Oth fx upr & low end r fibula, 7thN

This code signifies a non-healing fracture of either the top or bottom portion of the right fibula, which was initially an open fracture of a severe type (IIIA, IIIB, or IIIC). "Nonunion" indicates that the bone fragments have failed to heal together after a significant period. This code is used when the patient is receiving ongoing care for this specific complication.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed open fracture (Type IIIA, IIIB, or IIIC) of the upper or lower right fibula that has progressed to nonunion. This includes visits for continued monitoring, surgical intervention for nonunion, or management of related complications.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture location is specifically the upper or lower end of the right fibula.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
