CPT® Code 21315

The CPT® Code 21315 refers to the closed treatment of a nasal bone fracture with manipulation, specifically without stabilization. The nasal bones are two small, elongated bones that form the bridge of the nose, projecting from the frontal processes of the maxilla and the nasal process of the frontal bone, and they meet at the midline of the face. When a fracture occurs in this area, it is essential to assess the severity of the injury through separately reportable radiographs of the nasal bones. In the procedure described by code 21315, a minimally displaced nasal fracture is addressed through a reduction technique. This involves the use of an elevator, which is inserted into the nasal cavity to manipulate the depressed fragments back into their proper position. The surgeon applies outward pressure with the elevator while simultaneously using their thumb to exert counterpressure on the outside of the nose, ensuring that the bones are realigned correctly. Alternatively, forceps may be employed to grasp the displaced bone and reposition it to restore anatomical alignment. After the reduction process, the septum is evaluated to confirm that it is also properly aligned. To verify the success of the reduction, additional radiographs are obtained. Finally, internal packing is applied to manage any bleeding that may occur as a result of the manipulation. This procedure is crucial for restoring the structural integrity of the nasal bones and ensuring proper healing without the need for stabilization methods, which are addressed in the subsequent code 21320.
