Disp fx of third metatarsal bone, left foot, init for opn fx

This code signifies a break in the third metatarsal bone of the left foot, where the bone fragments are no longer in their normal anatomical alignment. It specifically indicates that the fracture has broken through the skin, creating an open wound, and this is the initial treatment encounter for the injury.

Apply this code for a patient presenting with a newly diagnosed open fracture of the left third metatarsal requiring initial treatment. This includes scenarios such as emergency department visits, initial surgical repair, or the first clinic visit for management of the acute injury.

• Always confirm laterality (left vs. right) and the specific metatarsal bone involved.
• Ensure documentation clearly states "open fracture" and that this is the "initial encounter" for treatment.
• An additional code for the open wound (e.g., from the T81.3- series for wound dehiscence or infection) may be necessary if complications arise, but not for the initial open wound itself.
