Disp fx of 2nd metatarsal bone, l ft, subs for fx w malunion

This code signifies a fracture of the second metatarsal bone in the left foot that has not healed correctly, resulting in a deformity (malunion). This specific encounter is for ongoing treatment or follow-up of this previously sustained and improperly healed fracture.

Apply this code when documenting a patient presenting for management of a malunited fracture of the left second metatarsal. This includes scenarios such as surgical correction of the malunion, physical therapy for impaired function due to the malunion, or follow-up appointments to monitor the malunion's impact.

• Ensure documentation clearly states "malunion" and specifies the "left" second metatarsal.
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Always sequence this code with an external cause code if the cause of the original fracture is relevant and known.
