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

This code describes a situation where a patient has a fracture in the upper part of their right humerus that was initially displaced, and during a follow-up visit, it is noted that the bone has healed incorrectly, resulting in a malunion. This indicates a complication of fracture healing where the bone fragments have joined in an abnormal position or alignment.

Use this code for subsequent encounters when documentation confirms a previously displaced fracture of the upper right humerus has healed with a malunion. This is appropriate when the patient is receiving ongoing care for the consequences of the malunion, such as pain, limited range of motion, or planning for corrective surgery. Do not use for initial fracture treatment or for nonunion.

• Ensure documentation explicitly states "malunion" and specifies the "upper end of the right humerus."
• Verify the fracture was initially "displaced" to differentiate from non-displaced fractures.
• This code is for subsequent encounters; an initial encounter code would be used for the acute fracture.
