Nondisp bimalleol fx l low leg, 7thM

This code describes a situation where a patient has a non-displaced fracture involving both the medial and lateral malleoli of the left ankle, which was an open fracture (Type I or II) at the time of injury. The current encounter is for ongoing management because the fracture has failed to heal properly (nonunion).

Use this code for follow-up encounters with a patient who previously sustained an open bimalleolar fracture of the left lower leg, and imaging or clinical assessment confirms that the fracture fragments have not united. This applies when the fracture was initially classified as an open Type I or Type II, and the current treatment focuses on addressing the nonunion.

• Ensure documentation specifies "nondisplaced" and "bimalleolar" for the left lower leg.
• Confirm the original injury was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
