Nondisp transverse fx shaft of unsp fibula, 7thR

This code describes a fibular shaft fracture that runs horizontally across the bone, has not shifted out of alignment, and is currently healing poorly (malunion). It specifically indicates that the initial injury was an open fracture, meaning the skin was broken, and was classified as a severe type IIIA, IIIB, or IIIC. This code is used during follow-up care for this specific type of complicated healing.

This code is appropriate for documenting follow-up encounters for patients with a previously diagnosed transverse, nondisplaced fibular shaft fracture that was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now exhibiting malunion. It should be used when the patient is receiving ongoing treatment or evaluation for the malunion of this specific fracture.

• Ensure documentation clearly specifies "malunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is transverse and nondisplaced, and located in the shaft of the fibula.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
