Unsp physl fx upper end unsp femur, subs for fx w malunion

This code signifies a physeal fracture (growth plate fracture) of the upper end of the femur that has not healed correctly, resulting in malunion. The specific location within the upper femur is not documented, nor is the laterality (left or right). This code is used for follow-up care after the initial treatment of the fracture.

Use this code when a patient presents for ongoing management of a previously treated physeal fracture of the proximal femur that has healed in an unsatisfactory position. This includes scenarios where surgical correction of the malunion is being considered or performed, or when monitoring the functional impact of the malunion. It is appropriate for any subsequent encounter after the initial treatment phase.

• Ensure documentation clearly states "malunion" and that the fracture is of the physis of the upper femur.
• Verify that this is a subsequent encounter, not the initial treatment or routine follow-up without complications.
• If the laterality (left or right) or specific part of the upper femur is known, a more specific code should be selected.
