Operation Definition
Completely closing an orifice or the lumen of a tubular body part
Procedure Overview
Occlusion procedures close off a urinary structure completely, most often a ureter, so that urine or another substance can no longer pass through it. This is done when a ureter must be sealed off because of an unrepairable fistula, a nonfunctioning kidney left in place, or a urinary diversion in which the natural path from kidney to bladder is intentionally interrupted. The occlusion can be achieved surgically by ligating or clipping the ureter, or by placing material inside the vessel to block flow.
Patients who undergo this procedure often have advanced disease affecting kidney function or urinary drainage, such as a kidney destroyed by long-standing obstruction, and the goal is to prevent urine leakage or infection rather than to restore normal function.
Anatomy & Axis Detail
Urethra
The urethra transports urine from the bladder to the exterior and, in males, also carries semen, making its patency essential to normal voiding. Occlusion of the urethra is a deliberate procedure to close the lumen, typically performed in cases of severe incontinence unresponsive to other treatments, following extensive reconstruction where a diversion is planned instead, or in select gender-affirming or trauma contexts, using suture ligation, an occlusive device, or surgical closure of the lumen. Because blocking the urethra removes the body's normal route for urine egress, it is almost invariably accompanied by creation of an alternative drainage pathway such as a suprapubic tube or continent stoma, and careful documentation distinguishes true occlusion from procedures like dilation or restriction that narrow but do not fully close the channel.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Device: Intraluminal Device
Intraluminal Device denotes a single device, such as a stent or occlusion device, positioned within the lumen of a tubular body part like a vessel, duct, or airway to maintain patency or occlude flow. It carries no drug coating or radioactivity, distinguishing it from the drug-eluting, radioactive, and bioactive intraluminal device values, and from Extraluminal Device, which sits outside rather than inside the lumen.
Coding & Documentation
Coders should confirm from the operative note that the intent was complete closure of the lumen, not narrowing or repair, since Occlusion requires that no material can pass through afterward. Documentation should specify the exact segment of ureter closed and the method used, whether suture ligation, clipping, or an endoluminal occluding device, because the approach value depends on how access was gained.
A common mistake is confusing occlusion with Restriction, which only partially narrows a lumen rather than closing it entirely; if any flow is still possible, Restriction is the correct root operation instead. Another frequent error is coding an occlusion performed as part of a larger diversion or nephrectomy procedure as a separate line item when it was an integral step of that more comprehensive procedure and should not be coded independently.
Commonly Confused With
This family is most often confused with Restriction, since both narrow a tubular structure, and with an incidental ligation performed as a step of another procedure. The key distinction from Restriction is whether the lumen is completely closed versus only partially narrowed. The distinction from an incidental ligation is whether closing the ureter was the primary objective of the procedure or merely a technical step within a more extensive operation such as a nephroureterectomy, in which case it is not coded separately.
