CPT® Code 27766

The medial malleolus is a critical anatomical structure located at the distal end of the tibia, which is the larger of the two bones in the lower leg. This bony prominence is situated on the inner aspect of the ankle and plays a vital role in the stability and function of the ankle joint, as it articulates with the talus bone. A fracture of the medial malleolus can occur due to various traumatic events, such as falls or sports injuries, leading to pain, swelling, and impaired mobility. The open treatment of a medial malleolus fracture, as described by CPT® Code 27766, involves a surgical procedure where an incision is made directly over the fracture site. This allows the surgeon to access the fractured bone, clear any debris, and manipulate the fracture back into its proper alignment. If necessary, internal fixation devices, such as screws or a plate and screw system, are utilized to stabilize the fracture and promote healing. Following the fixation, the surgical site is thoroughly irrigated to reduce the risk of infection, and the incisions are then closed to complete the procedure. This comprehensive approach ensures that the fracture is properly treated, facilitating recovery and restoring function to the ankle joint.
