A Car Accident Aggravated My Pre-Existing Condition—What Does This Mean for My Settlement?
A car accident aggravated pre-existing condition settlement is available under Tennessee law, but only for the part of your condition that actually got worse, not the condition itself. Insurance companies routinely argue that your pain comes from an old injury rather than the crash, so working with a car accident lawyer in Smyrna, TN early can help pin down which symptoms trace back to the wreck.

Can you get compensation if a car accident aggravates a pre-existing condition?
Yes. A crash doesn’t have to create a brand-new injury for you to have a valid claim. If you had a bad back, an old knee injury, or a spine that already gave you trouble, and the wreck made it worse, Tennessee law lets you recover for that worsening. What you can’t recover for is the condition as it existed before the crash; the law draws a line between the old injury and the new harm the crash caused.
Aggravating a pre-existing condition doesn’t erase your claim; it changes what you’re allowed to recover for. Medical expenses tied to the flare-up and lost wages while you’re recovering are both fair game. So is the pain and suffering caused by the aggravation itself. The care you were already getting for the old condition before the accident generally isn’t.
What is the eggshell plaintiff rule?
Under Tennessee’s eggshell plaintiff rule, the person who caused your crash has to take you as they found you, not as a hypothetically healthy driver. If the crash left you worse off than someone without your medical history would have been, the at-fault driver is still responsible for that difference. Tennessee courts don’t reduce what you’re owed just because you were more vulnerable to injury than average.
There’s an exception that works in your favor. If your pre-existing condition was silent before the crash, meaning it wasn’t causing you pain or limiting you day to day, Tennessee law can hold the at-fault driver responsible for the full extent of the harm that surfaced afterward, not just the increment.
Why do insurance companies push back on pre-existing conditions?
Car accidents that aggravate a pre-existing condition can turn into claims that are tough to negotiate, because insurance adjusters know the rule cuts both ways. They only owe you for what the crash changed, so they look hard for evidence that nothing changed. If your medical records show the same complaints before the accident that you’re reporting after it, an adjuster will argue the crash didn’t cause any new harm at all.
That’s why your medical history becomes part of the conversation whether you like it or not. An adjuster who can point to a note from three years ago describing the same back pain has a real argument. A well-documented medical record showing a distinct change after the crash is what takes that argument away.
How do you prove a car accident made your condition worse?
Detailed medical records are the core of any claim involving pre-existing injuries or conditions. They let your personal injury lawyer draw a direct line between the crash and your worsened symptoms, showing what changed before and after.
A gap in treatment before the crash doesn’t disqualify your claim, but it puts more weight on what happens next. See a doctor as soon as symptoms flare up so there’s a clear point where things changed, and describe your symptoms the same way to every provider you see afterward. Adjusters look for inconsistencies between your ER visit and your follow-up appointments; a symptom that shows up in one record but not another becomes an argument that it isn’t related to the crash.
Statements from your treating doctors carry weight too. A physician willing to say, in their own words, that the crash caused a measurable change in your condition gives your personal injury attorneys something concrete to work with in your injury case, rather than just your account of how you feel.
How is a settlement calculated for an aggravated injury?
Under Tennessee personal injury law, a settlement in this kind of case is built around the difference the crash made, not your condition as a whole.
Let’s say you had an old disc bulge that caused occasional stiffness, but nothing you’d call real pain, and the crash left you with radiating pain and months of physical therapy. Your settlement would reflect the cost of that new treatment, the income you lost while recovering, and the pain and suffering tied to the flare-up itself, not the disc bulge you already had before anyone hit you.
Other losses tied directly to the crash, like transportation to appointments or the cost of help around the house while you recover, get factored in too. If you’re entitled to compensation for the aggravation and the insurance company won’t offer a fair number based on the medical evidence you’ve provided, your case can still go to a judge or jury for a fair result.
Is there a deadline to file if a car accident aggravated a pre-existing condition?
Yes, and this deadline can creep up quickly. Tennessee generally gives you one year from the date of the crash to file a lawsuit, and that clock runs whether or not you’ve finished treating your aggravated condition. If a government-owned vehicle, like a city or county car, was involved, the deadline to sue that government entity is shorter still, and separate notice requirements can apply. If the injured person is a minor, Tennessee law pauses the clock until they turn eighteen.
Since these claims often take time to fully document, and medical records showing the progression of your symptoms don’t always arrive quickly, it’s worth talking to a car accident lawyer about your deadline well before you assume you still have time. And if the insurance company won’t settle, remember that litigation can take considerably longer to resolve than a straightforward claim, so raising the pre-existing condition issue early gives your case more room to develop before the deadline arrives.
