Can an Insurance Company Blame Your Injuries on a Preexisting Condition?

Yes. Insurance companies frequently argue that an accident victim’s pain came from a preexisting condition rather than the collision. That argument does not automatically defeat a Texas personal injury claim.

A preexisting condition is an injury, illness, or physical problem that existed before the accident. It may have been actively causing symptoms, controlled through treatment, or completely silent until the crash.

When I review a car accident case involving prior medical problems, I address that history directly. By comparing the person’s symptoms, treatment, and daily abilities before the collision with the changes that followed, I can determine whether the medical evidence connects the worsening condition to the crash. In many cases, that comparison turns a potential insurance defense into evidence supporting the personal injury case.

The real question is not whether the condition existed. The question is whether the accident caused a new injury, aggravated the existing condition, or made a previously manageable problem significantly worse.

Why Insurance Companies Look for Prior Injuries

Insurance adjusters understand that many adults have some history of back pain, neck pain, arthritis, prior accidents, or medical treatment. They often search the records for anything they can use to separate the current symptoms from the collision.

An adjuster may argue that:

• The pain existed before the accident
• Medical images show age-related changes
• The claimant had a similar complaint several years earlier
• A previous accident caused the current symptoms
• The collision temporarily irritated the condition without making it worse
• The recommended treatment would have been necessary anyway
• The vehicle damage was too minor to aggravate the condition

In my experience, the insurer’s argument often begins with one sentence buried in a medical record. Words such as “chronic,” “degenerative,” “history of pain,” or “prior injury” may be pulled out of context and treated as proof that the crash caused nothing.

A San Antonio car accident lawyer must be prepared to explain the complete medical history rather than allowing the insurance company to define the case through a single record or imaging report.

Texas Law Does Not Require a Perfectly Healthy Accident Victim

Texas law generally follows the rule that a person who causes an injury takes the injured person as that person existed at the time of the accident.

This principle is sometimes called the eggshell-plaintiff rule. In plain language, a negligent driver cannot avoid responsibility merely because the injured person was unusually vulnerable or had a health condition that made the post-crash consequences more serious.

The Texas Supreme Court has explained that an injured person may recover damages resulting from an accident while accounting for the victim’s physical or mental condition that existed at the time. Texas courts also recognize that a defendant may be responsible for aggravating a preexisting physical condition.

That does not mean the at-fault driver must pay for every medical problem the injured person had before the crash. Compensation is generally limited to the harm caused by the collision, including any worsening or activation of the earlier condition.

A New Injury and an Aggravated Condition Are Different

A crash can affect a preexisting condition in several ways.

The collision may cause a completely new injury

A person with a history of lower-back pain could suffer an unrelated shoulder fracture in the accident. The old back condition would not explain the newly fractured shoulder.

The collision may aggravate an active condition

An aggravation is a measurable or meaningful worsening of an existing condition.

For example, someone may have experienced occasional neck discomfort before the accident but remained able to work, exercise, sleep, and complete normal daily activities. After the collision, the person may develop constant pain, arm numbness, weakness, and a need for injections or surgery.

The earlier neck problem still matters, but it does not necessarily explain the substantial change after the crash.

The collision may activate a previously silent condition

A person may have changes visible on an old scan without experiencing pain or physical limitations before the accident. Trauma can sometimes make that previously silent condition symptomatic.

This distinction frequently arises with spinal conditions such as:

• Degenerative disc disease: age-related wear affecting the cushions between the spinal bones
• Spondylosis: age-related changes in the spine
• Spinal stenosis: narrowing around the spinal cord or nerves
• Arthritis: joint inflammation or wear that can cause pain and stiffness
• Disc herniation: displacement of material from a spinal disc that may irritate nearby nerves

The presence of degeneration on an MRI does not answer when the disabling symptoms began or whether the collision aggravated the spine. Understanding how disc herniations affect a personal injury claim requires comparing the medical findings with the person’s symptoms, physical examination, prior records, and post-accident limitations.

What Matters More Than the Diagnosis Itself?

When I evaluate these cases, the before-and-after difference often matters more than the medical label.

Consider the following comparison:

This comparison gives the medical records context. A person can have an abnormal MRI before an accident and still experience a legitimate, crash-related change afterward.

Can the Insurance Company Obtain Your Old Medical Records?

