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

This code signifies a non-healing fracture in the upper portion of the right tibia, specifically an open fracture (Type I or II) that is still under active treatment. The "nonunion" indicates that the bone fragments have failed to heal together after a previous injury. This code is used during follow-up care for this specific type of complicated fracture.

Apply this code for patients presenting for subsequent treatment of an open Type I or II fracture of the proximal right tibia that has not united. This includes ongoing management, such as repeat imaging, surgical interventions for nonunion, or conservative treatment aimed at promoting healing. It should be used when the patient is beyond the initial healing phase and the fracture has been identified as non-united.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for an open fracture.
• Verify the fracture location is the "upper end of the right tibia" and not the shaft or distal end.
• Confirm the original fracture was an "open fracture type I or II" as this impacts the specific S82.19_ series.
