Quick Answer
Ambulatory surgery centers offer the same procedures as hospital outpatient departments at 40-60% lower cost. Theyre ideal for healthy patients having routine procedures. Hospitals are better for complex cases, high-risk patients, or procedures that might need overnight stays.
What is an Ambulatory Surgery Center?
An ambulatory surgery center (ASC) is a healthcare facility focused exclusively on same-day surgical procedures. Unlike hospitals, ASCs dont have emergency rooms, overnight beds, or the overhead of running a full-service hospital. This specialization allows them to offer lower prices and often faster, more personalized care.
ASCs perform the same procedures as hospital outpatient departments, using the same surgeons and meeting the same safety standards. Medicare and most insurance companies cover procedures at ASCs the same as hospitals - but your out-of-pocket cost is often lower due to the facilitys lower fees.

Real Cost Differences (Illinois Examples)
Prices shown are typical facility fees. Surgeon and anesthesia fees are usually the same regardless of setting.
Are Surgery Centers Safe?
Yes - Often Safer for Appropriate Procedures
Research shows ASCs have lower infection rates than hospitals, partly because they treat healthier patients and dont have the bacterial exposure found in hospitals. ASCs must meet strict Medicare certification standards and undergo regular inspections.
- Medicare-certified ASCs meet same safety standards as hospitals
- Surgeons are the same physicians who operate at hospitals
- Transfer agreements with nearby hospitals for emergencies
- Complication rates are low (about 0.5% need hospital transfer)
