What 15731 covers

A surgeon raises forehead tissue while keeping its blood supply attached, then transfers it to cover a defect, most commonly on the nose. This staged flap is often used by plastic, facial plastic, or otolaryngology surgeons when a nasal defect needs more vascularized tissue than a graft can provide. The flap remains connected to the forehead until a later operation divides and insets it.

Select this code for the forehead flap transfer, based on the flap used and its attached vascular pedicle—not simply because the defect is on the nose. The operative report should identify the donor tissue, recipient defect, and flap transfer. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. 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. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

15731 billing questions

When is this code appropriate for nasal reconstruction?

Use it when the surgeon transfers forehead tissue to the defect while keeping its vascular pedicle attached. The recipient site alone does not determine code selection.

Is division of the flap included in this service?

The initial transfer leaves the flap attached to its forehead blood supply. A later operation to divide and inset a flap at the nose is represented by a separate service, such as 15630 when its descriptor and circumstances fit.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does the 90-day global period affect follow-up billing?

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

Can an assistant surgeon or co-surgeon be billed?

Assistant-at-surgery payment is allowed only when medical necessity is documented. CMS does not permit co-surgeons or team surgery for this code.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.

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.
