The bill establishes an emergency insulin program in Washington state, allowing eligible individuals to access a 30-day supply of insulin for a maximum out-of-pocket cost of $10, starting January 1, 2026. To qualify, individuals must be Washington residents, not enrolled in medical assistance or prescription drug coverage that limits their cost-sharing for insulin to $35 or less, possess a valid prescription, and have less than a seven-day supply of insulin available. The program will be administered by the health care authority, which will provide a process for individuals to attest to their eligibility and receive an electronic voucher for insulin at a network pharmacy.

Additionally, the bill outlines the responsibilities of network pharmacies, including accepting vouchers and submitting claims for reimbursement to the prescription drug purchasing consortium. The consortium is required to reimburse pharmacies within 30 days and invoice insulin manufacturers for the costs incurred. Manufacturers must remit payment within 30 days of receiving an invoice, with penalties for non-compliance. The health care authority is also tasked with providing information on manufacturer patient assistance programs and will adopt necessary rules for the implementation of the act.
