CPT® Code 28455

Closed treatment of a tarsal bone fracture, specifically excluding the talus and calcaneus, involves a procedure where the fractured bone is treated without the need for surgical exposure. The tarsal bones in question include the cuboid, navicular, and three cuneiform bones. In cases where multiple tarsal bones are fractured, each fracture is reported separately to ensure accurate coding and billing. Prior to treatment, radiographs are obtained to confirm the presence of the fracture. A thorough neurovascular examination is conducted to assess the integrity of the nerves and blood vessels surrounding the injury site. The procedure differentiates between nondisplaced fractures, which may require less intervention, and displaced fractures, which necessitate manipulation to realign the bone fragments. For nondisplaced fractures, as indicated by CPT® Code 28450, treatment may involve immobilization with a cast or brace without the need for manipulation. In contrast, CPT® Code 28455 pertains to the treatment of displaced fractures, where the fractured fragments are manually manipulated back into their proper anatomical position. Following the manipulation, additional radiographs are taken to confirm that the bone fragments are correctly aligned before applying a cast or brace for immobilization during the healing process.
