Addition of Trade Family and Trade Family Group to dm+d

As of Monday 6 July 2026, NHSBSA maintains and supports the Trade Family and Trade Family Group concept classes within the dm+d supplementary extract files.

NHSBSA dm+d supplementary release 7.0.0 is the first to include Trade Family and Trade Family Group data.

The NHS dm+d browser and the NHS England Terminology Server now include Trade Family and Trade Family Group data.

NHS England dm+d Refset data includes Trade Family and Trade Family Group data from Monday 6 July 2026.

Historical inactive Trade Family and Trade Family Group data created within the SNOMED CT UK Drug Extension before this data was introduced to dm+d in July 2026 has not been migrated into dm+d. The first dm+d release containing the data establishes the baseline for future maintenance and publication of the data. If you need information on Trade Family and Trade Family Group data inactivated before July 2026, refer to the SNOMED CT UK Drug Extension releases.

At launch, Trade Family and Trade Family Group data is current up to and including 26 June 2026. During the initial implementation period, Trade Family and Trade Family Group data will not be refreshed on the same weekly schedule as the core dm+d release. As a result, newly created or updated AMPs may not immediately reflect the latest Trade Family or Trade Family Group assignments.

This is the first publication of Trade Family and Trade Family Group data within dm+d. The data is live and available for use, but will continue to be reviewed as part of routine maintenance.

Email any issues with the data, questions or feedback to dmdenquiries@nhsbsa.nhs.uk.

These descriptions will first appear in the SNOMED CT UK Edition release 43.0.0, due for publication on 30 September 2026 (see the 2026-2027 Release Schedule: SNOMED CT UK Edition page on Delen), as that release will include data from the August 2026 SNOMED CT International Edition.
