Disp fx of 2nd metatarsal bone, unsp ft, 7thK

This code signifies a break in the second metatarsal bone of an unidentifiable foot, where the bone fragments are no longer aligned. The fracture has failed to heal properly, indicating a nonunion, and the patient is presenting for follow-up care after initial treatment.

Apply this code when documenting subsequent encounters for a patient with a previously diagnosed displaced fracture of the second metatarsal, regardless of which foot, where imaging or clinical assessment confirms that the fracture has not united. This is appropriate for ongoing management, evaluation of nonunion, or planning for further intervention.

• Ensure documentation clearly specifies "nonunion" and that the fracture is "displaced."
• Verify that the encounter is for follow-up care after the initial treatment of the fracture.
• Do not use this code for initial encounters or for fractures that are healing normally.
