During the fall of 2016, the Centers for Medicare & Medicaid Services (CMS) released a final rule titled Emergency Preparedness Requirements for Medicare and Medicaid Participating Providers and Suppliers. The regulation became effective on November 16, 2016, and as of November 15, 2017, the 17 health care provider and supplier types that must comply with the rule, including ASCs, began being held to these revised standards during their Medicare surveys.
