California’s Attorney General has secured another enforcement settlement targeting corporate practice of medicine violations, this time directing Carbon Health to unwind key elements of its business structure.
The action requires Carbon Health to restructure core elements of its friendly-PC model, marking a significant development in the state’s ongoing scrutiny of MSO and physician-corporation arrangements.
The settlement follows the same pattern established in the earlier ADMI matter, signalling that the Attorney General is conducting a deliberate enforcement campaign against certain MSO and PC structures.
Authorities allege those structures cross a legal line by giving management organisations too much operational control over medical practice decisions that should remain with licensed physicians.
The complaint identified a series of unusually direct control rights held by the MSO at the centre of the arrangement, raising concerns about the true independence of the affiliated physician group.
Those rights reportedly included MSO authority over physician hiring and firing, which regulators considered a fundamental breach of proper medical practice governance.
The complaint also pointed to assignable ownership and option rights within the structure, alongside exclusive above-market financing arrangements that left the physician corporation financially dependent on the MSO.
Contractual terms that dictated staffing, scheduling, and other day-to-day operational decisions were also cited as evidence that the MSO had assumed impermissible control over the practice.
Despite the firmness of the enforcement action, the settlement reinforces an important nuance in how California regulators are approaching this area of healthcare law.
The Attorney General’s most aggressive remedies still appear reserved for arrangements where both the documents and actual operations demonstrate meaningful MSO control over the practice, rather than the typical friendly-PC model.
MSO-supported healthcare platforms across California should expect continued regulatory scrutiny of their governance structures, financing arrangements, and the extent of operational control exercised over affiliated physician practices.
The Carbon Health settlement adds to a growing body of enforcement actions that are reshaping how management services organisations structure their relationships with physician groups in the state.
