If you have been injured in a car accident, the insurance company for the at-fault party will begin to process your claim. While they do so, it is possible that they may argue about any injury sustained in the accident was actually the result of a pre-existing medical condition. If the insurance company believes your pre-existing condition caused, or worsened, the injuries sustained in the accident, they might first demand your medical records. If you do not hand them over, and you should not do so, they might seek a subpoena to get a copy. If they find records that are similar to your current injury, there is a risk that your claim will be denied or significantly reduced.
Bear in mind that even if you sustained injuries in a car accident that are similar to ones you’ve sustained in the past, it does not mean the at-fault party can escape liability altogether. That being said, it may be possible that you’ll have to go to extraordinary measures to defend your injury. In general, if you are in a situation like this, it is highly recommended that you consult an auto accident lawyer in Memphis, TN for help and advice.
