About 35311: Brachiocephalic trunk endarterectomy
Open endarterectomy of the brachiocephalic trunk through a thoracic incision treats obstructive arterial disease, with patch closure included when performed.
This code represents open removal of obstructive plaque from the brachiocephalic trunk through a thoracic incision; patch closure, if performed, is part of the service. A vascular or cardiothoracic surgeon typically performs the operation in a hospital operating room for clinically significant trunk disease affecting blood flow to the head or right upper extremity. The operative report should identify the brachiocephalic trunk, the thoracic approach, and the endarterectomy performed.
Report the code for the specified vessel and approach, not for a neck-incision endarterectomy of the carotid, vertebral, or subclavian arteries. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For a bilateral service reported with modifier 50, payment is at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
