Disp fx of head of unsp radius, subs for clos fx w malunion

This code signifies a displaced fracture of the radial head, which is the top part of the radius bone in the forearm, that has not healed correctly (malunion). This specific code is used when the patient is presenting for follow-up care of this closed fracture, meaning the skin was not broken at the time of injury.

Apply this code for a patient who is returning for an office visit, imaging, or other treatment related to a previously diagnosed closed, displaced radial head fracture that is now showing signs of malunion. This indicates the fracture fragments have healed in an unsatisfactory position. It is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and that the fracture was "closed" and "displaced."
• Verify this is a subsequent encounter, not the initial treatment.
• Confirm the fracture location is specifically the head of the radius.
