About 45315: Rigid proctosigmoidoscopy with snare lesion removal
Report this service when a clinician uses a rigid proctosigmoidoscope to remove a rectal or distal sigmoid polyp or other lesion with a snare.
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.

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.
Does the 0-day global period include care on the procedure date?
Yes. Same-day preoperative and postoperative care for this minor procedure is included.
Can modifier 50 or surgical team billing be used for 45315?
