Nondisp bimalleol fx unsp low leg, 7thP

This code describes a situation where a patient has a bimalleolar fracture (involving both the medial and lateral malleoli) in an unspecified lower leg that was not displaced at the time of injury. The current encounter is for follow-up care of this fracture, which has healed incorrectly, resulting in a malunion.

Use this code for a patient presenting for ongoing management of a previously diagnosed nondisplaced bimalleolar fracture of an unspecified lower leg that has healed in an anatomically incorrect position. This applies to encounters where the fracture is still considered closed and the malunion is being addressed or monitored.

• Ensure documentation clearly states "nondisplaced" and "bimalleolar fracture" of an unspecified lower leg.
• Verify the encounter is for a "subsequent encounter" and specifically mentions "malunion" of a "closed fracture."
• Do not use if the fracture was displaced, if it's an open fracture, or if the encounter is for initial treatment or routine healing without malunion.