The insurance company may request prior medical records when the claim involves injuries to the same body part.

For example, if a person claims a lower-back injury, the adjuster may request records involving earlier back treatment, previous accidents, imaging studies, physical therapy, pain management, or surgery.

That does not necessarily entitle the insurer to every medical record from the person’s entire life.

An adjuster may ask the claimant to sign a broad medical authorization. This document can allow the insurance company to request records directly from healthcare providers. Some authorizations extend far beyond the injuries involved in the claim.

Before signing one, understand:

• Which providers the insurer may contact
• What records it can request
• How many years the authorization covers
• Whether it includes unrelated medical or mental-health records
• Whether the insurer may speak directly with providers
• When the authorization expires

Once a lawsuit is filed, relevant medical information may also be obtained through discovery, which is the formal process the parties use to exchange evidence. The scope of that process can be disputed and addressed through the court when necessary.

Should You Disclose a Preexisting Condition?

Yes. Be honest with your accident attorney and medical providers.

One of the most damaging mistakes I see is denying a prior injury that later appears in medical records. The underlying condition may not have defeated the claim, but an inaccurate statement can give the insurance company a credibility argument.

There is an important difference between saying:

“I never had back pain before this accident.”

and saying:

“I experienced occasional back discomfort several years ago, but I was not receiving treatment, missing work, or living with these limitations before this collision.”

The second statement provides an accurate comparison. It allows the attorney and doctor to explain what actually changed.

Tell your attorney about:

• Earlier accidents
• Prior injuries involving the same body part
• Previous surgeries
• Physical therapy or chiropractic care
• Pain-management treatment
• Earlier diagnostic imaging
• Workers’ compensation claims
• Disability applications
• Military or sports injuries
• Conditions that affected your activities before the crash

Surprises create problems. An accurate history allows the case to be prepared around the evidence that actually exists.

Prior Medical Records Can Sometimes Strengthen the Claim

Injured clients often tell me they worry that every record of prior pain or treatment will weaken their case. In practice, earlier medical records can sometimes do the opposite.

Prior records may show that:

• The earlier injury resolved
• Treatment ended years before the collision
• The person reported no continuing symptoms
• The condition was stable
• No surgery was recommended before the accident
• The person worked without restrictions
• The person remained physically active
• The earlier imaging was less severe
• The post-accident symptoms involved a new body part

In one sense, prior records can create a clear medical starting point. If the records show a stable condition before the crash followed by immediate and persistent problems afterward, they may help demonstrate the change.

What Evidence Can Prove That the Accident Made the Condition Worse?

The strongest cases usually rely on several forms of evidence rather than one medical record.

Medical records from before and after the collision

Prior records establish the person’s condition before the accident. Post-accident records document new symptoms, worsening pain, physical restrictions, diagnoses, and treatment.

The comparison can be especially important when the same body part was treated in the past.

Diagnostic images

Older and newer X-rays, MRIs, or CT scans may reveal physical changes. Imaging does not always identify the cause of pain by itself, but it can help doctors compare the condition over time.

Medical opinions

A treating doctor or retained medical expert may explain whether the crash caused a new injury or aggravated the prior condition.

Causation means the connection between the accident and the claimed injury. Complex medical conditions often require a qualified medical professional to explain that connection.

The opinion should address more than whether aggravation was merely possible. It should explain why the collision more likely than not caused the change reflected in the symptoms, examination, treatment, or imaging.

Prompt reporting of symptoms

The timing of the symptoms matters. A record showing that pain, numbness, weakness, headaches, or limited movement began immediately after the crash can help establish the sequence of events.

This is one reason prompt medical attention after a car accident matters even when a person hopes the symptoms will improve without treatment.

Work and activity records

Employment records can show that the person worked full duty before the accident but required restrictions, reduced hours, or time away afterward.

Other useful evidence may include:

• Gym or exercise records
• Sports participation
• Travel history
• Household responsibilities
• Caregiving activities
• Photographs or videos showing pre-accident activity
• Statements from coworkers, friends, or family members

These records help explain how the person functioned before and after the collision.

Evidence concerning the force of the crash

Vehicle photographs, repair estimates, event data, video, witness statements, and accident reconstruction may help explain how the body moved during the impact.

The biomechanics of car accident injuries involve the way collision forces travel through the body. This evidence can be useful when an insurer claims that the crash could not have aggravated the injured person’s condition.

