Disp fx of neck of fourth MC bone, r hand, init for opn fx

This code describes a break in the neck of the fourth metacarpal bone in the right hand, where the bone fragments are no longer in their normal alignment. This specific injury is an open fracture, meaning there is a wound that communicates with the fracture site.

Use this code for initial treatment of a patient presenting with an open fracture of the right fourth metacarpal neck. This applies to scenarios such as a crush injury or direct trauma to the hand resulting in an open wound and a displaced fracture of this specific bone.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the neck of the fourth metacarpal.
• Verify laterality (right hand) is explicitly stated in the medical record.
• The "B" in the seventh character indicates an initial encounter for an open fracture; subsequent encounters will require different seventh characters.
