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.

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.

44312 billing questions

How do I distinguish this from 44314?

Use 44312 for a simple local revision, such as correction of retraction or stenosis. A revision involving bowel resection is associated with 44314.

Can I report this for creating a new ileostomy?

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.

Does the service have a global period?

Yes. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 or an assistant-at-surgery claim be used?

Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity.

How are other procedures in the same session paid?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.

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.
