2-part disp fx of surgical neck of right humerus, sequela

This code signifies a fracture of the surgical neck of the right humerus that has resulted in two distinct bone fragments and is no longer in its acute phase. The displacement indicates that the bone ends are not properly aligned. This diagnosis is used when the patient is presenting for treatment of a complication or late effect directly attributable to the initial fracture.

This code is appropriate for encounters addressing long-term complications or sequelae arising from a previously sustained 2-part displaced surgical neck fracture of the right humerus. Examples include chronic pain, malunion, nonunion, post-traumatic arthritis, or nerve damage directly related to the old injury. It should be used when the initial fracture has healed or is no longer undergoing active treatment for the acute injury.

• Always assign a sequela code when the patient is being treated for a complication or late effect of a healed or past injury.
• Do not use this code for initial or subsequent encounters for active treatment of the acute fracture.
• Consider additional codes for specific complications (e.g., M84.2xx for nonunion, M19.1xx for post-traumatic arthritis) if applicable.
