2-part disp fx of surg nk of r humer, subs for fx w nonunion

This code signifies a fracture of the right humerus at the surgical neck, which is displaced into two distinct fragments. The patient is currently undergoing treatment for this fracture, but it has failed to heal properly, indicating a nonunion.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed two-part displaced surgical neck fracture of the right humerus is being managed for a confirmed nonunion. This includes situations where surgical intervention or other treatments are being pursued to address the nonunion.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify the fracture is explicitly described as a "2-part displaced fracture of the surgical neck" and on the "right humerus."
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
