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

This code indicates a fracture of the growth plate (physis) at the lower end of the femur, where the specific location or type of fracture is not documented. It signifies that the patient is presenting for follow-up care of this fracture, and it has healed improperly, resulting in a malunion.

Use this code when documentation confirms a physeal fracture of the distal femur that is not further specified, and the patient is being seen for ongoing management of a malunion. This applies to subsequent encounters after the initial treatment, where the fracture has united but in an unsatisfactory position.

• Ensure documentation explicitly states "malunion" for a subsequent encounter.
• Verify that the fracture site is the lower end of the femur and the type of physeal fracture is unspecified.
• Do not use for nonunion; a different code would be appropriate for that complication.
