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

This code signifies a fracture of the radial head in the left arm that has healed incorrectly, resulting in a deformity (malunion). The fracture was initially displaced, meaning the bone fragments were out of alignment. This code is used when the patient is seen for ongoing management of this malunion, not the initial injury.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a malunited, previously displaced fracture of the left radial head. This includes scenarios where the malunion is causing functional impairment or pain, and the fracture itself is no longer acute. It is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and specifies the left radius.
• Verify that the encounter is for follow-up care of the malunion, not the initial fracture treatment.
• Do not use this code for nonunion, which indicates a complete failure of the bone to heal.
