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, 2025. 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 an electronic voucher for eligible individuals to use at network pharmacies.

Additionally, the bill outlines the responsibilities of network pharmacies and the reimbursement process from the prescription drug purchasing consortium. Pharmacies can charge a dispensing fee of up to $10 and must submit claims for reimbursement within 30 days. The consortium will invoice insulin manufacturers for the costs incurred and may impose fines on manufacturers that fail to comply with payment requirements. The authority is also tasked with providing information on manufacturer patient assistance programs and will adopt necessary rules for the implementation of the act.
