Nondisp transverse fx shaft of unsp fibula, 7thN

This code signifies a non-healing transverse fracture located in the shaft of an unspecified fibula, which was initially an open fracture of severe type (IIIA, IIIB, or IIIC). The fracture itself remains in its anatomical position without displacement. This diagnosis indicates that the bone has failed to unite after a previous surgical or non-surgical intervention for the original open injury.

Use this code for follow-up encounters where a patient presents with a previously treated, but now non-united, open transverse fibular shaft fracture. This applies when the initial open fracture was classified as type IIIA, IIIB, or IIIC, and the current imaging confirms nonunion without displacement of the fracture fragments. This code is appropriate for ongoing management of the nonunion, such as planning for revision surgery or continued conservative treatment.

• Ensure documentation clearly specifies "nonunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is transverse and located in the shaft of the fibula, and that there is no displacement.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