What If the Vehicle Damage Was Minor?

Insurance companies often argue that minor vehicle damage means the occupants could not have suffered significant injuries.

That conclusion is too simple.

Vehicle damage and bodily injury are different questions. The visible condition of a bumper does not account for every factor affecting the occupant, including:

• The direction of impact
• The occupant’s seating position
• Whether the person was turned or reaching
• Seat and head-restraint positioning
• The difference in vehicle size and weight
• Whether the vehicle moved after impact
• The person’s age and physical condition
• A preexisting vulnerability

A low-speed collision does not prove that every claimed injury resulted from the crash. It also does not prove that no aggravation occurred. The claim must be evaluated using the complete medical and physical evidence.

Common Preexisting Conditions in Car Accident Claims

Insurance disputes frequently involve:

• Earlier neck or back pain
• Degenerative spinal conditions
• Herniated or bulging discs
• Arthritis
• Previous shoulder or knee injuries
• Prior concussions
• Migraines
• Fibromyalgia
• Osteoporosis
• Diabetes
• Earlier surgeries
• Anxiety, depression, or post-traumatic stress
• Injuries from previous car or workplace accidents

A condition such as osteoporosis, which weakens the bones, may cause a person to suffer a fracture from an impact that would not fracture a stronger bone. The person’s vulnerability does not automatically excuse the driver who caused the collision.

Mistakes That Can Weaken an Aggravation Claim

Hiding earlier treatment

Prior records are often discovered. Concealing them can damage the claimant’s credibility and prevent the attorney from addressing the issue properly.

Exaggerating the before-and-after difference

Do not claim complete health if the records show regular treatment before the crash. The better approach is to explain the actual frequency, intensity, and effect of the earlier symptoms.

Delaying medical attention

A treatment delay gives the insurer room to argue that something else caused the symptoms. It can also make it harder for doctors to determine when the condition changed.

Failing to describe the prior condition to the doctor

Doctors need an accurate history to evaluate whether the collision caused a new injury or aggravated an old one. If the physician later learns that the history was incomplete, the insurer may attack the reliability of the medical opinion.

Giving the adjuster unrestricted access to medical information

A claimant should understand the scope of any medical authorization before signing it. Relevant records may need to be produced, but that does not mean an adjuster should be allowed to search unrelated medical history without reasonable limits.

Accepting a settlement before the condition is understood

An early settlement may not account for future injections, surgery, rehabilitation, lost earning ability, or permanent restrictions. Once a release is signed, the claim usually cannot be reopened because the condition later becomes more serious.

What Compensation May Be Available?

If the evidence shows that the collision aggravated a preexisting condition, recoverable damages may include the losses caused by that aggravation, such as:

• Emergency treatment
• Doctor and specialist visits
• Diagnostic testing
• Physical therapy
• Medication
• Injections
• Surgery
• Future medical care
• Lost income
• Reduced earning ability
• Physical pain
• Mental anguish
• Physical impairment
• Scarring or disfigurement

The insurance company is not required to pay for symptoms and treatment that would have existed without the accident. The challenge is separating the earlier condition from the additional harm caused by the crash.

The value of the claim depends on the degree of aggravation, length of treatment, effect on work and daily life, future medical needs, strength of the medical opinions, available insurance coverage, and quality of the supporting evidence. Those issues are also central when evaluating an average settlement for back and neck injuries.

What I Look for When an Insurer Raises a Preexisting Condition

I begin by obtaining the records necessary to build an accurate timeline.

I want to know:

1. What condition existed before the accident?
2. When was it last treated?
3. What symptoms existed immediately before the collision?
4. Did the person have work or activity restrictions?
5. What changed after the crash?
6. How quickly were the new symptoms reported?
7. Do the medical examinations and imaging support the change?
8. Has a doctor explained the relationship between the collision and the current condition?
9. Is the recommended treatment new?
10. Can family members, coworkers, or other witnesses describe the difference?

The goal is not to pretend the earlier condition did not exist. The goal is to show clearly what the accident changed.

Final Takeaway

A well-prepared claim should establish the medical starting point, identify the new symptoms or limitations, and connect those changes to the crash through reliable evidence. That work should begin before an adjuster reduces the claim to a few unfavorable words from an old medical record.
