CPT® Code 28322

The procedure described by CPT® Code 28322 involves the surgical repair of a nonunion or malunion of the metatarsal bones. A nonunion occurs when the fracture fragments fail to heal together after an adequate period, while a malunion refers to a situation where the fragments heal but in an incorrect alignment, leading to potential complications. These complications can include osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement. During the procedure, the original fracture sites of the metatarsal bones are surgically exposed to assess the condition of the nonunion or malunion. The evaluation determines the necessary repair approach, which may involve internal fixation techniques, with or without the use of a bone graft. If a bone graft is indicated, it is harvested and shaped to fit the defect, promoting healing at the fracture site. The procedure aims to restore proper alignment and stability to the metatarsal bones, ensuring optimal recovery and function for the patient.
