CPT® Code 32561

Instillation(s), via chest tube/catheter, agent for fibrinolysis (eg, fibrinolytic agent for break up of multiloculated effusion); initial day

The procedure described by CPT® Code 32561 involves the instillation of a fibrinolytic agent via a chest tube or catheter into the pleural space. This procedure is typically performed to address multiloculated effusions, which are collections of fluid in the pleural cavity that can become trapped due to the formation of fibrinous bands or loculations. The process begins with the cleansing of the skin and the administration of a local anesthetic to minimize discomfort. A small incision is made to facilitate the insertion of a chest tube or catheter into the pleural space. If fluid is present, it is drained to allow for better access and treatment. The fibrinolytic agent, which may include medications such as streptokinase or urokinase, is then instilled through the chest tube or catheter. These agents work by breaking down fibrin, thereby helping to dissolve the loculations and improve the drainage of any purulent material that may be present. After the instillation, the chest tube is temporarily closed to allow the fibrinolytic agent to disperse throughout the pleural space effectively. Once the agent has adequately spread, the chest tube is reopened, and both the fibrinolytic agent and any remaining purulent material are suctioned out. The chest tube may remain in place for several days to ensure continued drainage of fluid from the chest, facilitating recovery and preventing further complications. This code is specifically used for the initial day of the fibrinolytic agent instillation, while subsequent days are coded differently.
