What 44366 covers
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.
