Ambulatory surgery centers are independent facilities focused exclusively on outpatient surgery. Compared to hospital outpatient departments, ASCs typically have lower patient cost-sharing (due to CMS payment rules), shorter wait times, and a more focused care environment. Studies show ASC patients also report high satisfaction and low complication rates.
