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 May 2021 release of the SNOMED Clinical Terms® Managed Service Sweden Extension package.
It will 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 Sweden Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® July 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.
3 Content Development Activity

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 - Sweden Extension November 2021, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:
4.2 Technical notes
Promoted concepts
Some concepts from the Swedish extension have been promoted to the international release (900000000000207008 | SNOMED CT core module (core metadata concept) |). The concepts have been added to the international release files with an effectiveTime which supersedes the latest effectiveTime in the Swedish extension release files. The concepts will be retained in the Swedish extension snapshot files in perpetuity as per SNOMED International recommendations and anyone using these files will have to manage the possibility of duplicated ids (with different effectiveTime) across release files. The risk of issues can be mitigated by filtering to only use Swedish extension records with effectiveTime:s greater than their International counterparts. Links to relevant documentation will be added to these release notes once that documentation has been updated.
The promoted concepts in the November 2021 release are:
- 62461000052109 | Second transurethral resection of bladder (procedure) |
- 65971000052100 | Acute psychosis (disorder) |
- 69621000052107 | Flexible bronchoscopy (procedure) |
- 70711000052105 | Assessment of bone age using Tanner-Whitehouse 2 method (procedure) |
- 70721000052102 | Assessment of bone age using Tanner-Whitehouse 2 radius-ulna-short bones method (procedure) |
- 70731000052100 | Assessment of bone age using Tanner-Whitehouse 3 method (procedure) |
