LeFort II fracture, subs for fx w delay heal

This code signifies a LeFort II fracture, which is a midfacial fracture involving the nasal bones, medial orbital walls, and maxillary sinuses, with the fracture line extending through the pterygoid plates. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase, and "delayed healing" specifies that the fracture is not progressing to union at the expected rate.

Apply this code when a patient with a previously diagnosed LeFort II fracture presents for follow-up care, and clinical or radiological evidence confirms that the fracture healing is slower than anticipated. Documentation should clearly state "LeFort II fracture," "subsequent encounter," and explicitly mention "delayed healing" or provide details supporting delayed union.

• Ensure documentation specifies "delayed healing" to differentiate from routine healing (S02.412D) or nonunion (S02.412K).
• Verify the specific LeFort fracture type (I, II, or III) as each has distinct codes.
• Sequence this code as a primary diagnosis when the delayed healing is the focus of the encounter.
