Disp fx of coronoid pro of r ulna, 7thR

This code signifies a displaced fracture of the coronoid process in the right ulna that has developed malunion. It specifically applies to an open fracture (Type IIIA, IIIB, or IIIC) that is currently in a subsequent encounter phase, indicating ongoing treatment or follow-up after the initial injury.

Use this code for patients presenting with a previously diagnosed open fracture of the right ulnar coronoid process that has healed in an anatomically incorrect position (malunion). This is appropriate for follow-up visits where the malunion is being addressed, monitored, or is a contributing factor to ongoing symptoms.

• Ensure documentation clearly specifies "right ulna" and "coronoid process" to support this specific site.
• Verify the "subsequent encounter" status and the presence of "malunion" in the physician's notes.
• Confirm the original injury was an "open fracture" of Type IIIA, IIIB, or IIIC, as this is a specific inclusion criterion.
