Ask Dr. Z

We have been trying to decide how to appropriately bill for a stress echo when there are different supervising and interpreting physicians. They are from the same practice/specialty, but I am not finding anything definitive on how to bill. When Cardiologist A is supervising (overseeing both the stressing and echocardiogram) and Cardiologist B is interpreting, do we bill the following: Under Cardio A: 93351-TC, 93320-TC, and 93325-TC. Under Cardio B: 93351-26, 93320-26, and 93325-26. Or: Under Cardio A: 93351-TC, 93320-TC, and 93325-TC. Under Cardio B: 93350-26, 93320-26, and 93325-26? We are having conflicting views in our office as to how to bill and are wanting to verify the correct way.
