Displ transverse fx shaft of l fibula, 7thN

This code signifies a left fibular shaft fracture that is displaced and has failed to heal properly (nonunion), specifically when the initial injury was an open fracture of type IIIA, IIIB, or IIIC. It indicates that the patient is receiving ongoing treatment for this complicated fracture.

This code is appropriate for subsequent encounters where a patient is being managed for a previously diagnosed displaced transverse fracture of the left fibular shaft that has developed nonunion. This includes follow-up appointments, cast changes, or surgical interventions aimed at promoting healing of the nonunion, provided the original injury was a severe open fracture.

• Confirm documentation specifies "nonunion" and the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• Ensure the encounter is "subsequent" and not the initial treatment for the fracture.
• Verify laterality (left fibula) and the specific fracture type (transverse, shaft, displaced).
