SNOMED CT-AU and Australian Medicines Terminology September 2023 Release

Published 27 September 2023

The National Clinical Terminology Service (NCTS) is pleased to announce that the September combined 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 bundle, reference sets) can be downloaded from the ACCESS tab.

First Release Candidate for AMT V4 now available for beta testing

The Australian Medicines Terminology (AMT) model has been revised with the AMT Working Group for closer integration with SNOMED International’s (SI) terminology dataset and to incorporate issues and ideas raised with AMT v3. Implementers are encouraged to be part of the SNOMED CT-AU beta testing commencing in September 2023 by providing feedback. The content and support document are available from the NCTS website. The content is also available in the Shrimp browser by selecting AU (Experimental) - Latest from the version dropdown menu. Please send questions or feedback to [email protected].

SNOMED CT International Release

The core Concept, Description and Relationship files have been updated to include the July 2023 International SNOMED CT Release. Consequently, all reference sets provided in the previous release have been updated accordingly. Specific content developments and improvements have been inherited from the July 2023 SNOMED CT International Release.
