Ask Dr. Z

Are codes 93451, 37211-50, and 36014-50 correct for the following procedure? (Patient had diagnostic CT priot to this procedure.)

"A balloon-tipped Swan-Ganz catheter was advanced serially through the right heart chambers (pressures were measured) and was then advanced up into the right main pulmonary artery into the wedge position where pulmonary wedge pressure was measured. Another wire was advanced through the catheter lumen and advanced into the mid lobe of the right pulmonary artery. Another wire was able to be selectively directed into the left main pulmonary artery and the left mid branch. It was used to perform selective angiogram of the main pulmonary artery. This catheter was removed. The 12 cm long EKOS catheters were then advanced along each of the two V-18 wires and positioned carefully with their proximal infusion edge being above the level of the pulmonic valve. Following positioning, the V-18 wires were removed and replaced with the inner core wires of the EKOS catheters to provide ultrasonic drug delivery. The catheters were then sutured in place and connected appropriately to the infusion devices. Thrombolytic infusion was initiated per protocol."
