Displ seg fx shaft of r tibia, 7thN

This code signifies a complex injury involving a displaced fracture that breaks the shaft of the right tibia into multiple segments. It specifically indicates an open fracture (where the bone has broken through the skin) classified as Type IIIA, IIIB, or IIIC, and further complicated by a nonunion, meaning the fracture has failed to heal after a previous treatment.

This code is appropriate for use in follow-up encounters for patients who have previously undergone treatment for a severe open segmental fracture of the right tibia and are now presenting with evidence of nonunion. This includes situations where surgical intervention for nonunion is being planned or performed, or during ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "segmental" and "displaced" for the right tibia shaft fracture.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated in the medical record.
• Confirm that "nonunion" is documented as the current status of the fracture healing.
