If you had a medical condition before your car accident, you may be worried that the insurance company will use it to deny or reduce your claim. It is true that pre-existing conditions are one of the most common tools insurance adjusters use to minimize settlement values. However, Pennsylvania law provides strong protections for accident victims with prior health issues through a legal doctrine known as the eggshell plaintiff rule.
Understanding how this doctrine works, what tactics insurance companies use, and how to protect your claim when pre-existing conditions are involved is essential for ensuring you receive fair compensation.
The Eggshell Plaintiff Doctrine
The eggshell plaintiff rule, also known as the thin skull rule, is a long-established legal principle that holds a defendant liable for the full extent of the plaintiff’s injuries, even if those injuries are more severe than would be expected in a typical person. The name comes from the metaphor of a plaintiff whose skull is as thin as an eggshell. If a defendant’s negligence causes the plaintiff’s skull to fracture when a normal skull would not, the defendant is still fully liable for the injury.
In the context of car accidents, this means that if the accident aggravated, accelerated, or activated a pre-existing condition, the at-fault driver is responsible for the full extent of the worsened condition. The defendant takes the plaintiff as they find them, prior health issues and all.
Aggravation vs. Causation
The key legal distinction in pre-existing condition cases is between aggravation and causation. If the accident caused a completely new injury, the defendant is liable for the full injury. If the accident aggravated or worsened a pre-existing condition, the defendant is liable for the aggravation, meaning the difference between the plaintiff’s condition before the accident and their condition after.
For example, if you had a degenerative disc condition that was managed and not causing pain before the accident, but the collision caused a herniation that now requires surgery, the at-fault driver is responsible for the surgical costs and the associated pain and suffering. The fact that your spine was already compromised does not reduce the defendant’s responsibility. Attorneys helping accident victims in the Bethlehem area regularly handle cases where pre-existing conditions are central to the claim.
Insurance Company Tactics With Pre-Existing Conditions
Insurance companies use pre-existing conditions as a primary strategy for reducing claim values. Common tactics include arguing that the plaintiff’s symptoms are entirely caused by the pre-existing condition rather than the accident, claiming that any treatment after the accident is continuation of prior care rather than new care necessitated by the crash, obtaining the plaintiff’s complete medical history going back years or decades to find prior complaints of similar symptoms, and using independent medical examiners who are known to attribute injuries to pre-existing conditions rather than accident-related causes.
Medical Evidence Is Critical
The strength of a pre-existing condition case depends heavily on the medical evidence. Your treating physicians must clearly document the difference between your condition before and after the accident. Records showing that you were asymptomatic or stable before the crash and symptomatic or deteriorating after it provide compelling evidence that the accident caused the change.
Diagnostic imaging is particularly valuable. If you had an MRI or X-ray before the accident showing a stable condition, and post-accident imaging shows a new herniation, fracture, or other change, the comparison provides objective proof of aggravation.
Disclosing Pre-Existing Conditions
One of the worst mistakes you can make in a pre-existing condition case is failing to disclose your medical history. Insurance companies and defense attorneys will obtain your prior medical records, and if you have been less than forthcoming about your health history, your credibility will be severely damaged.
The better approach is full transparency. Acknowledge the pre-existing condition and focus on demonstrating how the accident made it worse. An honest, well-documented case is far more persuasive than one that appears to hide relevant medical history.
Protecting Your Claim
If you have pre-existing conditions and are pursuing a car accident claim in Pennsylvania, seek medical attention immediately after the accident and describe all your symptoms thoroughly to your doctor. Follow your treatment plan without interruption. Request copies of both your pre-accident and post-accident medical records. Keep a daily journal documenting how your symptoms have changed since the accident.
The eggshell plaintiff doctrine is a powerful protection, but it requires a well-built case supported by strong medical evidence. With the right documentation and approach, a pre-existing condition does not have to prevent you from recovering full compensation for the harm the accident caused.
