ECMO procedures
About 33963: Peripheral ECMO cannula repositioning
Report this procedure when a physician repositions an existing peripheral ECMO or ECLS cannula to address a documented positioning problem.
This procedure addresses the position of a peripheral cannula already in use for extracorporeal membrane oxygenation (ECMO) or extracorporeal life support (ECLS). A physician adjusts an arterial or venous cannula, such as one placed through femoral or jugular vessels, when its position interferes with support or creates another documented concern. The work may occur in an intensive care unit or operating room and is distinct from placing a new cannula or removing one at the end of support.
Report 33963 for the documented peripheral cannula repositioning procedure, not for routine monitoring or circuit management alone. The procedure note should identify the cannula and access site, the reason for adjustment, and the repositioning performed. CMS assigns a 0-day global period, so routine preoperative and postoperative care on the procedure date is included. When multiple procedures occur in one session, CMS pays the highest-valued procedure in full and other procedures at 50%. Modifier 50 is inappropriate. Payment for an assistant at surgery, co-surgeons, or a surgical team requires supporting documentation.

33963 billing questions
When is 33963 reported instead of a peripheral cannula insertion code?
Use 33963 for repositioning an existing peripheral ECMO or ECLS cannula. Codes such as 33951 describe insertion rather than adjustment of a cannula already in place.
Does routine ECMO management support reporting 33963?
No. The record must describe a procedure that repositions the peripheral cannula; monitoring circuit performance alone does not establish that work.
Is same-day care separately included with 33963?
CMS assigns a 0-day global period, which includes routine preoperative and postoperative care on the procedure date.
Should modifier 50 be used if more than one peripheral cannula is adjusted?
No. CMS does not apply a bilateral adjustment to 33963, and modifier 50 is inappropriate.
What supports payment for additional surgeons on 33963?
An assistant at surgery requires documentation of medical necessity. Co-surgeons and team surgery also require supporting documentation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
