An ASC must be certified and approved to enter into a written agreement with CMS. Participation as an ASC is limited to any distinct entity that operates exclusively for purposes of providing surgical services to patients not requiring hospitalization (i.e., an inpatient stay in a hospital).

ACHC has deeming authority to accredit ASCs. This program’s requirements incorporate the CMS Conditions for Coverage (CfC) along with other patient safety and quality related standards.
