Disp fx of coronoid pro of unsp ulna, 7thN

This code signifies a non-healing fracture of the coronoid process of the ulna, where the bone fragments are not properly aligned. It specifically applies to open fractures (where the bone broke through the skin) that are classified as Gustilo-Anderson Type IIIA, IIIB, or IIIC, and the patient is in a subsequent phase of care due to the nonunion.

Use this code when documenting ongoing treatment for a patient with a previously diagnosed displaced open fracture of the coronoid process of the ulna (Gustilo-Anderson Type IIIA, IIIB, or IIIC) that has failed to heal. This would be appropriate for follow-up visits, surgical interventions for nonunion, or other management of the unhealed fracture.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the coronoid process fracture.
• Verify the original injury was an open fracture classified as Gustilo-Anderson Type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter for ongoing management of the nonunion, not the initial treatment.
