What 15740 covers

The surgeon raises an island of skin with underlying tissue while preserving its vascular attachment, then moves it into a nearby defect. The flap provides tissue for coverage after excision, trauma, or another operation when a graft or simple closure would not adequately reconstruct the site. Plastic, facial plastic, otolaryngology, and hand surgeons may perform this procedure in an operating room or, for selected cases, an office procedure setting.

Report the code when the operative note supports transfer of an island flap on a subcutaneous vascular pedicle, rather than a free flap or a different named pedicle flap. Documentation should identify the defect, flap design and tissue transferred, preserved pedicle, and how the flap was inset. CMS 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. CMS restricts assistant-at-surgery payment and does not permit co-surgeons or team surgery for this code.

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.

15740 billing questions

How is an island pedicle flap different from local tissue rearrangement?

Use 15740 when the operative technique transfers an island of tissue on an attached vascular pedicle. Local tissue rearrangement codes describe a different advancement, rotation, or transposition approach.

When would 15750 be a better choice?

Compare the operative technique and the type of pedicle documented. 15750 describes a neurovascular pedicle flap; 15740 describes an island flap carried on its vascular pedicle.

Can modifier 50 be appended for flaps on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code’s descriptor or anatomy.

Does the code include related postoperative visits?

Yes. 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?

CMS applies a statutory restriction on assistant-at-surgery payment for 15740 and does not permit co-surgeons or team surgery.

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.
