What If the Crash Made an Old Injury Worse?
A prior injury does not prevent you from bringing a Michigan accident claim. If the crash made an existing condition worse, you may seek compensation for the additional harm the accident caused. The key is to show how your condition changed after the accident, not to pretend the earlier problem never existed.
Many people worry that an old back problem, prior surgery, arthritis, or another health condition will hurt their accident claim. If you have a Michigan car accident claim involving a pre-existing condition, you can still seek compensation if the crash caused a new injury or made an existing condition worse.
The focus is on the change that the crash caused. Medical records from before and after the accident can help show that change. If an insurer is blaming everything on an old condition, a Michigan car accident lawyer can explain what evidence may strengthen your claim.
Key Takeaways for Pre-Existing Conditions and Michigan Accident Claims
- A pre-existing condition does not automatically prevent you from recovering compensation after a Michigan crash.
- Michigan law allows compensation when an accident aggravates a pre-existing injury.
- The eggshell plaintiff rule means the at-fault driver generally takes you as you are, even if you were more vulnerable to injury than someone else.
- Before-and-after medical records can help show what changed because of the crash.
- PIP benefits and a claim against the at-fault driver follow different rules, so a prior condition can affect each claim differently.
Can You Still Recover If You Had a Prior Injury?
You can still recover if the crash caused a new injury or worsened an old one. You do not have to prove that you were in perfect health before the collision.
For example, you may have had occasional back pain before the crash but needed only limited treatment. If the collision caused much worse pain, more frequent care, lost work, or new physical limits, the claim can focus on that added harm.
The same idea applies to a prior knee injury, arthritis, an old shoulder problem, or an earlier concussion. The question is what changed after the crash and whether the evidence connects that change to the accident.
Michigan's Eggshell Plaintiff Rule Protects People Who Were Already Vulnerable
The eggshell plaintiff rule in Michigan means an at-fault driver generally must take you as you are. The at-fault driver is not let off the hook simply because your body was more vulnerable to injury than another person's.
Michigan's Model Civil Jury Instructions explain this principle. If the crash caused more harm because of a condition you already had, the at-fault driver may still be responsible for the harm the crash actually caused.
Suppose an old spinal injury made your back more sensitive to trauma. A crash that might cause a minor strain in someone else could cause much greater harm to you. The driver can still be responsible for that greater harm if the collision caused it.
The rule does not mean every symptom after the crash automatically becomes part of the claim. You still need evidence connecting the new or worsened problems to the accident.
How Does Aggravation of a Pre-Existing Injury Work?
The aggravation of a pre-existing injury means the crash made an existing condition worse. Michigan's jury instructions allow compensation for the additional pain, disability, and expenses resulting from that worsening.
You are not asking the at-fault driver to pay for the condition you already had. You are seeking compensation for the additional harm caused by the crash.
Comparing your condition before and after the crash
A useful way to think about the claim is to compare your life before the accident with your life afterward. If you managed an old back problem with occasional treatment before the crash but now need frequent care or cannot do activities you used to do, that change may support the claim.
Your prior records can help show what your condition was like before the crash. New records can then show what changed after the collision.
When doctors cannot cleanly separate old and new problems
Sometimes a doctor cannot determine exactly which symptoms came from the earlier condition and which resulted from the crash. That does not automatically defeat your claim.
Michigan’s jury instructions tell jurors to separate crash-related damages from a pre-existing condition when possible. If they cannot do so after careful consideration, the entire amount of those combined damages may be assessed against the defendant.
How Do Insurance Companies Use Your Medical History?
An insurer may review your prior medical records and argue that your current problems existed before the crash. That is why consistent, complete records are especially useful in a car accident claim involving a prior injury.
The insurer may:
- Compare your current symptoms with earlier treatment for the same body part
- Ask for records from before the crash
- Question whether new treatment is related to the accident
- Point to gaps in treatment or conflicting descriptions of your symptoms
None of those points automatically defeats the claim. They show why it helps to be accurate about your medical history from the beginning.
Knowing how adjusters use your medical history can help you understand why they ask about older injuries and treatment. Your lawyer can use those records to show what changed because of the crash.

