Displ commnt fx shaft of l fibula, 7thM

This code describes a complex injury involving a displaced, comminuted fracture of the shaft of the left fibula. The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and the bone has failed to heal properly in a subsequent encounter.

This code is used when a patient presents for ongoing treatment of a left fibula shaft fracture that was initially open (Type I or II) and has now developed nonunion. This would apply to follow-up visits, surgical interventions for nonunion, or management of complications related to the unhealed fracture.

• Ensure documentation clearly specifies "left" fibula and "shaft" involvement.
• Confirm the fracture was initially classified as an open Type I or II.
• Verify that the encounter is for nonunion, indicating a failure of the fracture to heal.
