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

This code signifies a fracture of the shaft of the left fibula, other than a transverse, oblique, spiral, or comminuted type, that has failed to heal properly. The fracture is closed, meaning the skin remains intact, and the patient is presenting for follow-up care after the initial treatment.

Apply this code when documenting a patient visit for ongoing management of a left fibular shaft fracture that has not united as expected. This would include scenarios where the patient is undergoing further treatment, such as bone grafting or revision surgery, due to nonunion. It is also appropriate for follow-up appointments monitoring the progress of a nonunion.

• Ensure documentation clearly specifies "nonunion" and that the fracture is of the fibular shaft, not the malleolus.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Confirm the fracture is "closed" as indicated in the medical record.
