Disp fx of shaft of left clavicle, subs for fx w nonunion

This code signifies a fracture of the shaft of the left clavicle that was initially displaced, but has failed to heal properly and is now in a state of nonunion. This indicates a subsequent encounter where the patient is receiving ongoing treatment for this unhealed fracture.

Use this code when a patient presents for follow-up care, evaluation, or treatment of a previously diagnosed displaced left clavicle shaft fracture that has not united. This applies to situations where the fracture site shows no signs of healing progression after an appropriate period.

• Ensure documentation clearly states "nonunion" and specifies the "shaft" of the clavicle.
• Verify the laterality is "left" and the initial fracture was "displaced."
• This "K" subsequent encounter seventh character is used for ongoing care of the nonunion.
