About 45320: Rigid proctosigmoidoscopy with lesion ablation
Rigid proctosigmoidoscopy with lesion ablation is reported when a rectal or distal sigmoid lesion requires destruction rather than conventional forceps or snare removal.
During rigid proctosigmoidoscopy, the clinician examines the rectum and distal sigmoid through a rigid scope and destroys a tumor, polyp, or other lesion that is not suitable for removal with hot biopsy forceps, bipolar cautery, or a snare. This is a therapeutic procedure rather than inspection or tissue sampling alone. Gastroenterologists and colorectal surgeons may perform it in an endoscopy unit or operating room, depending on access and the patient's needs.
Report 45320 for the ablation service when the documented lesion and treatment fit this rigid-scope procedure; use a removal code when the lesion is excised instead. The procedure note should identify the lesion, its site, and the ablative treatment. 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. Assistant-at-surgery payment is barred, and co-surgery and team surgery are not permitted.

45320 billing questions
How does 45320 differ from 45308 or 45309?
45320 is for ablation of a lesion not suitable for conventional removal. Codes 45308 and 45309 describe lesion removal using hot biopsy forceps or bipolar cautery, and snare technique, respectively.
How does this code differ from 45346?
Both describe lesion ablation, but 45320 is for rigid proctosigmoidoscopy. Code 45346 describes ablation during flexible sigmoidoscopy.
What should the procedure note document?
Document the lesion's location and the ablative treatment performed, including why the service was ablation rather than conventional forceps or snare removal.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Are same-day care and surgical assistance paid separately?
The 0-day global period includes same-day preoperative and postoperative care. CMS does not pay for an assistant at surgery, and does not permit co-surgeons or team surgery.
What happens when related endoscopies are performed together?
CMS applies endoscopy family pricing when related endoscopies are performed together, rather than pricing each related scope as an entirely independent procedure.
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.
