This bill aims to enhance the administration of vision benefits in Washington State by amending existing laws and introducing new regulations. It reenacts and amends RCW 48.200.020 and RCW 41.05.017, while adding new sections to chapters 48.200 and 48.43 RCW. Key provisions include the definition of a "vision benefit manager," which is established to oversee the determination and utilization of benefits related to vision services and materials. The bill outlines specific prohibitions for vision benefit managers and health carriers, such as preventing them from offering different reimbursement amounts for covered vision services among providers of the same profession, requiring providers to purchase from suppliers in which they have a financial interest, and imposing excessive cost-sharing on enrollees.

Additionally, the bill mandates that vision benefit managers and health carriers must adhere to equitable reimbursement practices and credentialing standards for providers. It also clarifies that these regulations apply to contracts entered into or renewed after the effective date of the new provisions. The bill includes a provision for the insurance commissioner to adopt necessary rules for implementation and sets an effective date of January 1, 2026, for the new regulations.
