Keeping Our Classification UP to Date.

In Australia, the National Centre for Classification in Health (NCCH) is ultimately responsible for updating ICD-10-AM disease codes and Australian Classification of Health Interventions (ACHI) procedure codes, and the accompanying Australian Coding Standards (ACS). New editions of these publications are released every two years. This article outlines the updating procedure and lists the sources of information upon which the NCCH draws when compiling data for new coding manuals.
