What 44372 covers
This service involves advancing an endoscope beyond the second portion of the duodenum, without entering the ileum, and placing a tube or catheter through the endoscope. Gastroenterologists typically perform it in a hospital or ambulatory endoscopy setting when endoscopic guidance is needed to position the device in the small bowel. The report should establish the extent of examination and describe the placement performed; routine diagnostic inspection alone does not capture the tube-placement service.
Select this code when the documented intervention is tube or catheter insertion, rather than biopsy, stent placement, or dilation. Record the indication, endoscopic route and extent, device placed, and its final position. CMS assigns 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. Medicare does not pay an assistant at surgery, co-surgeons, or a team of surgeons for this service.

44372 billing questions
How is this different from diagnostic small-bowel enteroscopy?
This code is for enteroscopy beyond the second portion of the duodenum, excluding the ileum, with tube or catheter placement. Use the diagnostic code when the service is inspection without that placement.
Does tube placement support this code if the endoscopist also examines the bowel?
The defining intervention is endoscopic tube or catheter placement. Document the examination extent and device placement; inspection alone is not enough.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code’s anatomy and descriptor.
How are related endoscopies priced when performed together?
CMS applies endoscopy family pricing when related endoscopies are performed together. The applicable pricing reflects the family rule rather than treating every related endoscopy as an independent full service.
Can an assistant or another surgeon be billed for this procedure?
CMS does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.
What is included in the global period?
The code has a 0-day global period. Same-day preoperative and postoperative care is included.

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.
