A code which signifies the patient's classification in the hospitals case mix, derived from the ICD-10-AM diagnostic codes for principal and secondary diagnoses, procedures performed, age, sex and discharge status.
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.
