What 44361 covers
A gastroenterologist or other qualified endoscopist advances an enteroscope beyond the second portion of the duodenum to examine the small bowel and obtain tissue samples. The examined segment may include the jejunum, but this code excludes examination of the ileum. Biopsies may be taken from abnormal-appearing mucosa or to investigate suspected small-bowel disease, such as a cause of malabsorption or unexplained anemia. These procedures are commonly performed in a hospital outpatient department or ambulatory endoscopy center.
Report 44361 when the endoscopist obtains one or more tissue biopsies during the qualifying examination; the number of samples does not create separate procedure units. The report should support the route and extent of the examination, the biopsy sites, and the reason for sampling. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted. Bilateral adjustment does not apply, and modifier 50 is inappropriate.

44361 billing questions
When should 44361 be reported instead of 44360?
Use 44361 when tissue biopsy is obtained during the qualifying small-bowel examination. Use 44360 for the diagnostic examination when no tissue biopsy is performed.
Does the code include multiple biopsy samples?
Yes. One or multiple biopsies during the examination are included in the procedure service; do not report a separate unit for each sample.
Can 44361 be used when the endoscopist examines the ileum?
No. This code describes examination beyond the second portion of the duodenum without including the ileum. For an examination that includes the ileum with biopsy, compare 44377.
How is 44361 handled when another related endoscopy is performed in the same session?
CMS endoscopy-family pricing applies when related endoscopies are performed together. The record should identify each examination and any distinct intervention or biopsy performed.
Is modifier 50 appropriate, and can an assistant or co-surgeon be paid?
No. Bilateral adjustment does not apply, and modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
What documentation supports reporting 44361?
Document the endoscopic route and extent, the small-bowel segment examined, the biopsy site or sites, and the clinical reason for obtaining tissue.
