Unsp fracture of facial bones, subs for fx w delay heal

This code signifies a follow-up encounter for a fracture of an unspecified facial bone that is not healing at the expected rate. It indicates that the initial injury has been treated, but the bone union process is prolonged or complicated.

Use this code when a patient presents for ongoing management of a facial bone fracture (e.g., mandible, maxilla, zygoma) where the specific bone is not documented, and the healing process is delayed. Documentation should clearly state "delayed healing" or similar terminology for a previously diagnosed facial fracture.

• Requires a seventh character "G" for subsequent encounter with delayed healing.
• Do not use for nonunion or malunion; those have distinct seventh characters.
• Ensure the medical record specifies "unspecified facial bone" if a more precise location is unknown.
