Ambulatory Surgery Center Facts
Ambulatory surgery centers (ASCs) are an integral and well-established part of our nation's healthcare system.
- An ambulatory surgery center is a healthcare facility that performs outpatient surgical procedures for patients who do not require an overnight stay.
- Texas surgery centers are licensed by the Texas Department of State Health Services and most are also Medicare certified.
- The first U.S. surgery center opened in 1970, and today, there are over 5,900 Medicare-certified ambulatory surgery centers in the United States, performing 22.5 million surgical procedures annually (via Ambulatory Surgery Center Association).
-
Almost 75% of all surgery today is performed on an outpatient basis. In 1980, that figure was only 15%. Slightly more than half of all outpatient surgeries are done in an ambulatory surgery center.
