Nondisp trimalleol fx l low leg, 7thF

This code signifies a fracture involving all three malleoli (medial, lateral, and posterior) of the left lower leg, which remains in its normal anatomical alignment. It specifically indicates that this is not the initial treatment encounter, and the fracture is an open type IIIA, IIIB, or IIIC, currently healing without complications.

Use this code for follow-up visits where a patient with a previously diagnosed nondisplaced trimalleolar open fracture (types IIIA, IIIB, or IIIC) of the left lower leg is being monitored for routine healing. This applies to encounters after the initial definitive treatment, such as cast changes, wound checks, or follow-up imaging demonstrating expected bone consolidation.

• Ensure documentation specifies "nondisplaced" and "trimalleolar" for the left lower leg.
• Verify the encounter is "subsequent" and the open fracture type (IIIA, IIIB, or IIIC) is clearly documented.
• Confirm "routine healing" is indicated; if there are complications (e.g., delayed union, nonunion, infection), a different code would be appropriate.
