CPT® Code 21320

The CPT® Code 21320 refers to the closed treatment of a nasal bone fracture that involves manipulation and stabilization. The nasal bones, which are two small, elongated bones located at the bridge of the nose, are crucial for both structural integrity and aesthetic appearance. They project from the frontal processes of the maxilla and the nasal process of the frontal bone, meeting at the midline of the face. When a fracture occurs, it is essential to assess the severity of the injury through radiographs, which are separately reportable. The procedure begins with the reduction of the fracture, which may involve techniques such as using an elevator to manipulate the bone fragments back into their proper position. This is done by applying outward pressure with the elevator while simultaneously using the thumb to provide counterpressure externally. Alternatively, forceps may be employed to grasp and reposition the displaced bone fragments. After the nasal bones are realigned, the septum is evaluated to ensure proper alignment. Following this, additional radiographs are obtained to confirm that the anatomical reduction has been achieved. To control any bleeding that may occur, internal packing is applied. In the case of CPT® Code 21320, after the reduction is performed as described in the related code 21315, the fracture is further stabilized using both internal packing and an external splint to maintain the correct position during the healing process.
