What 45307 covers

A clinician advances a rigid proctosigmoidoscope through the anus to locate and retrieve a foreign object in the rectum or distal sigmoid. A gastroenterologist, colorectal surgeon, or other qualified physician may perform the procedure in an office, endoscopy suite, or operating room, depending on the object and clinical circumstances. Retrieval instruments may be passed through the scope. This code describes foreign-body extraction, not removal of a polyp or other lesion.

Report 45307 when the documented procedure uses a rigid proctosigmoidoscope to remove the object. The record should identify the object and its location, the scope used, the retrieval performed, and relevant findings. 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. Assistant-at-surgery payment requires documentation of 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.

45307 billing questions

When should 45307 be chosen instead of 45332?

Use 45307 when the foreign body is removed with a rigid proctosigmoidoscope. Code 45332 describes foreign-body removal during flexible sigmoidoscopy.

Is 45307 appropriate for removing a polyp?

No. This code is for retrieval of a foreign object. Choose the code that describes the documented lesion-removal method when a polyp or other lesion is removed.

What should the procedure note support?

Document the foreign object, its location, use of a rigid proctosigmoidoscope, and the retrieval performed. Include relevant findings from the examination.

How are related endoscopies priced when performed together?

CMS endoscopy family pricing applies when related endoscopies are performed together.

Does the 0-day global include same-day care?

Yes. Same-day preoperative and postoperative care is included in the 0-day global period.

When can an assistant-at-surgery be paid?

Assistant-at-surgery payment is available only when the documentation supports medical necessity.

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.
