Using pseudo BNF codes with the codelist_from_csv function

[SRW612]

Just a very small question about the codelist_from_csv function: if I am using this to import pseudo BNF codes, what do I put for the 'system=' option? The documentation mentions system="snomed" and system="ctv3" but I can't find the equivalent for pseudo BNF anywhere.

On OpenCodelists we make pseudoBNF available as there is a good human structured hierarchy which makes it easy to build codelists. However you'll need to use a NHS dictionary of medicines and devices dm+d codelists to query using with_these_medications.

dm+d is effectively a local UK snomed extension and we have plenty available on opencodelists. If you have made a new pseudoBNF list we can help convert it to dm+d if you can share the url?

Thanks for the explanation of dm+d. I just tried downloading the dm+d version of my codelist, then using that to create a new snomed-based codelist, although the codes are mainly unknown and I am stopped at the csv upload stage.

I have already created a pseudo BNF codelist, if you are able to help convert it:
