CPT® Code 27709

An osteotomy of the tibia and fibula involves surgical procedures aimed at correcting deformities or realigning the bones of the lower leg. This procedure can be performed on the shafts of the tibia and fibula, as well as on the distal ends of these bones. The specific type of osteotomy performed is determined by the nature and location of the deformity being addressed. Various techniques may be utilized, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy, each designed to achieve optimal alignment and function of the bones. Prior to the surgical intervention, the physician employs radiographic studies to accurately plan the bone cuts necessary for the procedure. The surgical process begins with an incision over the lower leg, followed by careful dissection of the soft tissues to expose the tibia and fibula. The periosteum, a dense layer of connective tissue surrounding the bones, is elevated to facilitate access. Using specialized instruments such as drills, saws, and osteotomes, the surgeon makes precise cuts in the bone according to the pre-determined configuration. In some cases, bone grafts may be inserted between the cut segments to promote healing and stability. To ensure that the bone edges remain properly aligned, various internal fixation devices, such as pins, screws, or plates, may be utilized. Alternatively, an external fixation device can be applied if necessary. This procedure is specifically coded as CPT® 27709 when both the tibia and fibula are involved in the osteotomy.
