"LT brachiocephalic vein catheterization and venography via RT CFV access. Next, the LUE fistula was cannulated and a catheter was then advanced to the left axillary vein and venography performed from LUE access. Venograms demonstrated total occlusion of the left subclavian vein with large and tortuous draining collateral vein. A catheter and hydrophilic wire were then used thru the RT groin sheath in an attempt to negotiate thru the occluded left subclavian vein. A gooseneck snare was advanced thru the LUE catheter in attemtp to capture the wire from above, however this was unsuccessful despite multiple attempts. It was decided to perform radiofrequency wire recanalization. Appropriate grounding pads were placed on the patient's thighs and the radiofrequency wire was advanced thru a catheter from below and recanalization performed in the subclavian/axillary vein junction. The wire was snared with a gooseneck and removed thru the LUE. Balloon catheter was used to perform venoplasty of LT subclavian vein." Are codes 35476, 36147, 36012, 75820, and 75978 correct? Are there additional codes for radiofrequency wire recanalization?
