Final answer:
Coma is not included in each and every codable head injury.
Step-by-step explanation:
Coma is not included in each and every codable head injury. A head injury can result in various symptoms depending on the severity and location of the injury. Coma is a state of unconsciousness where the person is unresponsive to external stimuli and cannot be awakened. While some severe head injuries may lead to coma, not all head injuries result in this condition. It is important to assess and evaluate each individual case to determine the specific effects and symptoms of a head injury.
