Disp fx of shaft of third MC bone, l hand, init for opn fx

This code signifies a break in the middle section (shaft) of the third 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 tissues surrounding the fracture site have been compromised, exposing the bone.

This code is appropriate for the initial treatment of a patient presenting with an open fracture of the shaft of the left third metacarpal. This includes scenarios such as a crush injury or a direct impact causing the bone to protrude through the skin. It is used for the first encounter where definitive treatment, such as surgical debridement and fixation, is planned or performed.

• Ensure documentation clearly specifies "open fracture" and the specific metacarpal (third) and laterality (left).
• Confirm this is the initial encounter for the open fracture; subsequent encounters will require different seventh characters.
• Always sequence this code with an external cause code to describe the circumstances of the injury.
