Unsp fx shaft of r fibula, 7thM

This code signifies a persistent failure of an open fracture of the shaft of the right fibula to heal, specifically when the initial injury was classified as an open fracture type I or II. "Nonunion" indicates that the bone ends have not united after a sufficient healing period, requiring further intervention.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed open fracture (Type I or II) of the right fibula shaft that has failed to heal. This typically involves ongoing management, evaluation for surgical intervention, or monitoring of a nonunion.

• Ensure documentation clearly states "nonunion" and specifies the initial open fracture type (I or II).
• Verify the fracture location is the shaft of the right fibula.
• This code is for subsequent encounters, not the initial injury.
