What 44373 covers

The endoscopist advances a small-bowel scope beyond the second portion of the duodenum and guides a feeding tube through the upper gastrointestinal tract into the jejunum. This service is generally performed by a gastroenterologist or surgeon in an endoscopy or hospital setting when enteral nutrition needs to be delivered beyond the stomach. The tube placement is the distinguishing therapeutic service; a diagnostic examination alone does not support this code.

Report the service when the procedure record supports both the enteroscopy and endoscopic tube placement, including the tube’s destination. When related endoscopies are performed together, CMS endoscopy-family pricing applies. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate because bilateral adjustment does not apply. Medicare does not pay an assistant at surgery for this code; 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.

44373 billing questions

How does this differ from diagnostic enteroscopy?

This code is for enteroscopy with endoscopic placement of a nasojejunal feeding tube. A diagnostic enteroscopy without that placement is represented by a different code.

What documentation supports reporting it?

Document the enteroscopic approach, the endoscopic guidance, and the feeding tube’s jejunal destination. The record should establish that tube placement was performed, not merely planned.

Can the diagnostic enteroscopy be billed separately during the same procedure?

The endoscopic examination used to place the tube is part of this service. When related endoscopies are performed together, CMS endoscopy-family pricing applies.

Should modifier 50 be appended?

No. CMS identifies bilateral adjustment as inapplicable for this code, making modifier 50 inappropriate.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this service, and 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.
