CPT® Code 27720

The CPT® Code 27720 refers to the surgical procedure for the repair of nonunion or malunion of the tibia without the use of a graft, specifically utilizing a compression technique. A nonunion occurs when the fracture fragments fail to unite after an adequate healing period, 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 for the specific case. The procedure involves the application of internal fixation devices, such as a compression plate, to stabilize the fracture site. For nonunions, a compression plate is affixed over the fracture and secured with lag screws, while for malunions, the tibia may be refractured and realigned, followed by the placement of internal fixation to maintain proper anatomical alignment. After the fixation device is placed, the stability of the fracture is assessed, and alignment is confirmed through radiographic imaging, ensuring that the repair is effective and the bone is positioned correctly for optimal healing.
