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

This code signifies a fracture of the fourth metatarsal bone in the right foot that was initially displaced but has healed improperly, resulting in a malunion. The patient is currently being seen for ongoing management or complications related to this malunited fracture, not for the initial injury.

Use this code when a patient presents for follow-up care, physical therapy, or surgical intervention addressing a previously treated, displaced right fourth metatarsal fracture that has healed in an anatomically incorrect position. This applies to situations where the malunion itself is the focus of the current encounter.

• Ensure documentation clearly states "malunion" and specifies the "fourth metatarsal" and "right foot."
• Verify that the encounter is for a subsequent visit related to the fracture's healing complication, not the initial treatment.
• Always code laterality (right/left) and the specific bone involved.
