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

This code signifies a left foot fifth metatarsal fracture that was initially displaced but has since healed improperly, resulting in a malunion. The patient is currently receiving care for this specific complication of the fracture.

Apply this code when a patient presents for follow-up care, rehabilitation, or further intervention related to a previously treated, displaced fifth metatarsal fracture of the left foot that has healed in an anatomically incorrect position. This indicates ongoing management of the malunion.

• Ensure documentation clearly states "malunion" and specifies the "left foot" and "fifth metatarsal."
• This code is for subsequent encounters; an initial encounter would use an A or D seventh character.
• Confirm the fracture was originally "displaced" as this is a specific component of the code.
