Ask Dr. Z

Would I report 36901 and 36907 or 36902? "The right arm was prepped using ChloraPrep. Under ultrasound guidance, the right brachial basilic vein transposition fistula was accessed in antegrade fashion near the arterial anastomosis. A fistulogram was performed in stations to the chest. This demonstrated a recurrent, severe approximately 75% stenosis of the right brachiocephalic vein. Given the excellent palpable thrill of the fistula, assessment of the arterial anastomosis was deferred. Subsequently, the stenosis was angioplastied to 16 mm using a 16 mm x 4 cm Atlas Gold angioplasty balloon. Repeat fistulogram was performed. This demonstrated improvement in the brachiocephalic vein stenosis but with persistent moderate stenosis remaining. The stenosis was again angioplastied to 16 mm using the Atlas Gold balloon with prolonged angioplasty balloon inflation time utilized. Repeat fistulogram was performed, demonstrating mild less than 30% residual narrowing of the brachiocephalic vein."
