Disp fx of neck of second MC bone, l hand, init for opn fx

This code signifies a break in the neck 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 are compromised, exposing the bone to the external environment. This is the initial encounter for the treatment of this specific injury.

This code is appropriate for a patient presenting for the first time with an open fracture of the neck of their left second metacarpal. This includes situations where the bone has pierced the skin or there is a wound communicating with the fracture site. It should be used for the acute treatment phase, such as emergency department visits or initial surgical repair.

• Ensure documentation clearly specifies "open fracture" and "displaced" for the neck of the second metacarpal.
• Verify laterality (left hand) is explicitly stated in the medical record.
• The "B" seventh character indicates an initial encounter for an open fracture; use subsequent characters for follow-up care.
