Displ seg fx shaft of humer, r arm, subs for fx w nonunion

This code signifies a right humerus shaft fracture that is broken into multiple segments and has displaced, meaning the bone fragments are not aligned. The key clinical aspect here is that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when a patient with a previously diagnosed and treated displaced segmental fracture of the right humeral shaft returns for management of a confirmed nonunion. This would be used for subsequent visits after the initial treatment, focusing on interventions or monitoring related to the persistent nonunion.

• Ensure documentation clearly states "nonunion" for the right humeral shaft fracture.
• Verify the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm the fracture is specifically described as "segmental" and "displaced."
