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 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 951Z, 955Z and 956Z 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 principal diagnosis. Diagnosis codes which are morphology codes cannot be used as principal diagnosis. |
---|---|
Collection methods: | A principal diagnosis should be recorded and coded upon separation, for each episode of patient care. 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. |
