Disp fx of epiphy (separation) (upper) of l femr, 7thN

This code signifies a displaced fracture of the upper growth plate (epiphysis) of the left femur that has failed to heal properly (nonunion). This specific nonunion is occurring in a fracture that was initially an open fracture of type IIIA, IIIB, or IIIC, and the patient is presenting for follow-up care after the initial treatment.

Use this code for a patient who has previously undergone treatment for an open, displaced epiphyseal fracture of the upper left femur (types IIIA, IIIB, or IIIC) and is now being seen for ongoing management of a documented nonunion. This applies to subsequent encounters where the nonunion is the primary focus of care.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture location is the "upper" epiphysis of the "left" femur.
• This code is for subsequent encounters; an initial encounter would use a different code.
