Nondisp spiral fx shaft of unsp fibula, 7thN

This code describes a spiral fracture of the fibular shaft that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates an open fracture (where the bone broke through the skin) of type IIIA, IIIB, or IIIC, and is used for encounters where the fracture has failed to heal (nonunion).

This code is appropriate for follow-up encounters with a patient who previously sustained an open spiral fibula shaft fracture (types IIIA, IIIB, or IIIC) that is now exhibiting nonunion. This would include situations where the patient is undergoing treatment for the nonunion, such as bone grafting or revision surgery.

• Ensure documentation clearly specifies "nonunion" for this subsequent encounter.
• Verify the original fracture was an open fracture of type IIIA, IIIB, or IIIC.
• Do not use for initial encounters or for fractures that are healing normally.
