CPT® Code 32484

A lung segmentectomy, as defined by CPT® Code 32484, is a surgical procedure that involves the removal of a specific segment of the lung rather than the entire lung or lobe. This procedure is typically indicated for patients diagnosed with early-stage lung cancer that is localized to a small area of the lung, allowing for targeted treatment while preserving as much healthy lung tissue as possible. The surgical approach begins with an incision made at the level of the affected lung segment, which is located on the front of the chest and extends around to the back, reaching a point beneath the shoulder blade. This incision provides access to the chest cavity, which may require the surgeon to maneuver around the ribs, and in some cases, a rib may be removed to enhance visibility and access to the lung segment. Once the chest cavity is opened, the surgeon identifies the diseased or damaged lung tissue and excises it. To facilitate recovery and prevent complications, a temporary drainage tube may be placed in the pleural space to help remove any air, fluid, or blood that accumulates at the surgical site. Finally, the chest incision is carefully closed to promote healing.
