ASCs

ASCs, or ambulatory surgery centers, are healthcare facilities that perform surgical, medical, or diagnostic procedures that do not require an overnight stay. They are designed to provide safe, efficient outpatient care and are distinct from hospital operating rooms and inpatient surgical units.

Procedures commonly performed in ASCs include cataract surgery, endoscopic gastrointestinal procedures, minor orthopedic, gynecologic, urologic, ENT, and plastic surgeries. Procedures are planned for same-day discharge, with postoperative instructions and follow-up arranged before the patient leaves.

In the United States, ASCs are regulated at both federal and state levels. Medicare and Medicaid enforce Conditions for Coverage for Ambulatory Surgical Centers, and facilities must be licensed by the state. Many ASCs pursue accreditation from bodies such as the Joint Commission, the Accreditation Association for Ambulatory Health Care (AAAHC), or DNV GL to obtain deemed status for Medicare payment.

Ownership varies: physician-owned practices, hospital-owned centers, and independent chains. The ASC model emphasizes streamlined scheduling, anesthesia services, and supply chain efficiency, which can reduce facility costs and support lower overall charges for eligible procedures.

Patient safety and quality are governed by clinical protocols, anesthesia oversight (often by physicians or certified nurse anesthetists), and a Quality Assessment and Performance Improvement program. Accrediting and regulatory requirements emphasize infection control, credentialing, equipment maintenance, and emergency preparedness.

Critics note that ASC suitability depends on patient selection and procedure complexity. Not all operations are appropriate for outpatient settings, and payer pricing and transparency remain ongoing concerns.
