Disp fx of lateral malleolus of r fibula, 7thN

This code signifies a fracture of the outer ankle bone (lateral malleolus) of the right fibula that is not properly aligned. It specifically applies to an open fracture, meaning the skin was broken, and the fracture is now failing to heal (nonunion) during a follow-up visit. The "IIIA, IIIB, or IIIC" indicates the severity of the open wound.

This code is used for patients presenting for ongoing treatment of a right lateral malleolus fracture that was initially open and is now complicated by nonunion. This would typically be seen in orthopedic or wound care clinics during subsequent encounters after the initial injury and treatment. It's appropriate when documentation clearly states the fracture is displaced and has not healed.

• Ensure documentation specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the laterality (right fibula) and the specific bone involved (lateral malleolus).
• Confirm this is a "subsequent encounter" and not the initial treatment for the nonunion.
