Disp fx of 2nd metatarsal bone, r ft, subs for fx w nonunion

This code signifies a fracture of the second metatarsal bone in the right foot that is no longer in its anatomical alignment. The patient is presenting for follow-up care or treatment of this fracture, which has failed to heal properly, indicating a nonunion.

Use this code for patients presenting with a previously diagnosed, displaced right second metatarsal fracture where imaging or clinical assessment confirms the fracture fragments have not united. This applies to subsequent visits for ongoing management of the nonunion, such as discussions about surgical intervention, cast changes, or monitoring.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the right second metatarsal.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the laterality (right foot) is explicitly stated in the medical record.
