Nondisp trimalleol fx unsp low leg, 7thR

This code describes a trimalleolar fracture of an unspecified lower leg that was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now experiencing malunion. The fracture itself is currently nondisplaced, indicating that the bone fragments are in their anatomical position despite the malunion. This code is used for subsequent encounters, meaning the initial treatment has already occurred.

Use this code for follow-up encounters when a patient presents with a previously treated open trimalleolar fracture of an unspecified lower leg that has healed in an anatomically incorrect position (malunion), but the fracture fragments themselves are currently aligned. This applies when the original injury was an open fracture classified as Type IIIA, IIIB, or IIIC.

• Ensure the documentation clearly specifies malunion and that the fracture is currently nondisplaced.
• Verify the original injury was an open trimalleolar fracture of Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
