Any person who has been involved in a car accident where injury may have occurred should seek medical attention to rule out injury or have any injuries they've suffered, documented and treated. An auto insurance provider will not pay out for any physical injuries without a car accident medical assessment. This is because all injuries must be documented. A car accident medical assessment will allow a medical professional to document, and show, that injuries were indeed sustained, and it will show the extent of said injuries. Refusing medical assessment and or treatment is never recommended. If you have been involved in a car accident in which there is a potential that you have suffered any type of injury, and you do not seek a medical assessment you may be denied compensation.
