You were stopped at a light on Sahara, someone slammed into the back of your car, and now your neck and lower back won’t quit. Then the adjuster calls and says your pain was “pre-existing” — as if the crash had nothing to do with it.
Here’s the short version: a pre-existing injury after a rear-end crash does not end your claim in Nevada. The at-fault driver is still responsible for making your condition worse. Below is what the “pre-existing” argument really means, how insurers build it, and what actually protects you — written for someone who did everything right and is now being treated like they made it up.
Why the insurance company is calling your injury “pre-existing”
It feels personal, but it isn’t. It’s a script. When an adjuster labels your injury “pre-existing,” they’re doing one thing: trying to cut what they owe by arguing the crash didn’t cause your pain — your history did.
They lean on this hard in rear-end and low-speed cases, where the property damage looks minor and they’re betting a jury will doubt that a “little” hit could hurt you. If you’ve ever had neck pain, a sore back, arthritis, or an old sports or work injury, they’ll point at it and say, see, this was already there.
That’s an argument, not a ruling. And in Nevada, it runs into a rule that exists specifically to stop it.
A pre-existing condition doesn’t end your claim in Nevada
Nevada follows what’s known as the eggshell plaintiff rule: the person who caused the crash takes you as they find you. If you were more vulnerable to injury because of an existing condition, that’s their problem, not a discount. They don’t get to injure someone with a bad back and then argue they should pay less because the back was bad.
So having a prior injury does not bar you from recovering. What the at-fault driver is responsible for is the worsening — the way the rear-end collision made your condition worse than it was the day before the crash. That’s the honest line, and it matters: you’re not claiming the insurer owes you for an old injury in its old state. You’re claiming they owe you for the change their driver caused. Nevada law lets you pursue exactly that, and it’s the backbone of most rear-end accident claims where the injured person had any prior history at all — which is most adults.
What “aggravation of a pre-existing condition” really means
“Aggravation” is the legal word for made worse. A stable, quiet condition that the crash turned into a painful, limiting, treatment-heavy one is a compensable injury in Nevada.
The practical test the insurer, and eventually a jury, looks at: did the crash cause a real, measurable change? More pain, new symptoms, new treatment you didn’t need before, a drop in what you can do at work or at home. A herniated disc that was managed and silent for years can absolutely become a surgical problem after a rear-end hit — and that shift is the injury. The same logic drives how a rear-end crash affects your spine long-term: the damage isn’t always obvious on day one, and it isn’t erased by the fact that your body wasn’t perfect beforehand.
How insurers build the “pre-existing” argument
Knowing the playbook takes the sting out of it. Adjusters build the pre-existing defense a few predictable ways:
- Fishing through your medical records. They’ll ask you to sign a medical authorization, then pull years of history looking for any mention of neck, back, or joint pain to wave around.
- Weaponizing the word “degenerative.” If your MRI says “degenerative disc disease,” they’ll frame it as proof you were falling apart anyway. But nearly every adult over 30 has some degeneration, and most have zero symptoms. Degeneration on a scan is not the same as pain and disability before the crash — a distinction that comes up constantly in rear-end disk herniation claims.
- Punishing gaps in treatment. If you waited to see a doctor or stopped going, they’ll argue you must not have been hurt.
- Watching your social media. One photo of you at a barbecue becomes “look how fine they are.”
None of this proves your case is weak. It just tells you where they’ll push.
What actually proves the rear-end crash made your injury worse
The pre-existing argument dies in the face of good documentation. What carries the most weight:
Before-and-after records. The single strongest piece of evidence is a clear picture of your condition before the crash next to your condition after. If you were stable, working, and not treating — then suddenly you’re in physical therapy and can’t lift your kid — that contrast does the talking.
Consistent treatment. Seeing your doctors, following through, and giving your symptoms a paper trail. Consistency is credibility.
New or worsened imaging. Fresh MRIs, CT scans, or X-rays that show new damage, or old damage that’s clearly progressed.
Your doctor’s causation opinion. A treating physician who can explain, in plain terms, how the collision worsened your condition is often what turns an adjuster’s “pre-existing” into a settlement. Locking in medical evidence early is a big part of the steps that matter right after being rear-ended.
Mistakes that hand the insurer its argument
A few avoidable moves make the pre-existing defense easy for them:
- Signing a blanket medical authorization. You generally don’t have to give an insurer unlimited access to your entire medical history. A broad release is how they go fishing. This is worth a lawyer’s eyes before you sign anything.
- Hiding or downplaying the old injury. Don’t. If they find it later — and they will — it looks like you lied, and it damages everything you say. Honesty plus documentation beats concealment every time.
- Gapping out of treatment. Every unexplained gap becomes their exhibit.
- Giving a recorded statement without advice. Casual answers get twisted into admissions.
Frequently Asked Questions
Can the insurance company get all my old medical records?
Not automatically, and not without limits. Insurers often ask you to sign a medical authorization, then comb through years of history looking for anything to call “pre-existing.” You generally don’t have to hand over unlimited access to your entire medical past. Records relevant to the body parts you injured may be fair game, but a blanket release is usually broader than they’re entitled to — and courts can limit overly broad requests to what’s actually related to your claim. Before you sign anything an adjuster sends, have a Las Vegas car accident lawyer review it. Controlling what they can pull is one of the simplest ways to keep the pre-existing argument from spiraling.
