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

This code signifies a break in the base of the fourth metacarpal bone in the left hand, where the bone fragments are no longer in their normal alignment. This type of fracture is typically caused by direct trauma or an axial load to the hand.

Apply this code for a patient presenting with a newly diagnosed, non-aligned fracture of the base of the left fourth metacarpal. This is appropriate for the initial visit where the fracture is being evaluated and treatment plans are being established, and the skin over the fracture site remains intact.

• Ensure documentation specifies "displaced" and "closed" for accurate code assignment.
• Verify the laterality (left hand) and the specific metacarpal (fourth) are clearly documented.
• The "A" suffix indicates an initial encounter for active treatment of the fracture.
