Unsp fx shaft of r fibula, 7thN

This code signifies a non-healing fracture located in the shaft of the right fibula, which was initially an open fracture classified as type IIIA, IIIB, or IIIC. The patient is currently receiving follow-up care for this complication. "Nonunion" indicates that the bone fragments have failed to heal together after a sufficient period.

Apply this code when documenting subsequent encounters for a patient with a previously diagnosed open fracture (Type IIIA, IIIB, or IIIC) of the right fibular shaft that has progressed to nonunion. This would be used during ongoing treatment, such as surgical intervention for nonunion or continued conservative management.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the encounter is "subsequent" for the nonunion, not the initial treatment of the fracture.
• Confirm the fracture location is the shaft of the right fibula and not another part of the bone or the left side.
