This bill, known as the Rural Health Sustainability Act of 2025, seeks to modify the criteria for designating rural emergency hospitals under Title XVIII of the Social Security Act. The legislation amends Section 1861(kkk)(3) to update the historical reference date for eligibility from the original enactment date to January 1, 2014 . Additionally, the bill introduces a new criterion for designation, allowing facilities to qualify if they "was designated as rural by the Office of Rural Health Policy of the Health Resources and Services Administration." These changes aim to broaden the scope of facilities eligible for rural emergency hospital status, potentially supporting healthcare access in rural communities.
