Physicians who reassign their right to bill the Medicare program can still be liable for false claims submitted by the entities who obtained that reassignment, as discussed in a recent "Alert" issued by the Office of Inspector General (OIG). [PDF].
OIG also referenced settlements it reached with eight physicians who had reassigned their payments to physical medicine companies in exchange for Medical Directorship positions -- when those companies subsequently billed Medicare for services that the physicians had not actually performed.
This OIG Alert highlights the ability of physicians to monitor all services billed using their reassigned provider numbers, and strongly urges physicians to do so. If not, physicians face liability for false claims asserted under their provider numbers.
