What 49255 covers

The surgeon removes omental tissue, the fatty peritoneal apron that hangs from the stomach and overlies abdominal organs. General surgeons and gynecologic oncologists may perform an omentectomy during abdominal surgery for disease involving the omentum, including malignancy. The operative report should identify the tissue removed and the reason for resection, and distinguish this work from a larger procedure that already includes omentectomy.

Report 49255 when the omental resection is separately reportable, not merely an inherent part of a more comprehensive operation. Documentation should describe the operative work and specimen. 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% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

49255 billing questions

When should 49255 be reported separately?

Report it when the surgeon performs a distinct omental resection that is not already included in a more comprehensive procedure. The operative note should support the separate work.

Can modifier 50 be used for removal of both sides of the omentum?

No. The anatomy and descriptor make bilateral adjustment inappropriate; do not append modifier 50.

How does the multiple-procedure rule affect payment?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.

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.
