Accidental death and dismemberment claims often look straightforward at first. A serious fall, a crash, an on-the-job injury, a drowning, a traumatic amputation — many families reasonably assume the policy will pay if the event was clearly accidental.
But AD&D claims are often decided on proof, not just on what happened in the real world.
That distinction matters. In many claims, the insurer is not only asking whether something bad happened. It is also asking whether the records, deadlines, policy language, medical evidence, and causation story line up in a way that satisfies the contract. Under many employer-sponsored plans, the claim and appeal process is also shaped by ERISA claims-procedure rules, which require notice of the reason for denial and a chance for a “full and fair review” on appeal, but still place a lot of importance on the administrative record built before litigation begins (U.S. Department of Labor; ERISA claims procedure FAQs).
In this post, you’ll learn about seven common AD&D mistakes that can make even a potentially valid claim harder to prove, why insurers focus on them, and how an attorney may help develop a cleaner record. If you want a broader overview of how insurers fight over accident definitions, exclusions, and medical causation, this deeper discussion of how AD&D denial disputes often develop gives helpful background.

AD&D coverage is narrower than ordinary life insurance. The product typically pays only if death or a covered loss results from an accident, and many policies include exclusions involving sickness, intoxication, medical treatment, self-inflicted injury, or other disqualifying causes. The NAIC describes AD&D coverage as more limited than standard life insurance because it covers deaths only when they are accidental (NAIC insurance brief).
That narrower coverage creates familiar pressure points:
Some state insurance rules also reflect how heavily AD&D disputes can center on wording. For example, New York regulations provide that AD&D benefits may not be conditioned on “violent and external means,” and Missouri regulations likewise restrict policy language requiring accidental bodily injury to be effected solely through external, violent, and accidental means (New York regulation; Missouri regulation). Those rules do not resolve every claim, but they show that wording choices matter, and insurers often scrutinize them closely.
One of the most common mistakes is assuming the insurer will gather everything important on its own.
In practice, AD&D claims are often shaped by a relatively small set of core documents:
