What 43241 covers

A gastroenterologist or other qualified endoscopist advances a flexible scope through the mouth to guide an intraluminal tube or catheter into the upper gastrointestinal tract. A common use is placing a nasoenteric feeding tube under direct visualization, including when blind advancement is unsuccessful or tube position needs endoscopic guidance. The procedure may be performed in a hospital or, less commonly, an office setting.

Choose this code when tube or catheter insertion is the therapeutic service, rather than simply inspecting the esophagus, stomach, and duodenum. The report should identify the indication, the tube or catheter placed, and the endoscopic guidance and placement performed. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

How to choose

43246PEG placement
Use 43241 for an intraluminal tube or catheter placed through the upper GI tract. Use 43246 when the endoscopist creates a gastrostomy and places a tube through the abdominal wall.
43248Esophageal dilation
43241 captures tube or catheter placement. 43248 is for guidewire-assisted esophageal dilation, not simply advancing a tube under endoscopic guidance.
43235Upper GI endoscopy
43235 describes diagnostic upper endoscopy without the tube-placement service. When the endoscopy guides tube insertion, report the therapeutic service rather than separately reporting the diagnostic examination.
43239EGD with biopsy
43239 is for mucosal biopsy during EGD. Use 43241 when the service performed is placement of an intraluminal tube or catheter; document any separately performed biopsy.

43241 billing questions

How is this different from gastrostomy tube placement?

This code covers endoscopic placement of an intraluminal tube or catheter through the upper gastrointestinal tract. Code 43246 describes endoscopic placement of a gastrostomy tube through the abdominal wall.

Can a diagnostic EGD also be reported?

The inspection performed as part of the tube-placement procedure is integral to that service. Do not separately report a diagnostic EGD code for the same examination.

What documentation supports reporting this code?

Document the clinical reason for placement, the type of tube or catheter, and how endoscopy was used to guide its placement. The record should distinguish tube placement from diagnostic examination alone.

Should modifier 50 be used for placement on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.

Can an assistant or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this service. Co-surgeon and team-surgery billing are not permitted.

What happens when another related endoscopy is performed in the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. Report the procedures supported by the operative note, with the applicable family pricing reflected in payment.

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.
