BNF SNOMED mapping

We publish BNF / SNOMED mapping data.

One Drug Database (ODD) has been implemented. As the data has now moved to the new format, we have updated the BNF SNOMED mapping file to reflect this. The 'MDR: Product Description' has been replaced with the new naming convention, 'BNF Description'.

The dataset shows one row for every VMP / AMP / VMPP / AMPP record and a field showing which BNF code this maps to.

The data published in February 2024 contains information relating to December 2023. 

How often we'll publish data

Data is published monthly and will relate to the latest available month in ePACT2 at the time of publication. For example, data published by the end of January 2024 contains records of a full mapping based on what was populated on our drug database as of November 2023, regardless of whether there has been any prescribing or not.

BNF / SNOMED guidance document (Word: 246KB)

Please note: It has been identified that the BNF Name populated in the January 2023 and February 2023 mapping file has been restricted to a maximum of 20 characters instead of the normal maximum 60-character drug limit and 100-character appliance limit.

We have re-run these two files and replaced the current published files for these two months.

We apologise for any inconvenience this may have caused.

There will be one other noticeable difference in these two files and in future months going forward where a significant number of VMP appliance products will no longer be populated with a BNF Code. These appliances are only listed as AMP products in Part IX of the Drug Tariff, therefore the BNF Code has been removed accordingly.
