Overview
Multispecialty & Primary Care Groups covers primary-care medical groups, FQHCs, concierge practices, and multispecialty clinics — the front door of the healthcare system. It is the core of the physician-office market and the focus of an intense battle for primary care among payers, retailers, and value-based-care platforms.
Payers and others have invested heavily to own or align primary care (Optum, Amazon/One Medical, CVS/Oak Street Health, agilon, Privia), drawn by its role in steering care and bearing risk in value-based models. The federal data category captures all physician offices, of which primary and multispecialty groups are the largest share.

It is 90% small practices, which is exactly why PE platforms and health systems have rolled up specialty after specialty; primary and multispecialty groups are the largest share.
