The annual BNF version changes are due to be implemented with January 2021 dispensing data, planned publication of this data is around mid-March 2021.
The latest published mapping file shows the BNF presentation code as of December 2020 data against the BNF presentation code as of January 2021 data, also included is the BNF presentation name.
As ePACT2 always uses the latest BNF code, the BNF code as of January 2021 onwards will also apply to all historical data.
For any static reports, example monthly PCA data, English Prescribing Data (EDP) the BNF presentation code prior to January 2021 data will remain unchanged.
