Oth disp fx of upper end of l humer, subs for fx w nonunion

This code signifies a displaced fracture of the upper portion of the left humerus, excluding the surgical neck, anatomical neck, or epiphyseal plate, that has failed to heal properly. The patient is presenting for follow-up care or treatment related to this unhealed fracture.

Use this code when a patient with a previously diagnosed and treated displaced fracture of the upper left humerus (not surgical neck, anatomical neck, or epiphyseal) is seen for ongoing management of a nonunion. This applies to situations where the fracture fragments have not united after an expected healing period, requiring further intervention or monitoring.

• Ensure documentation clearly states "nonunion" and specifies the "left humerus" and "upper end" location, excluding surgical/anatomical neck or epiphyseal plate.
• Confirm this is a "subsequent encounter" for the fracture; initial treatment or routine follow-up for a healing fracture would use a different seventh character.
• Always review the operative report or physician's notes for details on displacement and the specific part of the upper humerus affected.
