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

What 33966 covers

This service covers surgical removal of peripheral cannulae used for extracorporeal membrane oxygenation or extracorporeal life support. A surgeon, commonly a cardiothoracic or vascular surgeon, removes the cannula through an open approach, typically in a hospital operating room or intensive care setting when a patient is ready to come off extracorporeal support. The service concerns removal of the cannula, not its initial placement or repositioning.

Select this code when the documented removal uses an open approach and matches the code’s cannula and patient criteria; distinguish it from the percutaneous removal variant. The operative note should identify the peripheral cannula removed and describe the open removal. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
