Nondisp transverse fx shaft of unsp fibula, 7thM

This code describes a fibular shaft fracture that runs straight across the bone, without any displacement of the bone fragments. It specifically indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or Type II severity, and that the bone has failed to heal properly in a subsequent encounter.

Use this code when documenting a patient presenting for follow-up care of a previously treated open transverse fibular shaft fracture (Type I or II) where nonunion has been identified. This applies to situations where the fracture is not healing as expected, requiring further intervention or prolonged management.

• Ensure documentation clearly specifies "nondisplaced" and "transverse" morphology of the fibular shaft fracture.
• Verify the original injury was an "open fracture type I or II" and that the current encounter is for "nonunion."
• Do not use for initial treatment or for closed fractures, displaced fractures, or other fracture types.
