Nondisp oblique fx shaft of unsp fibula, 7thM

This code describes a fracture of the fibular shaft that is angled (oblique) and has not shifted out of alignment. It specifically indicates that the fracture was initially an open fracture of type I or II, and the patient is now being seen for ongoing management due to the bone failing to heal properly (nonunion).

Use this code for follow-up encounters where a patient with a previously open (Type I or II) oblique fibular shaft fracture is being treated for nonunion. This applies when the fracture remains nondisplaced. This code is appropriate for subsequent visits for cast changes, wound care related to the nonunion, or evaluation of nonunion treatment.

• Ensure documentation clearly states "nonunion" and specifies the initial open fracture type (I or II).
• Verify the fracture is of the fibular shaft, is oblique, and remains nondisplaced.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
