Aligning the SNOMED CT UK Drug Extension model with SNOMED International
NHS England has added more detail and examples to its Updating the SNOMED CT UK Drug Extension model page. This follows feedback from the recent user survey.
The plan is to:
- release a test file with the Phase 1 changes for SNOMED CT UK Drug Extension users in July 2025
- go live with the Phase 1 changes in the SNOMED CT UK Drug Extension in September 2025
If the September timeframe is likely to cause issues, or if you would like to discuss this work, contact: nhsdigital.ukmeds@nhs.net
