Disp fx of 3rd metatarsal bone, r ft, subs for fx w nonunion

This code signifies a right foot injury where the third metatarsal bone is broken and the bone fragments are not properly aligned. Crucially, the fracture has failed to heal after an initial treatment, and the patient is presenting for ongoing management of this nonunion.

Apply this code when a patient with a previously diagnosed and treated displaced fracture of the right third metatarsal returns for follow-up care, and imaging or clinical assessment confirms that the bone has not united. This is appropriate for visits related to further treatment planning, such as surgical intervention for nonunion, or ongoing conservative management.

• Ensure documentation clearly states "nonunion" of the fracture.
• Verify the laterality (right foot) and specific bone (third metatarsal) are accurately documented.
• Confirm the encounter is for subsequent care, not the initial treatment of the fracture.
