Ask Dr. Z

An angled Glidewire was then passed through the short sheath to the level of the aortic arch and exchanged for a vertebral catheter, which was guided into the right subclavian artery, and the vertebral catheter was exchanged for a 6 French shuttle select sheath passed over a stiff Supracore wire. Innominate right subclavian and right common carotid angiography was performed and allowed us to localize the site of triple lumen catheter placement as the proximal to mid right subclavian artery. Using balloon occlusion using a 6 x 20 mm balloon, we had the anesthesia service remove the triple lumen catheter from the neck. We then elected to treat this by deploying a 6 x 16 mm iCAST covered stent because there was a fair amount of bleeding coming from the right neck, and angiography performed at this point revealed what appeared to be bleeding pseudoaneurysm. The balloon occlusion portion is stumping me. I don't think I should use code 35475.  Thoughts?
