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 Switzerland Extension - packages these components for release every December and July, to be used with the latest SNOMED CT International Edition release.

The same content can be viewed online using the SNOMED CT browser.

Background

This document provides a summarized description of the content changes included in the June 2025 Production release of the SNOMED Clinical Terms^® Managed Service Switzerland 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 Switzerland Extension package is dependent upon, and should therefore be consumed in conjunction with, the SNOMED CT® May 2025 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.
