The bill introduces a new section to chapter 48.43 of the Revised Code of Washington (RCW) that mandates health carriers to provide coverage for all FDA-approved HIV antiviral drugs without requiring prior authorization, step therapy, or other utilization management protocols for health plans issued or renewed on or after January 1, 2027. However, if the FDA has approved therapeutic equivalents for a drug, the health plan is only required to cover at least one of those equivalents without such management protocols.

Additionally, the bill reenacts and amends RCW 41.05.017 to include the new section on HIV antiviral drug coverage among the provisions applicable to health plans providing medical insurance under this chapter. This ensures that the new coverage requirements are integrated into the existing legal framework governing health insurance in Washington State.
