LeFort II fracture, sequela

This code signifies a long-term complication or residual effect stemming from a LeFort II fracture, which is a complex midfacial fracture involving the nasal bones, maxilla, and often the orbital floor. Sequelae can include chronic pain, malunion, nonunion, cosmetic deformities, or functional impairments such as vision problems or difficulty with mastication.

Apply this code when documenting a condition that is a direct consequence of a previously sustained LeFort II fracture, after the acute phase of injury has passed. Documentation should clearly link the current condition to the prior LeFort II fracture, often indicating "due to prior LeFort II fracture" or similar phrasing. This code is appropriate for follow-up care addressing these chronic issues.

• Always sequence the sequela code first, followed by codes for the specific manifestation of the sequela (e.g., chronic pain, malunion).
• Ensure documentation explicitly states the connection between the current condition and the prior LeFort II fracture, not an acute injury.
• Distinguish from acute LeFort II fractures (S02.412A-D) which are used for initial encounters or subsequent encounters during active treatment.
