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.

33985 billing questions
How do I distinguish this from 33984?
Code 33985 is for open removal of central ECMO/ECLS cannulae. Code 33984 is for removal of peripheral cannulae.
How does 33986 differ?
33986 describes central cannula removal by a percutaneous approach. Use 33985 for open removal.
Can modifier 50 be used when more than one cannula is removed?
No. Modifier 50 is inappropriate for this service; removal of multiple cannulae does not make it a bilateral procedure.
What documentation supports reporting 33985?
Document that the cannulae were used for ECMO/ECLS, their central location, and that they were removed through an open approach. The operative note should describe the decannulation performed.
How are other procedures in the same session handled?
The highest-valued procedure is paid in full, and other procedures in the session are subject to the standard multiple-procedure reduction. Same-day preoperative and postoperative care is included in this code's 0-day global period.
What documentation is needed for assistant or team payment?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon and team-surgery payment require supporting documentation.
