What Insurers Look for When Reviewing Accidental Death Claims Involving Medical Events

Losing a loved one is painful enough. When an insurer denies the accidental death benefit you were counting on, the grief turns into frustration and financial worry. Insurance companies often point to a medical event, a pre-existing condition, or a substance in the bloodstream to argue that the death was not truly “accidental.”

If you are a beneficiary facing this kind of denial, you have rights, and a denial is rarely the final word. This blog explains the four factors insurers weigh most heavily when a medical event is involved, and how each one can be challenged.

Insurers typically focus on:

• Illness contribution: Whether a pre-existing condition or underlying illness played a role in the death.
• Autopsy reports: What forensic findings say about the true cause of death.
• Toxicology: Whether prescribed or non-prescribed substances triggered a policy exclusion.
• Proximate cause: Which single cause the law treats as the real reason for the death.

How Illness Contribution Affects an Accidental Death Claim

Accidental death and dismemberment (AD&D) policies pay benefits when death results from an accident. The trouble starts when the deceased had a health condition, because most policies contain a clause excluding deaths “caused or contributed to” by illness or disease.

Insurers lean on this clause aggressively. If your loved one had heart disease, diabetes, cancer, or any chronic condition, the insurer may argue that the illness, not the accident, caused the death.

Why “Contributed To” Language Is So Heavily Disputed

The phrase “contributed to” is broad, and insurers stretch it well beyond its fair meaning. A person can have a manageable health condition and still die from a genuine accident that has nothing to do with it.

What this means for you: A pre-existing condition does not automatically defeat your claim. The question is whether the accident, independent of the illness, caused the death. Strong medical evidence and a clear account of the accident can separate the two.

The Role of Autopsy Reports in Accidental Death Claims

Forensic findings carry significant weight in any accidental death dispute. Insurers treat the autopsy report and the medical examiner’s conclusions as central proof of what happened, and they will read those documents in whatever way supports a denial.

A careful, independent review of the same report often tells a very different story.

How Post-Mortem Redistribution Can Skew the Findings

Autopsy and toxicology results are not always as reliable as insurers claim. Post-mortem redistribution is a known forensic phenomenon: after death, substances stored in body tissues and organs can migrate into the blood, artificially inflating the levels that show up in testing.

This matters enormously. A toxicology report based on post-mortem blood can overstate how much of a substance was actually in the person’s system before death. The body can also ferment blood sugar into alcohol after death, creating readings that never reflected the living person.

Michael Bartolic has demonstrated exactly these flaws in real cases, using the science of post-mortem redistribution and fermentation to dismantle an insurer’s reliance on misleading numbers.

What this means for you: Do not accept the insurer’s reading of an autopsy at face value. Interviewing the medical examiner, examining how samples were collected, and applying forensic science can reveal that the report supports an accidental death after all.

How Toxicology Influences Insurer Decisions

Toxicology results are among the most common reasons insurers deny AD&D claims. Many policies exclude deaths involving drugs, alcohol, or “voluntary” ingestion of a substance, and insurers apply these exclusions broadly.

The presence of a substance does not tell the whole story, though, and insurers frequently misuse these findings.

Prescribed Versus Non-Prescribed Substances

Insurers treat prescribed and non-prescribed substances very differently, and both can be challenged:

• Prescribed medications: If your loved one took medication as directed, an insurer should not treat that as a disqualifying “voluntary” act. Therapeutic use under a doctor’s care is not the same as misuse.
• Non-prescribed substances: Even when an unprescribed substance is present, the insurer must still prove it actually caused the death, not merely that it appeared in the report.
• Accidental ingestion: Many overdoses are genuine accidents. The person did not intend the result, which can keep the death within the policy’s accidental coverage.

How Insurers Misuse Substance Exclusions

Insurers often assume the worst. They may label a death intentional or reckless based on a single toxicology number, ignore post-mortem redistribution, or apply an exclusion without proving the substance was the real cause.

In one case, Bartolic Law helped a widow recover the full accidental death benefit after her husband died from a fentanyl overdose. We investigated the scene, interviewed the medical examiner, and showed that the fentanyl tablets had been mistaken for aspirin, proving the ingestion was accidental rather than intentional.

What this means for you: A substance in the toxicology report is not proof that an exclusion applies. The insurer carries the burden, and that burden is often far harder to meet than it first appears.

Understanding Proximate Cause in Accidental Death Claims

When more than one factor contributes to a death, the law has to decide which cause counts. This is where the doctrine of efficient proximate cause comes in, and it sits at the heart of many denials.

What Is the Efficient Proximate Cause Standard?

The efficient proximate cause is the dominant, primary cause that sets the entire chain of events in motion. If an accident is the efficient proximate cause, the death qualifies as accidental, even if an illness played some minor role along the way.

Insurers try to flip this analysis. They highlight any health condition and argue it was the “real” cause, hoping to push the accident into the background. The legal question is which cause truly drove the death from start to finish.

How Insurers Use Proximate Cause to Deny Claims

A common insurer tactic looks like this: the deceased had a medical condition, an accident occurred, and the insurer claims the underlying illness was the controlling cause. By framing the illness as primary, they invoke the disease exclusion and deny the claim.

Countering this requires building a clear causal narrative supported by medical and forensic evidence, showing that the accident, not the illness, was the efficient proximate cause of death.

What this means for you: Proximate cause is a legal standard, not just a medical opinion. How the cause of death is framed and argued can change the outcome of your claim entirely.

Talk to Bartolic Law About Your Accidental Death Claim

A denial built on a medical event, an autopsy reading, or a toxicology report is not the end of your case. These arguments are often weaker than insurers want you to believe, and the right evidence can turn a denial into a payment.

Bartolic Law has recovered accidental death benefits for families in exactly these situations, including cases involving illness, falls, and substance-related deaths. We know how insurers build these denials, and we know how to take them apart.
