Nondisp trimalleol fx l low leg, 7thR

This code describes a situation where a patient has a malunion of a previously sustained trimalleolar fracture of the left lower leg. The original fracture was nondisplaced and was an open fracture of type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This code is used during the healing phase after initial treatment, when the fracture has healed in an unsatisfactory position.

Use this code for follow-up encounters when a patient presents with complications of a left trimalleolar fracture, specifically when imaging confirms malunion. This applies when the original injury was an open fracture with extensive soft tissue involvement (Gustilo-Anderson type IIIA, IIIB, or IIIC). It is appropriate for ongoing management, evaluation for corrective surgery, or monitoring of the malunion.

• Ensure documentation clearly specifies "malunion" and the "left" lower leg.
• Verify the original fracture was an "open" trimalleolar fracture, specifically Gustilo-Anderson type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
