Thoracoscopy, surgical; with diagnostic wedge resection followed by anatomic lung resection (List separately in addition to code for primary procedure)

Thoracoscopy, surgical, with diagnostic wedge resection is a minimally invasive procedure aimed at evaluating diseased or damaged lung tissue. This technique is particularly useful in determining the extent of lung resection required during a subsequent anatomic lung resection, which is a more extensive surgical intervention that may be performed in the same surgical session. The procedure typically involves the use of a thoracoscope, a specialized instrument that allows the surgeon to visualize the thoracic cavity and the lung structures without the need for large incisions. The wedge resection is performed through a single portal incision, and the specific location of the incision and the thoracoscope's placement is determined by the location of the lung lesion being assessed. During the procedure, the surgeon identifies the lesion and utilizes an endograsper to grasp and suspend it for further evaluation. An endostapler is then employed to excise a wedge of lung tissue containing the lesion, ensuring that the tissue is carefully removed while minimizing damage to surrounding healthy lung parenchyma. The resected tissue is subsequently placed in an endobag for removal, and a chest tube may be inserted to facilitate drainage. This procedure is critical for obtaining tissue samples for pathology examination, which will inform the decision regarding any necessary definitive lung procedures that may follow.
