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
Main Bronchus, Left
The left main bronchus is longer than its right counterpart and takes a shallower, more horizontal course beneath the aortic arch before splitting into upper and lower lobe branches. Occlusion of this airway isolates the entire left lung and is used for uncontrolled left-sided hemoptysis, a bronchopleural fistula following left pneumonectomy or lobectomy, or to achieve single-lung isolation when double-lumen intubation is not feasible. Its close relationship to the aorta, esophagus, and left pulmonary artery means the procedure is documented with attention to the proximal-to-distal extent of occlusion, since sealing too far proximally risks compromising airflow that should remain patent to unaffected segments.
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.
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.
