Ask Dr. Z

Would the ECMO portion be coded as 33946? "Using real-time US guidance, a 21 gauge micropuncture needle was first used to enter the right internal jugular vein. A 5 French sheath was placed. A second access higher up on the right internal jugular vein was placed with US guidance. Additionally two more access points were placed into the left internal jugular vein. One access point was used for a triple-lumen central line and handed off to anesthesia. Additional access was also gained with US guidance of the left common femoral vein. The right IJ access point was upsized to a 26 French Gore dry seal sheath. A flush catheter was then advanced through the sheath into the lower IVC. Next the left IJ access was upsized to a 17 French ECMO cannula. In conjunction with the perfusionist team and the manufacture representative, the patient was placed on venovenous bypass. After the conclusion of the RLE mechanical thrombectomy procedure, the patient was taken off the venovenous bypass, and all sheaths were removed and hemostasis achieved with pursestring sutures."
