Oth fx upr & low end l fibula, 7thN

This code describes a non-healing fracture of the upper or lower portion of the left fibula that was initially an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC. The "subsequent encounter" indicates that the patient is receiving ongoing care for this previously diagnosed injury, specifically addressing the failure of the bone to unite.

This code is used when a patient presents for follow-up care of a left fibula fracture that has not healed as expected, and the original injury was a severe open fracture. This would apply to situations where surgical intervention, casting, or other treatments are being continued or modified due to the persistent nonunion.

• Ensure documentation clearly specifies the left fibula and the nonunion status.
• Verify the original fracture was an open fracture of type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
