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

This code signifies a healing fracture of the shaft of the left fibula that is not uniting correctly, resulting in an abnormal alignment of the bone fragments. The fracture itself is closed, meaning the skin over the injury remains intact. This code is used when the patient is receiving follow-up care for this specific complication.

Apply this code when a patient presents for ongoing treatment of a left fibular shaft fracture that has previously been diagnosed as closed, but imaging or clinical assessment now indicates malunion. This would include scenarios such as follow-up appointments for cast changes, physical therapy, or surgical planning to correct the malunion.

• Ensure documentation clearly specifies "malunion" and not just delayed healing or nonunion.
• Verify the fracture is of the "shaft" of the fibula and on the "left" side.
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing care after the initial treatment.
