Displaced transcondy fx r humerus, subs for fx w nonunion

This code signifies a fracture located across the condyles of the right humerus that has shifted from its normal alignment. 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 displaced transcondylar fracture of the right humerus is seen for treatment or evaluation of a confirmed nonunion. This is appropriate for subsequent encounters after the initial treatment phase, where the primary focus is managing the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the right humerus.
• Verify the fracture is explicitly described as "transcondylar" and "displaced."
• This "K" seventh character indicates a subsequent encounter for a nonunion, not initial treatment or routine healing.
