Ask Dr. Z

The patient came for possible creation of AV graft. No prior mapping was done prior to arrival in OR. A venogram was performed via direct puncture. Venogram showed several areas of stenosis within the cephalic vein; however, decision was made to proceed with PTA of cephalic vein prior to creation of brachiocephalic fistula. Dissection was carried down to the cephalic vein and vessel exposed. A Fogarty balloon catheter was used to dilate the vein. Following successul angioplasty, the fistula creation was completed. Would it be appropriate to code the open PTA (35460) and the venogram (36005/75820) separately or are these considered part of the AV creation? Thanks in advance for your assistance.
