CPT® Code 21310

Deleted

The CPT® Code 21310 refers to the closed treatment of a nasal bone fracture without manipulation. 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. In cases of nasal bone fractures, it is essential to assess the severity of the injury, which is typically done through radiographs that are separately reportable. In the context of code 21310, the fracture is classified as nondisplaced, meaning that the bone fragments have not shifted from their original position, and therefore, no manipulation is necessary to realign them. During the procedure, if there is any nasal bleeding, it is managed through internal packing to control the hemorrhage. This method is crucial as it helps stabilize the area and promotes healing without the need for more invasive interventions. It is important to note that this code is distinct from other related codes, such as 21315, which involves the treatment of minimally displaced fractures requiring reduction, and 21320, which includes stabilization with an external splint. The closed treatment indicated by code 21310 is a straightforward approach to managing nondisplaced nasal fractures, focusing on controlling bleeding and ensuring proper healing without the need for manipulation of the bone fragments.
