What 49452 covers

An interventional radiologist or other physician with image-guided access expertise replaces an existing gastrojejunostomy tube through its established percutaneous tract. The service is used when the tube is displaced, obstructed, damaged, or requires exchange while maintaining gastric access and jejunal feeding access. Fluoroscopy may guide the exchange and verify tube position; it is included when performed. This is a replacement service, not initial creation of a gastrostomy or jejunostomy tract.

Report 49452 for percutaneous exchange of a G-J tube, rather than a G-tube or a duodenal or jejunal tube alone. The record should identify the existing tube, reason for replacement, access used, device placed, and any imaging confirmation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment requires medical-necessity documentation, and co-surgeon and team-surgery reporting 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.

49452 billing questions

How is 49452 different from replacing a G-tube or a jejunal tube?

Use 49452 when the existing tube is a gastrojejunostomy tube. Code 49450 addresses a gastrostomy or cecostomy tube, while 49451 addresses a duodenostomy or jejunostomy tube.

Can fluoroscopy be reported separately with 49452?

Fluoroscopy used to guide or verify the replacement is included when performed. Do not separately report it as a distinct imaging service for that same exchange.

What documentation supports reporting 49452?

Document the existing G-J tube, why it needed replacement, the percutaneous access used, the tube placed, and imaging or position confirmation when performed.

Does modifier 50 apply, and when can an assistant be paid?

Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeon and team-surgery reporting 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. If other procedures are performed in the same session, CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full and others at 50%.

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.
