Aligning the SNOMED CT UK Drug Extension model with SNOMED International
NHS England posted an update on Delen in December 2025 about the planned phase 3 and phase 4 changes to the SNOMED CT UK Drug Extension. NHS England asked for feedback on its plan to publish the changes as a single, combined release. It did not receive any concerns by 15 January 2026, so it will proceed with this approach.
To help NHS England understand the impact of these changes, it plans to publish a survey in March 2026 with test files. This will let you review the phase 3 and phase 4 changes and provide feedback.
For more information, see NHS England's updating the SNOMED CT UK Drug Extension model page.
