When you are involved in a personal injury accident, whether it is a car crash, a slip and fall, or a workplace mishap, the path to recovering financial compensation can be complicated. If you already suffered from a medical issue before the incident occurred, the process becomes significantly more complex. Insurance adjusters frequently use prior medical issues as a shield to deny claims or reduce settlement amounts.
However, having a pre-existing condition does not automatically disqualify you from recovering compensation. Understanding the legal frameworks, the strategies employed by insurance companies, and the methods used to prove your case is essential for protecting your rights.
Understanding Pre-Existing Conditions
A pre-existing condition is any physical or mental health issue that you sustained before the accident in question occurred. These conditions can range from minor injuries that were still healing to chronic, lifelong ailments.
Common examples of pre-existing conditions that frequently surface in personal injury cases include:
-
Chronic back pain, degenerative disc disease, or past herniated discs
-
Previous bone fractures or joint injuries, particularly in the knees, shoulders, or neck
-
Arthritis and osteoarthritis
-
Traumatic brain injuries or previous concussions
-
Mental health conditions such as depression, anxiety, or post-traumatic stress disorder
-
Cardiovascular issues or diabetes, which can complicate physical recovery times
When you file a personal injury claim, the primary objective is to hold the negligent party financially responsible for the harm they caused. The presence of a prior injury changes the conversation from what injuries were caused by the accident to how much additional harm the accident inflicted upon your body.
The Eggshell Skull Rule Explained
One of the most vital legal doctrines protecting injured victims in the United States is the eggshell skull rule. This common law principle states that a defendant must take a plaintiff as they find them. In plain terms, if a victim is more susceptible to injury due to a pre-existing weakness or condition, the negligent party is still fully liable for the resulting damages.
Imagine two people are involved in identical low-speed rear-end collisions. The first person has a perfectly healthy spine and walks away with mild soreness that resolves in two weeks. The second person suffers from degenerative disc disease, and the impact causes a severe disc herniation requiring surgery. Under the eggshell skull rule, the at-fault driver cannot claim that they should not have to pay for the surgery simply because the victim had a vulnerable spine. The defendant is responsible for the actual damage inflicted, regardless of the victim’s underlying fragility.
However, a critical distinction must be made between an aggravated injury and an unrelated ongoing problem. You cannot recover compensation for the baseline pain or limitations you experienced before the accident. You can only seek compensation for the margin of worsening caused by the new event.
How Insurance Adjusters Attack Your Claim
Insurance companies operate for profit, and their primary goal is to minimize the amount of money paid out in settlements. When an insurance adjuster discovers that you have a pre-existing condition, they will immediately attempt to use it to weaken your case. They generally employ several specific tactics to achieve this.
First, adjusters will argue that your current pain is entirely a continuation of your old injury. They will meticulously review your past medical records to find any instances where you complained of similar symptoms before the accident. If you complained of lower back pain six months ago, they will assert that your current back pain is merely that same issue, completely uninfluenced by the crash.
Second, they will try to attribute your current medical treatments to your prior condition. If your doctor orders an MRI or recommends physical therapy after an accident, the insurance company may claim these interventions were inevitable due to your pre-existing health status, arguing that the accident did not trigger the need for care.
Third, adjusters often attempt to secure an overbroad medical authorization form early in the process. They may ask you to sign a release allowing them to review your entire medical history. Once they have this access, they will search for any historic illness, injury, or lifestyle factor that they can twist to minimize the perceived value of your current suffering.
Proving Worsening or Aggravation
To successfully defeat the tactics of an insurance company, you must present undeniable evidence showing exactly how the accident aggravated or accelerated your pre-existing condition. Worsening can be categorized in two primary ways:
Physical Aggravation
This occurs when a stable or managed condition is made physically worse by the trauma of the accident. For instance, if you had mild knee arthritis that allowed you to walk comfortably, but the accident caused a direct impact that tore the cartilage, you have experienced a clear physical aggravation that may now require surgical intervention.
Symptomatic Activation
This happens when a condition that was completely asymptomatic or dormant is suddenly triggered and made painful by the accident. A classic example is degenerative disc disease. Many adults have this condition without ever knowing it because it causes no pain. If a car accident suddenly causes that silent condition to become highly painful and debilitating, the defendant is liable for activating those symptoms.
