International Statistical Classification of Diseases and Related Health Problems

Australia uses the International Statistical Classification of Diseases and Related Health Problems (ICD) to code causes of death (WHO 2019).

In this report, deaths were coded using the Tenth Revision of the ICD (ICD-10) (Table 1).

For hospital diagnoses, a classification modified for Australia, the ICD-10-AM (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification) was used.

Diagnosis data for 2019–20 were reported to the National Hospital Morbidity Database using the 11th edition of the ICD-10-AM (ACCD 2018) (Table 1).
