A patient with hydronephrosis underwent ureteral stent exchange. A cystoscope was inserted into the bladder. A wire was passed and the indwelling right ureteral stent was removed. A catheter was passed and retrograde pyelogram was then obtained. The ureteral stent was passed over a wire and the position of the stent was confirmed fluoroscopically and cystoscopically. What is the correct root operation for the exchange of the ureteral stents?
The objective of the stent placement is to continue to expand the ureter. “Dilation” is the appropriate root operation. Assign the following ICD-10-PCS code:
0TP98DZ Removal of intraluminal device from ureter, via natural or artificial opening endoscopic
0T767DZ Dilation of right ureter with intraluminal device, via natural or artificial opening“Change” is not the appropriate root operation, since the objective of the procedure is to dilate the ureter rather than exchange the device.
