Concerning coverage requirements for prosthetic limbs and custom orthotic braces.

SB 5629 mandates that large group health plans in Washington, issued or renewed on or after January 1, 2026, must include coverage for medically necessary prosthetic limbs and custom orthotic braces. This coverage applies when devices are needed for daily living, essential job activities, or to maximize physical function. The bill also requires coverage for materials, instruction, and reasonable repair or replacement of these devices. It prohibits denying coverage for individuals with disabilities if similar services would be covered for non-disabled persons and requires health plans to report claims data.
