Many people assume that a history of back problems or prior injuries will automatically lower their settlement after a car accident. If you share this concern, this post explains how these conditions are evaluated and the role they may play in your case.
The eggshell plaintiff rule in Arizona
Arizona follows a legal doctrine known as the eggshell plaintiff rule, which mandates that an at-fault driver must “take you as they find you.” This means that even if a pre-existing condition made you more prone to injury, the at-fault driver remains liable. Although not responsible for your prior health issues, they must compensate you for any worsening or aggravation of those conditions caused by the accident.
Aggravation vs. exacerbation
When reviewing your injuries, medical experts and attorneys generally draw a line between aggravation and exacerbation. An aggravation typically means that the crash caused a permanent decline in your prior condition and left you with a worse level of health than before.
An exacerbation, on the other hand, describes a short-term increase in symptoms that improves with care over time. While Arizona law allows compensation for both situations, the difference matters because a permanent aggravation supports a higher settlement than a temporary flare-up.
What to know about sharing your medical history
The main federal law protecting your medical privacy is the Health Insurance Portability and Accountability Act (HIPAA). Generally, medical providers need your written permission to share records. However, in a lawsuit, defense attorneys may still access certain records through a court order or proper subpoena, but these privacy laws still apply.
You usually do not have to sign forms giving the insurance company unrestricted access to your full medical history. In most cases, disclose only the records related to the injuries or body parts affected by the accident.
At the same time, being open with your lawyer about your medical background helps them present a clear case and protect your credibility. Insurance companies often check databases showing prior claims. Early disclosure lets your attorney distinguish prior conditions from accident-related injuries and show how the crash made them worse.
How causation impacts your claim
One of the most important aspects of a claim involving a pre-existing condition is establishing causation. This means you must prove that the crash made your condition worse, not that you are just experiencing symptoms you already had before.
Insurance companies often argue that current pain or limitations existed before the accident occurred. They may point to degenerative conditions or previous treatments as evidence that the incident is not responsible for your symptoms.
This is where your medical records from before and after the accident become important. These can show a clear timeline of how your condition changed following the crash.
