Displ trimalleol fx l low leg, subs for clos fx w routn heal

This code signifies a complex fracture involving all three malleoli (medial, lateral, and posterior) of the left ankle, where the bone fragments are not in their anatomical alignment. The patient is currently in a follow-up period for this fracture, which is healing as expected without complications, and the skin over the fracture site remains intact.

Apply this code for patients presenting for routine follow-up appointments, cast changes, or physical therapy during the normal healing phase of a previously diagnosed displaced trimalleolar fracture of the left lower leg. This is appropriate when the fracture is closed and progressing toward recovery without setbacks.

• Ensure documentation specifies "displaced" and "trimalleolar" for the left lower leg.
• Confirm the encounter is for a "subsequent encounter" and that healing is "routine" for a "closed fracture."
• Do not use for initial treatment, nonunion, malunion, or open fractures.
