Disp fx of first metatarsal bone, r foot, init for opn fx

This diagnosis code signifies a break in the first metatarsal bone of the right foot, where the bone fragments are no longer in their normal alignment. The fracture is open, meaning there is a wound that communicates with the fracture site, and this code is specifically for the initial treatment of this injury.

Apply this code when documenting the first encounter for a patient presenting with an open, displaced fracture of the great toe's metatarsal bone on the right foot. This is appropriate for initial surgical repair, casting, or other definitive treatment for the acute injury.

• Ensure documentation clearly specifies "displaced" and "open" for accurate code assignment.
• Verify the laterality is "right foot" and the specific bone is the "first metatarsal."
• The "B" seventh character indicates an initial encounter for active treatment of the fracture.
