Cardiothoracic surgery
About 33951: Peripheral ECMO Cannula Insertion, Percutaneous
Reports percutaneous placement of peripheral ECMO/ECLS cannulae for patients age five or older, such as femoral vascular access for extracorporeal support.
This service covers percutaneous placement of cannulae in peripheral vessels to establish extracorporeal membrane oxygenation or extracorporeal life support. It is used when a patient needs temporary circulatory or respiratory support, including situations requiring peripheral access such as femoral cannulation. Cardiothoracic and other surgeons who perform ECMO access procedures commonly provide the service in a hospital setting. The age threshold for this code is five years or older.
Select this code when the cannulae are placed percutaneously in peripheral vessels; use a different code when the patient is younger or the access is open or central. The operative record should identify the access approach, peripheral site, cannula placement, and patient age. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures occur 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 documented medical necessity; co-surgeons and team surgery are not permitted.

33951 billing questions
How does 33951 differ from 33952?
Both describe percutaneous peripheral ECMO/ECLS cannula insertion. Use 33951 for patients age five or older and 33952 for patients younger than five.
When should 33953 be considered instead?
33953 describes open peripheral cannula insertion for patients age five or older. The access technique, rather than the peripheral site alone, distinguishes it from 33951.
Is modifier 50 appropriate for cannulation on both sides?
No. The CMS bilateral adjustment does not apply to 33951, and modifier 50 is inappropriate.
What documentation supports reporting 33951?
Document the patient's age, the peripheral access site, the percutaneous approach, and placement of the cannulae for ECMO/ECLS.
Can an assistant-at-surgery be reported?
Assistant-at-surgery payment is limited to cases with documented medical necessity. Co-surgeons and team surgery are not permitted.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
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.
