A bill for an act relating to insurance coverage for prescription insulin drugs.

HF 405 requires most health insurance plans in Iowa to cap out-of-pocket costs for prescription insulin at $25 per prescription for up to a 31-day supply. It directly affects people with diabetes who use insulin and are covered under health insurance plans that provide prescription drug coverage. The bill sets this $25 limit for four types of insulin (rapid-acting, short-acting, intermediate-acting, and long-acting) and applies to plans issued or renewed on or after January 1, 2026. It excludes certain insurance types like Medicare supplements, workers’ compensation, and dental/vision plans. The Iowa Insurance Commissioner will implement rules to enforce this requirement.
