CPT® Code 33050

The procedure described by CPT® Code 33050 involves the surgical resection of a pericardial cyst or tumor through an open approach. The pericardium, which is the fibrous membrane encasing the heart, can develop cysts or tumors that may require surgical intervention. During this procedure, the surgeon typically employs a median sternotomy or an anterolateral thoracotomy to gain access to the thoracic cavity and the heart. Once the thoracic cavity is opened, the surgeon inspects the area to locate the cyst or tumor. It is crucial to identify and protect the right and left phrenic nerves during the operation to prevent any complications. If the lesion is identified as a cyst, the surgeon may open it to evacuate any fluid and debris contained within. The next step involves carefully dissecting the cyst, tumor, or mass from the surrounding tissues and removing it along with a margin of healthy pericardium to ensure complete excision. After the resection, the defect in the pericardium may be addressed by either covering it with a synthetic patch or leaving it open to allow for drainage. In cases where the defect is left open, a chest tube is inserted into the defect, and an additional chest tube is placed in the pleural space to facilitate proper drainage and recovery.
