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

This code signifies a fracture of the lower end of the right humerus that is not in its anatomical alignment, and the bone fragments have failed to heal together after an initial treatment. The "subsequent encounter" indicates the patient is receiving ongoing care for this unhealed fracture.

Apply this code when documenting follow-up care for a patient whose previously treated displaced right distal humerus fracture has not united. This includes situations where surgical intervention or other treatments are being considered or performed to address the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "right" humerus and "lower end."
• Verify the encounter is for ongoing treatment of the nonunion, not the initial fracture care.
• Always code with any associated external cause codes and place of occurrence codes, if applicable.
