More and more physicians who used to accept on call duty at a hospital as part of their obligations of being part of the medical staff are insisting on receiving some form of remuneration for the inconvenience. On October 30, 2012 the Office of Inspector General of HHS posted an advisory opinion No. 12-15 approving a hospital’s plan to pay for on-call services of physicians on its medical staff. These are for consulting physicians, not those physicians called on a regular basis to assist the ER, like intensivists, hospitalists, interventional cardiologists, etc. The concern of the OIG was the likely implication of the federal antikickback statute. The personal services and management contracts safe harbor at 42 CFR Section 1001.952(d) doesn’t apply because it requires the aggregate amount of compensation to be identified in advance.
