Q: Would it be appropriate to report CPT ® code 75984 (change of percutaneous tube or drainage catheter with contrast monitoring [e.g., genitourinary system, abscess], radiological supervision and interpretation) for the following procedure: A small amount of contrast was injected through the indwelling nephrostomy drainage catheter. This demonstrated the catheter is well positioned within the renal collecting system. There is a small amount of thrombus attached to the tip of the pigtail catheter. The existing catheter was cut and a guidewire was advanced through the catheter into the renal collecting system. The existing catheter was removed over the wire and exchanged for a new 10 French nephrostomy tube. The catheter was secured to the skin with 2-O suture and covered with a sterile dressing.
