BNF / SNOMED mapping data is published by the NHS Business Services Authority (NHS BSA) and represents mapped data between the Dictionary of Medicines and Devices (dm+d) and the legacy Master Data Replacement (MDR) drug database.

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 July 2019 contains information relating to May 2019. NHS BSA will publish refreshed data on a monthly basis with the data relating to the latest available dispensing months data in ePACT2 at the time of publication. For example, data published by the end of July 2019 containing data relating to May 2019 dispensed prescriptions.
