Nondisp fx of lateral end r clavicle, subs for fx w nonunion

This code describes a situation where a patient has a fracture of the outer portion of their right collarbone that was initially nondisplaced, but is now failing to heal properly. This indicates a complication in the bone repair process following the initial injury.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced lateral right clavicle fracture is being evaluated for or treated due to a lack of bony union. This would include visits for ongoing management, imaging to assess healing progress, or planning for interventions related to the nonunion.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter.
• Verify the fracture location is the "lateral end" of the clavicle and on the "right" side.
• Confirm the initial fracture was "nondisplaced" to accurately select this specific subcategory.