Proving these changes requires a combination of robust documentation and expert testimony. Your medical records serve as the foundation. Ideally, you will have medical documentation from before the accident showing your baseline health status, coupled with immediate, detailed medical records after the accident illustrating the sudden change in your condition.
The Role of Medical Experts and Documentation
Without objective medical evidence, separating your pre-existing condition from your new injuries is nearly impossible. To build a compelling case, you must rely heavily on specialized medical documentation and professional opinions.
Diagnostic imaging plays a pivotal role in this process. X-rays, CT scans, and MRIs taken after the accident can be compared against older imaging if it exists. A radiologist or treating physician can often point to specific structural changes, such as a new tear, a fresh fracture, or acute inflammation that was not present in previous years.
Furthermore, the narrative testimony of your treating physicians is incredibly influential. Doctors can write detailed medical nexus letters explicitly stating how the mechanics of the accident caused a distinct change in your clinical presentation. They can outline how your treatment plan, medication dosages, and physical limitations increased strictly because of the new trauma.
Consistency in your own reporting is equally critical. When you visit doctors after an accident, you must be completely honest about your medical history while clearly articulating how your current pain feels different from past episodes. Inform your providers if the pain is located in a slightly different area, if it is sharper, or if it prevents you from performing activities that you were fully capable of handling the day before the incident.
Steps to Take to Protect Your Claim
If you are pursuing a personal injury claim and possess a pre-existing medical condition, taking the correct steps from the very beginning can prevent the insurance company from derailing your case.
-
Disclose your history honestly: Never try to hide a past injury from your attorney or your doctors. If you conceal a prior condition and the insurance company discovers it later through medical records, it destroys your credibility entirely. A jury or insurance adjuster will assume you are lying about the accident causing the injury.
-
Refuse to give recorded statements: Insurance adjusters are trained to ask misleading questions designed to get you to admit that your current pain feels just like your old pain. Polite but firmly decline to give a recorded statement until you have consulted with legal counsel.
-
Do not sign broad medical releases: Only provide medical records that are directly relevant to the body parts injured in the accident. Do not give the insurance company unrestricted access to your lifelong medical history.
-
Seek immediate and continuous medical care: Gaps in treatment allow adjusters to argue that your pain is from your old injury acting up naturally, rather than from the accident. Follow your doctor’s treatment plan precisely.
Frequently Asked Questions
Can I still file a claim if my pre-existing condition was already painful before the accident?
Yes, you can still file a claim. You are entitled to compensation if the accident made your existing pain significantly worse, more frequent, or harder to manage. The case will focus entirely on proving the difference between your baseline pain level before the crash and your heightened pain level after the crash.
What happens if the accident caused an entirely new injury in the same area as an old one?
If you fully recovered from an old injury years ago and the accident caused a brand new injury to that same body part, it is treated as a new injury. Your medical records showing that you had successfully completed past treatment and were living without symptoms will be vital in proving the old injury was healed.
Will my past workers’ compensation claims affect my current personal injury lawsuit?
They can affect your case if the workers’ compensation claim involved the same parts of your body. Insurance defense attorneys have access to databases that track claims history. They will pull your old workers’ compensation files to see what injuries you claimed and what permanent partial disability ratings you might have received.
How do courts calculate damages when a prior condition is aggravated?
Courts and insurance companies look at the incremental difference in your quality of life, medical expenses, and earning capacity. They evaluate the cost of the additional medical care required solely due to the accident and look at how much more restricted your daily activities are now compared to before the incident.
Should I tell the responding police officer about my pre-existing condition at the scene?
No, you do not need to explain your entire medical history to a police officer at the scene of an accident. Focus on telling the officer if you are experiencing new pain or a worsening of pain from the immediate impact. Save the detailed medical discussions for the paramedics or emergency room physicians.
Can an insurance company deny my claim completely just because I have arthritis?
They may attempt to deny it, but legally they cannot deny a claim solely based on the presence of arthritis. Under the law, if the trauma of the accident caused your stable, manageable arthritis to become severely painful or disabling, the negligent party is responsible for that sudden decline in your health status.
How far back will the insurance company look into my medical records?
Insurance companies typically request records going back five to ten years, depending on the severity of the claim and the specific body parts involved. They look for patterns of chronic pain, past surgeries, or long-term physical therapy that might overlap with your current injury allegations.
