CPT® Code 29856

Arthroscopically aided treatment of tibial fracture, proximal (plateau); bicondylar, includes internal fixation, when performed (includes arthroscopy)

The CPT® Code 29856 refers to the arthroscopically aided treatment of a proximal tibial plateau fracture, specifically a bicondylar fracture. This type of fracture occurs at the upper end of the tibia, which is the larger bone in the lower leg, and involves both the medial and lateral condyles. The proximal tibial plateau is crucial as it forms the lower surface of the knee joint and is integral to weight-bearing and joint stability. The procedure utilizes an arthroscope, a specialized instrument that allows for visualization inside the joint, enabling the surgeon to assess the extent of the injury accurately. The treatment may involve internal fixation, which is the surgical stabilization of the fracture using devices such as screws or plates. The approach is minimally invasive, as it includes making small portal incisions over the knee joint to insert instruments and visualize the fracture site. This method allows for a thorough examination and treatment of the fracture while minimizing damage to surrounding tissues. The specific techniques employed during the procedure can vary based on the fracture's configuration, ensuring that the treatment is tailored to the individual patient's needs.
