Disp fx of shaft of fourth metacarpal bone, left hand, init

This diagnosis code signifies a break in the middle portion (shaft) of the fourth metacarpal bone in the left hand, where the bone fragments are no longer in their normal anatomical alignment. This is an acute injury, and the skin over the fracture site remains intact (closed fracture).

Apply this code for patients presenting with a newly diagnosed, non-aligned fracture of the shaft of their left fourth metacarpal. This is appropriate for the initial treatment or evaluation of the injury, such as in an emergency department or initial orthopedic consultation.

• Ensure documentation specifies "left hand" and "fourth metacarpal" to support this code.
• Confirm the fracture is explicitly described as "displaced" and "closed."
• The "A" suffix indicates an initial encounter for this specific fracture. Subsequent care would use a different seventh character.
