Gastrointestinal endoscopy
About 44366: Small-bowel enteroscopy with hemostasis
Reports extended small-bowel endoscopy used to stop bleeding beyond the second portion of the duodenum when the examined segment does not include the ileum.
A gastroenterologist advances an enteroscope beyond the second portion of the duodenum to identify and treat a bleeding source in the small bowel, without examining the ileum. This service is used when bleeding is seen during enteroscopy, such as from a small-bowel vascular lesion or ulcer. Hemostasis may involve an endoscopic technique such as injection, thermal treatment, or mechanical clipping.
Report this code when the endoscopy includes active treatment to control bleeding, rather than diagnostic inspection alone, biopsy alone, or removal of a lesion as the primary service. The procedure note should support the extent examined, the bleeding site, and the hemostasis method. 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. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

44366 billing questions
When should 44366 be reported instead of a diagnostic enteroscopy?
Use 44366 when the enteroscopy includes endoscopic treatment to control bleeding. Diagnostic inspection without hemostasis is represented by 44360 when the examined segment does not include the ileum.
How does 44366 differ from 44365?
44366 is for controlling bleeding. 44365 describes removal of a lesion using hot biopsy forceps or bipolar cautery, rather than hemostasis as the reported service.
Can a separate diagnostic enteroscopy be billed with 44366?
When related endoscopies are performed together, CMS endoscopy-family pricing applies. The documentation should show the services performed and the distinct clinical work supporting any additional reported endoscopy.
Can modifier 50 or an assistant-at-surgery claim be used?
No. CMS identifies bilateral adjustment as inappropriate for this code and does not pay an assistant at surgery for it.
What documentation supports reporting 44366?
Document the small-bowel segment reached, the bleeding source or site, and the endoscopic method used to control bleeding. The documented extent should not include the ileum for this code.
What is the global period for 44366?
It has a 0-day global period. Same-day preoperative and postoperative care is included.
