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

What 33949 covers

Code 33949 represents a physician’s daily management of venoarterial extracorporeal membrane oxygenation or extracorporeal life support. This support configuration returns oxygenated blood to the arterial circulation and may be used for severe cardiac or combined cardiopulmonary failure. Management typically occurs in an intensive care setting while the patient remains on support, with physician involvement from specialties such as critical care or cardiothoracic surgery.

Report the service for each date on which the physician provides the daily management, rather than for ECMO initiation or a cannula procedure. The record should support the physician’s assessment of the patient and circuit, management decisions, and any adjustments made to the support plan. Select this code for venoarterial support; the parallel daily-management code 33948 is for venovenous support.
