Operation Definition
Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part
Procedure Overview
This family involves putting in biological or synthetic material that physically takes over for a missing or damaged portion of the respiratory tract, most notably reconstruction of the trachea using graft material after a segment is removed for stenosis or tumor invasion. Unlike a lung transplant, which replaces the entire organ from a donor and is classified separately, these procedures typically address a segment of the airway wall.
Patients undergo these procedures when the trachea has been narrowed, weakened, or destroyed to the point that simple repair won't hold, often after prior injury from prolonged intubation, tumor removal, or a congenital defect. The graft, whether from the patient's own tissue, a donor, or a synthetic conduit, is meant to permanently stand in for the missing structure.
Anatomy & Axis Detail
Lingula Bronchus
The lingula bronchus supplies the lingula, the tongue-shaped projection of the left upper lobe that serves as the anatomic analog to the right middle lobe and shares its tendency toward recurrent infection and bronchiectasis from a relatively narrow airway. Replacement of this bronchus is rare and generally reserved for cases where tumor invasion or destructive fibrotic disease has eliminated a segment of the airway beyond simple repair, necessitating a graft to preserve aeration of the lingular segments rather than removing them outright. Its small caliber and proximity to the left upper lobe bronchus from which it typically arises make precise reconstruction technically demanding. Coders should look for explicit documentation that a substitute structure was placed into the airway, since more commonly this segment is treated by excision or repair rather than replacement.
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: Autologous Tissue Substitute
Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of manufactured material.
Coding & Documentation
Coding requires documentation confirming that material was placed to physically take the place of tissue that was removed or is absent, not merely reinforcing existing tissue. Operative notes should specify the graft or substitute material used and the segment of the airway or lung structure it replaces. A recurring error is confusing a patch graft over an existing airway wall, which is Supplement, with true segmental replacement following excision.
Commonly Confused With
The closest points of confusion are with Supplement, where original tissue remains and is only reinforced, and with Transplantation, reserved for whole-organ lung replacement from a donor. Checking whether the native structure was removed before the graft was placed, and whether the graft is a segment or an entire organ, resolves most of these distinctions.
