Nondisp fx of cuboid bone of unsp ft, subs for fx w nonunion

This code signifies a fracture of the cuboid bone in an unspecified foot that has not healed properly (nonunion) and is being treated in a follow-up encounter. The fracture itself is not displaced, meaning the bone fragments are still in their anatomical alignment.

Apply this code for patients presenting for ongoing management of a previously diagnosed nondisplaced cuboid fracture where the bone has failed to unite. This would include scenarios such as follow-up appointments for casting changes, physical therapy, or surgical planning related to the nonunion.

• Ensure documentation clearly states "nonunion" and "nondisplaced" for the cuboid fracture.
• Verify the encounter is for subsequent care, not the initial injury.
• Laterality (left or right foot) is unspecified with this code; if known, a more specific code should be used.
