The Screen to Save Act would require Medicare, Medicaid, and private health insurance plans to provide free annual screening mammograms for women starting at age 30, with the new coverage taking effect on January 1, 2027. Currently, Medicare covers mammograms for women 40 and older, and this bill would expand that coverage to include women in their thirties at no cost to patients. The legislation also modifies frequency rules to allow one screening mammogram per year for eligible women while prohibiting coverage for women under 30. The bill affects millions of Medicare and Medicaid beneficiaries as well as individuals with private insurance coverage, though it does not specify federal funding amounts or appropriations needed to implement the changes.
