Fx oth skull and facial bones, unspecified side, 7thK

This code describes a fracture of a skull or facial bone (excluding nasal, orbital floor, or malar/maxillary bones) that has failed to heal properly after initial treatment. It indicates a subsequent encounter where the nonunion of the fracture is being addressed or monitored.

Use this code for follow-up visits or ongoing treatment of a previously diagnosed and treated skull or facial bone fracture (other specified types) where the bone fragments have not united. Documentation should clearly state "nonunion" of the fracture and specify the affected skull or facial bone (e.g., frontal, temporal, parietal, sphenoid, ethmoid, vomer, palatine, lacrimal, inferior nasal concha).

• Ensure documentation specifies "nonunion" and not just delayed healing or malunion.
• Do not use for initial encounters; this is a subsequent encounter code.
• Requires an external cause code (e.g., V00-Y99) to describe the cause of the fracture.
