What 15610 covers

This code covers a preparatory operation on a flap intended for later reconstruction of an arm or leg. The surgeon surgically alters or partially sections the planned flap so it can develop a more reliable blood supply before transfer. Plastic and reconstructive surgeons commonly perform this staged work in an operating room when a flap is planned for coverage of a traumatic or surgical defect. The later flap transfer is a distinct reconstructive step, not the delay procedure itself.

Report 15610 when the operative record supports flap preparation on an upper or lower extremity, rather than on another anatomic site. Document the flap location, the preparatory surgical work, and its role in the planned reconstruction. The code has a 90-day global period that includes 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 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.

15610 billing questions

When is 15610 selected instead of another flap-delay code?

Use 15610 for flap preparation on an arm or leg. The related delay codes distinguish other anatomic regions, including the trunk, face or neck, and eye, nose, ear, or lip.

Does 15610 report the later flap transfer?

No. It reports the preparatory delay procedure on an extremity flap; the later transfer is a separate reconstructive step.

Can modifier 50 be used when both arms or legs are treated?

No. CMS identifies bilateral adjustment as inappropriate for this code. Report the service according to the applicable coding instructions for the documented procedures.

What documentation supports reporting 15610?

The operative note should identify the extremity site, describe the surgical preparation or sectioning of the flap, and connect that work to the planned reconstruction.

How does the global period affect postoperative visits?

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

When can an assistant-at-surgery be paid?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.

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.
