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 organization (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.
We kindly encourage all Belgian users to submit their feedback on the content of the Belgian Edition through the NRC's Request Management Portal.
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 Belgium Edition package.
It also includes technical notes detailing the potential known issues. 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.

SNOMED CT derived products
Reference sets
The release currently contains reference sets that serve one of the following 2 purposes :
- Reference sets to support the implementation of SNOMED CT in eHR software for clinical data entry/capture. These reference sets have a six-monthly release cycle.
- Reference sets to support data interoperability (mainly subsets representing value lists of BE FHIR profiles required by the Care Sets). These reference sets have a monthly release cycle.
A new version of a reference set is only published when there is a change compared to the previous version. Reference sets that do not require an update (meaning having no delta) are not republished despite their release cycle.
Here is a summary of the different existing refsets and their purpose:
Purpose | Subset | SCTID | Content |
Clinical data entry | Belgian subset for medical problems in patient health records refset | 40811000172108 | Common disorders, findings and procedures found in general patient records. |

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.
For the SNOMED CT Managed Service - Belgium Extension Release, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:
Technical notes
Notice of changes to the Belgium Edition Release Schedule
As you may already know SNOMED International has transitioned to a monthly delivery schedule for the International Edition of SNOMED CT. The move towards more frequent releases of SNOMED CT has several benefits, including:
- Inclusion of suggested changes in a shorter timeframe.
- Better interoperability, as a result of entities being able to consume release content that is more aligned with other organizations.
- The prevention of circular dependencies that occur in longer projects, due to the move towards smaller, more manageable authoring projects.
- More automated validation services, as a result of the inherent removal of the Alpha/Beta stages in the Release cycle.
Whilst most users will continue unaffected (as they can simply continue to download the releases every 6 months as always), this transition will necessarily involve a few changes to process/packages:
- Delta files have been removed from both International and Managed Service release packages, including the Belgium Extension. A Delta Generation service will be provided for those who need it. The Delta Generation Tool allows users to create their own Delta between two fixed release dates - you can find it here:
- The ICD-O/ICD-10 Maps will continue to be published in each Monthly International Edition release package (in line with that month's content) for the foreseeable future, unless we experience issues with the new process in Production, and they need to be removed at a later date.
The Belgian edition of SNOMED CT is also released monthly on the 15th of each month, except for January and August. The first monthly Belgian edition was published in November 2024.
Notice of changes to the BE Edition Release package
In line with the refined implementation of Annotations, we are updating all Extensions in order to align them with the updated version of the refsets in the International Edition Release package (which were first published in June 2024).
- The languageCode field was specified as the two characters of ISO|-639-1 code for the language of the annotation text. The change includes support for specifying dialect when it is applicable by adhering to RFC 5646, which allows the combination of two characters of ISO 639-1 code and two uppercase letters of country code (ISO 3166) separated by a hyphen. The changes apply to both the Member Annotations String Value Reference Set + Component Annotation String Value reference set:
- The column "languageCode" has therefore been changed to "languageDialectCode".
- Component Annotations (1292992004)
- OLD: id effectiveTime active moduleId refsetId referencedComponentId languageCode typeId value
- NEW: id effectiveTime active moduleId refsetId referencedComponentId languageDialectCode typeId value
- Member Annotations (1292995002)
- OLD: id effectiveTime active moduleId refsetId referencedComponentId referencedMemberId languageCode typeId value
- NEW: id effectiveTime active moduleId refsetId referencedComponentId referencedMemberId languageDialectCode typeId value
- Component Annotations (1292992004)
- The column "languageCode" has therefore been changed to "languageDialectCode".
