Disp fx of 5th metatarsal bone, r ft, subs for fx w nonunion

This code signifies a fracture of the fifth metatarsal bone in the right foot that is no longer in its anatomical alignment. Crucially, it indicates that the fracture has failed to heal properly and is currently being managed as a nonunion, meaning the bone fragments have not fused after a reasonable healing period. This specific code is used for follow-up care related to this ongoing nonunion.

Apply this code for patients presenting for subsequent treatment of a previously diagnosed and displaced right fifth metatarsal fracture that has progressed to a nonunion. This includes visits for continued conservative management, evaluation for surgical intervention, or post-operative care related to the nonunion. It is appropriate when the patient is beyond the initial healing phase and the fracture has failed to unite.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify laterality (right foot) and the specific bone (fifth metatarsal).
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
