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.

45309 billing questions

How does this differ from code 45308?

This code identifies snare removal during rigid proctosigmoidoscopy. Code 45308 is for lesion removal using hot biopsy forceps or bipolar cautery.

Can this code describe flexible sigmoidoscopy with snare removal?

No. This code is for rigid proctosigmoidoscopy; flexible sigmoidoscopy with snare removal is reported with code 45338.

What documentation supports the code?

Document that a rigid proctosigmoidoscope was used and that a lesion was removed with a snare. Include the lesion location and procedural findings.

Can modifier 50 be used?

No. Modifier 50 is inappropriate for this rectal and distal sigmoid service.

How are related endoscopies priced when performed together?

Medicare endoscopy-family pricing applies when related endoscopies are performed together. The payment calculation follows that family pricing rather than treating each as an unrelated procedure.

Is an assistant or co-surgeon payable for this procedure?

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

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.
