Aligning the SNOMED CT UK Drug Extension model with SNOMED International
Following the phase 1 changes implemented in October 2025, NHS England is now progressing with the phase 2 changes.
The NHS England web page on aligning dm+d VMPP class medicinal products to the SNOMED International drug model has been updated with information about the changes, including examples and diagrams to help explain them.
Test files with the phase 2 changes to the SNOMED CT UK Drug Extension are available on Delen.
The changes are planned to be implemented in the first quarter of 2026.
In preparation, NHS England is asking SNOMED CT UK Drug Extension users to complete a survey so they can understand the effect the changes may have. Your feedback will help NHS England work with you to implement these changes.
Please submit your survey response by 5pm Friday 28 November 2025.
If you have any issues completing the survey or would like to discuss this work further, contact: nhsdigital.ukmeds@nhs.net
