The following data table lists the top 25 physician groups by procedure volume. According to 2019 commercial claims data, physician groups have performed a total of nearly 530 million procedures this year. Though the procedures were shared between the 93,662 different physician groups that Definitive Healthcare tracks, the top 25 groups carried out 53.5 million of these procedures—accounting for 10 percent of the overall total for the 2019 claims year. The top physician group by procedure volume is Clinical Pathology Associates (Austin, TX), with a total of almost 10 million procedures this year. 

Clinical Pathology Associates reports one of the lowest average costs per procedure of the facili­ties listed. With an average cost per procedure of $845, Texas Oncology (Dallas, TX) has the highest average cost and the greatest number of total charges—despite ranking 8th on this list by procedure volume.

The regional distribution of these top 25 physician groups is almost evenly spread between states in the southern, midwestern, and northeastern regions—with about one-third of the physician groups located in primarily southern states. State size and patient concentration are most likely factors in the increased procedure volume that we see in these regions.

The top 25 physician groups yield just over $11 billion in combined total charges, with an overall aver­age cost of $241 per procedure.

A year-over-year comparison shows that combined total charges for the top groups has decreased by about $4 billion in recent years—down from a combined total of $15.3 billion in 2017. Though total charges have gradually decreased, there has been no significant change in average cost per proce­dure from year to year.
