What 45346 covers
During flexible sigmoidoscopy, the clinician examines the rectum and sigmoid colon and destroys a tumor, polyp, or other lesion endoscopically, such as with laser or electrosurgical energy. This treatment is selected when the lesion is not amenable to removal with hot biopsy forceps, bipolar cautery, or a snare. Gastroenterologists and colorectal surgeons commonly perform it in an endoscopy unit or procedure room.
Report the service when the operative note supports ablation rather than biopsy, snare removal, or another therapeutic technique. Document the lesion treated, its location, the ablation method, and why the chosen approach was used. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Do not append modifier 50; this flexible endoscopic treatment is not a bilateral procedure. CMS does not pay an assistant at surgery for this service, and co-surgeon and team-surgery reporting are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

45346 billing questions
When should this code be chosen instead of a removal code?
Use it when the lesion is ablated rather than removed and is not amenable to hot biopsy forceps, bipolar cautery, or snare removal. The operative note should identify the technique and lesion.
How does this differ from diagnostic flexible sigmoidoscopy?
A diagnostic examination reports the inspection when no ablation is performed. When a lesion is treated by ablation during the examination, report the therapeutic service instead of treating the encounter as diagnostic only.
Can biopsy or another endoscopy be reported on the same date?
CMS endoscopy-family pricing applies when related endoscopies are performed together. Documentation should distinguish any separately performed service; do not report a diagnostic examination merely for the inspection integral to the therapeutic procedure.
Should modifier 50 be appended?
No. This is not a bilateral procedure, so modifier 50 is inappropriate.
What global-period and surgical-assistance rules apply?
The service has a 0-day global period, with same-day preoperative and postoperative care included. CMS does not pay an assistant at surgery, and co-surgeon and team-surgery reporting are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
