SB 264 Wisconsin Senate · 2025-2026 Regular Session

Relating to: coverage of breast cancer screenings by the Medical Assistance program and health insurance policies and plans. (FE)

SB 264 requires health insurance plans and the Medical Assistance program to cover specific breast cancer screenings without out-of-pocket costs for enrollees. It defines two key types of screenings: "diagnostic breast examinations" (used to evaluate symptoms or abnormalities, like mammograms) and "supplemental breast screening examinations" (for high-risk individuals without symptoms, using MRI or ultrasound). The bill prohibits cost-sharing (such as copays) for all diagnostic screenings and for the first supplemental screening per year, while allowing limited cost-sharing for additional supplemental screenings in the same year. This directly affects individuals with health insurance or Medical Assistance who require these screenings, particularly those at higher risk for breast cancer.
