S02.650 Fracture of angle of mandible, unspecified side

ICD-10-CM S02.650: Fracture of angle of mandible, unspecified side

ICD-10-CM code S02.650 designates a fracture of the angle of the mandible on an unspecified side, classified under the Injury or Poisoning semantic type. The code is an active terminology concept with a parent category of S02.65. Clinical literature notes that mandibular angle fractures can involve complications like infection or nonunion, and may follow dental procedures. 1 2 3

Plain-language overview

ICD-10-CM code S02.650 identifies a fracture located at the angle of the mandible without specifying whether the injury occurred on the left or right side. 1

What this code represents

The terminology record for S02.650 assigns a semantic type of Injury or Poisoning, establishing this concept within the ICD-10-CM version 2026 system. 1 3

Code S02.650 is an active concept that has no narrower child concepts within the terminology system, meaning it does not branch into more specific subcodes. 1

Coding details

In the ICD-10-CM hierarchy, S02.650 rolls up to the parent concept S02.65, which is the broader category for a fracture of the angle of the mandible within the terminology. 1

Clinical context

Clinical literature documents that a fracture through the mandibular angle can occur as a subsequent complication following the extraction of a lower third molar tooth. 2

Medical case records indicate that injuries to the mandibular angle can present with clinical signs including localized redness, swelling, and the formation of an abscess in the affected region. 2

Documentation considerations

The official display label for S02.650 explicitly states an unspecified side, directly reflecting that laterality for the mandibular angle fracture is not identified in the code's terminology. 1

What the sources add

While the terminology record defines the code structure and injury classification, the clinical article adds operational context by describing real-world complications and anatomical presentations of mandibular angle fractures. 1 2
