Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33880 covers

A vascular or cardiothoracic surgeon uses catheter-based delivery to place an endograft in the descending thoracic aorta, excluding disease such as an aneurysm, dissection, pseudoaneurysm, penetrating ulcer, or traumatic disruption. This code distinguishes a repair that covers the left subclavian artery origin from one that leaves that origin uncovered. These procedures are typically performed in a hospital operating room or hybrid suite.

Select the code based on the operative anatomy and the repair performed: documentation should identify the aortic disease and show that the initial endoprosthesis covers the left subclavian origin. Extensions placed as part of the initial repair are included in the procedure; delayed extension placement is represented by separate codes. The CMS global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery and co-surgeon payment are permitted; team surgery is not permitted.
