Unsp physl fx low end humer, l arm, subs for fx w nonunion

This code signifies an unconfirmed growth plate fracture at the distal end of the left humerus that has failed to heal properly. It indicates that the patient is returning for ongoing management or treatment of this specific fracture complication. The "unspecified" nature means the exact type of physeal fracture (e.g., Salter-Harris type) was not documented.

Apply this code when a patient presents for follow-up care of a previously diagnosed, non-healing growth plate fracture of the left distal humerus. This includes situations where surgical intervention for nonunion is being planned or has occurred, or when conservative management for nonunion is continuing. It's crucial that the encounter is for the nonunion itself, not the initial injury.

• Ensure documentation clearly states "nonunion" and specifies the left lower end of the humerus.
• Verify that the encounter is subsequent to the initial treatment of the fracture.
• Do not use if the fracture is healing normally or if the specific Salter-Harris type is known and documented.
