Disp fx of neck of first MC bone, left hand, init for opn fx

This code signifies a break in the neck of the first metacarpal bone (thumb) on the left hand, where the bone fragments are not properly aligned. This specific injury involves an open fracture, meaning the skin and soft tissues have been compromised, exposing the bone to the outside environment.

This code is appropriate for the initial encounter when a patient presents with a newly diagnosed, displaced open fracture of the left thumb metacarpal neck. It should be used for the primary treatment of this specific injury, such as surgical repair or initial wound management.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the left first metacarpal neck.
• Confirm this is the "initial encounter" for treatment of this specific fracture. Subsequent care would require a different encounter character.
• Always review operative reports and physician notes for details on the fracture type, location, displacement, and open vs. closed status.
