Oth physeal fx upper end of l femur, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the top of the left thigh bone, which has not healed properly and is being treated in a follow-up encounter. It indicates a persistent separation of the bone fragments at the physeal line, requiring ongoing medical attention.

Use this code when documenting subsequent care for a patient with a previously diagnosed physeal fracture of the upper left femur that has failed to unite. This would apply to office visits, hospital stays, or other encounters where the nonunion is the focus of treatment, such as surgical planning for revision or ongoing conservative management.

• Ensure documentation clearly states "nonunion" and specifies the left femur's upper end.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture type is physeal, not another type of femoral fracture.
