Unsp fx head of r femur, subs for opn fx type I/2 w nonunion

This code signifies a non-healing fracture of the femoral head on the right side, which was initially an open fracture (Type I or II). The patient is currently in a subsequent phase of care, indicating ongoing management for the nonunion.

Apply this code for follow-up encounters where a patient is being treated for a right femoral head fracture that has failed to unite, and the initial injury was an open fracture. This would include scenarios such as continued conservative management, planning for revision surgery, or post-operative care for nonunion repair.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the initial fracture was indeed an open fracture (Type I or II) of the right femoral head.
• Do not use this code for initial encounters or for fractures that have healed or are in routine healing.
