Nondisp oblique fx shaft of l fibula, 7thN

This code signifies a non-displaced fracture of the shaft of the left fibula, characterized by an oblique break that has not resulted in significant bone displacement. The fracture was initially an open fracture of severe type (IIIA, IIIB, or IIIC), and the current encounter addresses a nonunion, meaning the bone has failed to heal properly.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed severe open oblique fibular shaft fracture (left side, non-displaced) is being treated for a nonunion. This includes situations where surgical intervention or other treatments are being performed to address the failed healing.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the initial fracture was indeed an open fracture type IIIA, IIIB, or IIIC, as this impacts the "N" seventh character.
• Confirm the fracture is of the left fibula shaft and is described as "nondisplaced oblique."
