Definition: | Major diagnostic categories (MDCs) are 23 mutually exclusive categories into which all possible principal diagnoses fall. The diagnoses in each category correspond to a single body system or aetiology, broadly reflecting the speciality providing care. Each category is partitioned according to whether or not a surgical procedure was performed. This preliminary partitioning into major diagnostic categories occurs before a diagnosis related group is assigned. The Australian refined diagnosis related groups (AR-DRGs) departs from the use of principal diagnosis as the initial variable in the assignment of some groups. A hierarchy of all exceptions to the principal diagnosis-based assignment to a MDC has been created. As a consequence, certain AR-DRGs are not unique to a MDC. This requires both a MDC and an AR-DRG to be generated per patient. |
Context: | All admitted patient care contexts: The generation of a major diagnostic category to accompany each AR-DRG is a requirement of the latter as diagnosis related groups are not unique. |

Comments: | This metadata item has been created to reflect the development of Australian refined diagnosis related groups (AR-DRGs) (as defined in the metadata item Episode of admitted patient care—diagnosis related group, code (AR-DRG v 8.0) ANNA) by the Commonwealth Department of Health. Due to the modifications in the diagnosis related group logic for the AR-DRGs, it is necessary to generate the major diagnostic category to accompany each diagnosis related group. The construction of the pre-major diagnostic category logic means diagnosis related groups are no longer unique. Certain pre-major diagnostic category diagnosis related groups may occur in more than one of the 23 major diagnostic categories. |
