Nondisp commnt fx shaft of unsp femr, 7thN

This code signifies a comminuted fracture of the femoral shaft that is not displaced, meaning the bone fragments are still in their anatomical position relative to each other. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, which was an open fracture (Type IIIA, IIIB, or IIIC) and has now developed a nonunion, meaning the bone is failing to heal.

Use this code when documenting ongoing treatment for a patient whose previously sustained open comminuted femoral shaft fracture (Type IIIA, IIIB, or IIIC) has failed to unite. This would apply to encounters for surgical intervention for nonunion, cast changes, or evaluation of the nonunion's progress.

• Ensure documentation clearly states "nondisplaced," "comminuted," and "shaft of femur."
• Verify the original injury was an open fracture classified as Type IIIA, IIIB, or IIIC.
• Confirm the current encounter is for treatment of a nonunion, not initial treatment or routine healing.
