Had a Bad Back Before Your New Braunfels Crash? It Still Counts

Texas law says a defendant takes you as they find you, but insurers still use old injuries to shrink claims. Here's how that actually plays out.

If you had a bad knee, an old back injury, or arthritis before a wreck near New Braunfels, you might assume the insurance company can just point at your medical history and walk away. That's not how the law works. Texas follows what's often called the eggshell plaintiff rule, which means a person who causes a crash is responsible for the harm they actually cause, even if that harm is worse than it would have been for someone in perfect health.

In plain terms: if a low-speed fender bender shatters your hip because you already had thin bone density, the at-fault driver doesn't get a discount just because you were more fragile than average. But insurance adjusters know most people have never heard of this rule, and they use preexisting conditions as a favorite reason to lowball or deny claims. Understanding how this actually works helps you push back with facts instead of guesswork.

What the Eggshell Plaintiff Rule Really Says

The idea comes from an old legal principle: a wrongdoer takes their victim as they find them. If you're unusually vulnerable to injury, that vulnerability doesn't reduce the responsibility of the person who caused the crash. The law doesn't require you to have been in perfect health before you got hurt.

This matters because almost everyone has some kind of medical history by the time they're old enough to drive. Old sports injuries, arthritis, prior surgeries, degenerative disc changes that show up on imaging whether or not they ever caused pain. None of that automatically disqualifies you from recovering for a new crash-related injury.

Why Insurers Zero In on Your Medical Records

Insurance companies request years of medical records for a reason. They're not just checking for fraud. They're looking for anything they can point to and say, 'this problem existed before the wreck, so we don't owe for it.'

This is a business strategy, not a neutral fact-finding mission. An adjuster's job includes minimizing what the company pays out. Finding a preexisting condition, even an unrelated one, gives them a talking point to use in negotiations, and many people accept a lower offer simply because they don't know how to respond to it.

Aggravation of an Old Injury Is Still a Real Injury

There's an important legal distinction between a condition that already existed and a condition that got worse because of the crash. If a wreck aggravates an old back problem that had been stable or mild, the worsening itself is usually a compensable injury, even though the underlying condition came first.

The tricky part is proving the difference between 'this was already happening' and 'this got worse because of the wreck.' That's where medical evidence becomes central. Doctors compare your condition and function before and after the crash to show a change, not just a diagnosis that happens to be on your chart.

How to Protect a Claim With a Preexisting Condition

Be upfront with every doctor you see after the crash about what hurt before and what's different now. Trying to hide an old injury almost always backfires once records surface, and it can make an adjuster question your credibility on everything else in the claim.

Ask your treating doctor to document your baseline. A note describing how your old injury was functioning before the crash, and how it changed afterward, is far more useful than records alone. Consistent, honest follow-up care also creates a clear timeline that's harder to dismiss as unrelated.

Don't sign broad medical authorization forms for the insurance company without understanding what records they'll pull. A general authorization can let an adjuster dig through your entire medical history looking for ammunition, not just records related to the crash.

What This Looks Like in Real Negotiations

In practice, preexisting condition arguments usually show up as a flat reduction offer: the adjuster suggests a portion of your treatment was 'probably' related to your old condition, not the crash, and offers less because of it. That's a negotiating position, not a medical fact, and it's often based on a records review rather than an actual exam of you.

Countering it usually means having your doctor speak clearly to causation, aggravation, and the change in your condition. General information like this can help you understand the landscape, but it's not a substitute for someone reviewing your specific records and history.
