Oth fx upr end unsp tibia, 7thN

This code signifies a non-healing fracture of the upper part of the tibia (shin bone) that is not otherwise specified, meaning the exact location within the upper end isn't detailed. It specifically applies when the initial injury was an open fracture of severe types (IIIA, IIIB, or IIIC), and the patient is presenting for follow-up care due to the fracture failing to unite.

Use this code for patients undergoing ongoing treatment for a previously diagnosed severe open upper tibial fracture that has not healed. This would include scenarios where surgical intervention for nonunion is being planned or has been performed, or during follow-up appointments to monitor the nonunion.

• Ensure documentation clearly specifies "nonunion" and that the initial fracture was an open type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
• Verify that the fracture location is indeed the "upper end of the tibia" but not specific enough for a more precise code.
