In simple words: This code describes a lung surgery where the doctor takes a small sample of lung tissue for testing and then removes a larger part of the lung, all during one operation. The small sample helps the doctor decide how much lung to remove.

This CPT code, 32668, represents a thoracoscopic (VATS) diagnostic wedge resection of the lung, performed in conjunction with a more extensive anatomical lung resection (such as lobectomy, segmentectomy, etc.) within the same anatomical location during the same operative session.The diagnostic wedge resection is performed to obtain a tissue sample for intraoperative pathology consultation, informing the extent of the subsequent, more extensive resection. This code is reported in addition to the code for the more extensive procedure.

Example 1: A patient presents with a suspicious lung nodule detected on CT scan.A VATS is performed, and a diagnostic wedge resection (32668) is done followed by a lobectomy (32480) after intraoperative pathology confirms malignancy., A patient with a history of lung cancer undergoes a follow-up VATS. A diagnostic wedge resection (32668) is performed on a new nodule, revealing metastatic disease.A segmentectomy (32482) is then carried out., During a VATS for suspected lung cancer, a diagnostic wedge resection (32668) is taken.Intraoperative pathology shows benign disease; therefore, no further resection is performed.Only code 32668 is reported.

Operative report detailing the procedure, including the size and location of the wedge resection and the larger resection, intraoperative pathology results confirming the necessity of the more extensive resection, and imaging studies showing the lesion(s).
