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

This code signifies a displaced fracture of the radial head, specifically when the fracture has failed to heal properly (nonunion) and the patient is presenting for follow-up care. The fracture is closed, meaning the skin remains intact over the injury site.

Apply this code when a patient with a previously diagnosed displaced radial head fracture, which has not united, returns for subsequent treatment such as cast changes, physical therapy, or evaluation of the nonunion. It is appropriate for ongoing management of the nonunion of a closed fracture.

• Ensure documentation clearly states "nonunion" and "displaced" for the radial head fracture.
• Verify that this is a subsequent encounter for ongoing care, not the initial treatment.
• Confirm the fracture is closed; open fractures would require a different seventh character.
