When an accidental death and dismemberment claim is denied, one of the most frustrating explanations is also one of the vaguest: the insurer says the loss was “not an accident.” Families often read that phrase and feel blindsided. The event looked sudden. It caused catastrophic harm. And yet the carrier reframes the entire claim around foreseeability, intent, medical causation, intoxication, or some version of “this was not accidental under the policy.”
That kind of denial can be challenged. In general terms, the appeal often turns less on emotion and more on policy language, medical and factual records, the insurer’s reasoning, and the legal standard that applies to the claim. If you are looking for a broader foundation on how these disputes develop, this overview of how accident definitions, exclusions, and causation fights shape AD&D denials can help frame the bigger picture.
In this post you’ll learn how these denials usually work, what evidence often matters most, how ERISA and non-ERISA appeals can differ, and how to build an appeal that directly answers the insurer’s “not an accident” position.

AD&D coverage is narrower than ordinary life or disability coverage. The policy generally pays only when the death or injury results from a covered accident, often directly and independently of other causes, and not from an exclusion such as sickness, intoxication, self-inflicted injury, or criminal conduct. The National Association of Insurance Commissioners describes AD&D as coverage for death or dismemberment caused by accident rather than for every death or bodily loss generally. NAIC’s insurance glossary.
That framing gives insurers room to dispute not only what happened, but also how to characterize what happened. A carrier may argue:
These disputes matter because unintentional injury remains a major source of death in the United States. CDC data released in March 2025 showed the age-adjusted unintentional injury death rate rose sharply through 2021 and remained elevated in 2023, while motor vehicle traffic remained one of the leading methods of unintentional injury death. CDC Data Brief No. 526. NHTSA also reported on April 8, 2025 that it estimated 39,345 traffic fatalities in 2024, down from 40,901 in 2023, and separately reported that 12,429 people died in alcohol-impaired-driving crashes in 2023. NHTSA 2024 early estimates, NHTSA drunk-driving statistics.
Those numbers do not answer any single claim, but they help explain why insurers often focus heavily on accident characterization in vehicle crashes, falls, overdoses, assaults, drownings, and other sudden-loss cases.
“Not an accident” can mean several different things, and the appeal usually gets stronger when that phrase is translated into a concrete coverage argument.
Some carriers argue that even if the insured did not intend to die or suffer injury, the conduct was so risky that the result was not accidental. That issue appears often in crash cases, intoxication cases, and confrontations.
