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

This code describes a situation where a patient has a fracture of the cuboid bone in an unspecified foot that was initially displaced but is now experiencing nonunion. Nonunion indicates that the bone fragments have failed to heal together after a significant period.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed displaced cuboid fracture that has not healed. This includes situations where further intervention, such as surgery or casting, is being considered or performed to address the nonunion.

• Ensure documentation clearly specifies "nonunion" and that the fracture was initially displaced.
• Verify the encounter is for follow-up care related to the fracture, not the initial treatment.
• Confirm the laterality of the foot is not specified in the medical record.
