Disp fx of shaft of 2nd MC bone, l hand, 7thP

This code signifies a left-sided fracture involving the shaft of the second metacarpal bone that has healed improperly. "Malunion" indicates that the bone fragments have joined in a deformed or misaligned position, which can lead to functional impairment. This specific code is used when the patient is receiving follow-up care for this previously treated, but now malunited, fracture.

Apply this code when a patient presents for ongoing management, evaluation, or treatment of a malunited fracture of the shaft of their left second metacarpal. This includes visits for assessing the extent of malunion, planning corrective surgery, or managing complications arising from the malunion. It is appropriate for any encounter after the initial treatment phase where the malunion is the focus.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the laterality (left hand) and the specific bone (second metacarpal shaft).
• Do not use for initial fracture treatment or for nonunion (failure to heal).
