Oth fx shaft of r femur, subs for opn fx type I/2 w nonunion

This code signifies a persistent failure of a previously treated open fracture (Type I or II) of the shaft of the right femur to heal properly. The fracture has not united, indicating a complication in the bone's healing process.

Apply this code when documenting a patient presenting for ongoing management of a nonunion of an open right femoral shaft fracture (Gustilo-Anderson Type I or II). This is used for encounters following the initial treatment of the fracture, where the nonunion is the primary focus of care.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the fracture was initially classified as an open fracture Type I or II.
• Do not use for initial treatment or malunion; a different code would apply.
