About 44405: Colonoscopy with balloon dilation
Reports colonoscopy during which a narrowed colonic segment is therapeutically dilated, typically with a balloon passed through the endoscope.
A flexible colonoscope is advanced to a narrowed area of the colon, and a dilation device is used through the scope to widen the stenosis. Gastroenterologists and colorectal surgeons commonly perform this treatment for symptomatic narrowing, including a stricture at a surgical anastomosis, in a hospital outpatient department or ambulatory surgery center. The service is therapeutic rather than a routine colonoscopy alone.
Select this code when dilation is performed during the colonoscopy. Document the indication, stricture location and findings, dilation method, and procedural result. 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 governs payment rather than independent pricing for each procedure. An assistant at surgery is not paid under the statutory restriction; co-surgeons and team surgery are not permitted.

44405 billing questions
When should this code be chosen instead of a colonoscopy with stent placement?
Use this code when the colonoscopic treatment is dilation of a narrowing. A procedure that places a stent is represented by the stent-placement service instead.
What documentation supports reporting dilation?
Record the reason for treatment, the narrowed segment and its findings, the dilation technique, and the result. The record should show that dilation was actually performed.
How are related endoscopies priced when performed together?
CMS applies endoscopy-family pricing to related endoscopies performed together, rather than treating each as independently priced.
Is same-day postoperative care included?
Yes. This code has a 0-day global period, which includes same-day preoperative and postoperative care.
Can an assistant, co-surgeon, or surgical team be billed?
An assistant at surgery is not paid under the statutory restriction. Co-surgeons and team surgery are not permitted for this service.
