Fx l shoulder girdle, part unsp, subs for fx w nonunion

This code signifies a fracture affecting the bones of the left shoulder girdle (e.g., clavicle, scapula, or proximal humerus) where the specific bone involved is not documented. Importantly, it indicates that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when a patient with a previously diagnosed, unspecified left shoulder girdle fracture presents for treatment of a confirmed nonunion. This would include scenarios where surgical intervention for the nonunion is being planned or performed, or during ongoing conservative management of the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the left side.
• Only use this code for subsequent encounters after the initial treatment of the fracture.
• If the specific bone of the shoulder girdle is known, a more precise code should be used.
