Nondisp fx of cuboid bone of l foot, subs for fx w nonunion

This code describes a fracture of the cuboid bone in the left foot that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing care for this fracture, and it has failed to heal properly after the expected time frame.

This code is appropriate for follow-up visits where a patient with a previously diagnosed nondisplaced left cuboid fracture is being treated for a nonunion. This would include evaluations, imaging, or interventions aimed at promoting healing or managing complications of the nonunion.

• Ensure documentation clearly states "nonunion" for the cuboid fracture.
• Verify the laterality (left foot) and displacement (nondisplaced) are explicitly documented.
• Do not use this code for the initial treatment of the fracture; use the appropriate initial encounter code.
