"TECHNIQUE: Using sterile technique and ultrasound guidance to access the vessel, patency was shown, and after anesthetizing the skin with lidocaine, the right common femoral artery was punctured successfully. A permanent image was created and stored. Using sterile technique and local anesthetic, a 6 French sheath was placed in the right common femoral vein via modified Seldinger technique. A 5 French long vertebral catheter was placed in the superior vena cava through a 6 French Benchmark catheter. We then advanced the catheter into the right vertebral vein. A venogram was performed. We then advanced a Headway Duo microcatheter over a Synchro Softip microguidewire to the C5-C6 radicular vein. A venogram was performed. The vein was then embolized using Onyx 34. A final x-ray and XperCT were performed." 

Can you please help with the coding? I came up with 76937, 36012 x 2, 76496 x 2, 61624, 75894, and 76377. This was done on an independent workstation under direct supervision and interpretation. If the spinal venograms were diagnostic, would they be reported with unlisted code 76496?
