Reconstructive surgery
About 15756: Free muscle or myocutaneous flap transfer
Report this service for microsurgical transfer of a free muscle or muscle-and-skin flap to reconstruct tissue defects after cancer surgery, trauma, or other tissue loss.
The surgeon harvests muscle, alone or with overlying skin, and transfers it to a separate recipient site as a free flap. Microsurgical anastomosis reconnects the flap’s blood supply to recipient vessels. Plastic and reconstructive surgeons commonly perform these operations in a hospital operating room to address defects after tumor removal, trauma, or other major tissue loss; the recipient site may be in the head and neck, trunk, or an extremity.
Select this code when the transferred tissue is muscle or myocutaneous and the operation includes free-flap microvascular anastomosis. The operative report should identify the flap tissue, donor and recipient sites, and microsurgical vessel connections. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery and co-surgeon payment may be allowed; team-surgery payment is not permitted.

15756 billing questions
How does this differ from 15757?
15756 is for a free flap containing muscle, with or without skin. 15757 is for a free skin flap with microvascular anastomosis.
When would 15758 be more appropriate?
Use 15758 for a free fascial flap with microvascular anastomosis. Choose 15756 when the transferred flap is muscle or muscle with skin.
Can this be reported for a pedicled flap?
No. This code describes free tissue transfer with microvascular anastomosis. A flap that remains attached to its vascular pedicle may fit a site-specific pedicled flap code instead.
What operative documentation supports 15756?
Document the muscle or myocutaneous tissue transferred, its donor and recipient sites, and the microvascular anastomosis reconnecting the flap’s blood supply.
Can an assistant or co-surgeon be paid for this service?
CMS permits assistant-at-surgery and co-surgeon payment for 15756. Team-surgery payment is not permitted.
How does the 90-day global affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Same-session multiple procedures are subject to the standard reduction, and modifier 50 is inappropriate.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
