"Right and left common femoral veins were cannulated antegrade fashion. 11 French sheaths were placed. 5 French multipurpose catheter and 0.35 wire were used and placed through IVC into the right atrium. Intracardiac echo catheter was placed through the left side. We went through into the right atrium and interrogated this. We identified the septum. A specific defect or tunnel was not initially visualized with color flow. We did not see a jet. Attempt was then made with multiple wires and a multipurpose catheter. We placed this up against the septum. At one point, the catheter did go out into the pulmonary artery. However, despite multiple attempts and actually placing the catheter directly on the septum, no defect could be identified. Contrast bubble study was then performed. Again, this was done directly with contrast injection into the SVC and right atrium. There were no crossing bubbles across. At this point, we were confident that there was no septal defect identified." Should we report codes 36013 and 93662-26 or codes 93580-52 and 93662-26? And why?
