I’m currently working on a large set of national EHR data and trying to map them to OMOP CDM. All the diagnoses are given as ICD-10 codes, but approx 5% of them do not have a corresponding mapping to standard concepts. So, I’ve prepared a custom mapping for them, but I can’t see a reason why they shouldn’t be part of the standard mapping. For instance:
45606791 ICD-code “Epistaxis” has currently no mapping, but should have a relationship to 4096682 Standard concept “Bleeding from nose, epistaxis”
However, it has been unclear to me to where to submit or git commit such mappings or what is the relevant “board” to review these mappings…?
