The purpose of this legislation is to expand Medicare coverage to include multi-cancer early detection screening tests. This aims to improve early detection of various types of cancer, potentially leading to better health outcomes for patients. Key provisions of the legislation include the definition of multi-cancer early detection screening tests, which are tests that can detect multiple types of cancer at once. These tests must be approved or cleared by the Food and Drug Administration and must be deemed necessary for early detection of illness by the Secretary of Health and Human Services.
