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

What 33955 covers

This service covers placement of central cannulae for extracorporeal membrane oxygenation or extracorporeal life support through a sternotomy or thoracotomy in a patient from birth through age five. A cardiothoracic or cardiac surgeon typically performs it in an operating room, including when central access is established during or after cardiac surgery. Central cannulation places access directly in the chest rather than through peripheral vessels.

Select this code based on the patient’s age and the central surgical access documented in the operative report; peripheral cannulation is coded separately. The record should support the need for ECMO/ECLS, the chest approach, and cannula placement. Same-day preoperative and postoperative care is included in the 0-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeon and team-surgery claims require supporting documentation.
