Disp fx of base of second metacarpal bone, left hand, init

This code signifies a break in the base of the second metacarpal bone (index finger) in the left hand, where the bone fragments are no longer in their normal alignment. It specifically indicates that this is the initial treatment encounter for a fracture that has not broken through the skin.

Apply this code for a patient presenting for the first time with a newly diagnosed, displaced fracture at the base of their left second metacarpal. This is appropriate for initial evaluation, imaging, and treatment planning for a closed fracture.

• Ensure documentation specifies "displaced" and "base of second metacarpal" on the left hand.
• Confirm the encounter is for the initial treatment of the fracture, not a follow-up.
• Verify the fracture is closed; if open, a different code would be required.
