U.S. drug manufacturers are reaping a windfall from taxpayers because Medicare's privately administered prescription drug benefit program pays more than other government programs for the same medicines, according to a report from the House Committee on Oversight and Government Reform. The report found that taxpayers are paying up to 30% more for prescription drugs under Medicare's privatized Part D program for seniors and the disabled than under the government's Medicaid program for the poor. Committee Chairman Henry A. Waxman said he would introduce legislation to guarantee that federal taxpayers would not be charged higher prices under Medicare Part D than under Medicaid.
