Displ seg fx shaft of l fibula, 7thM

This code signifies a complex fracture of the left fibula, specifically a segmental break in the shaft where the bone fragments are not properly aligned. It indicates that the patient is in a later stage of care for an open fracture (Type I or II), and the fracture has failed to heal after a reasonable period, leading to nonunion.

This code is appropriate for follow-up encounters where a patient with a previously treated open segmental shaft fracture of the left fibula is diagnosed with nonunion. It should be used when the initial injury was an open fracture of either Type I or Type II, and the current visit addresses the ongoing issue of the fracture not healing.

• Ensure documentation clearly specifies "segmental" and "displaced" for the fibula shaft fracture.
• Verify that the original injury was an "open fracture type I or II" and that the current encounter addresses the nonunion.
• Always sequence this code after the appropriate external cause code, if applicable, for the original injury.
