The main purpose of the Rural Health Care Access Act of 2025 is to improve access to healthcare in rural areas by allowing states to designate facilities as critical access hospitals without being restricted by mileage limitations. This aims to ensure that more rural healthcare facilities can qualify for federal support, thereby enhancing healthcare services for residents in these areas. Key provisions of the Act include the amendment of the Social Security Act to remove the mileage restrictions that previously limited which facilities could be designated as critical access hospitals.
