Most states reported adding one or two ASCs from June 2016 to July 2017, but not all, according to ASCA's analysis of data on Medicare-certified ASCs provided by CMS. At least three states had fewer ASCs in 2017 than in 2016.
The three states that lost the most ASCs were:
1. Tennessee: 6
2. Oregon: 4
3. South Carolina: 4
All three states have a certificate-of-need program in place, although legislators in South Carolina have made attempts over the past few years to change their policy. California, Texas and Georgia gained the most ASCs over the past year, with California adding 26 centers. Two of the three states with the biggest gains — California and Texas — do not have CON programs in place.
