Substantial differences in actual hourly and annual compensation exist across physician specialties, "with a number of specialties exhibiting compensation ratios exceeding 2:1 when compared to family medicine," according to "What if All Physician Services Were Paid Under the Medicare Fee Schedule? An Analysis Using Medical Group Management Association Data," a new report sponsored by the Medicare Payment Advisory Commission (MedPAC). The study, conducted by staff from the Urban Institute and the Medical Group Management Association Center for Research, simulated physician compensation as if all physician services were paid under the Medicare Part B Physician Fee Schedule and compared the results with the actual physician-reported compensation.
