Table Of Contents
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.
The SNOMED CT Irish Extension - packages these components for release every April and October, to be used with the latest SNOMED CT International Edition release.
The same content can be viewed online using the SNOMED CT browser, and eHealth Ireland website
Background
This document provides a summarized description of the content changes included in the January 2026 Production release of the SNOMED Clinical Terms® Managed Service Ireland 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 Ireland Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® January 2026 International Edition release.
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.

IE National Drug Extension
Medicinal product content includes development across the SNOMED International Drug Model and the Irish Drug Extension Model. The National Drug Extension continues to be developed.

Technical notes
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.
The following known issues were identified:
Resolved Issues
Resolved Issues are those where the resolution has been discussed and agreed, and has been implemented in time for this release.
Changes since October 2025
Monthly Releases
The NRC has moved to monthly releases since October 2025, this January release is the third of these monthly releases.
Refset File Naming conventions
The new naming conventions for additional reference sets files have been applied to the Ireland Extension release package from the October 2025 IE Managed Service Release onwards. The new convention updates the file names to use RefsetID prefixes instead of the old human readable format, in order to improve maintainability and allow for machine reading of the file names. However, this convention will ONLY be applied to additional refsets, and not core refsets such as Language refset, Association refset, MRCM refset files, etc. (as these were considered to incur too high an impact on end users if the naming conventions were to be changed)
So, for example, in the October 2025 IE Managed Service Release the additional refset file names have changed from:
“der2_Refset_AntimicrobialStewardshipPerformanceIndicatorMeasurementSystemApimsDataSetSimpleRefsetFull_IE1000220_20250421.txt”
to:
“der2_Refset_74921000220101SimpleRefsetFull_IE1000220_20250421.txt”
The file name of the Association reference set has been aligned with the naming convention used in the International Edition. Please refer to the Terminology Release Advisory Group discussion page for details: Association Reference naming convention
“der2_cRefset_AssociationReferenceFull_IE1000220_20250421.txt”
to:
“der2_cRefset_AssociationFull_IE1000220_20250421.txt”
