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
Carina
The carina is the cartilaginous ridge marking the bifurcation of the trachea into the right and left main bronchi, and occluding it means sealing this junctional point, most often to control a bronchopleural fistula, massive air leak, or hemorrhage originating near the bifurcation when more distal or proximal occlusion would not adequately isolate the problem. Because the carina sits deep in the mediastinum adjacent to major vascular structures and both mainstem bronchi, occlusion here is technically demanding and is generally reserved for situations where isolating a single bronchus is insufficient. The procedure is typically performed bronchoscopically using an occlusive device or sealant delivered under direct visualization at the bifurcation.
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
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.
