What 45398 covers
A gastroenterologist, colorectal surgeon, or other qualified endoscopist performs a colonoscopy and places bands endoscopically to treat hemorrhoidal tissue, commonly internal hemorrhoids. The colonoscope is used to reach and treat the target during the same procedure; this is distinct from band ligation performed through a sigmoidoscope, which examines a shorter portion of the bowel.
Report this code when the colonoscopy includes hemorrhoid band ligation, and document the examination, hemorrhoid treatment, and procedure performed. A diagnostic inspection during the same session is part of the therapeutic colonoscopy rather than a separate diagnostic colonoscopy claim. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy family pricing applies. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

45398 billing questions
When should 45398 be selected instead of 45350?
Use 45398 when the band ligation is performed during colonoscopy. Use 45350 when the procedure is performed with a sigmoidoscope rather than a colonoscope.
Can the diagnostic colonoscopy be reported separately?
Do not separately report a diagnostic colonoscopy for the inspection that is part of the same therapeutic colonoscopy with band ligation.
How are related endoscopies handled in the same session?
CMS endoscopy family pricing applies when related endoscopies are performed together. Document the procedures performed during the session.
Should modifier 50 be appended for multiple hemorrhoids?
No. CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
Can an assistant, co-surgeon, or surgical team be billed?
CMS does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
What does the 0-day global period include?
Same-day preoperative and postoperative care is included in the procedure.
