Oth fx unsp femur, subs for opn fx type I/2 w nonunion

This code signifies a fracture of the femur, not otherwise specified, that is currently experiencing nonunion. The initial injury was an open fracture, classified as Type I or II, and the patient is now in a subsequent phase of care for this ongoing complication.

Apply this code when a patient presents for follow-up care, treatment, or evaluation of a previously sustained open femoral fracture (Type I or II) that has failed to heal properly. This includes situations where surgical intervention for nonunion is being planned or has already occurred, or during ongoing conservative management for the nonunion.

• Ensure documentation clearly specifies "nonunion" as the current complication of the fracture.
• Verify the original fracture was an open fracture, specifically Type I or II, as per Gustilo-Anderson classification.
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing treatment or follow-up after the initial healing phase.
