3-part fx surgical neck of l humerus, subs for fx w nonunion

This code signifies a complex fracture involving three distinct parts of the surgical neck of the left humerus. The "surgical neck" is a common site for fractures, located just below the humeral head. The "nonunion" indicates that the bone fragments have failed to heal together after a period of time, despite appropriate treatment efforts.

This code is used for follow-up encounters when a patient with a previously diagnosed 3-part surgical neck fracture of the left humerus is being treated for a nonunion. This includes visits for evaluation of the nonunion, planning for further intervention (e.g., surgery, bone stimulation), or monitoring the progress of nonunion treatment. It is appropriate when the fracture has not healed and the patient is no longer in the initial active treatment phase for the acute fracture.

• Ensure documentation clearly states "nonunion" and specifies the left humerus and surgical neck.
• Verify that the fracture was indeed a 3-part fracture initially, as this detail is crucial.
• This code is for subsequent encounters; an initial encounter for the acute fracture would use a different code.
