What 44394 covers

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.

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.

44394 billing questions

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.

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.
