CPT® Code 33915

The procedure described by CPT® Code 33915 refers to a pulmonary artery embolectomy performed without the use of cardiopulmonary bypass. This surgical intervention is aimed at removing an embolus, which is a blockage in the pulmonary arteries that can impede blood flow to the lungs. The procedure typically involves accessing the pulmonary arteries through a median sternotomy or thoracotomy, which are surgical approaches that allow the surgeon to reach the heart and lungs. During the operation, the main pulmonary artery and its branches are carefully dissected to free them from surrounding tissues, ensuring that the area is adequately exposed for the removal of the embolus. It is important to note that if cardiopulmonary bypass were to be utilized, a different code (CPT® Code 33910) would be applicable. The distinction between these two codes is crucial for accurate medical coding and billing, as it reflects the complexity and the specific techniques employed during the procedure.
