One of our QRDA files submitted for CY2021 has an outcome from CMS as Numerator_met. However, the patient had a principal procedure with ICD10PCS code 0SPD0JZ which is in the "Knee Replacement Surgery" value set.  The procedure was done during the inpatient encounter. I am trying to understand why the case was not a denominator exclusion based on the principal procedure.  I have attached a file with screen shots of the encounter performed and the procedure performed portions of the QRDA file that was submitted.
