For those unfamiliar with the US health care system, Medicare’s hospital payment likely makes little sense. Medicare uses the prospective payment system to pay a hospital a fixed amount of money for a hospitalization: the Diagnosis Related Group (DRG) payment. The DRG payment covers all hospital-related expenses, except for physician services. For instance, the radiology technician who obtains the x-ray is paid under the DRG payment, but the radiologist who reads the x-ray is paid separately for each film read. The nurse who delivers a medication is paid under the DRG payment, but the physician who orders the medication is paid separately for each visit. Most private health plans mimic this fragmented payment method.
