What this bill would do
This bill, known as the "INSULIN Act of 2026," aims to lower insulin costs and increase patient protections. It requires group health plans and insurance issuers to cap cost-sharing for selected insulin products at $35 per 30-day supply. The legislation also mandates that pharmacy benefit managers pass 100 percent of insulin-related rebates back to health plans. Additionally, it establishes a pilot program and a resource center to assist uninsured individuals in accessing affordable insulin. Finally, the bill seeks to increase competition by expediting the review of biosimilar products and ensuring more timely access to generics.

Who it would affect, and how
Potential Positive Impacts for People
-
Lower Out-of-Pocket Costs for Insured Individuals: Group health plans and insurance issuers must provide coverage for selected insulin products without applying a deductible and with cost-sharing capped at $35 per 30-day supply for plan years before 2028, or a lower amount starting in 2028 (Section 101/Section 2729A).
-
Removal of Medical Management Barriers: Health plans are prohibited from imposing prior authorization or other medical management requirements on selected insulin products, except when clinically justified for safety and quantity limits (Section 101/Section s 2729A(f)).
-
Increased Rebates to Health Plans: Pharmacy benefit managers and other entities must remit 100 percent of all insulin-related rebates and discounts back to the group health plan (Section 201/Section 2799A-13).
-
Support for Uninsured Individuals: A 5-year pilot program will award grants to 10 states to help uninsured people purchase or dispense insulin through health centers and pharmacies (Section 401/Section 399V-8).
-
Access to Information and Assistance: The bill funds a resource center and a 24/7 hotline to help uninsured individuals find assistance programs and navigate access to insulin (Section 403/Section 8).
-
Faster Access to Competitors: The bill allows the Secretary to expedite the development and review of competitive biosimilar products to increase market competition (Section 302/Section 351(k)(10)).
Potential Negative Impacts for People
-
Potential for Higher Costs for Out-of-Network Care: While the bill limits costs for selected products within a network, insurance plans are not required to provide these benefits for out-of-network providers and may impose higher cost-sharing for those services (Section 101/Section 2729A(c)).
-
Cost-Sharing Caps May Decrease Over Time: For plan years beginning on or after January 1, 2028, the $35 cap may be lowered to 25 percent of the negotiated price of the selected insulin product net of concessions (Section 101/Section 2729A(a)(2)(B)).
