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

This code signifies a displaced fracture of the medial cuneiform bone in the right foot that has previously been treated but is now healing improperly, resulting in malunion. The bone fragments have united in an anatomically incorrect position, which can lead to functional impairment and pain.

Apply this code when a patient presents for follow-up care of a right medial cuneiform fracture that is documented as displaced and is currently exhibiting signs of malunion. This typically occurs after initial treatment, such as casting or surgery, and the physician notes that the bone has not healed correctly.

• Ensure documentation explicitly states "malunion" and specifies the "right medial cuneiform."
• Verify the fracture was initially "displaced" as this is a specific characteristic of the code.
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing care after the initial treatment phase.
