CPT® Code 29892

Arthroscopically aided repair of large osteochondritis dissecans lesion, talar dome fracture, or tibial plafond fracture, with or without internal fixation (includes arthroscopy)

The procedure described by CPT® Code 29892 involves an arthroscopically aided repair of significant osteochondritis dissecans lesions, talar dome fractures, or tibial plafond fractures. Osteochondritis dissecans is a condition characterized by the separation of a fragment of bone along with the overlying cartilage from the underlying bone, often occurring in the ankle joint. This separation can lead to the formation of loose bodies within the joint or result in cracks in the bone without complete detachment. The talar dome refers to the rounded upper surface of the talus bone, which articulates with the tibia and fibula, while the tibial plafond, also known as the tibial pilon, is the weight-bearing surface at the distal end of the tibia. The procedure is performed using arthroscopy, a minimally invasive surgical technique that allows for direct visualization of the joint through small incisions. The leg is positioned to facilitate access to the ankle joint, and the procedure may involve the use of internal fixation methods, such as wires, pins, or screws, to stabilize the affected area. Additionally, bone grafting may be necessary depending on the extent of the lesion or fracture, ensuring proper healing and restoration of joint function.
