Disp fx of prox phalanx of unsp great toe, 7thK

This code describes a situation where the large toe's first bone, closest to the foot, was broken and the pieces are no longer aligned. Despite previous treatment, the fracture has failed to heal properly, indicating a nonunion. This is being addressed during a follow-up visit.

Use this code for a patient presenting for ongoing management of a previously treated, displaced fracture of the great toe's proximal phalanx that has not united. This would apply to encounters for cast changes, follow-up imaging to assess nonunion, or discussions about surgical intervention for the nonunion.

• Requires a 7th character "K" for subsequent encounter with nonunion.
• Ensure documentation clearly states "displaced" and "nonunion" for the proximal phalanx of the great toe.
• Laterality (left/right) is unspecified with this code; if known, a more specific code should be used.
