Ambulatory surgery center (ASC)
An ambulatory surgery center (ASC) is a health care facility that specializes in providing surgery, pain management, and certain diagnostic services in an outpatient setting. ASC-qualified procedures are typically more complex than those done in a doctor’s office but not so complex as to require an overnight stay. Procedures commonly performed in these centers include colonoscopies, endoscopies, cataract surgery, orthopedic, and ENT (ear, nose, and throat) procedures. An ASC may also be known as an outpatient surgery center or same-day surgery center.
