One of twenty-three mutually exclusive principal diagnostic categories, that correspond to a single organ system or aetiology. In general these are associated with a particular medical specialty. An additional two categories address exceptions (pre-MDCs) and errors. They are derived from the DRG code.
Institutional health care: The development of Australian Refined DRGs has created a descriptive framework for studying hospitalisation. DRGs provide a summary of the varied reasons for hospitalisation and the complexity of cases a hospital treats. Moreover, as a framework for describing the products of a hospital (that is, patients receiving services), they allow meaningful comparisons of hospitals' efficiency and effectiveness under alternative systems of health care provision.
