CPT® Code 32400

The procedure described by CPT® Code 32400 refers to a percutaneous needle biopsy of the pleura, which is the thin membrane that covers the lungs and lines the chest cavity. This procedure is performed to collect a tissue sample from the pleura for diagnostic purposes. The process begins with the selection of an appropriate access site on the patient's body, typically on the chest, where the pleura can be accessed safely. Prior to the insertion of the biopsy needle, the skin at the access site is thoroughly cleansed to minimize the risk of infection. A local anesthetic is then administered to numb the area, ensuring that the patient experiences minimal discomfort during the procedure. Following the administration of the anesthetic, a small incision is made to facilitate the insertion of the biopsy needle. The needle is carefully inserted into the pleural space, and its cutting edge is positioned against the pleura to obtain a tissue sample. It is important to note that multiple passes with the needle may be necessary to secure an adequate sample for analysis. This procedure is crucial for diagnosing various conditions affecting the pleura, including infections, tumors, and other pathological processes. The percutaneous approach allows for a minimally invasive method to obtain necessary tissue for further examination, aiding in the accurate diagnosis and management of pleural diseases.
