Oth nondisp fx of upper end r humer, subs for fx w nonunion

This code signifies a fracture at the top of the right humerus that is not displaced, meaning the bone fragments remain in their normal anatomical alignment. The "nonunion" aspect indicates that the fracture has failed to heal completely after a typical healing period, and this encounter is for ongoing management of that nonunion.

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed, nondisplaced fracture of the upper right humerus that has not healed. This includes scenarios where surgical intervention for the nonunion is being planned or has already occurred, or when conservative management of the nonunion is ongoing.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the fracture is specifically of the "upper end" and on the "right" side.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
