Nondisp bimalleol fx unsp low leg, 7thR

This code signifies a bimalleolar fracture of the lower leg that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has subsequently healed improperly (malunion). The fracture itself is currently nondisplaced, meaning the bone fragments are still in their anatomical alignment despite the malunion.

Use this code for follow-up encounters where a patient is being treated for complications arising from a previously sustained open bimalleolar fracture of an unspecified lower leg, specifically when malunion has occurred. This would apply to situations such as assessing the functional impact of the malunion or planning corrective procedures.

• Ensure documentation clearly specifies "malunion" and the original "open fracture type IIIA, IIIB, or IIIC."
• Verify the fracture is currently "nondisplaced" at the time of the encounter.
• Confirm the encounter is for a "subsequent encounter" for the fracture, not the initial treatment.
