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.
