Disp fx of med cuneiform of r foot, subs for fx w nonunion

This code signifies a break in the medial cuneiform bone of the right foot that has shifted out of its normal alignment. It specifically indicates that the fracture has not healed properly and the patient is receiving ongoing treatment for this nonunion.

Apply this code when a patient presents for follow-up care, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed displaced fracture of the right medial cuneiform that has failed to unite. This is appropriate for encounters occurring after the initial treatment phase, where nonunion is the primary concern.

• Ensure documentation clearly states "nonunion" and specifies the "right" foot and "medial cuneiform."
• Verify the fracture is explicitly described as "displaced" in the medical record.
• This code is for subsequent encounters; use an initial encounter code for the first presentation of the fracture.
