Number of ambulatory surgery centers: In 2009, there were a total of 5,260 Medicare-certified ambulatory surgery centers in the U.S., up from 4,106 five years earlier, according to data from the Centers for Medicare and Medicaid Services (CMS). However, the year-to-year net growth rate in the total number of ASCs has been steadily slowing, from nearly 8 percent in 2004 to about 2 percent in 2009. Partial data for 2010 (through the first three quarters) show a count of 5,291 ASCs, and a growth rate slowed even further — to 0.6 percent – which is attributed to the recession and to changes in ASC reimbursement that were introduced in 2008. Number of operating rooms in ASCs: The source reports that there are an average of 2.6 ORs per ambulatory surgery center which, according to my calculations, would be nearly 13,700 ORs in ASCs in 2009. Other characteristics of ASCs: Over 85 percent of Medicare-certified ASCs are in urban areas and virtually all (96 percent) are for-profit. Some states have a higher concentration of ASCs than others — the top states include Arizona, Washington, Idaho, and Maryland. Migration of procedures from hospitals: This report contains an interesting analysis of the utilization of procedures in the (mostly freestanding) ASCs compared to hospital outpatient departments, noting a higher overall five-year growth rate for the ASCs in services provided and number of Medicare patients served.
