About 45910: Rectal stricture dilation under anesthesia
Dilation of a documented rectal stricture under anesthesia other than local, reported when the narrowed rectal segment is mechanically or balloon-expanded.
This service treats a narrowed rectal segment by expanding the stricture, for example with a balloon or other dilation instrument. A colorectal or general surgeon typically performs the procedure in an operating or procedure room with anesthesia beyond local anesthesia. The clinical problem is a rectal narrowing requiring dilation, not simply a tight anal sphincter or a rectal obstruction that is removed.
Report the code when the operative note identifies the rectal stricture and documents its dilation and the anesthesia used. The 10-day global period includes related postoperative visits during that period. If multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

45910 billing questions
How is rectal stricture dilation different from anal sphincter dilation?
Code 45910 is for a narrowing in the rectum. Code 45905 describes dilation directed at the anal sphincter, so the documented site determines the choice.
What documentation supports reporting 45910?
Document the rectal stricture, its location when known, the dilation performed, and anesthesia other than local. The note should distinguish the rectal narrowing from an anal sphincter problem.
Are related postoperative visits separately reported?
Related postoperative visits during the 10-day global period are included in the procedure's payment.
Can modifier 50 be used?
No. The anatomy or descriptor makes a bilateral adjustment and modifier 50 inappropriate for this service.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction. An assistant at surgery is not paid; co-surgeons and team surgery are not permitted.
