This bill amends Title XIX of the Social Security Act to expand Medicaid coverage for certain individuals. It mandates that states provide Medicaid eligibility to individuals diagnosed with specific breast or cervical cancers, ensuring they receive necessary medical assistance. This change integrates these particular cancer patients into the program's mandatory eligibility groups. Furthermore, the legislation explicitly adds breast reconstruction following a medically necessary mastectomy to the list of covered medical assistance services under Medicaid. It also includes several technical and conforming amendments to federal matching funds and cost-sharing provisions, aligning them with the new eligibility requirements. The provisions of this Act will take effect one year after its enactment.
