I’m doing a code mapping from ATC to RxNorm and RxNorm Extension based on the mapping from Athena. I found some of the ATC concepts map to multiple RxNorm concepts. Here is an example:
21600006 sodium monofluorophosphate; oral
In this case, should I create two drug_exposure records for one source record? I think it’s ok for the “Condition” domain according to the previous post ICD10CM to SNOMED. But not sure if the same applies to “Drug” domain as well.
Thank you very much and please let me know if I get this wrong.
