Gastrointestinal endoscopy
About 45333: Flexible sigmoidoscopy with hot-forceps lesion removal
Reports flexible sigmoidoscopy with removal of a colorectal lesion using hot biopsy forceps, such as treatment of a polyp found in the examined segment.
A flexible sigmoidoscope is advanced through the rectum to examine the lower colon. During the examination, the endoscopist uses hot biopsy forceps to grasp and remove a lesion, commonly a small polyp. Gastroenterologists and other physicians trained in gastrointestinal endoscopy perform this service in settings such as an endoscopy center or hospital outpatient department.
Select this code when the documented removal technique is hot biopsy forceps, rather than tissue sampling alone or removal by snare. The report should identify the examined segment, lesion, and removal method. When related endoscopies are performed in the same session, CMS applies endoscopy-family pricing rather than pricing each service independently. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment is barred, and co-surgeons and team surgery are not permitted.

45333 billing questions
When is this code appropriate instead of a biopsy code?
Use it when the lesion is removed with hot biopsy forceps. A procedure limited to taking tissue for examination is represented by the biopsy service.
How does this differ from snare removal?
This code identifies removal with hot biopsy forceps. Use the snare-removal code when the endoscopist removes the lesion using a snare.
How are related endoscopies in the same session paid?
CMS applies endoscopy-family pricing when related endoscopies are performed together, rather than pricing each as an independent endoscopy.
What documentation supports reporting this service?
Document the flexible sigmoidoscopy, the lesion and its location, and that hot biopsy forceps were used to remove it.
Can modifier 50 or an assistant-at-surgery service be reported?
Modifier 50 is inappropriate for this service. CMS also bars assistant-at-surgery payment and does not permit co-surgeons or team surgery.
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.
