The Insurance Company Says My Injury Was Pre-Existing: Can I Still Win My Case?
Few things are more frustrating than recovering from a car accident on Route 45 or a slip and fall on Convent Street, only to receive a denial letter from an insurance adjuster. The reason? They claim your pain isn’t from the crash, but from a “pre-existing condition.” This is a standard tactic used by insurance companies to devalue valid claims, but it does not mean your case is over. In fact, under Illinois law, you have specific rights that protect you even if you were not in perfect health before the accident occurred.
Understanding the “Eggshell Skull” Rule in Illinois
The legal foundation for protecting victims with pre-existing conditions is often referred to as the “Eggshell Skull Rule.” This doctrine essentially states that a defendant (the at-fault party) cannot complain that the victim was more susceptible to injury than a typical person.
Imagine two drivers are rear-ended at the intersection of Armour Road and Route 50. One is a twenty-year-old athlete; the other is a fifty-year-old with degenerative disc disease. The impact might leave the athlete sore for a few days, while the fifty-year-old suffers a herniated disc requiring surgery. Under the law, the at-fault driver is responsible for the full extent of the fifty-year-old’s injury, even though the same impact wouldn’t have severely hurt someone else.
In legal terms, you are entitled to compensation for the aggravation of a pre-existing condition. The challenge lies in separating what was already there from what the accident caused. This requires a meticulous analysis of medical records and a strategic approach to evidence.
Does a Pre-Existing Condition Ruin My Car Accident Claim in Kankakee County?
No, a pre-existing condition does not ruin your claim, provided you can prove the accident worsened your condition. Illinois law entitles you to compensation for the aggravation of prior injuries, meaning the at-fault driver is liable for the difference between your health before and after the crash.
If you have a history of medical issues, the insurance company will inevitably try to use it against you. They will scour your medical records looking for any mention of pain in the same body part involved in the crash. However, having a bad back or a previous knee surgery does not give a reckless driver a free pass to injure you further.
To succeed in these claims, we must differentiate between the natural progression of your condition and the acute trauma caused by the collision. We focus on the concept of “aggravation.” We are not claiming the accident caused the arthritis you’ve had for a decade; we are claiming the accident turned a manageable condition into a debilitating one.
Key factors that strengthen these claims include:
- A Change in Baseline: Provide detailed medical records and personal testimony clearly illustrating that you were pain-free, or that any prior discomfort or stable symptoms were only minor and easily manageable before the crash. Crucially, this must be contrasted with your current state, where you are now experiencing significantly increased severity, frequency, or duration of pain that fundamentally and drastically impacts your quality of life and ability to engage in normal daily activities.
- New Symptoms: Demonstrate the unequivocal appearance of entirely new types of pain or neurological deficits that were completely absent prior to the accident. Examples include the onset of radiating pain (radiculopathy), persistent tingling, unexplained numbness, or demonstrable muscle weakness, particularly in areas that were entirely asymptomatic before the collision.
- Increased Treatment: Show a sudden, documented, and undeniable need for more aggressive, complex, or invasive medical intervention immediately following the accident. This includes procedures such as a series of multiple corticosteroid injections, therapeutic nerve blocks, or major, complex surgical procedures, all of which were not only not recommended but were entirely unnecessary and unheard of in your medical history before the accident occurred.
- Functional Decline: Offer concrete and irrefutable proof from multiple sources that your functional capacity has been substantially and demonstrably diminished since the crash. This evidence should include detailed physicians’ reports, objective physical therapy assessments, and compelling witness testimony detailing the loss of your ability to perform routine daily tasks, maintain your employment responsibilities, fully participate in hobbies and recreational activities, or provide necessary care for your family.
Differentiating Between Recurrence and Aggravation
Insurance adjusters love to argue that your current pain is simply a “recurrence” of old problems or the natural aging process. They might point to an X-ray showing degenerative changes and say, “This didn’t happen in the crash; this took years to develop.”
While true that bone spurs or disc degeneration take years to form, they can remain asymptomatic for a lifetime. A violent impact, such as a truck accident on I-57, can destabilize the spine, causing these previously silent conditions to flare up aggressively.
We must clearly distinguish between three scenarios:
- Recurrence: The complete return of symptoms, manifesting exactly as they were before a prior treatment or period of stability. This type of claim is often the most difficult to prove, as it suggests the new injury is merely a continuation of the old one rather than a new or worsened condition.
- Aggravation: A permanent or temporary worsening of a pre-existing medical condition that was stable, asymptomatic, or not significantly impacting the individual’s life before the accident. This is a common and often successful argument, as the accident clearly made a previous issue worse.
- Acceleration: When an accident significantly speeds up the natural progression of a condition, requiring medical intervention, like surgery or joint replacement, years earlier than would have been medically necessary otherwise. This focuses on the premature nature of the required treatment caused by the trauma.
How Do I Prove the Accident Made My Old Injury Worse?
Proving aggravation requires a direct comparison of your medical records from before and after the incident. We use diagnostic imaging, treatment timelines, and testimony from your treating physicians to demonstrate a clear shift in your health status immediately following the trauma of the accident.
