2026-02-06 Description for CHANGE_TYPE changed to ''This outlines the type of change that has occurred compared with the previously published current file. A change may be an addition, deletion, or amendment. Where an amendment has been made, the report will display the original line followed by the revised line; for example, Crinx bandage 10cm x 3.5m amended to Crinx bandage 10cm x 4m. Annual version changes, implemented in January, include instances where a product is reassigned to a different BNF chapter, BNF section etc. In these cases, the previous BNF chapter/ section etc will appear under Remove, and the updated chapter or section will appear under Add.'' from ''This provides the type of change that has happened from the previously published current file. 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."
