INSULIN Act of 2026

The INSULIN Act of 2026 requires health insurance plans to limit insulin copayments to $35 per 30-day supply starting in 2027, with plans choosing to cap costs at 25% of the negotiated price after 2028. The bill also mandates that pharmacy benefit managers pass all rebates and discounts related to insulin directly to health plans rather than retaining them. Additional provisions include measures to speed up the approval process for generic and biosimilar insulin products, establish a pilot program to provide affordable insulin to uninsured individuals in 10 states, and create a resource center and hotline to help uninsured people access assistance programs.
