Gastrointestinal endoscopy
About 45349: Flexible sigmoidoscopy with endoscopic mucosal resection
Reports endoscopic mucosal resection of a lesion reached by flexible sigmoidoscopy, typically when a colorectal lesion is lifted and removed endoscopically.
A gastroenterologist or colorectal surgeon uses a flexible sigmoidoscope to reach a lesion in the rectum or sigmoid colon and perform endoscopic mucosal resection (EMR). The technique commonly involves lifting the lesion from the underlying wall, often with a submucosal injection, then removing the targeted mucosa with an endoscopic resection instrument. It is performed in an endoscopy setting for lesions selected for endoscopic rather than surgical removal.
Report this code when the documented therapeutic service is EMR during flexible sigmoidoscopy, not merely inspection, biopsy, or routine snare removal. The report should identify the lesion’s location and describe the EMR technique and resection performed. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate; CMS also does not pay an assistant at surgery, and does not permit co-surgeons or team surgery for this service.

45349 billing questions
How does this differ from 45333?
Use 45349 for EMR performed through flexible sigmoidoscopy. Code 45333 describes a different lesion-removal technique, snare removal, rather than EMR.
Can diagnostic sigmoidoscopy be reported separately with the EMR?
The inspection that leads to EMR is part of the therapeutic endoscopy. When related endoscopies are performed together, Medicare applies endoscopy family pricing.
What documentation supports reporting 45349?
Document the lesion’s location and the EMR technique and resection performed. The record should distinguish EMR from biopsy, diagnostic examination, or another removal method.
Should modifier 50 be appended for lesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant surgeon or co-surgeon be billed?
CMS does not pay an assistant at surgery for this service and does not permit co-surgeons or team surgery.
