What 44370 covers

A gastroenterologist or other qualified endoscopist uses an endoscope to reach the small bowel and place a stent within its lumen. A typical clinical purpose is to maintain passage through a narrowed or obstructed segment. The service is generally performed in a facility setting; CMS recorded facility services for this code in 2024 and no office services.

Report the code when the documented endoscopic service includes small-bowel stent placement, rather than diagnostic inspection alone, biopsy, or another therapeutic maneuver. The report should identify the treated small-bowel segment, the indication, and the stent placement. 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, endoscopy family pricing applies. Modifier 50 is inappropriate for this anatomy and descriptor. 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.

44370 billing questions

When should this code be selected instead of a diagnostic small-bowel endoscopy code?

Use this code when the endoscopist places an intraluminal stent during the small-bowel endoscopy. Diagnostic inspection without stent placement is represented by a different service.

What documentation supports reporting the stent service?

Document the small-bowel segment treated, the reason for stenting, and that the stent was placed endoscopically. The report should distinguish placement from diagnostic inspection or biopsy alone.

Can modifier 50 be reported for bilateral stent placement?

No. CMS identifies bilateral adjustment as inappropriate for this code because the descriptor or anatomy does not support modifier 50.

How are related endoscopies paid when performed together?

Endoscopy family pricing applies when related endoscopies are performed together. Same-day preoperative and postoperative care is included in this code's 0-day global period.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
