Disp fx of shaft of first metacarpal bone, left hand, init

This diagnosis code indicates a break in the long, central part of the first metacarpal bone (thumb) in the left hand. The bone fragments are not properly aligned, meaning they are shifted from their normal position. This code is used for the initial treatment of this type of fracture when the skin remains intact over the injury.

Apply this code when documenting the initial encounter for a patient presenting with a displaced fracture of the shaft of their left first metacarpal. This includes scenarios such as emergency department visits, initial orthopedic consultations, or primary care visits where the fracture is first diagnosed and treatment planning begins. It is specifically for closed fractures where there is no open wound communicating with the fracture site.

• Ensure documentation specifies "displaced" and "shaft" to differentiate from non-displaced or other fracture locations.
• Verify the laterality is "left hand" and not right or unspecified.
• The "A" seventh character signifies an initial encounter for active treatment of the fracture.
