CPT® Code 27722

The CPT® Code 27722 refers to the surgical procedure for the repair of nonunion or malunion of the tibia, specifically utilizing a sliding graft technique. A nonunion occurs when the fracture fragments fail to heal together after an adequate period, while a malunion is characterized by improper alignment of the fracture fragments, leading to potential complications such as bone deformities, joint surface incongruities, soft tissue contractures, and nerve impingements. In this procedure, the surgeon exposes the original fracture site on the tibia to assess the condition of the nonunion or malunion and determine the appropriate repair method. Unlike CPT® Code 27720, which addresses similar issues without the use of a graft, this code involves the application of a sliding bone graft, typically indicated for malunion cases. The surgical approach includes cutting the tibia to allow for the repositioning of bone segments into their correct anatomical alignment, followed by the application of internal fixation devices to stabilize the fracture and ensure proper healing. This procedure is critical for restoring the structural integrity of the tibia and facilitating the healing process, ultimately improving the patient's functional outcomes.
