Unsp fracture of unsp femur, subs for clos fx w malunion

This code signifies a follow-up encounter for a patient who sustained a fracture of the femur, where the specific location of the fracture within the femur was not documented. The fracture has healed in an imperfect alignment (malunion) and was initially treated as a closed fracture (skin intact).

This code is appropriate for use when a patient presents for ongoing management or evaluation of a previously treated, unspecified femoral fracture that has resulted in malunion. It should be used during subsequent visits after the initial treatment of the fracture, and when the fracture was not open.

• Ensure documentation clearly states "malunion" and that the encounter is not for initial fracture care.
• Verify that the fracture was closed and the specific site of the femoral fracture is not specified in the medical record.
• Always sequence this code after the primary diagnosis for the current encounter, if applicable.
