Gastrointestinal endoscopy

About 45389: Colonoscopy with colonic stent placement

Reports colonoscopic deployment of a stent across a colonic narrowing, commonly to relieve obstruction or maintain luminal patency.

A therapeutic endoscopist advances a colonoscope to a narrowed segment and deploys a stent through the instrument to maintain or restore passage through the colon. A common setting is an obstructing colorectal tumor, where stenting may relieve symptoms or serve as a bridge to planned surgery. Gastroenterologists and colorectal surgeons typically perform the service in a hospital or ambulatory surgery center, with imaging support when needed to guide placement.

Select this service when the colonoscopic procedure includes stent deployment, not for diagnostic inspection alone or balloon dilation without a stent. The report should identify the site and cause of the narrowing, the stent placed, and how deployment was completed. 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. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

45389 billing questions

When should 45389 be selected instead of 45347?

Is balloon dilation reported separately when a stent is placed?

45389 represents colonoscopic stent placement. Review the operative details and applicable coding edits before separately reporting another therapeutic endoscopy performed during the same session.

Can diagnostic colonoscopy be separately reported with 45389?

The inspection needed to reach and treat the narrowing is part of the therapeutic colonoscopy. When related endoscopies are performed together, CMS endoscopy family pricing applies.

What documentation supports 45389?

Document the location and cause of the narrowing, the reason for stenting, and the stent deployment details, including the device and final position.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the procedure's 0-day global period.

Can an assistant or co-surgeon be reported?

CMS does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
