LeFort III fracture, subs for fx w routn heal

This code signifies a follow-up visit for a LeFort III fracture, which is a complete craniofacial disjunction involving separation of the facial bones from the skull base. At this stage, the fracture is healing as expected without complications. This typically involves ongoing management and monitoring of the healing process.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed LeFort III fracture is undergoing routine follow-up care and the fracture is progressing toward normal healing. Documentation should clearly indicate a LeFort III fracture and specify the encounter as a follow-up for routine healing, often noted in progress notes or discharge summaries.

• Ensure documentation specifies "routine healing" to differentiate from delayed healing (S02.413G) or nonunion (S02.413K).
• This code requires a seventh character "D" for subsequent encounter, indicating active treatment and routine healing.
• Do not use this code for initial treatment of the fracture; use the appropriate initial encounter code (S02.413A).
