Procedure Overview
Occlusion procedures on the upper arteries close off the lumen of a vessel completely, cutting off blood flow through that specific segment. Surgeons and interventional specialists use this approach to stop bleeding, seal off an aneurysm, or block blood supply to a tumor or an abnormal tangle of vessels before it can cause harm. The upper arteries covered here include branches such as the innominate, subclavian, axillary, brachial, and the vessels supplying the head, neck, and upper limb.
A common reason for occluding one of these arteries is to treat an aneurysm that cannot be safely repaired by reinforcing its wall. Instead, the vessel feeding it is sealed so pressure inside the bulge drops and the risk of rupture falls. Occlusion is also used to control hemorrhage after trauma, to manage arteriovenous malformations, or to reduce blood flow to a vascular tumor before it is surgically removed, making the operation less bloody.
The closure itself may be achieved with a clip, a ligature, coils delivered through a catheter, or an injected embolic agent, and it can be done through an open incision or a minimally invasive endovascular route.
Anatomy & Axis Detail
Radial Artery, Right
The right radial artery runs along the lateral forearm from the brachial artery to the wrist, where it is a common site for arterial catheter access and blood gas sampling, and it contributes to the deep palmar arch supplying the hand. Occlusion of this artery is frequently a recognized complication following its use for cardiac catheterization or arterial line placement, but it is also performed deliberately to treat a pseudoaneurysm, an arteriovenous fistula, or as part of managing a radial artery harvested for other purposes. Before intentional occlusion, an assessment of ulnar artery collateral flow through the palmar arches, such as an Allen's test, is standard to confirm the hand will remain adequately perfused. The procedure can be done through a small incision at the wrist or forearm, or endovascularly, and the operative note should specify the exact segment involved.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
A coder selects an Occlusion code when the documentation shows the vessel's lumen is being shut down entirely, not narrowed or reinforced. The operative note needs to state which specific upper artery branch was targeted, the method used to achieve closure (clip, coil, plug, embolic material, or suture ligation), and whether the approach was open, percutaneous, or percutaneous endoscopic, since that determines the approach character of the code.
The most frequent assignment error is confusing Occlusion with Restriction, which only narrows the lumen rather than closing it off completely; the physician's language about "partial" versus "complete" closure is the deciding factor and should be confirmed rather than assumed. Another common mistake is missing that embolization procedures, though performed under interventional radiology, still map to Occlusion when the intent is total vessel closure, and coders sometimes miscode the device value when a liquid embolic agent is used instead of an intraluminal device.
