CPT® Code 20932

Add-On Code

Allograft, includes templating, cutting, placement and internal fixation, when performed; osteoarticular, including articular surface and contiguous bone (List separately in addition to code for primary procedure)

The CPT® Code 20932 refers to the procedure involving the insertion of an allograft, which is a graft of tissue obtained from a donor (often a cadaver) that is used to reconstruct a bone or soft tissue deficit. This procedure is particularly relevant in cases where there is a need to address significant bone loss due to various conditions such as tumors, osteochondral cysts, posttraumatic or degenerative arthritis, traumatic injuries, or avascular necrosis. The goal of using an allograft is to avoid limb amputation and to preserve the function of the limb by restoring the structural integrity of the affected area. The allograft itself typically consists of bone, cartilage, or other tissues that are anatomically similar to the tissue being replaced. During the procedure, the surgeon accesses the joint or bone area, resecting the damaged tissue down to viable healthy bone or tissue. The allograft is then sculpted to match the shape and size of the removed tissue, using the excised material as a template. Once shaped, the allograft is inserted into the prepared site and secured in place using various fixation methods, which may include rods, cerclage wires, intramedullary nails, plates, or screws. This procedure can involve either a partial or complete intercalary allograft, depending on the extent of the bone loss. The use of this code is essential when billing for the allograft procedure, as it is listed separately in addition to the primary procedure code for radical resection of the diseased bone or joint or for implant removal.
