Displ bicondylar fx unsp tibia, subs for clos fx w malunion

This code describes a situation where a fracture involving both condyles of the tibia, which was initially treated without surgery (closed fracture), has healed in an unsatisfactory position (malunion). The patient is presenting for follow-up care related to this previously treated fracture and its current malunion.

Use this code for a patient presenting for an office visit, imaging, or other non-surgical treatment related to a bicondylar tibial fracture that has healed with malunion. This applies when the initial injury is no longer in the acute phase and the focus of care is on managing the consequences of the malunion.

• Ensure documentation clearly states "malunion" and that the encounter is for follow-up care of a closed fracture.
• This code indicates an unspecified tibia; if laterality (left/right) is known, a more specific code should be used.
• Pair with an external cause code if the original injury's cause is relevant to the current encounter.
