Disp fx of base of second metacarpal bone, left hand, 7thB

This code signifies a break at the bottom portion of the second metacarpal bone in the left hand, where the bone fragments are no longer in their normal alignment. It specifically indicates that the skin and soft tissue overlying the fracture site have been compromised, exposing the bone to the outside environment.

Apply this code for a patient presenting with an open fracture of the base of their left second metacarpal, such as from a crush injury or direct trauma. This code is appropriate for the initial treatment encounter for this specific injury.

• Ensure documentation clearly specifies "left hand" and "second metacarpal base" for accurate coding.
• Confirm the fracture is explicitly documented as "open" and "displaced."
• Verify this is the patient's first encounter for this particular fracture to use the "B" seventh character.
