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

This code signifies a fracture of the shaft of the right fibula, excluding specific types like spiral or transverse, that has not healed properly after an initial treatment. The patient is presenting for follow-up care related to this unhealed fracture, which is currently closed (skin intact).

Apply this code when a patient with a previously diagnosed and treated closed fracture of the right fibula shaft is seen for ongoing management of a nonunion. This includes situations where surgical intervention for the nonunion is being planned or has recently occurred, or when conservative management for the nonunion is ongoing.

• Ensure documentation clearly states "nonunion" and specifies the "right fibula shaft."
• Verify the encounter is for subsequent care of the fracture, not the initial treatment.
• Confirm the fracture is closed; open fractures have different coding pathways.
