SNOMED CT-AU and Australian Medicines Terminology January 2022 Release

Published 24 January 2022

The National Clinical Terminology Service (NCTS) is pleased to announce that the January release of SNOMED CT®‑AU[1] and the Australian Medicines Terminology (AMT) is now available to registered users from the NCTS website. 

The latest Release Note and all release files (RF2 bundlereference sets) can be downloaded from the ACCESS tab.

Important Information

SNOMED CT-AU Change Reports, CSV

Two new custom CSV files were released in October. They contain the concept changes (deltas) between the latest SNOMED CT-AU release and the one prior in an easy to use human readable format. These files can assist organisations in their terminology maintenance or updates.

The Concept Changes CSV File lists new and retired concepts, along with their preferred terms. The Associations CSV File lists retired or changed concepts (along with their preferred terms), reasons for the change, and suggested replacements.

Both files include the SNOMED CT-AU and Australian Medicines Terminology modules, which can be used to filter content as required.

Note: if there are no changes for the month, only the header row will appear in the file. 

You can access these files from the Other section of the NCTS website’s Access tab, after logging in. Please contact the NCTS should you require further information.
