Don’t panic if the insurance adjuster says a TBI was pre-existing. You could still be entitled to financial compensation for aggravation of a pre-existing condition if the accident caused new symptoms or made an existing condition worse. Follow these steps to protect your rights.Do Not Accept the Adjuster\u2019s Claim as FinalInsurance companies are not courts. Their decisions are not binding. It\u2019s better to think of a denial as the opening of negotiations rather than the last word. Without legal representation, the insurer has the upper hand in a traumatic brain injury insurance dispute.Before we go any further, it\u2019s important that you understand the somewhat oddly named eggshell plaintiff rule. This legal doctrine takes its name from a hypothetical: imagine someone has an unusually thin skull and is hurt in an accident that someone else caused. The injuries they sustain are worse than those that a person with a normal skull would have suffered under the same circumstances.The eggshell skull rule holds that the person who caused the accident is fully responsible for that person\u2019s injuries, regardless of whether they knew about the injured person\u2019s underlying condition and that the plaintiff is unusually susceptible to injury. Most states \u2013 including Oklahoma \u2013 follow the eggshell skull doctrine.What this means for you is that the person who worsened your TBI (and, by extension, their insurer) is responsible for your injuries, even if someone without a pre-existing condition wouldn\u2019t have been hurt as badly as you were. The insurance company knows about this rule and hopes that you don\u2019t.Get Medical Care and Explain Any New or Worsened SymptomsPerhaps the most important thing you can do to support your pre-existing condition TBI claim is to get medical evidence of your changing condition to show the accident worsened it. Seek medical treatment if you have not already. Your primary care physician can recommend you to a specialist. Be sure to tell them about the accident, your past medical history, and any new symptoms you\u2019ve developed. They will run diagnostic tests to determine the extent of your injuries and how the accident aggravated them. Keep your medical records organized.Gather Records That Show the Difference Before and After the AccidentAnother way to support your claim is to get testimony from people who knew you before the accident and can speak to how your symptoms have gotten worse afterward. Collect any other documentation that helps prove this, such as pay records showing that you’re no longer able to work.Avoid Signing a Release or Accepting a Quick SettlementAt some point, the insurance company might \u201cgive in\u201d and make you a settlement offer. It might even suggest that this is a one-time-only, take-it-or-leave-it deal. Don\u2019t believe them, and don\u2019t sign anything yet. Once you do, you release the insurance company from further liability, meaning you can\u2019t go back for more compensation later. Instead, get legal help right away.Contact an Oklahoma City Traumatic Brain Injury Lawyer TodayPerhaps the single most important thing you can do to protect your rights is to hire an Oklahoma City traumatic brain injury lawyer.
