What 45309 covers

A clinician uses a rigid proctosigmoidoscope to examine the rectum and distal sigmoid and remove a tumor, polyp, or other lesion with a snare. Gastroenterologists and colorectal or general surgeons may perform the procedure in an endoscopy unit, hospital, or office setting. The snare technique distinguishes this service from lesion removal by hot biopsy forceps or bipolar cautery and from flexible sigmoidoscopy.

Select the code when the procedure documentation supports rigid scope use and snare removal; record the lesion site, findings, and technique. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, Medicare endoscopy-family pricing applies. Modifier 50 is inappropriate for this anatomy. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery reporting 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.

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.
