Nondisp seg fx shaft of r fibula, 7thN

This code signifies a non-displaced fracture affecting a segment of the shaft of the right fibula. It specifically indicates that the fracture is an open fracture of type IIIA, IIIB, or IIIC, and the patient is in a subsequent phase of care where the fracture has failed to heal (nonunion).

Use this code for follow-up encounters when a patient with a previously diagnosed non-displaced segmental open fracture (type IIIA, IIIB, or IIIC) of the right fibula shaft is experiencing nonunion. This applies when the patient is receiving ongoing treatment for the nonunion, such as bone grafting or revision surgery.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is non-displaced and located in the shaft of the right fibula.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
