LeFort III fracture, sequela

This code signifies a sequela, or late effect, resulting from a LeFort III fracture. A LeFort III fracture, also known as craniofacial disjunction, involves separation of the facial skeleton from the cranial base, often affecting the zygomatic arches, orbits, and nasal bones. Sequelae can include chronic pain, malocclusion, vision impairment, or cosmetic deformities.

Use this code when documenting a condition or complication that is a direct result of a previously sustained LeFort III fracture, and the acute phase of the fracture has passed. Documentation should clearly link the current condition to the prior LeFort III injury, indicating it is a long-term consequence.

• Always sequence this sequela code after the code for the specific late effect being treated (e.g., malunion, nonunion, chronic pain).
• Ensure the medical record explicitly states the condition is a "sequela," "late effect," or "due to prior LeFort III fracture."
• Do not use this code for the initial treatment of an acute LeFort III fracture; instead, use the appropriate acute fracture code.
