Clinical Classification Guidelines
Medical Intelligence & Overview
A fracture of the ramus of the mandible refers to a break in the vertical part of the lower jawbone, known as the mandible. The ramus is the rectangular portion that runs upward from the jaw's body and connects to the skull. When this area sustains a break, it can affect jaw function, speech, and oral health. The ICD-10 code S02.640 specifically indicates a fracture of the ramus of the mandible without specifying which side is affected, making it categorized as an unspecified side injury.
