Displ transverse fx shaft of unsp fibula, 7thN

This code signifies a non-healing fracture of the fibula's shaft, specifically a transverse break that is no longer in proper alignment. It indicates that the initial injury was an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC), and the patient is now in a later stage of care where the bone has failed to unite.

Use this code for patients presenting for follow-up care, surgical intervention, or ongoing management of a previously treated open fibular shaft fracture that has not healed. This applies when imaging confirms a displaced transverse fracture and the medical record clearly documents nonunion following an initial severe open injury.

• Ensure documentation specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the fibula shaft and is described as "transverse" and "displaced."
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
