The change can be an addition, deletion or amendment. Where an amendment has been made, this will show the first original line and then the replacement line e.g. Crinx bandage 10cm x 3.5m amended to read Crinx bandage 10cm x 4m."

Additionally, caveat for BNF Categorisation and Structure updated to include extra details: "New BNF codes are created as needed, but changes to existing BNF codes occur once a year as part of the BNF version update. For example, if a product moves from Chapter 03 to Chapter 04, this change takes effect in January. Version changes appear in the change report, with the previous BNF chapter/section etc listed under Remove and the updated BNF chapter/section etc listed under Add."

As we move through the new calendar year, you will see some movement in the information held in the BNF datasets.

The December file published in January 2026 is the final version of the 2025 changes file and displays all changes that were made from March to December - (Future editions will provide a complete view of January to December).

The January monthly changes file published in February coincides with the launch of the new BNF version 90 BNF Code Information - Current Year Dataset and displays the latest changes that have been introduced to the new BNF version 90.
