What 37616 covers
This service involves surgically exposing and tying off a major arterial trunk within the chest. It is typically performed by a vascular, cardiothoracic, or trauma surgeon in an operating room when permanent interruption is needed, commonly to control operative or traumatic hemorrhage. The documented vessel must be a major artery in the chest; the incision or route of access alone does not determine the code.
Select this code by the artery’s location and the work performed, rather than by the underlying diagnosis alone. The operative report should identify the vessel, its thoracic location, the reason for ligation, and the procedure performed. This major operation has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.
Can an assistant or co-surgeon be reported?

What postoperative care is included?
