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

What 33947 covers

This service covers starting venoarterial extracorporeal membrane oxygenation or extracorporeal life support, which returns oxygenated blood to the arterial circulation while supporting cardiac and respiratory function. Cardiothoracic or vascular surgeons and other physicians involved in ECMO care may perform the initiation in an intensive care unit, operating room, or emergency setting. Typical circumstances include cardiogenic shock, cardiac arrest, or inability to separate from cardiopulmonary bypass when temporary extracorporeal support is needed.

Report 33947 for the initiation phase, not for ongoing daily management. The record should establish the clinical need for support, the venoarterial configuration, and the physician’s role in starting the circuit. Cannula insertion has its own codes when that work is performed and separately reportable; identify the cannula site and procedure in the documentation.
