Ask Dr. Z

I know I will be using unlisted code 37799 for the AV fistula creation, but what embolization code if any would I code? Or should that be part of the unlisted code? Also do I bill separate for the catheter placements for the fistula creation or should that be part of the unlisted code? "A 5 French catheter was then introduced through the venous sheath and into the brachial vein. Transcatheter embolization of the brachial vein was performed with a single 8 mm coil in order to encourage fistula flow through the perforator vein and into the superficial access sites. Post embolization angiogram demonstrates successful embolization with diminished flow through the brachial vein."
