Disp fx of med cuneiform of unsp ft, subs for fx w nonunion

This code signifies a break in the medial cuneiform bone, located in the midfoot, where the bone fragments are no longer in their normal alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone is failing to heal properly after a typical healing period.

This code is appropriate for documenting ongoing treatment for a medial cuneiform fracture that has not united. This includes situations where a patient is undergoing further evaluation, conservative management, or surgical intervention specifically addressing the nonunion of the fracture. It would be used after the initial treatment phase has concluded.

• Ensure documentation clearly states "nonunion" and specifies the medial cuneiform.
• Verify the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the laterality (unspecified foot) aligns with the clinical record.
