Unsp fx shaft of r tibia, 7thN

This code signifies a persistent failure of a previously treated open fracture of the shaft of the right tibia to heal, specifically when the initial injury involved significant soft tissue damage (Type IIIA, IIIB, or IIIC). It indicates that the patient is receiving ongoing care for this nonunion.

This code is appropriate for follow-up encounters where a patient with a documented nonunion of an open right tibial shaft fracture (initially classified as Type IIIA, IIIB, or IIIC) is being evaluated or treated. This includes visits for monitoring, further surgical planning, or conservative management of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right tibia shaft.
• Verify the original fracture was an open fracture, Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture or nonunion.
