When an insurance adjuster finds out you have a prior injury or chronic condition, the response is almost predictable. They will argue that your current pain is not from the accident at all. That your back was already bad. That your knee was already damaged. It is one of the most common tactics used to reduce or deny a personal injury claim, and it catches a lot of people off guard.
The reality is that a pre-existing condition does not automatically disqualify you from recovering compensation. What matters is whether the accident made things worse.
What Wisconsin Law Actually Says
Wisconsin follows the eggshell plaintiff rule, a long-established legal principle that holds a defendant responsible for the full extent of harm caused to an injured person, even if that person was more vulnerable to injury than the average individual. In plain terms, the at-fault party takes the victim as they find them.
If someone with a history of back problems is rear-ended and their condition is significantly aggravated, the responsible driver cannot escape liability simply because the victim was already dealing with pain. The aggravation itself is compensable.
That said, there is an important distinction between two different situations:
- Aggravation of a pre-existing condition: The accident made an existing problem materially worse, which is compensable
- Unrelated pre-existing condition: The accident had no effect on the prior condition, which generally is not part of the claim
The line between these two situations is where most disputes actually happen, and documentation is what decides the outcome.
Why Documentation Matters More With a Prior Condition
Insurance companies will request your full medical history when a pre-existing condition is involved. They are looking for anything they can use to argue that your current symptoms existed before the accident. This makes the quality of your medical records before and after the incident especially significant.
A few things that can support your claim:
- Medical records showing the condition was stable or managed prior to the accident
- Treatment notes from after the accident documenting a clear change in symptoms
- Imaging studies comparing your condition before and after
- Statements from treating physicians describing the impact of the accident on your prior condition
Getting consistent medical treatment after an accident is not just about your health. It creates a documented record that shows exactly when your condition changed and why.
What Happens When Both Sides Dispute the Medical Evidence
This is where these cases get complicated. Defense attorneys and insurance companies sometimes hire their own medical examiners to review your records and offer opinions that minimize the accident’s impact. These independent medical examinations, often called IMEs, are not always as neutral as the name suggests.
A Kenosha personal injury lawyer can help you prepare for this process, identify weaknesses in opposing medical opinions, and gather the right evidence to counter arguments that your injuries were purely pre-existing.
What You Should Avoid Doing
If you have a prior injury or health condition and you have been hurt in an accident, a few missteps can seriously undermine your claim:
- Downplaying prior conditions when speaking with doctors or adjusters
- Waiting too long to seek medical treatment after the accident
- Giving a recorded statement to the insurance company without legal guidance
- Assuming your prior condition means you have no case
Transparency with your attorney and your medical providers is always the right approach. Trying to hide prior conditions tends to backfire and gives the defense more ammunition, not less.
Getting the Right Help Early
Pre-existing condition cases require a clear theory of how the accident changed your health, supported by medical evidence that connects the two. Without that foundation, even a legitimate claim can fall apart under pressure from an insurer.
