Improving Care in Rural America Reauthorization Act of 2025 This bill reauthorizes through FY2030 grant programs administered by the Health Resources and Services Administration (HRSA) that provide funding to health care service providers and related entities in rural areas. Specifically, the bill reauthorizes grants for expanding the delivery of health care services in rural areas, developing integrated health care networks (i.e., collaborative groups of local health care organizations) in rural areas, and improving the quality of services provided by small health care providers in rural areas. Also, the bill requires HRSA to ensure that grant funds for expanding services or developing health care networks are used to (1) meet the health care needs of underserved populations, and (2) engage such populations in the planning and implementation of related activities.
