Disp fx of 4th metatarsal bone, l ft, subs for fx w malunion

This code signifies a left foot fourth metatarsal fracture that has healed in an abnormal position (malunion) and is being addressed in a follow-up encounter. The fracture was initially displaced, meaning the bone fragments were not properly aligned at the time of injury.

Apply this code when a patient presents for ongoing management of a previously sustained, displaced fracture of the fourth metatarsal in the left foot, and imaging or clinical assessment confirms malunion. This is appropriate for visits related to evaluating the malunion, planning corrective surgery, or monitoring non-operative management of the malunion.

• Ensure documentation clearly specifies "left foot" and "fourth metatarsal" to support this specific code.
• Verify that the encounter is for a "subsequent encounter" and that "malunion" is explicitly documented as the healing complication.
• Do not use for initial fracture treatment or for nonunion; those require different codes.
