Gastrointestinal endoscopy
About 45340: Flexible sigmoidoscopy with balloon dilation
Reports flexible sigmoidoscopy in which an endoscopist passes and inflates a balloon through the scope to widen a rectal or sigmoid stricture.
During flexible sigmoidoscopy, the endoscopist guides a dilation balloon through the scope to a narrowed area in the rectum or sigmoid colon, then inflates it under endoscopic visualization to enlarge the passage. Gastroenterologists and colorectal surgeons commonly perform this treatment for a stricture that limits passage through the distal bowel, including a narrowing at a surgical anastomosis. The procedure may take place in an endoscopy unit or hospital outpatient setting.
Report 45340 when the flexible sigmoidoscopy includes transendoscopic balloon dilation; diagnostic inspection alone is not the dilation service. The procedure note should identify the narrowed site and document balloon dilation. 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. Medicare does not pay an assistant at surgery for this code, and co-surgery and team surgery are not permitted.

For 45340 in Chico, the physician’s office rate is $549.67 and the facility-setting rate is $73.04: a difference of $476.63.

45340 billing questions
When should 45340 be chosen over 45330?
Use 45340 when a balloon is passed through the flexible sigmoidoscope and inflated to widen a stricture. Use 45330 for diagnostic flexible sigmoidoscopy without that therapeutic dilation.
Can the diagnostic sigmoidoscopy be reported separately?
Inspection of the bowel as part of the dilation procedure is integral to reporting 45340. Do not separately report a diagnostic examination for that same scope passage.
What documentation supports 45340?
Document the stricture's location and the transendoscopic balloon dilation performed. The record should make clear that dilation, rather than inspection alone, was carried out.
Should modifier 50 be appended for a stricture on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; report the sigmoidoscopy dilation without modifier 50.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 45340. Co-surgeons and team surgery are not permitted for this code.
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.
