Oth fx lower end of right femur, subs for clos fx w nonunion

This code signifies a fracture located at the lower end of the right femur, excluding condylar or supracondylar types, that has not healed properly (nonunion). The patient is presenting for follow-up care or treatment related to this unhealed fracture, which was initially a closed injury.

Apply this code when a patient with a previously diagnosed closed fracture of the lower right femur (excluding specific types) returns for ongoing management of a confirmed nonunion. This would include scenarios where surgical intervention for nonunion is being planned or has been performed, or when conservative management for the nonunion is continuing.

• Ensure documentation clearly states "nonunion" and specifies the "lower end" of the right femur.
• Verify the encounter is for subsequent care of the fracture, not the initial treatment.
• Confirm the original fracture was closed; open fractures would require a different seventh character.
