CPT® Code 32402

Deleted

The procedure described by CPT® Code 32402 refers to an open biopsy of the pleura, which is the membrane lining the lungs and the chest wall. This procedure is performed to obtain a tissue sample from the pleura for diagnostic purposes. The process begins with the selection of an appropriate access site, followed by cleansing the skin to minimize the risk of infection. A local anesthetic is then administered to numb the area from the skin down to the pleural level, ensuring patient comfort during the procedure. A small incision is made to allow for the insertion of a biopsy needle into the pleural space. The needle, equipped with a cutting edge, is carefully positioned to penetrate the pleura, where a tissue sample is collected. It is important to note that multiple passes with the needle may be necessary to secure an adequate sample for analysis. In cases where an open technique is employed, an intercostal incision is made directly over the biopsy site, allowing for direct access to the pleura. After the tissue sample is obtained, a chest tube is typically placed to facilitate drainage, and the operative wound is subsequently closed around the chest tube to promote healing and prevent complications.
