Nondisp bimalleol fx unsp low leg, 7thM

This code signifies a bimalleolar fracture of an unspecified lower leg that is not displaced, meaning the bone fragments remain in their normal anatomical alignment. It specifically applies when the fracture was initially an open fracture of type I or II, and the bone has failed to heal properly in a subsequent encounter.

Use this code for follow-up visits where a patient is being treated for a previously diagnosed open bimalleolar fracture (Type I or II) of an unspecified lower leg that has not united. This includes situations where the patient is undergoing continued management for the nonunion, such as further imaging, medication adjustments, or preparation for revision surgery.

• Ensure documentation clearly states "nondisplaced," "bimalleolar," "unspecified lower leg," and "nonunion."
• Verify the original fracture was an open fracture, type I or II, as this is a specific requirement for this code.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would not use this code.
