CPT® Code 27725

The CPT® Code 27725 refers to the surgical procedure for the repair of a nonunion or malunion of the tibia through the creation of a synostosis with the fibula, utilizing any method. A nonunion occurs when the fracture fragments fail to unite after an adequate period of healing, while a malunion is characterized by improper alignment of the fracture fragments, leading to potential complications such as osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement. In this procedure, the original fracture site in the tibia is surgically exposed to assess the condition of the nonunion or malunion. The evaluation determines the appropriate method of repair required to achieve proper alignment and stability. This procedure is distinct from other related codes, such as 27720, which involves internal fixation without a graft, and 27722, which employs a sliding bone graft for malunion treatment. In contrast, CPT® Code 27725 specifically addresses the need to create an osseous union between the tibia and fibula, thereby facilitating the healing process at the tibial fracture site through the use of a bone graft secured with screws, ultimately promoting the fusion of the two bones.
