CPT® Code 39561

The procedure described by CPT® Code 39561 involves the resection of the diaphragm, which is a critical muscle that separates the thoracic cavity from the abdominal cavity and plays a vital role in respiration. This surgical intervention is typically indicated for patients with metastatic lesions that have spread from the lungs or other thoracic structures to the diaphragm. The resection is performed using a thoracic approach, which may include an anterolateral thoracotomy through an intercostal space, or alternatively, a median sternotomy, abdominal approach, or other surgical methods may be utilized depending on the specific clinical scenario. During the procedure, the surgeon excises the affected portion of the diaphragm along with a margin of healthy tissue to ensure complete removal of the pathological area. Following this extensive resection, the diaphragm is repaired using advanced techniques, which may involve the use of prosthetic material, such as a synthetic patch, or the development of a local muscle or fascial flap to facilitate closure. This complex repair is essential for restoring the integrity and function of the diaphragm post-resection.
