Disp fx of cuboid bone of left foot, subs for fx w nonunion

This code signifies a fracture of the cuboid bone in the left foot that is no longer in its anatomical position and has failed to heal properly after an initial treatment. The "subsequent encounter" indicates that the patient is receiving ongoing care for this unhealed fracture.

Apply this code when a patient presents for follow-up care, cast changes, physical therapy, or surgical intervention related to a previously diagnosed and treated displaced left cuboid fracture that has not united. This code is appropriate when the provider explicitly documents nonunion of the fracture.

• Ensure documentation clearly states "nonunion" of the fracture, not just delayed healing.
• Verify the laterality (left foot) and the specific bone (cuboid) are accurately documented.
• Pair with appropriate external cause codes if the fracture was due to an injury.
