Next, following an approach validated in both academic and private practices [23,24] and used in recent studies [3,6,21,25,26], we used CMS POSPUF to classify radiologists as generalists or subspecialists. This approach classifies radiologists as subspecialists if greater than 50% of their reported work relative value units are clinical services associated with a specific subspecialty [23,24].…”

Radiologists whose primary group practice was not uniquely identifiable (eg, affiliation with multiple distinct practices or with multiple practice IDs that effectively compose a singular parent organization) were assigned to their largest practice by number of organization members.…”
