Nondisp seg fx shaft of l fibula, 7thM

This code signifies a specific type of fibula fracture in the left leg, where the bone is broken into segments but remains in its natural alignment. It indicates a subsequent encounter for a previously open fracture (Type I or II) that has unfortunately failed to heal properly, resulting in a nonunion.

Apply this code when documenting follow-up care for a patient with a left fibular shaft fracture that was initially an open injury and is now complicated by nonunion. This would be used during ongoing treatment, such as for surgical intervention to promote healing or for management of the nonunion itself, after the initial acute care phase.

• Ensure documentation clearly specifies "left" fibula and "shaft" involvement.
• Verify the original injury was an "open fracture type I or II" and that "nonunion" is explicitly stated.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
