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

This code signifies a two-part fracture of the surgical neck of the right humerus that has healed incorrectly, resulting in a malunion. The fracture was displaced at the time of injury, and the patient is currently in a phase of treatment or follow-up for this improperly healed fracture.

Apply this code when documenting a patient presenting for follow-up care, rehabilitation, or further intervention related to a previously treated right humerus surgical neck fracture that has healed with an unacceptable alignment. This is appropriate for subsequent encounters after the initial treatment of the acute fracture.

• Ensure documentation clearly states "malunion" and specifies the right humerus surgical neck.
• Verify the encounter is for follow-up care related to the malunion, not the initial acute treatment.
• Confirm the fracture was a "2-part" and "displaced" type at the time of injury.