What Evidence Helps Show That the Crash Made Your Condition Worse?
The strongest evidence usually shows what your condition looked like before the collision and how it changed afterward. That comparison can make it much easier to show how the crash worsened your condition.
Useful evidence may include:
- Earlier medical records showing your symptoms, treatment, and physical limits before the crash
- New medical records showing increased symptoms, new findings, or additional treatment after the crash
- Imaging or testing that shows a measurable change
- Your treating doctor's opinion about whether the crash made the condition worse
- Work records or other documents showing new restrictions or lost time after the accident
When a crash worsens an existing condition, these records can help show what changed after the collision and why the new problems are related to it.
Why honesty about old injuries helps your claim
Do not hide a prior injury from your lawyer or medical providers. If the insurer later finds records you did not disclose, the dispute can shift from what the crash caused to whether your account is reliable.
Being open about the prior condition allows your lawyer to address it directly. In many cases, the earlier records can actually help by showing that your condition was more stable before the accident.
PIP Benefits and an Injury Claim Against the At-Fault Driver Follow Different Rules
A pre-existing condition can affect your PIP benefits and your claim against the at-fault driver in different ways.
| Claim type | What it may cover | Main issue when you had a prior condition |
| PIP benefits | Certain accident-related medical expenses, wage loss, and other no-fault benefits | Whether the treatment or loss was caused by the crash |
| Claim against the at-fault driver | Pain and suffering and certain other losses when Michigan's legal requirements are met | Whether the crash caused or worsened an injury and whether you meet the serious-impairment standard |
PIP benefits
If you are eligible for PIP insurance in Michigan, it may cover reasonable accident-related medical care even when the crash aggravated an old condition. The insurer can still dispute whether a particular treatment or expense came from the accident rather than the earlier condition.
MCL 500.3107 lists the types of PIP benefits after a car accident Michigan no-fault insurance may provide, including certain medical expenses and wage loss. MCL 500.3145 also sets deadlines for pursuing unpaid PIP benefits, so a dispute should not be ignored.
Claims against the at-fault driver
Your claim against the at-fault driver can include compensation for the worsening of a prior condition. For pain and suffering after a car accident, you generally must also meet Michigan's serious impairment standard under MCL 500.3135.
This law generally requires an objectively observable impairment of an important body function that affects your general ability to live your normal life. A prior condition does not prevent you from meeting that standard if the crash caused a new impairment or made an existing one worse.
Frequently Asked Questions About Pre-Existing Conditions and Michigan Accident Claims
Do I have to tell my lawyer about old injuries?
Yes. Your lawyer needs an accurate picture of your medical history to compare your condition before and after the crash. An old injury does not automatically weaken your case, but hiding it can give the insurer a reason to question your account if it later finds the records.
Can the insurance company get my old medical records?
The insurer may request records that are relevant to the injuries or benefits involved in your claim. Michigan's no-fault law also requires medical providers to provide certain records related to a PIP claim under MCL 500.3158. Your personal injury lawyer can object when a request goes far beyond what is relevant.
What if the same body part was injured before?
You can still bring a claim if the crash caused new damage or made the old condition worse. The fact that you treated the same body part before makes the before-and-after comparison especially important.
Does a prior injury automatically reduce my settlement?
No. The value of the claim depends on the additional harm the crash caused, not simply on whether you had treatment before. Strong records can help show that the collision caused a real change in your condition, making proof after a Michigan collision important when documenting and supporting the claim.
Will I have to go to court because I had a pre-existing condition?
Not necessarily. Many accident claims resolve without a trial. A prior condition may create a dispute about what the crash caused, but medical records and other evidence can often help clarify what the crash actually caused during settlement negotiations.
Get Help When an Insurer Blames Your Injuries on the Past
A prior injury does not invalidate the new harm that an accident made worse. The important issue is how your condition changed after the accident and what evidence supports that change. Insurance adjusters often seize the opportunity to blame your condition on an old injury.
A lawyer can counter a pre-existing-condition defense by using your medical history to show what changed after the crash instead of letting the insurer treat every symptom as old.
