Disp fx of 3rd metatarsal bone, l ft, subs for fx w nonunion

This code signifies a left foot third metatarsal fracture that is no longer in its anatomical alignment and has failed to heal properly after an initial treatment attempt. The patient is currently receiving care for this ongoing complication, which may involve further intervention to promote bone union.

Apply this code when documenting a patient presenting for follow-up care of a previously diagnosed and treated displaced fracture of the left third metatarsal, where imaging or clinical assessment confirms nonunion. This is appropriate for subsequent encounters focused on managing the nonunion, such as evaluating treatment options or monitoring progress after a new intervention.

• Ensure documentation clearly specifies "left foot" and "third metatarsal" to support this specific code.
• Verify that the encounter is for a subsequent visit addressing the nonunion, not the initial fracture treatment.
• Always pair with an external cause code if the fracture was due to an external event.
