Increasing SNOMED International description length limits
SNOMED International has confirmed the planned change to increase the maximum length of Fully Specified Name (FSN) and Synonym descriptions from 255 characters to 4,096 characters.
This change will be implemented in the 1 July 2026 International Edition release and will come into effect in the October 2026 UK Edition release.
See the news article on Delen for more information.
NHS England is seeking views from SNOMED CT users in the UK through a survey to help identify if additional information or support may be needed to prepare for the change, and to understand the most effective ways to communicate and share that information.
Your feedback will help NHS England decide whether further guidance or engagement is required to support users beyond that which SNOMED International is providing.
Please complete the survey by 5pm on Wednesday 10 December 2025.
If you have any issues completing the survey, contact: information.standards@nhs.net
