Disp fx of lateral malleolus of r fibula, 7thK

This code signifies a right-sided fibular fracture, specifically involving the lateral malleolus, that has not healed properly (nonunion) despite initial treatment. The fracture fragments remain out of alignment (displaced). This diagnosis is made during a follow-up visit after the initial treatment for the fracture.

Apply this code for patients presenting for subsequent care of a previously treated, but now complicated, right lateral malleolus fracture. This is appropriate when imaging confirms the fracture remains displaced and shows signs of nonunion, indicating a failure of the bone to mend. This code is used after the initial encounter for the fracture.

• Ensure documentation clearly specifies "right" fibula and "lateral malleolus" to differentiate from other ankle fractures.
• Verify the encounter is for "subsequent care" and that "nonunion" and "displaced" are explicitly documented.
• Do not use for initial fracture treatment or for malunion, which implies healing in an incorrect position rather than failure to heal.
