The FHIR site suggests using SNOMED valuesets for these fields but on most systems I’ve encountered they’ve been English Specialty codes (believe Scotland uses a different code set)

IHE UK has also suggested using SNOMED (See Annex B at http://www.ihe-uk.org/MetaDataProposal - Note I’ve gone with the SNOMED codes for document types Annex A)
Does anyone have any thoughts on this? We can map the codes but it would be 80-90% of systems I come across would need to map [It’s probably ideal to have a direct link or use UK specialty codes for reporting, which could be a big reason for using UK codes]
