Disp fx of 5th metatarsal bone, l ft, subs for fx w nonunion

This code signifies a fracture of the fifth metatarsal bone in the left foot that is no longer in its anatomical alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for documenting subsequent encounters for a patient with a previously diagnosed displaced left fifth metatarsal fracture that has developed a nonunion. This includes visits for continued management, evaluation of nonunion treatment, or preparation for further intervention. It would not be used for the initial injury or for a fracture that is healing normally.

• Ensure documentation clearly states "nonunion" and "displaced" for the left fifth metatarsal.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion.
• Do not use for malunion; a different seventh character would apply.
