Displ oblique fx shaft of unsp fibula, 7thK

This code signifies a fibula shaft fracture that is angled, has shifted out of its normal alignment, and is not healing properly. The patient is in a later stage of treatment for this fracture, which was initially managed without surgery, and the bone fragments have failed to unite.

Apply this code when documentation indicates a patient is presenting for ongoing care of a previously diagnosed oblique fibula shaft fracture that has not healed. This includes situations where the fracture site shows no signs of bony bridging after an appropriate healing period, and the initial treatment was non-surgical.

• Ensure documentation explicitly states "nonunion" for a closed fibula shaft fracture.
• Confirm the fracture is described as "oblique" and "displaced."
• This "K" seventh character indicates a subsequent encounter for a nonunion, not initial treatment or routine follow-up for a healing fracture.
