What 45379 covers

A gastroenterologist or colorectal surgeon uses a colonoscope to locate and retrieve foreign material in the colon, often with an endoscopic retrieval device or forceps. The service may be performed in a hospital or ambulatory endoscopy setting when an object requires endoscopic removal. The record should identify the foreign material, its location, and the retrieval performed; routine inspection that does not include removal is not this service.

Select this code when the documented colonoscopy includes foreign-body retrieval, not when the procedure only evaluates the colon, takes a biopsy, or removes a lesion. The diagnostic examination is part of the therapeutic procedure. CMS assigns 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. Modifier 50 is inappropriate for this anatomy and service. Medicare does not pay an assistant at surgery for this service; 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.

45379 billing questions

How is this different from a diagnostic colonoscopy?

Use this code when the colonoscopy includes retrieval of a foreign object. A colonoscopy performed only to examine the colon, without foreign-body removal, is reported as a diagnostic colonoscopy.

Should a biopsy or lesion-removal code be used instead?

Use a biopsy or lesion-removal code when tissue is sampled or a lesion is removed, rather than a foreign object. The operative report should make clear what was retrieved or treated.

Can a diagnostic colonoscopy also be reported for the same procedure?

The inspection needed to locate and retrieve the foreign object is part of the therapeutic colonoscopy. CMS endoscopy family pricing applies when related endoscopies are performed together.

Does modifier 50 apply?

No. CMS identifies bilateral adjustment as inappropriate for this service and anatomy.

Can an assistant surgeon or co-surgeon be billed?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

What documentation supports reporting this code?

Document the foreign material, its location in the colon, and the endoscopic retrieval performed. The record should distinguish retrieval from biopsy, lesion removal, or inspection alone.

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.
