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

This code signifies a fracture of the cuboid bone in the right foot that has shifted out of its normal alignment, and the bone fragments are failing to heal together properly after an initial treatment. This nonunion indicates a complication in the healing process, requiring further medical intervention.

This code is appropriate for documenting follow-up encounters for a patient with a previously diagnosed and treated displaced right cuboid fracture where imaging or clinical assessment confirms that the bone has not united. It is used when the patient is receiving active treatment for the nonunion, such as surgical intervention or prolonged immobilization.

• Requires a seventh character of "K" for subsequent encounter with nonunion.
• Ensure documentation clearly states "displaced" and "nonunion" for the right cuboid fracture.
• Do not use for initial encounters or for fractures that are healing normally.
