ECMO/ECLS surgery

About 33985: Open removal of central ECMO cannulae

Reports open removal of central cannulae after ECMO or ECLS support, when the patient is ready to be decannulated from central access.

This service covers open removal of central cannulae used for extracorporeal membrane oxygenation or extracorporeal life support. It is typically performed by a cardiac or cardiothoracic surgeon when support ends and the central cannulae, such as those placed in the heart or great vessels, can be removed. Central access is distinct from peripheral access, such as cannulation through a femoral vessel.

Select the code based on central cannula removal by the open approach, not the original cannulation site alone. The operative report should identify the cannulae removed, their central location, the open approach, and the decannulation performed. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeon and team-surgery payment require supporting documentation.

How does 33986 differ?
