Oth fx shaft of unsp fibula, subs for clos fx w nonunion

This code signifies a non-healing fracture located in the shaft of the fibula, where the specific fibula (left or right) is not documented. It indicates that the patient is presenting for follow-up care of a closed fracture that has failed to unite.

Use this code when a patient returns for ongoing management of a fibular shaft fracture that was initially closed, but imaging and clinical assessment confirm nonunion. This applies to situations where the laterality of the fibula is not specified in the medical record.

• Ensure documentation clearly states "nonunion" and specifies the fibula shaft.
• Verify the encounter is for subsequent care, not the initial treatment.
• Only use this code when laterality (left or right) of the fibula is truly unspecified.
