Pre-Existing Conditions and Your Personal Injury Claim

Many people assume that having a pre-existing condition will prevent them from filing a personal injury claim or recovering compensation. Insurance companies often try to exploit this belief by downplaying injuries or denying claims outright. But Nevada law makes it clear: you can still seek compensation if someone else’s negligence made your condition worse or triggered new complications.

Pre-existing conditions are common. From back injuries and joint problems to anxiety or chronic illness, many individuals have some type of prior medical history. The key question is whether the accident aggravated or worsened that condition. If so, you may still be entitled to full or partial compensation.

Understanding how pre-existing conditions interact with personal injury law is essential for protecting your rights and preparing a strong case.

What Is a Pre-Existing Condition?

A pre-existing condition is any health problem, injury, or medical diagnosis that existed before the incident that caused your current claim. It may be a long-term condition or a prior injury that seemed healed but became aggravated after the new accident.

Examples include:

• Prior back or neck injuries
• Arthritis or joint degeneration
• Anxiety or depression
• Heart conditions
• Asthma or respiratory disorders
• Herniated discs
• Traumatic brain injuries (TBI)
• Previous concussions
• Diabetes or autoimmune disorders

These conditions can complicate a personal injury case, especially if the new injury affects the same part of the body or worsens symptoms.

How Nevada Law Handles Pre-Existing Conditions

Nevada follows the “eggshell plaintiff” rule. This legal principle holds that a defendant must take the injured person as they find them. In other words, if a person is more susceptible to injury due to a pre-existing condition, the at-fault party is still responsible for the full extent of the harm caused, even if a healthier person would not have been as badly injured.

This rule protects victims from being penalized simply because they were more vulnerable. However, it also places a burden on the injured person to demonstrate how the accident worsened or reactivated a previous condition.

New Injury vs. Aggravation of a Pre-Existing Condition

When evaluating a personal injury claim, medical professionals and insurance adjusters distinguish between two scenarios:

• New injury: The injury did not exist before the accident and was caused entirely by the incident.
• Aggravation of a pre-existing condition: The accident made an existing condition worse, caused flare-ups, or triggered symptoms that were previously dormant.

You may recover compensation in both cases. But the amount and type of compensation may vary based on the medical evidence and expert opinions presented.

How Insurance Companies Use Pre-Existing Conditions Against You

Insurance companies frequently try to use pre-existing conditions to reduce or deny claims. They may argue:

• Your pain is unrelated to the accident
• Your injury already existed and was not caused by the crash
• You were already receiving treatment and nothing has changed
• The accident only caused minor damage and you are exaggerating your symptoms

These tactics are meant to minimize payouts and shift blame. If you have a history of prior injuries or conditions, it is critical to work with an attorney who can counter these arguments with medical records and expert testimony.

Common Scenarios Involving Pre-Existing Conditions

Some of the most common examples of personal injury cases complicated by pre-existing conditions include:

• Whiplash after a car accident: A person with previous neck strain experiences more severe pain after being rear-ended.
• Herniated disc flare-up: A minor fall aggravates an old back injury that had previously healed.
• Knee injury recurrence: A pedestrian accident reactivates pain in a surgically repaired joint.
• Mental health relapse: A traumatic event worsens symptoms of anxiety, PTSD, or depression.
• Chronic pain flare-ups: A slip-and-fall incident causes new pain in areas previously impacted by fibromyalgia or arthritis.

In each case, the new incident made the existing condition worse or created new complications that did not exist before.

Proving an Aggravated Condition in Nevada

To succeed in a claim involving a pre-existing condition, your legal team must show:

1. You had a documented pre-existing condition before the incident
2. The accident aggravated or worsened that condition
3. The aggravation resulted in new symptoms, increased pain, or additional treatment needs
4. These changes were caused directly by the negligent actions of another party

Medical records, physician statements, and diagnostic imaging before and after the incident can help demonstrate the difference.

Types of Evidence That Strengthen Your Case

• Pre-accident medical records: Show baseline health and any pre-existing conditions
• Post-accident records: Document changes in symptoms, treatment plans, and outcomes
• Doctor’s written opinion: A statement connecting the accident to the aggravation of your condition
• Pain journals: Daily logs of pain levels and functional limitations
• Therapy and rehab records: Evidence of new or expanded treatment
• Expert testimony: Medical experts who can explain causation to a jury

Your attorney may also compare imaging scans or physical therapy records to highlight the difference in your condition before and after the accident.

Can You Still Recover Compensation?

Yes. In Nevada, injured victims may recover compensation for:

• Additional medical treatment required due to aggravation
• Loss of mobility or range of motion
• New or extended time off work
• Loss of quality of life
• Mental health impacts caused by reactivated symptoms

The compensation may be reduced if some of the medical issues existed beforehand, but you are still entitled to be made whole for any new harm that resulted from the incident.

Handling Pre-Existing Conditions During Medical Treatment

Be honest and transparent with your doctors about your medical history. Trying to hide a pre-existing condition can damage your credibility and may backfire if discovered later in the claims process. Instead:

• Clearly explain how your symptoms have changed or worsened
• Describe any new limitations or pain you didn’t have before
• Follow all recommended treatment plans
• Request that your doctor document changes in your condition

Your treating physicians play a key role in establishing the connection between your injuries and the accident.

What If You Didn’t Know About the Pre-Existing Condition?

It is possible to have a pre-existing condition you were unaware of, such as a bulging disc or a heart abnormality. If an accident reveals or exacerbates a hidden issue, the at-fault party may still be held liable for triggering your symptoms.

In these cases, diagnostic tests taken after the accident often reveal the issue. You can still seek compensation for the resulting complications and treatment, even if you had not previously reported symptoms.

Why Insurance Adjusters Focus on Medical History

Insurers often comb through years of your medical history looking for anything that can be used to cast doubt on your claim. They may request records unrelated to your current injuries or misrepresent past diagnoses.

Having legal representation protects you from unnecessary intrusions and ensures that only relevant records are shared. Your attorney can challenge efforts to minimize your claim and present your medical history in a clear, truthful, and accurate light.
