In this AV fistulogram the cathater moves to subclavian artery and subclavian vein what will be the cathater codes.(36145 access into graft if it moves to subclavian vein it becomes 36011 if it moves to subclavian artery it becomes 36120)

After administering local anesthesia to the overlying skin,
crossing 7-French vascular sheaths were placed into the graft.
Contrast injection with digital imaging of the graft and venous
outflow in the frontal projection was performed. A 4-French
Berenstein catheter was advanced through the upper sheath, guided
beyond the arterial anastomosis and further advanced centrally.
The catheter tip was positioned within the right subclavian
artery. A right upper extremity angiogram and frontal projection
was performed.

The intragraft stenoses were dilated using an 8 mm X 4 cm high
pressure angioplasty balloon. The subclavian vein stenosis was
dilated using a 14-mm by 4-cm Atlas angioplasty balloon. A post
angioplasty angiogram was performed demonstrating wide graft
patency. The subclavian vein is widely patent. An improved thrill
was palpated within the graft at this time. The sheaths were
removed and hemostasis was obtained with manual compression.
