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 March 2021 Production release of the SNOMED Clinical Terms® Managed Service Belgium Extension package.
It also includes 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 Belgium Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® January 2021 International Edition release.
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.

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.

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:
