Disp fx of shaft of oth metacarpal bone, init for clos fx

This code signifies a break in the long, central part (shaft) of any metacarpal bone other than the thumb, where the bone fragments are no longer in their normal alignment. This specific diagnosis indicates the initial treatment phase for a fracture that has not broken through the skin.

Apply this code for patients presenting with a newly diagnosed, non-open fracture of the shaft of the second, third, fourth, or fifth metacarpal, where imaging confirms displacement of the bone fragments. This is appropriate for the initial evaluation and management of such an injury.

• Ensure documentation specifies "displaced" and "shaft" for metacarpals II-V.
• Confirm the encounter is for the initial treatment of the fracture.
• Distinguish from non-displaced fractures or fractures of the metacarpal head or base.
