The diagnosis array comprises data elements that provide information on the conditions reported to the admitted patient care data sets. Diagnosis cluster coding is a method that links related International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) codes together, evidenced by clinical documentation in the patient’s health care record. The diagnosis cluster identifier (DCID) is recorded against all ICD-10-AM codes assigned to an episode of admitted patient care. Where two or more ICD-10-AM codes are assigned the same DCID value, these codes are considered to be 'clustered' and are related to one another. Reporting the diagnosis array is not contingent upon a system's ability to report the DCID for episodes of admitted care on and from 1 July 2025. Until the DCID is implemented in local systems, supplementary value 9 can be reported. |
