LeFort III fracture, subs for fx w delay heal

This code signifies a LeFort III fracture, also known as craniofacial disjunction, which is a complete separation of the midface from the cranial base. It indicates that the patient is receiving follow-up care for this severe facial fracture, and the healing process is progressing slower than expected.

Apply this code for patients presenting for ongoing management of a previously diagnosed LeFort III fracture where the physician documents delayed union or non-union. Documentation should clearly state the LeFort III classification and explicitly mention the delayed healing status during a subsequent encounter.

• Ensure documentation specifies "subsequent encounter" and "delayed healing" for accurate code assignment.
• Distinguish from initial encounters (S02.413A) or encounters for routine healing (S02.413D).
• Always review the entire medical record to confirm the specific LeFort fracture type (I, II, or III) as they have distinct code assignments.