What if my MRI says “degenerative disc disease”?
That phrase alarms people, but it’s common and often meaningless on its own. Most adults over 30 show some disc degeneration on imaging, and the large majority have no symptoms from it. Degeneration on a scan is not proof you were in pain before your crash. What matters is whether you were functioning fine beforehand and then declined afterward. A rear-end collision can turn a quiet, degenerated disc into a painful, herniated, treatment-heavy problem — and that change is a real injury. A treating doctor can explain the difference between age-related findings and crash-related aggravation, which is exactly what defeats the “you were already falling apart” argument.
Do I have to give the adjuster a recorded statement?
Not to the other driver’s insurance company. In a typical Nevada claim, you’re under no legal obligation to give a recorded statement to the at-fault driver’s insurer — they aren’t your insurer and have no right to interview you. Adjusters call early, often within a day or two, and ask questions built to lock you into answers they later twist into “you weren’t really hurt” or “it was pre-existing.” It’s reasonable to decline until you’ve spoken with a lawyer. Your own insurer is different — your policy usually requires you to cooperate — but even then, the wording matters, and you can have an attorney handle it. When a pre-existing argument is already in play, one loose sentence can do real damage.
Can the insurance company make me see their doctor?
Not just by asking — at least not before a lawsuit is filed. The at-fault driver’s insurer can’t force you to see a doctor of its choosing during the normal claims process. If your case goes into litigation, the defense can ask the court to order a medical examination — often called an “independent” or defense medical exam — but that’s a formal step with rules around it, not something an adjuster can demand over the phone. Separately, your own policy may require an exam if you’re pursuing uninsured or underinsured motorist benefits. If an insurer is pressuring you to be examined by their doctor, that’s a good moment to talk to a Las Vegas attorney before agreeing to anything.
How long do I have to file a rear-end injury claim in Nevada?
For most Nevada personal injury cases, you have two years from the date of the crash to file a lawsuit. Talking to the insurance company does not extend that deadline, and once it passes, a court can dismiss your case no matter how strong it is. Some situations shift the start date, such as an injury that isn’t discovered right away, so it’s smart to confirm your exact deadline early rather than assume. Waiting also weakens the medical timeline that beats a pre-existing defense, so acting sooner protects both your rights and your evidence.
Does a pre-existing injury lower what your claim is worth?
Sometimes it complicates the math, but it doesn’t erase the claim. Because you’re being compensated for the aggravation, the value turns on how clearly you can separate your baseline from the harm the crash added. The stronger that line, the stronger the number.
How much a specific case is worth depends on your injuries, treatment, lost income, and how well the change is documented — there’s no honest one-size figure. If you want to understand the drivers behind what a rear-end claim is worth in more detail, that’s covered separately. The point here is simpler: a prior injury is a reason to document carefully, not a reason to walk away.
Talk to a Las Vegas attorney before the insurer locks in its story
If an adjuster is already telling you your injury was “pre-existing,” they’ve started building their file. This is the moment to even the sides.
Howard Injury Law was founded by attorney Glen Howard, who spent years as an insurance defense attorney — the person who used to build these exact “pre-existing” arguments for the other side. He knows how they read your records, where they overreach, and how to answer it with the before-and-after evidence that makes the argument fall apart. That’s a real advantage when the whole dispute is about credibility.
A few things worth knowing:
- The first consultation is free, and there’s no obligation.
- Our fee is contingency — no fee unless we win your case.
- In Nevada, you generally have two years from the date of the crash to file a personal injury lawsuit. Negotiating with an insurer does not pause that clock, and waiting only helps their “you weren’t really hurt” narrative. (Every case has its own facts, so confirm your specific deadline early.)
If you’re not sure whether you even have a case because of your history, that’s exactly the question to bring us.

Frequently Asked Questions
Can I still file a claim if I had a prior back or neck injury?
Yes. A prior back or neck injury does not disqualify you in Nevada. Under the eggshell plaintiff rule, the at-fault driver is responsible for the harm the crash caused, including making an existing condition worse. What you’re recovering for is the aggravation — the new pain, new treatment, and new limitations that came from the collision. Most adults have some prior wear and tear, and insurers know it, which is why they raise it so often. The key is documenting the difference between how you were before the crash and how you are after. If that contrast is clear, a prior injury is a detail to prove around, not a dead end.
Can the insurance company get all my old medical records?
Not automatically, and not without limits. Insurers often ask you to sign a broad medical authorization so they can comb through years of history looking for anything to call “pre-existing.” You generally don’t have to hand over unlimited access to your entire medical past.

Should I tell my doctor about my old injury?
Yes — always be honest with your treating doctors. Hiding a prior injury backfires: insurers usually find it, and once they catch an omission, it undermines your credibility on everything. Full disclosure actually helps you, because it lets your doctor document the difference between your old baseline and your current condition, which is exactly the evidence that proves aggravation. Honesty plus a clear before-and-after record is far stronger than a clean-sounding story that falls apart under scrutiny. Tell your doctor the truth, and let the documentation do the work.
