I’m trying to map my medication dataset to OMOP drug_concept table as per V6 specifications. When I read through the drug_concept_id field, it has a link of accepted concepts which filters out all the vocabs that are not standard. So, NDC which seems to be non standard filters out as well… about 8.5% of my dataset is NDC type.
What are the repercussions of loading a non-standard concept_id into drug_concept_id field ?
OR do I just input drug_concept_id = 0 for NDC rows since only standard values are accepted and then may be set drug_source_concept_id = 45018605 for example for dicyclomine ?
