Ask Dr. Z

Sx background: Patient had mediatinoscopy with bx done and three days after developed bleeding from mediatinoscopy done three days before. The MD placed the patient on cardiopulmonary bypass through the left femoral artery and vein as well as venous catheter in the right atrium, median sternotomy, and mediastinal exploration. All of these were done to control of bleeding. On the same sx session he did 33025. Is 32110 the correct code for the control of bleeding? The provider is choosing the add-on code 33369 (no TAVR was done). The provider wants to bill the cardiopulmonary bypass as well with the control of bleeding. I can't find any code close to what he did (coronary bypass to control the bleeding).
