What 49451 covers

Code 49451 describes exchanging a duodenostomy or jejunostomy tube through an established percutaneous tract. Fluoroscopy and contrast injections are used to guide the exchange and check tube position; radiological supervision and interpretation are part of the service. Interventional radiologists commonly perform the procedure in hospital or outpatient imaging settings when a tube is malfunctioning, displaced, or due for exchange. This is for an existing access tract, not creation of a new one.

Report the code when the documentation identifies the tube and tract exchanged and supports image-guided replacement. The fluoroscopy, contrast injections, and their interpretation are included in the code. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. If multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this tube exchange. An assistant is payable only when medical necessity is documented; 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.

49451 billing questions

How is 49451 different from 49441?

49451 is for exchanging an existing duodenostomy or jejunostomy tube through its established tract. 49441 describes percutaneous placement of a duodenal or jejunal tube, rather than replacement.

Can fluoroscopy or contrast be billed separately?

No. Fluoroscopic guidance, contrast injections, and radiological supervision and interpretation are included in 49451 for the tube exchange.

When is modifier 50 appropriate?

Modifier 50 is inappropriate for 49451; the service concerns an individual tube and is not a bilateral procedure.

What documentation supports reporting 49451?

Document the existing duodenostomy or jejunostomy access, the exchange performed, and the image-guided confirmation of the replacement tube's position.

How does the multiple-procedure reduction affect this code?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% reduction.

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.
