What 15600 covers

Surgeons use 15600 for a planned reconstructive flap procedure on the trunk when the flap is surgically delayed to encourage dependable blood supply before later use, or when a previously transferred flap is divided and inset. Trunk sites include the chest, abdomen, and back. Plastic and reconstructive surgeons typically perform the work in an operating room, often as one stage of reconstruction after tissue loss or excision.

Choose the code by the flap’s trunk location and the actual delay or division-and-inset work, not by flap size or diagnosis. Document the staged plan, site, and operative steps. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur 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 for this code. An assistant at surgery is paid only when medical necessity is documented; 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.

15600 billing questions

When should I choose 15600 instead of a flap-transfer code?

Use 15600 for delay of a trunk flap or its division and inset. A transfer code describes flap transfer work rather than these stages.

Does 15600 include the later flap transfer?

No. The code describes delay or division and inset on the trunk; the later transfer is a distinct operative stage.

Can I append modifier 50 for flaps on both sides of the trunk?

No. CMS identifies the bilateral adjustment as inappropriate for this descriptor and anatomy.

What documentation supports reporting 15600?

Record the trunk site, whether the surgeon performed a delay or division and inset, and the operative steps supporting that stage of reconstruction.

How does the global period affect postoperative visits?

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

Can an assistant or another surgeon be reported?

Assistant-at-surgery payment requires documented medical necessity. Co-surgeons and team surgery are 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.
