Internalization of stent via ileal conduit

Date: Dec 13, 2018

Question:

Patient with an ileal conduit with current nephrostomy tube comes in for internalization to a double-J ureteral stent. Nephrostomy is removed and replaced with the stent coiled within the ileal conduit. Would you consider this 53899 for initial stent placement via ileal conduit, 50693 for stent via pre-existing nephrostomy tract, or 50688 for replacement even though the tubes were two different types?
