What 44377 covers
A gastroenterologist or other qualified endoscopist examines the small bowel beyond the second portion of the duodenum, including the ileum, and obtains one or more tissue samples through the endoscope. The service may help investigate suspected small-bowel inflammation, unexplained anemia, or an abnormality seen on imaging or prior testing. It is commonly performed in a hospital or ambulatory endoscopy setting.
Choose this code when the documented examination reaches the ileum and includes biopsy; the number of samples does not change the code. The report should support the extent of examination and tissue sampling. Medicare 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 code. 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.

44377 billing questions
How does this differ from 44361?
Use 44377 when the enteroscopy includes the ileum and biopsy. Code 44361 describes the related biopsy service when the examination does not include the ileum.
Does the number of biopsy samples change the code?
No. The code covers biopsy sampling whether the endoscopist obtains one sample or multiple samples.
Can a separate diagnostic enteroscopy code be reported for the same examination?
Do not report a second endoscopy code solely for the diagnostic examination that accompanies the biopsy. When related endoscopies are performed together, Medicare endoscopy family pricing applies.
Should modifier 50 be used for examination of both sides?
No. The anatomy and descriptor make bilateral adjustment inappropriate for this code.
What documentation supports reporting 44377?
Document that the enteroscope reached the ileum and that tissue was sampled. The note should distinguish this service from an examination that does not include the ileum.
When may an assistant be paid for this service?
Medicare assistant-at-surgery payment is available only when medical necessity is documented. 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.
