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

Procedure Overview

This family describes procedures that completely close off part of the airway, most often to stop air or secretions from passing through a specific bronchus or to control a leak. A common application is placing an endobronchial valve to block airflow into a diseased or overinflated portion of the lung, a technique used in lung volume reduction for severe emphysema or to seal a persistent air leak after surgery or trauma. Occlusion may also be used to manage a bronchopleural fistula by blocking the affected airway segment, giving the surrounding lung tissue a chance to heal.

Anatomy & Axis Detail

Lingula Bronchus

The lingula bronchus supplies the tongue-shaped projection of the left upper lobe that functionally mirrors the right middle lobe, arising as a discrete branch off the upper lobe bronchus rather than as its own lobar airway. Occlusion of this small segment is used when bleeding, infection, or air leak is isolated to the lingula and the operator wants to spare the remainder of the upper lobe from intervention. Its narrow caliber and variable branching pattern make selective cannulation more demanding than for a true lobar bronchus, and correct identification during bronchoscopy is essential to avoid inadvertently occluding adjacent upper lobe segments instead.

Approach: Via Natural or Artificial Opening Endoscopic

Via Natural or Artificial Opening Endoscopic describes instrumentation introduced through a natural orifice or a surgically created opening while using an endoscope for visualization, as in a routine colonoscopy performed through the anus. It differs from the plain Via Natural or Artificial Opening value by the added scope, and from Percutaneous Endoscopic by using an existing passage rather than a new skin puncture.

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 select this family when the documentation describes a deliberate, complete blockage of an airway lumen, whether achieved with an implanted valve, coil, or other blocking material, or by suturing or clipping a bronchus shut. The device value and specific bronchial or tracheal body part must match the operative note precisely, since occlusion is frequently performed at a segmental or subsegmental level. A common error is coding a therapeutic valve placement as Insertion alone without recognizing that the intent to block airflow makes Occlusion the more accurate root operation, or missing that occlusion of a bronchus during lobectomy for stump closure is typically integral to the resection and not coded separately.

Commonly Confused With

RestrictionOcclusion is often confused with Restriction, which narrows rather than completely closes a lumen; a partially constricting band would be Restriction, while a valve or ligature that stops all airflow is Occlusion.
ExcisionIt also differs from Excision, since occlusion leaves the airway segment in place but nonfunctional rather than removing tissue.
