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

This code signifies a displaced fracture of the cuboid bone in an unspecified foot that has healed incorrectly, resulting in a malunion. The patient is currently undergoing active treatment for this previously sustained fracture and its complication.

Apply this code when a patient presents for follow-up care, physical therapy, or surgical intervention specifically addressing a cuboid fracture that has healed in an anatomically incorrect position. This indicates the fracture has united, but with deformity.

• Ensure documentation specifies "malunion" and that the fracture is displaced.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• If the specific foot (left or right) is documented, a more specific code should be used.
