Page At A Glance

1. Introduction

SNOMED CT terminology provides a common language that enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care.

The International Health Terminology Standards Development organisation (IHTSDO®), trading as SNOMED International, maintains the SNOMED CT technical design, the content architecture, the SNOMED CT content (includes the concepts table, the descriptions table, the relationships table, a history table, and ICD mappings), and related technical documentation.

2. Background

This document provides a summarized description of the content changes included in the April 2019 Production release of the SNOMED Clinical Terms® Managed Service New Zealand Extension package.

It will also include technical notes detailing the known issues which have been identified (should any of these exist). These are content or technical issues where the root cause is understood, and the fix has been discussed and agreed, but has yet to be implemented.

This New Zealand Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® July 2019 International Edition release.

This New Zealand Extension BETA release package is for information/evaluation purposes ONLY, and may NOT in any way be used for Production clinical purposes.

2.1. Scope

This document is written for the purpose described above and is not intended to provide details of the technical specifications for SNOMED CT or encompass every change made during the release.

3. Content Development Activity

3.1. Summary

Content from the SNOMED CT® July 2019 International Edition release has been incremented, using additional components for use in New Zealand. 

This extension contains concepts, relationships and reference sets for healthcare professionals. 

3.2. New and Updated Content

There are 38 New Zealand concepts included in this release.

4. Technical notes

4.1. Known Issues

Known Issues are content or technical issues where the root cause is understood, and the resolution has been discussed and agreed but has yet to be implemented.  This can be due to a number of reasons, from lack of capacity within the current editing cycle, to the risk of impact to the stability of SNOMED CT if the fix were to be deployed at that stage in the Product lifecycle.  

For the SNOMED CT Managed Service - New Zealand Extension Release, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:
