The Office of Inspector General of the Department of Health and Human Services today issued a Special Fraud Alert pertaining to relationships between laboratories and referring physicians. Payments from labs to physicians who refer were targeted in the Alert. The Alert also reiterates their suspicion of so-called “carve out” compensation relationships where state and federal healthcare program dollars are removed from the payment formula (which was previously addressed last year in Advisory Opinion 13-03). While the Alert does not add anything new to the government’s view of such relationships, it does underscore the very suspect view the OIG has of payment relationships between labs and the physicians who refer to them. Careful compliance with the Personal Services and Management Contracts Safe Harbor continues to be a core concern.
