Oth fx low end unsp femr, 7thM

This code signifies a fracture at the lower end of the femur, not otherwise specified, that was initially an open fracture (Type I or II) and is now experiencing nonunion. Nonunion indicates that the bone fragments have failed to heal together after a significant period.

This code is used when a patient presents for follow-up care of a previously treated open fracture of the distal femur that has not healed. It specifically applies to cases where the initial open fracture was classified as Type I or II, and the current encounter addresses the ongoing nonunion.

• Ensure documentation clearly states "nonunion" and specifies the initial fracture was an "open fracture type I or II."
• Verify the fracture location is the "lower end of the femur" but not a more specific condylar or supracondylar fracture.
• Confirm this is a "subsequent encounter" for the fracture care, not the initial treatment.
