What 49450 covers

This service covers percutaneous replacement of an existing gastrostomy or cecostomy tube, with fluoroscopic guidance and contrast assessment to confirm tube position and function. It is commonly performed by an interventional radiologist in an imaging suite when a tube is dislodged, malfunctioning, or due for exchange. It is a replacement through an established tract, not creation of a new gastrostomy or cecostomy tract.

Report the code when documentation supports replacement of the existing tube and the imaging work associated with the exchange. The 0-day global includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this service. 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.

49450 billing questions

How does this differ from 49451 or 49452?

49450 is for replacing a gastrostomy or cecostomy tube. Use 49451 for a duodenostomy or jejunostomy tube and 49452 for a gastrojejunostomy tube.

Can the fluoroscopic tube check be reported separately?

Fluoroscopic guidance, contrast assessment, and related image documentation for the replacement are included in 49450. Do not separately report a tube check for that same work.

When is 49450 preferable to 43762?

49450 describes replacement with fluoroscopic guidance. 43762 is for percutaneous gastrostomy tube replacement without imaging or endoscopic guidance.

Does 49450 have a global period?

It has a 0-day global period, so same-day preoperative and postoperative care is included.

Can modifier 50 be used for two tubes?

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.
