Summary & Overview
CPT 45910: Manual Dilation of Rectal Stricture
CPT code 45910 identifies a manual dilation of a rectal stricture performed with the patient under anesthesia other than local anesthetic. This procedure is clinically important for relieving obstructive symptoms from rectal strictures arising from surgical scarring, radiation, inflammatory disease, or other causes. It represents a targeted, often short-duration surgical intervention that can restore bowel function and reduce the need for more extensive reconstructive procedures.
Key national payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and coding interpretation can influence authorization requirements, site-of-service determination, and payment amounts across these payers.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old who presents with progressive obstructive defecation, intermittent pelvic pain, and a history of rectal stricture following prior anorectal surgery and radiation therapy. Conservative measures including stool softeners, topical therapy, and serial outpatient dilations have failed to provide sustained relief. After preoperative evaluation and informed consent, the patient is scheduled for manual rectal dilation under general or regional anesthesia in an ambulatory surgery center or hospital operating room.
The clinical workflow includes preoperative bowel preparation as indicated, anesthesia evaluation, and intraoperative positioning in lithotomy. The surgeon performs a digital and instrument-assisted manual dilation of the rectal stricture to a therapeutic diameter, assesses mucosal integrity, and documents tissue response. Hemostasis is confirmed; no resection or endoscopic instrumentation beyond manual dilation is performed. Postoperative recovery includes pain control, observation for bleeding or perforation, and discharge with instructions for stool management and follow-up proctologic or colorectal clinic visits.
