Gastrointestinal endoscopy
About 44390: Colonoscopy through stoma with foreign body removal
Reports colonoscopy performed through a stoma to retrieve a foreign object from the colon using an endoscopic instrument.
A gastroenterologist or colorectal surgeon uses a colonoscope passed through a colostomy stoma to locate and retrieve a foreign object in the colon. The service is typically performed in an endoscopy suite or hospital procedure setting when the object can be reached and removed endoscopically. The operative report should identify the route through the stoma, the foreign object, its location, and the retrieval performed.
Choose this code for endoscopic foreign-body removal through a stoma, rather than a diagnostic examination alone or treatment directed at a polyp, bleeding site, or tissue sample. 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 for this anatomy. Medicare does not pay for an assistant at surgery; co-surgeons and team surgery are not permitted.

44390 billing questions
How does this differ from code 45379?
Code 44390 describes foreign-body removal by colonoscopy through a stoma. Code 45379 is the corresponding foreign-body removal service through the usual anal route.
Can this code be used for a diagnostic examination through the stoma?
No. Use 44390 when the colonoscopy through the stoma includes endoscopic foreign-body removal. A diagnostic examination without that treatment is represented by a different code.
Is removal of a polyp or control of bleeding included?
This code is for foreign-body removal, not polypectomy or treatment of a bleeding site. Report the code matching the therapeutic service actually performed.
How should same-day related endoscopies be handled?
When related endoscopies are performed together, CMS endoscopy family pricing applies. The operative documentation should support each service and its distinct purpose.
Can modifier 50 or an assistant-at-surgery claim be reported?
Modifier 50 is inappropriate for this stoma-based service. Medicare does not pay an assistant at surgery for this code.
What documentation supports reporting 44390?
Document that the colonoscope entered through the stoma, the foreign object and its location, and the endoscopic retrieval performed.
