What 43251 covers
A gastroenterologist or other qualified endoscopist uses a flexible upper endoscope and a snare to remove a polyp or other lesion from the esophagus, stomach, or duodenum. The service is commonly performed in a hospital outpatient department or an ambulatory endoscopy center, with the removed tissue typically sent for pathology. The defining feature is removal by snare, rather than sampling alone or removal by a different method.
Report the service for the snare removal performed during the EGD, not once for each lesion removed in the same session. The procedure report should identify the lesion site and describe its removal technique and the findings. CMS 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. The assistant-at-surgery statutory restriction means Medicare does not pay an assistant for this procedure; co-surgeons and team surgery are not permitted.

43251 billing questions
When should this code be used instead of 43239?
Use this code when a snare is used to remove the lesion. Code 43239 describes biopsy sampling rather than snare removal.
Is the code reported once for each polyp?
No. Report the snare-removal service once for the EGD session, even when more than one lesion is removed by snare.
How does this differ from 43250?
This code describes snare removal. Code 43250 is used when a lesion is removed with hot biopsy forceps or bipolar cautery.
Can a separate biopsy code be reported during the same EGD?
A biopsy code describes sampling, while this code describes snare removal. Document each service and lesion clearly; do not assume both are separately reportable for the same lesion.
Can modifier 50 be used for lesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; the anatomy or descriptor does not support modifier 50.
Does Medicare pay an assistant or co-surgeon for this procedure?
The assistant-at-surgery statutory restriction prevents Medicare payment for an assistant. Co-surgeons and team surgery are not permitted.
