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

This code signifies a fracture of the upper part of the right humerus that is not aligned correctly, and the bone has failed to heal after a previous attempt. It indicates that the patient is receiving ongoing care for this unhealed fracture, which is causing persistent issues.

Use this code when a patient presents for follow-up care, surgical intervention, or other treatment related to a previously diagnosed displaced fracture of the upper right humerus that has not united. This applies to situations where the fracture healing process has stalled or failed, leading to a nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "right humerus" and "upper end."
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Verify laterality (right) and the specific anatomical site (upper end of humerus) are explicitly documented.
