Disp fx of lateral malleolus of l fibula, 7thQ

This code describes a left fibular fracture, specifically involving the lateral malleolus, which is out of its normal alignment. It indicates that the fracture was initially an open fracture of Gustilo type I or II, and during a subsequent encounter, the bone has healed incorrectly, resulting in a malunion.

This code is used when a patient presents for follow-up care of a previously treated open fracture of the left lateral malleolus, and imaging or clinical assessment confirms that the bone has healed in an anatomically incorrect position. This would apply to situations such as ongoing physical therapy, pain management, or evaluation for corrective surgery due to the malunion.

• Ensure documentation clearly specifies "left" fibula and "lateral malleolus."
• Verify the original fracture was an "open fracture type I or II" and that the current encounter addresses a "malunion."
• Do not use this code for initial treatment or for nonunion; a malunion implies some degree of healing, albeit incorrect.
