Post disp fx of sternal end l clavicle, 7thK

This code describes a fracture of the sternal end of the left clavicle that has shifted backward and is not healing properly. It indicates that the patient is presenting for ongoing treatment of this specific fracture, which has failed to unite.

Use this code for follow-up encounters when a patient with a previously diagnosed posterior displaced fracture of the sternal end of the left clavicle is being treated for a nonunion. This includes visits for cast changes, medication management, or surgical planning related to the nonunion.

• Ensure documentation clearly specifies "posterior displaced" and "sternal end" of the left clavicle.
• Confirm the encounter is for a nonunion, not routine healing or initial treatment.
• Always sequence this code after the primary reason for the encounter if applicable.
