Hallo, I’m pretty new to OMOP and I’m having difficulties mapping non-standard codes to standard codes. I got it right on some vocabularies, but not on ICD10. Hope someone can point me in the right direction.
Example is ICD10 code ‘D12.6’. Which I can find perfectly fine online in Athena. It gives me a concept_id of ‘45576377’. It also says that it has a Non-standard to Standard map (OMOP) to concept_id ‘77234’ from the SNOMED vocabulary. This is exactly what I need. A mapping tot a standard SNOMED term that I can use in loading data into OMOP.
However, I’m unably to find this mapping relation anywhere in the vocabularies I downloaded. I downloaded the ICD10 vocabulary and expected to find a line where concept_id_1 = ‘45576377’, relationship_id = ‘Maps to’ and concept_id_2 = ‘77234’ in the CONCEPT_RELATIONSHIP.csv. Unfortunately it’s not there.
What am I missing?
