Disp fx of lateral end of l clavicle, subs for fx w nonunion

This code signifies a fracture of the outer portion of the left collarbone that has shifted out of alignment and has failed to heal properly. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment of the fracture. "Nonunion" specifies that the bone fragments have not united after a sufficient healing period.

Use this code when a patient presents for ongoing management of a previously treated displaced lateral clavicle fracture on the left side that has not achieved bony union. This would include scenarios such as evaluation for surgical intervention for nonunion, or conservative management of a confirmed nonunion.

• Ensure documentation clearly states "nonunion" and specifies the lateral end of the clavicle.
• Verify the encounter is for follow-up care, not the initial treatment.
• Confirm laterality as left; a separate code exists for the right side.
