| Guide for use: | The principal diagnosis must be determined in accordance with the Australian Coding Standards. Each episode of admitted patient care must have a principal diagnosis and may have additional diagnoses. The diagnosis can include a disease, condition, injury, poisoning, sign, symptom, abnormal finding, complaint, or other factor influencing health status. As a minimum requirement the Principal diagnosis code must be a valid code from the current edition of the International statistical classification of diseases and related health problems, 10th revision, Australian modification (ICD-10-AM). For episodes of admitted patient care, some diagnosis codes are too imprecise or inappropriate to be acceptable as a principal diagnosis and will group to an error DRG in the Australian Refined Diagnosis Related Groups. Diagnosis codes starting with a V, W, X or Y, describing the circumstances that cause an injury, rather than the nature of the injury, cannot be used as a principal diagnosis. Diagnosis codes which are morphology codes cannot be used as a principal diagnosis. | ||||||||||||||||||||||||||||||||||||||||||||
| Collection methods: | A principal diagnosis should be recorded and coded upon separation, for each episode of admitted patient care or episode of residential care or attendance at a health-care establishment. The principal diagnosis is derived from and must be substantiated by clinical documentation. | ||||||||||||||||||||||||||||||||||||||||||||
| Comments: | The principal diagnosis is one of the most valuable health data elements. It is used for epidemiological research, casemix studies and planning purposes. | ||||||||||||||||||||||||||||||||||||||||||||
