The left anterior chest wall was prepped and draped. Both venous and arterial ports of the catheter were de-heparinized with a 5cc syringe. Venous and arterial ports were aspirated, and small amounts of clots extracted from the catheter lumen. A central venogram view was performed identifying good flow into the right atrium. No clots or abnormalities noted. F/U completion venography noted widely patent central venous system with catheter tip position near the Cavo atrial junction. Excellent aspiration from the arterial port and venous port was noted. Both ports were flushed with normal saline. Findings: Preliminary scout film of the chest demonstrates an indwelling tunneled right IJ hemodialysis catheter with the tip positioned in the right atrium.

I am not sure how-to code for the clot aspiration along with the central venogram.
