(AREA) -- Federal authorities say a suburban Detroit doctor has been charged with fraud in a scheme to milk millions from the Medicare program for unnecessary cancer treatments. A criminal complaint filed Tuesday says Dr. Farid Fata ordered chemotherapy for patients in remission and deliberately misdiagnosed patients as having cancer. In one case, the government says a patient fell and hit his head at Fata's clinic but was told he needed chemotherapy before he could be taken to a hospital. The man later died. Defense attorney Christopher Andreoff says the allegations are from co-workers. He says it's premature to allege that Fata harmed anybody. Fata is in jail awaiting another court hearing Thursday. Fata owns Michigan Hematology Oncology Centers, with offices in Clarkston, Bloomfield Hills, Lapeer, Sterling Heights, Troy and Oak Park.
