12.02.2019 General Guideline 37: Measures That Use Medication Lists General Guideline 37 states that if an organization uses both pharmacy data (NDC codes) and clinical data (RxNorm codes) for reporting, to avoid double counting, deduplicate and count an NDC code and an RxNorm code for the same drug on the same date of service as only one dispensing event. If a measure specification says, “if multiple prescriptions for the same medication are dispensed on the same day, sum the days supply,” should the days supply from the pharmacy data event and the clinical data event be summed?

The intent of GG 37 is to prevent double-counting when an organization uses both pharmacy data (NDC codes) and clinical data (RxNorm codes) for reporting, because the same dispensing event can have both an NDC code in the pharmacy data and an RxNorm code in the clinical data. Because the two codes identify the same dispensing event (not two dispensing events), count an NDC code and an RxNorm code on the same date of service as one dispensing event and do not sum the days supply.
