What 44379 covers
An endoscopist advances an enteroscope beyond the second portion of the duodenum to examine the small intestine and place an endoscopic stent. The service may be performed by a gastroenterologist or another appropriately trained endoscopist in a hospital or ambulatory endoscopy setting to open a narrowed segment or relieve an obstruction. Predilation performed to facilitate stent placement is included in the service.
Choose this code when the documented intervention is endoscopic stent placement, rather than diagnostic examination or tissue sampling alone. The procedure report should support the extent of enteroscopy, the treated site and reason for stenting, and placement of the stent. This minor procedure has 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 not appropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

44379 billing questions
When should this code be selected instead of a small-bowel biopsy code?
Use this code when the endoscopic service includes stent placement. A biopsy code such as 44361 describes a different intervention and does not substitute for documented stenting.
Is predilation separately reported with the stent placement?
Predilation to facilitate placement is included in this service.
What documentation supports reporting this code?
The procedure report should identify the enteroscope's extent, the small-bowel site and clinical reason for treatment, and the endoscopic stent placement.
How are related endoscopies handled when performed during the same session?
CMS endoscopy family pricing applies when related endoscopies are performed together. Same-day preoperative and postoperative care is included in the 0-day global period.
Can modifier 50 be used, or can co-surgeons be reported?
Modifier 50 is not appropriate for this service. Co-surgeons are not permitted; assistant-at-surgery payment requires documentation of medical necessity.
