Oth physl fx upper end of unsp femur, subs for fx w nonunion

This code signifies a fracture affecting the growth plate (physis) at the top of an unidentifiable femur, which is currently in a state of nonunion. This means the fracture has failed to heal completely after a previous encounter, and the patient is presenting for ongoing management of this complication.

Apply this code when documenting a patient visit for a previously diagnosed physeal fracture of the proximal femur where the specific side (left or right) is not documented, and the fracture has not united. This is appropriate for follow-up appointments, evaluations for surgical intervention for nonunion, or ongoing conservative management of the nonunion.

• Ensure documentation clearly states "nonunion" as the current healing status of the fracture.
• Verify that the encounter is for a subsequent visit related to the fracture, not the initial injury.
• Confirm the specific side of the femur is not documented to justify the "unspecified" laterality.
