What 44312 covers
A surgeon revises an established ileostomy to correct a local stoma problem, such as retraction or stenosis. The operation is generally performed by a general or colorectal surgeon in a hospital or other surgical setting. This code is for a simple revision; a more extensive revision involving bowel resection is distinguished from it by the operative work performed.
Report the code when the operative note supports revision of an existing ileostomy and describes the problem and corrective technique. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

No. This code describes revision of an existing ileostomy. Code 44310 describes ileostomy or jejunostomy creation.
What should the operative note document?
Document the existing ileostomy, the problem being corrected, the revision performed, and the extent of the work, including whether bowel resection was required.
