CPT® Code 32557

The procedure described by CPT® Code 32557 involves the percutaneous drainage of the pleural space, specifically through the insertion of an indwelling catheter, which is guided by imaging techniques. This procedure is primarily performed to remove excess air or fluid that has accumulated in the pleural cavity, which can occur due to various medical conditions such as pleural effusion, pneumothorax, or infection. The process begins with the physician using an introducer needle to access the pleural cavity, followed by the insertion of an introducer wire. This wire serves as a guide for subsequent instruments. After the needle is removed, a dilator is placed over the wire to expand the puncture site, allowing for the insertion of a catheter. In some cases, a small incision may be made to facilitate access to the pleura. Once the catheter is in place, it is secured and connected to a suction unit, which may include a water seal chamber to prevent air from re-entering the pleural space. This procedure is critical for managing conditions that compromise respiratory function and requires careful imaging guidance to ensure accurate placement of the catheter.
