CPT® Code 28575

The closed treatment of talotarsal joint dislocation, as described by CPT® Code 28575, involves a specific procedure that requires anesthesia. The talus, one of the seven tarsal bones in the foot, plays a crucial role in the articulation of the ankle joint, connecting superiorly with the tibia and fibula, and inferiorly with the calcaneus and navicular bones. A dislocation of the talotarsal joint is considered a rare but significant injury, affecting the talocalcaneal and/or talonavicular joints. This condition necessitates a thorough evaluation of the neurovascular status of the foot to ensure proper blood flow and nerve function. In cases where a pulse is absent, immediate reduction of the dislocated joint(s) is performed without the need for pre-reduction radiographs. Conversely, if the neurovascular status is intact, separate radiographs are obtained to assess the extent of the dislocation. The reduction process involves applying longitudinal traction to the foot while exerting pressure on the talus, typically with the knee flexed. After the joint is successfully reduced, the neurovascular status is re-evaluated, and a second set of radiographs is taken to confirm the proper alignment. Following the procedure, the foot is immobilized in a splint, and the patient is advised to ice and elevate the foot to aid in recovery. It is important to note that CPT® Code 28570 should be used when the dislocation is treated without anesthesia, while CPT® Code 28575 is specifically designated for cases requiring anesthesia.