The success of your case depends heavily on the quality of your medical evidence. In Bourbonnais, this often involves gathering records from local providers like Riverside Medical Center or Ascension Saint Mary’s Hospital to build a timeline.
Subjective complaints of pain are important, but objective medical data is harder for insurance companies to dispute. We look for concrete changes in your medical profile.
- Diagnostic Comparisons: Comparing an MRI from three years ago to one taken after the accident is a critical step. This visual evidence can definitively show new herniations, disc bulges, tears, or other structural damage that did not exist in the prior scans, even if the area already showed signs of age-related or pre-existing degeneration. This directly challenges the claim that the injury is merely a continuation of a past condition.
- Medication History: A sudden, verifiable change in prescription usage is a strong indicator of an acute injury or severe aggravation. For example, if you hadn’t filled a prescription for strong pain medication in two years, but then refilled it three times in the month immediately following the accident, this pattern strongly suggests an acute aggravation of a prior condition or a new injury requiring intervention.
- Provider Notes: We meticulously scrutinize your treating doctor’s files for specific notations where they actively differentiate your new, post-accident symptoms from your past medical history. A powerful piece of evidence is a doctor noting, “patient reports new onset of sharp, shooting pain radiating down the leg, a distinct change from the chronic, dull ache previously managed,” which clearly establishes a baseline change caused by the recent trauma.
The Role of “The Gap in Treatment”
One of the biggest hurdles in pre-existing condition cases is a gap in treatment. If you are injured in a collision on Kinzie Avenue but wait three weeks to see a doctor, the insurance company will argue that your pain is just your “old injury acting up” and not related to the crash.
Immediate medical attention documents the trauma. Even if you think your soreness is just your old arthritis, you should be evaluated. Explain to the emergency room staff or your primary care physician that you were in an accident and that your pain has increased or changed. This creates a contemporaneous medical record linking the crash to the aggravation of symptoms.
Will the Insurance Company Look at My Entire Medical History?
Yes, once you claim a body part was injured, the insurance company will likely request 5 to 10 years of prior medical records to find evidence of pre-existing issues. They use blanket authorizations to search for any previous complaints to argue that your current injury is chronic rather than acute.
Be very careful when signing medical authorizations sent by the other driver’s insurance company. These “blanket” authorizations often allow them to access your entire medical history, including sensitive information that has nothing to do with the accident, such as mental health records or gynecological history.
They are looking for “prior complaints.” If you complained of neck pain to your family doctor five years ago because you slept wrong, the insurance adjuster might try to use that single note to argue your current herniated disc is a “chronic issue.”
Why Medical Experts Are Essential
In cases involving pre-existing conditions, the testimony of a medical professional is often the deciding factor. A general practitioner might note that you have pain, but an orthopedic specialist or a neurologist can explain the mechanism of injury.
We frequently work with medical professionals who can explain to a jury or an adjuster how the forces of a car accident interact with a compromised spine or joint. They can explain that while your spine had “wear and tear” (spondylosis), the crash caused the structural failure (herniation) that is causing your current disability.
This medical narrative counters the insurance company’s attempt to label everything as “degenerative.” We force them to acknowledge that a person can have a degenerative condition and still suffer a traumatic injury.
Protecting Your Claim Against Unfair Denials
If you receive a denial letter based on a pre-existing condition, do not accept it as the final word. It is essentially an opening negotiation tactic. The insurance company is betting that you do not know the law and will simply go away.
To protect your potential recovery, you should take the following steps:
- Be Honest with Your Doctors: Never try to hide a past injury from your doctor. Full disclosure is crucial. If the defense later discovers you withheld information about your medical history, your credibility will be severely damaged, and your entire case will likely fail. Be upfront and specific: “I had back surgery ten years ago, but I have been completely symptom-free and physically active until this recent crash.”
- Document Your Limitations: Keep a detailed, regular journal of the specific activities you cannot do now that you could perform easily before the accident. Did you have to stop a favorite hobby like gardening, running, or playing a musical instrument? Can you no longer comfortably lift your grandchildren, carry groceries, or stand for long periods? These “loss of enjoyment of life” and “loss of normal life” details are vital, as they help a jury and the insurance company clearly distinguish your healthy, pre-accident life from your current, post-accident reality.
- Consult an Attorney Before Giving a Statement: Insurance adjusters are professionals trained to ask deliberately leading and complex questions designed to elicit admissions that your current pain is “just a temporary flare-up” or “just like before” your previous injury. Having experienced legal representation ensures that you are properly prepared, and that you do not inadvertently make a statement during a recorded interview that could severely damage or destroy the viability of your claim.
Moving Forward with Your Case
A pre-existing condition does not define your value as a plaintiff, nor does it absolve a negligent driver of their responsibility. Whether you were injured on a rural road in Kankakee County or a busy intersection in Bourbonnais, you deserve to be restored to the position you were in immediately before the crash, not the position the insurance company wishes you were in. We understand the medical complexities involved in differentiating old injuries from new trauma. We know how to read the medical records, what evidence is necessary to prove aggravation, and how to counter the deceptive tactics used by insurance carriers to deny coverage.
