Reconstructive surgery
About 20970: Vascularized iliac crest bone and skin graft
Reports transfer of vascularized iliac crest bone with a skin component and microvascular connection, commonly for complex mandibular or other skeletal reconstruction.
This code describes transfer of a vascularized graft containing iliac crest bone and skin, with microsurgical connection of its blood supply at the recipient site. It is used when reconstruction requires both a living bone segment and a skin paddle, such as rebuilding a mandibular defect after tumor removal or major trauma. The reconstructive surgeon harvests and transfers the graft; the work includes obtaining the graft and its microvascular transfer.
Select this code when the graft comes from the iliac crest and includes both bone and skin with microvascular anastomosis; a vascularized bone-only graft or a graft from another listed donor site points to a different code. The operative report should identify the donor site, bone and skin components, recipient defect, and microvascular work. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

20970 billing questions
How is this different from 20956?
20970 describes a vascularized iliac crest graft that includes skin. 20956 is the iliac crest option when the graft is bone without a skin component.
Is graft harvest separately reported?
Obtaining the iliac crest graft is included in this service. The operative documentation should show the donor site and the transferred bone and skin components.
What should the operative report document?
Identify the iliac crest as the donor site, the skin component, the recipient defect, and the microvascular transfer. Those details distinguish this service from bone-only or other-site graft codes.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What happens when this is performed with other procedures?
Under the standard multiple procedure rule, the highest-valued procedure is paid in full and other procedures in the same session are paid at 50%.
Where these rates come from
