Reconstructive surgery
About 20973: Great toe bone-and-skin graft transfer
Report this vascularized bone-and-skin graft when tissue from the great toe is transferred to reconstruct a defect requiring both components.
The surgeon harvests bone and an attached skin component from the great toe while preserving its blood supply, then transfers the graft to a recipient site and connects its vessels microsurgically. This service is used in reconstructive surgery when the defect calls for vascularized bone together with skin; plastic, reconstructive, or orthopedic surgeons may perform it in an operating room. The great toe donor source distinguishes this graft from similar bone-and-skin grafts taken from the metatarsal or iliac crest.
Select the code based on the graft’s donor site, not the recipient location. The operative report should identify the great toe source, the bone and skin components transferred, the recipient site, and the microvascular work. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 applies to bilateral procedures, paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How is modifier 50 handled for bilateral procedures?
