Endoscopy

About 44389: Colonoscopy through stoma with biopsy

Reports examination of the colon through a stoma when the endoscopist takes one or more tissue samples during the procedure.

Code 44389 describes endoscopic examination of the colon through an existing stoma, with tissue sampling during the procedure. A gastroenterologist or colorectal surgeon may use it to evaluate abnormal mucosa, a suspected neoplasm, or another finding in a patient with a colostomy. The access route is the stoma; a colonoscopy performed through the anus belongs to a different code family.

Report the service when the procedure note documents access through the stoma, the examination performed, and the biopsy site or sites. The code includes the colonoscopy and biopsy, whether one or multiple samples are taken; do not count biopsy sites as separate units. If the endoscopist removes a lesion or treats bleeding, select the code describing that intervention. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. CMS endoscopy-family pricing applies when related endoscopies are performed together. Modifier 50 is inappropriate for this single examination. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

44389 billing questions

How does 44389 differ from 45380?

Code 44389 is for colonoscopy performed through a stoma. Code 45380 describes colonoscopy with biopsy through the usual anal route.

Do multiple biopsy sites create multiple units?

No. The code covers the examination with one or more biopsies; the number of sites or specimens does not create additional units.

Can the diagnostic stoma colonoscopy be billed separately?

The examination is included in 44389 when biopsy is performed during it. Do not separately report a diagnostic colonoscopy for that same examination.

Which code should be used if a lesion is removed?

Use the stoma-colonoscopy code that describes the removal technique, such as 44392 or 44394, rather than coding biopsy alone for the removal.

Can modifier 50 or an assistant-at-surgery claim be reported?

Modifier 50 is inappropriate for this single stoma examination. Medicare does not pay an assistant at surgery for 44389.

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.
