technology, change staffing and workflow to meet short response windows, and review clinical criteria annually, while providers may need to adapt their submission practices to avoid delays. Important implementation details are missing from the provided text—most notably the final technical standards for the APIs, some edits to related statutes, and the definition of "the authority"—so the exact technical requirements, costs, and timelines for compliance are uncertain from these excerpts.
