What 33954 covers

This service covers percutaneous placement of peripheral cannulae to establish extracorporeal membrane oxygenation or extracorporeal life support in patients age six and older. A cardiothoracic or vascular surgeon, or another physician qualified to perform the access, places cannulae through peripheral vessels; femoral vessels are common access sites. The service is performed in settings such as an operating room or intensive care unit when urgent circulatory or respiratory support is needed.

Select this code for percutaneous peripheral cannulation in the specified age group; use the applicable sibling code when the age group or insertion approach differs. Document the patient’s age, peripheral access site, percutaneous technique, and cannula placement. The 0-day global period includes same-day preoperative and postoperative care. 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% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

33954 billing questions

How does 33954 differ from 33951?

33954 is for percutaneous peripheral cannula insertion in a patient age six or older. Choose 33951 when the insertion approach and the patient’s age match that code’s criteria instead.

When should a central cannula insertion code be used instead?

Use the central cannula insertion family when cannulae are placed centrally rather than through peripheral vessels. Code 33954 describes percutaneous peripheral access.

Can this be reported with an ECMO/ECLS initiation code?

Peripheral cannula placement may be reported with the applicable initiation service when both services are performed and documented. Select the initiation code for the veno-venous or veno-arterial circuit.

Can modifier 50 be appended for cannulation on both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

What documentation supports 33954?

Record the patient’s age, the peripheral vessel access site, the percutaneous approach, and the cannula placement performed for ECMO/ECLS.

May an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
