The LARC Access Expansion Act would authorize federal grants to eligible health centers to expand access to long-acting reversible contraception, such as IUDs and implants. Health centers receiving grants must serve areas with high rates of infant or maternal mortality, medically underserved populations, or health professional shortage areas, and cannot currently receive federal family planning funds under Title X. Funded health centers would use the grants to train staff on contraception provision and maintain inventory for same-day insertion, with a separate demonstration program allowing some centers to use telehealth to increase contraceptive access, particularly in rural areas. All grant recipients must certify they will not perform abortions or fund entities that do. The legislation does not specify funding amounts or implementation timelines in the text provided.
