ICD-10 to ICD-10-AM

Demonstrates the relationship between the codes in the World Health Organization’s ICD-10 and the Australian Modification of ICD-10 (ICD-10-AM).

The maps describe a directional relationship between a classification where the data is recorded in (the source classification) to the classification the data needs to be reported in (the target classification). The relationship between two classification systems is described using one of two possible types of maps:

• One-to-one. This type of map is used where a code from the source classification is only linked with one code from the target classification.
• One-to-many. This type of map is used where a code from the source classification is linked with more than one code from the target classification, which may be of different types. Where a code has a one-to-many relationship, a new row is used to demonstrate this relationship. The source classification code is repeated against different target classification codes.

Use Case & Benefit
Useful when Australian health data is recorded in ICD-10-AM but needs to be reported in ICD‑10, compared internationally or when determining the comparability of the classifications. These mapping tables provide an insight into the enhancements made for ICD-10-AM.
