Gastrointestinal endoscopy
About 44394: Stomal colonoscopy with snare removal
Report this service when a colonoscope is passed through a stoma and a colonic lesion is removed using a snare during the examination.
A gastroenterologist or colorectal surgeon advances a colonoscope through a colonic stoma to examine the colon and remove a tumor, polyp, or other lesion with a snare. This may occur during an outpatient endoscopy or a hospital-based procedure for a patient with a colostomy. The approach through the stoma and the snare removal distinguish this service from routine inspection, forceps removal, and colonoscopy performed through the anus.
Select the code from the access route and documented removal technique; the report should identify the stoma approach and the lesion treatment performed. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy family pricing applies. Modifier 50 is inappropriate because the descriptor and anatomy do not support bilateral adjustment. CMS does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

44394 billing questions
How does this differ from 44392?
Both describe lesion removal during colonoscopy through a stoma. Use 44394 for snare removal; 44392 is for removal by hot biopsy forceps or bipolar cautery.
When is 44389 more appropriate?
Use 44389 when tissue is sampled by biopsy during colonoscopy through a stoma rather than removed by snare.
Can the diagnostic examination be billed separately?
The code describes snare removal during the examination, not a separate diagnostic-only procedure. When related endoscopies are performed together, CMS endoscopy family pricing applies.
Should modifier 50 be reported?
No. The descriptor and anatomy make bilateral adjustment and modifier 50 inappropriate.
Can an assistant or co-surgeon be paid?
CMS does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
