Dear Andreas
We have received mappings of VNRs and NCSP codes, and we have also mapped some ourselves. In addition we have mapped TNM codes and non-surgical procedure codes (from the SKS system). I can suggest you to take part in the Danish OHDSI node, where we plan to share and review each others mappings. Denmark . These mappings also include NPU codes from the LAB registry and more.
What type of codes do you intend to map?
