3-part fracture of surgical neck of left humerus, init

This code signifies a complex fracture involving three distinct fragments of the surgical neck of the left humerus. This injury typically results from significant trauma and can compromise the blood supply to the humeral head.

Apply this code for the initial treatment of a patient presenting with a closed, three-part fracture of the surgical neck of the left humerus. This includes the initial evaluation, reduction (if performed), and casting or other initial stabilization.

• Ensure documentation clearly specifies a "three-part" fracture and the "surgical neck" location.
• Verify the laterality is "left" and the encounter is "initial" for a "closed" fracture.
• Do not use for open fractures, subsequent encounters, or malunion/nonunion.
