CPT® Code 27846

Ankle dislocation is a significant injury characterized by the displacement of the bones forming the ankle joint, which can occur without any accompanying fractures. This type of dislocation is relatively uncommon but can lead to serious complications, including neurovascular impairment, if not promptly identified and treated. The procedure described by CPT® Code 27846 involves the open treatment of such an ankle dislocation, which may include the use of percutaneous skeletal fixation. During this surgical intervention, a skin incision is made over the ankle joint to allow access to the underlying structures. The surgeon carefully dissects the soft tissues to expose the joint while taking precautions to protect the neurovascular structures that are critical for limb function. Once the joint capsule and ligaments are visualized, they are assessed for integrity. If they are found to be intact, the dislocation is reduced using radiologic guidance, which is a separately reportable service. To stabilize the ankle joint during the healing process, pins may be inserted through the skin and across the joint. This procedure is essential for ensuring proper alignment and stability of the ankle as the surrounding soft tissues recover from the injury.
