Unsp fx unsp femur, subs for opn fx type I/2 w malunion

This code indicates a follow-up encounter for an unspecific fracture of the femur, where the initial injury was an open fracture (Type I or II) that has since healed improperly, resulting in malunion. The specific location of the femoral fracture is not documented.

Apply this code when a patient presents for ongoing care or evaluation of a previously sustained open femoral fracture (Type I or II) that has healed in an anatomically incorrect position. This is used during subsequent visits after the initial treatment of the fracture, specifically when malunion is identified and being addressed.

• Ensure documentation clearly states "subsequent encounter" and "malunion" for an open fracture.
• Confirm the original fracture was an open Type I or II; other open fracture types or closed fractures would require a different code.
• This code is used when the specific part of the femur affected by the fracture is not specified in the medical record.
