Freestanding Ambulatory Surgical and Emergency Centers
NAICS 621493 · United States · 2022 edition
This U.S. industry comprises establishments with physicians and other medical staff primarily engaged in (1) providing surgical services (e.g., orthoscopic and cataract surgery) on an outpatient basis or (2) providing emergency care services (e.g., setting broken bones, treating lacerations, or tending to patients suffering injuries as a result of accidents, trauma, or medical conditions necessitating immediate medical care) on an outpatient basis. Outpatient surgical establishments have specialized facilities, such as operating and recovery rooms, and specialized equipment, such as anesthetic or X-ray equipment.

For Freestanding Ambulatory Surgical and Emergency Centers, clarify the services, contracts and consequences of an error. Review medical professional liability, anesthesia liability, premises liability. Confirm which professional activities and additional services the proposed coverage actually addresses.
Questions to ask
- What types of surgical procedures are performed, and does the center perform any high-acuity specialties such as spine, cardiac, or bariatric surgery?
- Are operating physicians employed by the facility, independent contractors, or a mix — and do independent contractors carry their own professional liability coverage?
- Is there a formal credentialing and privileging program in place, and who oversees it?
- What is the annual patient encounter volume and procedure count?
- Does the center administer general anesthesia, regional anesthesia, or conscious sedation — and is anesthesia provided by employed CRNAs, physician anesthesiologists, or contracted groups?
- What is the facility's professional liability loss history for the past five years?
- Does the center own or lease the facility, and what is the replacement value of specialized surgical and diagnostic equipment?
- Are there any planned expansions, new service lines, or changes in ownership structure anticipated in the next policy period?

Freestanding ambulatory surgical and emergency centers provide outpatient surgical procedures and emergency or urgent medical care outside the traditional hospital setting. Day-to-day operations typically involve patient intake and triage, surgical or procedural suites staffed by physicians, nurses, and anesthesia providers, recovery and observation areas, and medical imaging or diagnostic equipment. Patients generally present, receive care, and are discharged the same day, though some centers provide short-duration observation stays.
