About 33966: Open peripheral ECMO cannula removal
Reports open surgical removal of peripheral ECMO or ECLS cannulae when extracorporeal support ends and the cannula is removed through an operative approach.
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.

33966 billing questions
How is this code distinguished from 33965?
This code is for open removal of peripheral ECMO/ECLS cannulae; 33965 is the percutaneous removal counterpart. Use the approach documented in the operative report.
Does this code include initial cannula placement or repositioning?
No. It represents cannula removal. Placement and repositioning are separate services with their own codes and documentation requirements.
What does the 0-day global period include?
Same-day preoperative and postoperative care is included. The global period does not extend beyond the day of the procedure.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted under the CMS rules for this code.
Can modifier 50 be used for bilateral removal?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this descriptor and anatomy.
