Nondisp Maisonneuve's fx l leg, subs for clos fx w malunion

This code signifies a nondisplaced Maisonneuve's fracture affecting the left leg, which is a specific type of ankle fracture involving a spiral fracture of the proximal fibula with an associated ankle injury. The fracture is currently in a healing phase, but with evidence of malunion, meaning the bone has healed in an incorrect anatomical alignment.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed left Maisonneuve's fracture is being evaluated for healing complications, specifically malunion, and the fracture was treated non-surgically (closed treatment). It should be used when the fracture is no longer acute but still requires ongoing management due to the improper healing.

• Ensure documentation clearly specifies "nondisplaced" and "left leg" for accurate laterality and displacement.
• Confirm the encounter is for a subsequent visit and that malunion is explicitly documented as a complication of the closed fracture.
• Do not use for initial encounters or for fractures that have healed correctly or are still in the acute phase.
