See email from Children’s Colorado. What source is used for the OMOP RxNorm codes and how often is that source updated from the NLM RxNorm master terminology?

Subject: RxNorm updates to omop concept table
Do you know how often the rxnorm codes get updated in the concept table?
Out of the distinct 38k rxnorm codes in the clarity rxnorm_codes table, 2k of them don’t have a corresponding rxnorm code in the concept table.
I’ve taken handful of the rxnorm codes that don’t match to the omop concept table and verified them against RXNav and they are truly RXnorm codes.
