Oth fx low end r tibia, subs for opn fx type I/2 w nonunion

This code signifies a non-healing fracture of the lower end of the right tibia, specifically an open fracture that was initially classified as Type I or II. The patient is in a subsequent phase of care, indicating ongoing treatment for the nonunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open fracture (Type I or II) of the distal right tibia that has failed to heal. This includes scenarios where surgical intervention for nonunion is being planned or performed, or during ongoing conservative management for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "right tibia" and "lower end."
• Verify the initial fracture was an "open fracture type I or II" and that this is a "subsequent encounter."
• Do not use for initial fracture treatment or for malunion; a distinct code exists for those scenarios.
