Reconstructive surgery
About 15758: Free microvascular fascial flap reconstruction
Reports transfer of a free fascial flap with microvascular connection to reconstruct a soft-tissue defect when vascularized fascia is required.
A surgeon harvests fascia as a free flap, divides its native blood supply, transfers it to a defect, and reconnects its vessels to recipient vessels under microsurgical technique. Plastic and reconstructive surgeons and other surgeons with microsurgical expertise may perform the procedure, commonly in an operating room for reconstruction after trauma, tumor removal, or another defect requiring vascularized fascial tissue. The code distinguishes fascia-only tissue transfer from free flaps that include skin or muscle.
Select this code when the operative record supports transfer of a free fascial flap and microvascular anastomosis; document the tissue transferred, recipient site, and vascular connection. It has a 90-day global period that includes the day-before preoperative visit and related postoperative care during that period. 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. Bilateral adjustment is not appropriate. Assistant-at-surgery payment may be allowed, co-surgeons are permitted, and team surgery is not permitted.

15758 billing questions
How is 15758 distinguished from 15756 or 15757?
Use 15758 for a free fascial flap. Codes 15756 and 15757 describe free flaps with muscle or skin, respectively, rather than fascia alone.
What operative details support reporting 15758?
Document the fascial tissue transferred, the defect reconstructed, and the microvascular connection to recipient vessels. The record should establish that this was a free flap, not a graft or a flap that remained attached to its original blood supply.
Can 15758 be reported with another procedure in the same session?
Other procedures may be reported when separately supported. Under the CMS multiple-procedure rule, the highest-valued procedure is paid in full and other procedures performed in the same session are subject to a 50% reduction.
Which surgical-role modifiers may apply?
CMS permits assistant-at-surgery payment and co-surgeons for this code, but does not permit team surgery. Bilateral adjustment does not apply, so modifier 50 is inappropriate.
What care is included in the global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
