Operation Definition

Completely closing an orifice or the lumen of a tubular body part

Procedure Overview

Occlusion procedures on the lower arteries deliberately seal off a vessel's opening or lumen so blood can no longer pass through it. This is done using techniques like embolization coils, particles, or glue delivered through a catheter, or by surgically tying off the artery, and it serves purposes ranging from stopping dangerous bleeding to cutting blood supply to a tumor or an abnormal vascular connection. Unlike most procedures aimed at restoring flow, this family intentionally blocks it.

Common reasons for occlusion include controlling a bleeding vessel after trauma or during surgery, shrinking uterine fibroids by blocking their blood supply, treating an aneurysm by closing off the feeding artery, or managing internal bleeding from the gastrointestinal or pelvic arteries. The approach can be catheter-based and minimally invasive or performed as part of an open surgical procedure.

Anatomy & Axis Detail

Peroneal Artery, Left

The left peroneal artery lies deep in the posterior compartment of the calf between the tibia and fibula and functions largely as a collateral and muscular supply vessel, with communicating branches linking it to the anterior and posterior tibial circulations, so it is relatively better tolerated to occlude than vessels directly feeding the foot. Indications for occlusion center on trauma, pseudoaneurysm formation, or an arteriovenous malformation localized to this artery, typically addressed with coil or particle embolization delivered under fluoroscopic guidance. Because this vessel does not independently supply the plantar or dorsal foot, procedural notes should confirm the patency of the anterior and posterior tibial arteries to establish that adequate collateral perfusion to the foot is preserved after the occlusion.

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 look for clear language that the artery was closed off entirely - terms like embolization, coiling, ligation, or clipping - and confirm from the note that the intent and result was complete closure rather than partial narrowing. The specific artery occluded needs to match the correct body part value, which for pelvic and reproductive procedures like uterine fibroid embolization can involve multiple small branches. A frequent mistake is confusing partial narrowing intended to reduce but not eliminate flow with true occlusion, or missing that embolization material used therapeutically differs from diagnostic catheter placement, which would not be separately coded.

Commonly Confused With

RestrictionRestriction is the procedure most easily confused with Occlusion, since both narrow a vessel, but Restriction only partially reduces the diameter or flow while Occlusion eliminates it completely - the operative note's description of the intended endpoint is the deciding factor.
DestructionDestruction is another neighboring concept when tissue rather than a vessel lumen is being eliminated, and coders should check whether the artery itself was closed versus abnormal tissue fed by it being obliterated.
