About 44401: Colonoscopy through stoma with ablation
Reports endoscopic ablation of a colonic lesion during colonoscopy performed through a stoma, when tissue is treated rather than resected.
A gastroenterologist or colorectal surgeon uses a colonoscope passed through a colostomy or other stoma to ablate a tumor, polyp, or other lesion in the colon. Ablation destroys the targeted tissue in place rather than removing it as a specimen; it may be selected when the lesion is not treated by a removal technique. The procedure is typically performed in a hospital outpatient or ambulatory endoscopy setting.
Report this code when the stoma is the route of access and ablation is the principal lesion treatment. The operative note should identify the stoma route, lesion location and treatment performed, and distinguish ablation from resection or injection. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed in the same session, endoscopy family pricing applies. Modifier 50 is inappropriate; assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.

44401 billing questions
How does this differ from 45388?
This code is for colonoscopy performed through a stoma. Code 45388 describes colonoscopic ablation through the standard route rather than through a stoma.
When should 44403 be selected instead?
Use 44403 when the lesion is treated by endoscopic resection through the stoma. Use 44401 when the documented treatment is ablation rather than removal.
Can ablation and another endoscopic service be reported together?
Related endoscopies performed in the same session are subject to CMS endoscopy family pricing. Document each service actually performed; the family-pricing rule affects payment.
Should modifier 50 be appended for multiple lesions?
No. CMS identifies bilateral adjustment as inappropriate for this code. The descriptor concerns colonoscopy through a stoma, not a bilateral procedure.
What documentation supports reporting 44401?
Document the stoma route, the lesion's location, and that the lesion was ablated. The note should make clear that treatment was ablation rather than resection or injection.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
