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

This code signifies a break in the third metatarsal bone of the foot that is not in its normal anatomical alignment. The fracture has broken through the skin, creating an open wound, and this encounter represents the initial treatment for the injury. The specific foot (left or right) is not documented.

Apply this code when a patient presents for the first time with a traumatic injury resulting in a visibly open fracture of the third metatarsal. This is appropriate for initial surgical repair, wound debridement, or other primary management of the open fracture. It should be used when the laterality of the foot is not specified in the medical record.

• Always assign an additional code for the open wound classification (e.g., Gustilo-Anderson classification) if documented.
• Ensure the documentation clearly states "displaced" and "open fracture" for accurate code assignment.
• Do not use this code for subsequent encounters or for closed fractures.
