Disp fx of base of second metacarpal bone, left hand, 7thP

This code signifies a fracture at the base of the second metacarpal bone in the left hand that has healed improperly, resulting in a malunion. The fracture was initially displaced, and the current encounter is for ongoing treatment or evaluation of this complication.

Apply this code when a patient presents for follow-up care, physical therapy, or surgical intervention related to a previously treated, displaced fracture of the left second metacarpal base that has healed in an anatomically incorrect position. This includes scenarios where the malunion is causing functional impairment or pain.

• Ensure documentation clearly specifies "malunion" and not "nonunion" for accurate coding.
• Verify the laterality (left hand) and the specific bone (second metacarpal base) are correctly identified.
• Always sequence this code after any primary reason for the current encounter, if applicable.
