Displ bimalleol fx unsp low leg, subs for clos fx w malunion

This code signifies a bimalleolar fracture of the lower leg, where both the medial and lateral malleoli are broken and the bone fragments are not properly aligned. This specific code is used when the patient is receiving follow-up care for a fracture that was initially treated non-surgically (closed reduction) and has healed incorrectly, resulting in a malunion. The exact leg (left or right) is not specified.

Apply this code for patients presenting for evaluation or treatment of complications arising from a previously treated bimalleolar fracture of an unspecified lower leg, where the fracture has healed in an abnormal position. This includes scenarios where the malunion is causing pain, functional limitations, or requires further intervention. It is appropriate for subsequent encounters after the initial treatment phase.

• Ensure documentation clearly states "malunion" and specifies a "bimalleolar fracture."
• Verify that the encounter is for follow-up care of a closed fracture, not initial treatment or open fracture care.
• Do not use this code if the laterality (left or right leg) is documented; instead, choose a more specific code.
