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

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

This code is appropriate for the initial treatment of a patient presenting with a displaced open fracture of the neck of the fourth metacarpal in the left hand. This includes scenarios such as a crush injury or direct trauma resulting in an open wound and a visibly misaligned fracture. It is used for the first encounter where definitive treatment for the fracture is provided.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the fourth metacarpal of the left hand.
• Verify this is the initial encounter for the open fracture; subsequent encounters will require a different seventh character.
• Always code the open fracture type (e.g., Gustilo-Anderson classification) if documented, in addition to the fracture code.
