Ask Dr. Z

Can you tell me if this would be considered an open procedure and if you would only report code 36832? "DuraPrep and sterile draping of the left upper extremity in the routine manner. Using the SonoSite, the location of the collateral vein arising from the left brachiocephalic arteriovenous was identified. An axial incision was made over the fistula at this location. Sharp dissection down to the fistula and the collateral vein, which was controlled by circumferential dissection and secured with 0 silk ties. Access through this large collateral vein with a micropuncture kit into the left upper arm brachiocephalic arteriovenous fistula. Insertion of a 6 French sheath.
