Insurance companies love to use pre‑existing conditions as an excuse to deny or reduce personal injury claims. But here’s the truth: having a pre‑existing condition does NOT ruin your case in California. In many situations, it can actually strengthen your claim — especially when an accident makes your condition worse.
This guide explains how California law treats pre‑existing injuries, what evidence matters most, and how Infinity Law Group protects victims from insurance company tactics.
California Law Protects Victims With Pre‑Existing Conditions
California follows the “Eggshell Plaintiff Rule.” This means:
The at‑fault party must take the victim as they find them — even if the victim was more vulnerable to injury.
In other words:
- If you had a bad back and a crash made it worse → the defendant is responsible.
- If you had prior knee issues and a fall aggravated them → the defendant is responsible.
- If you were more easily injured because of a condition → the defendant is STILL responsible.
Insurance companies hate this rule — but California courts enforce it.
Common Pre‑Existing Conditions Involved in Personal Injury Claims
Pre‑existing conditions are extremely common. They include:
- Prior back injuries
- Degenerative disc disease
- Arthritis
- Old fractures
- Previous concussions
- Chronic pain conditions
- Anxiety or PTSD
- Prior surgeries
- Herniated discs
- Old soft‑tissue injuries
These conditions do not disqualify you from compensation.
How an Accident Can Aggravate a Pre‑Existing Condition
California law distinguishes between:
1. Aggravation of a Pre‑Existing Condition
The accident made your condition worse.
2. Exacerbation of Symptoms
The accident triggered pain or symptoms that were previously under control.
3. New Injuries on Top of Old Ones
The accident caused additional harm.
In all three situations, the at‑fault party can be held liable.
How Insurance Companies Try to Use Pre‑Existing Conditions Against You
Insurance companies often argue:
- “Your pain is from your old injury.”
- “Your condition existed before the accident.”
- “You would have had these symptoms anyway.”
- “Your medical records show prior issues.”
These arguments are designed to reduce your settlement — not reflect the truth.
Infinity Law Group knows how to shut these tactics down.
How to Prove an Accident Worsened a Pre‑Existing Condition
Strong evidence is the key to winning these cases.
1. Medical Records Before and After the Accident
Comparing records shows exactly how the injury changed.
2. Diagnostic Imaging
MRIs, CT scans, and X‑rays can reveal new damage.
3. Doctor Testimony
Your doctor can explain how the accident worsened your condition.
4. Pain Journals
Daily notes help document changes in pain levels and mobility.
5. Witness Statements
Family, friends, and coworkers can describe how your condition changed after the accident.
Infinity Law Group organizes and presents this evidence in a way that insurance companies cannot ignore.
What Compensation You Can Recover With a Pre‑Existing Condition
Victims may be entitled to:
Economic Damages
- Medical bills
- Surgery and treatment
- Physical therapy
- Medication
- Lost wages
- Reduced earning capacity
Non‑Economic Damages
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
- Worsening of prior symptoms
Punitive Damages
Available when the at‑fault party acted with extreme recklessness (e.g., DUI).
Why Pre‑Existing Conditions Can Actually Increase Settlement Value
If an accident worsens a vulnerable area of the body, the resulting injuries are often more severe — and more expensive to treat.
This can increase:
- Medical costs
- Recovery time
- Pain and suffering
- Long‑term disability
Insurance companies may try to argue the opposite, but California law is clear:If the accident made your condition worse, you deserve compensation.
