What 45315 covers

This procedure combines examination through a rigid proctosigmoidoscope with snare removal of a lesion in the rectum or distal sigmoid colon. A colorectal surgeon or gastroenterologist may perform it when a polyp can be reached through the rigid instrument. The procedure may take place in an office or outpatient facility, depending on the patient and setting.

Select this code from the operative note’s scope type, lesion location, and removal technique; a flexible sigmoidoscope or biopsy alone points to a different code. The diagnostic examination inherent in the removal is included. When related endoscopies are performed together, CMS applies endoscopy family pricing rather than simply adding their full payments. This is a 0-day global procedure, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this anatomy. CMS does not pay an assistant at surgery for this code and does not permit co-surgeons or team surgery.

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.

45315 billing questions

How is 45315 distinguished from flexible sigmoidoscopy with snare removal?

Use 45315 when the documented instrument is a rigid proctosigmoidoscope. Flexible sigmoidoscopy with snare removal is reported with 45338.

Is a diagnostic rigid proctosigmoidoscopy separately reported with 45315?

The examination performed as part of the snare removal is included. If another related endoscopy is separately reportable during the same session, CMS endoscopy family pricing applies.

What documentation supports 45315?

The procedure note should identify the rigid scope, the rectal or distal sigmoid lesion, and removal with a snare.

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.
