CPT® Code 50688

The procedure described by CPT® Code 50688 involves the change of a ureterostomy tube or an externally accessible ureteral stent through a previously established ileal conduit. An ileal conduit is a surgical procedure that creates a passage for urine to exit the body when the bladder is not functioning properly. In this context, the physician performs the procedure by first utilizing radiographic guidance, which involves imaging techniques to visualize the internal structures during the procedure. A guidewire and sheath are introduced through the ileal conduit, allowing for the safe removal of the existing ureterostomy tube or stent. Once the old tube or stent is removed, a new one is prepared and advanced over the guidewire into the ureter, ensuring that it is correctly positioned. The use of radiographic verification is crucial in this procedure to confirm the proper placement of the new device before the guidewire is removed, ensuring the effectiveness and safety of the intervention.
