Accidental Death and Dismemberment (AD&D)

Accidental death and dismemberment coverage, commonly written AD&D, is insurance that pays a stated benefit when the insured dies or suffers a specified physical loss as the result of an accident. The National Association of Insurance Commissioners defines it as "an insurance contract that pays a stated benefit in the event of death and/or dismemberment caused by accident or specified kinds of accidents." The contract sets a principal sum, which is the amount payable for accidental death, and then a schedule expressing every other covered loss as a fraction of it.

It is a narrow product by design, and the narrowness is entirely in the word "accident". A policy that pays a six-figure sum after a car crash pays nothing at all when the same insured dies of heart disease a year later. That is the single most important thing to understand about it, and the reason it sits alongside life insurance rather than in place of it.

The schedule is the product, and it is written as fractions of one number. A typical schedule pays the full principal sum for accidental death and for the loss of two limbs, of the sight of both eyes, or of one limb and the sight of one eye; half for the loss of one limb or the sight of one eye; and smaller fractions for the loss of a thumb and index finger, of hearing in both ears, or of speech. Contracts also differ on whether "loss" means severance or includes permanent loss of use, which changes the answer for a paralyzing injury and is worth checking before the schedule's percentages are compared. NAIC's model regulation for supplementary health insurance adds a rule that keeps the schedule honest: "Specific dismemberment benefits shall not be in lieu of other benefits unless the specific benefit equals or exceeds the other benefits", so a scheduled dismemberment payment cannot be used to displace a larger benefit otherwise payable under the same contract.

There is a clock, and it is not on the benefit schedule. The same model regulation provides that "[a]ccidental death and dismemberment benefits shall be payable if the loss occurs within ninety (90) days from the date of the accident, irrespective of total disability." A death or a loss that arrives outside the window the contract sets can fall outside the coverage even though the accident plainly caused it. The shape to have in mind is the insured who is gravely injured in an accident, survives on support for months, and dies after the period has run. That regulation reaches individual and group supplementary health coverage, including accident-only and specified accident policies, and expressly does not reach Medicare supplement, long-term care or TRICARE supplement coverage. The clock on any particular policy is the one printed in that policy.

The exclusions are where claims are actually decided. Contracts define an accident, usually as something sudden, unexpected and external, and then remove a familiar list of circumstances: intoxication or driving under the influence, self-inflicted injury and suicide, injury sustained while committing an illegal act, war and acts of war, and aviation other than as a fare-paying passenger on a scheduled flight. Several of these matter more than they look. A single-car crash with a blood alcohol reading above the state limit sits squarely inside that list, and a claim on it fails not because the death was not accidental but because the contract removed it. Reading the exclusions is the whole of due diligence here, because the schedule is easy to read and the trigger is not.

Federal regulation treats it as a species rather than a category, which is why it is easily confused with accident insurance. 45 CFR 148.220(a)(1) lists "[c]overage only for accident (including accidental death and dismemberment)" among benefits excepted from the federal health insurance requirements, so accidental death and dismemberment coverage sits inside the accident category rather than beside it. The regulatory consequences of that placement belong to the accident insurance page. What separates the two products in the market is simple enough: an accident policy generally pays a schedule of amounts for injuries and treatment, while accidental death and dismemberment coverage pays a lump sum for death or for a listed permanent loss.

Most people who hold it hold it through work, and that changes the claims process rather than the coverage. Voluntary AD&D is commonly offered at open enrollment as a multiple of salary alongside group life, at a price low enough that the enrollment decision gets little thought. A plan an employer maintains to provide benefits in the event of accident or death is an employee welfare benefit plan under 29 U.S.C. 1002(1), which brings it inside ERISA. The practical consequence is procedural: the plan must give a claimant a written notice of denial and a full and fair review, and the claimant works through that internal appeal before a court is available. Timelines, the evidence the plan considered, and the reasons stated in the denial letter all matter more in that setting than they would on an ordinary contract claim.

Whether a workplace policy is inside ERISA is a question with a real answer, and it is not always yes. The Department of Labor's regulation at 29 C.F.R. 2510.3-1(j) carves a group or group-type insurance program out of the definition where four conditions all hold: the employer makes no contributions, participation is completely voluntary, the employer's sole functions are, "without endorsing the program", to let the insurer publicize it and to collect premiums by payroll deduction, and the employer receives no consideration beyond reasonable compensation for the payroll administration. Employee-pay-all voluntary coverage is exactly the shape that safe harbor was written for, so a policy sold at open enrollment does not become an ERISA plan simply by being sold there. The distinction decides which body of law governs a denied claim and which remedies are available, and it turns on the employer's role rather than on the policy's terms.

The tax treatment of a dismemberment benefit is settled and worth knowing. Where the coverage is employer-provided, 26 U.S.C. 105(c) excludes from gross income amounts that "constitute payment for the permanent loss or loss of use of a member or function of the body, or the permanent disfigurement" of the taxpayer, a spouse or a dependent, and that "are computed with reference to the nature of the injury without regard to the period the employee is absent from work." An AD&D schedule satisfies both tests by construction, because it pays by body part and pays the same amount whether the insured returns to work the next month or never. Where the insured bought the coverage personally rather than through an employer, 26 U.S.C. 104(a)(3) reaches the same result by the other route, excluding amounts received through accident insurance for personal injuries except to the extent the employer paid for them.

1. A principal sum is set, either as a flat amount on an individual policy or, at work, as a multiple of salary elected at enrollment.

2. A schedule assigns every covered loss a fraction of that sum. The full sum for accidental death and for the most severe combinations of loss, half for a single major loss, smaller fractions below that.

3. An accident occurs, and the event has to meet the contract's own definition of an accident, not the ordinary meaning of the word.

4. The loss has to occur inside the contract's window. NAIC's model for supplementary health coverage requires payment where the loss occurs within ninety days of the accident; the policy states its own period.

5. The exclusions are applied. Intoxication, self-inflicted injury, illegal acts, war and non-commercial aviation are the usual list, and this is the step where claims fail.

6. The benefit is paid to the named beneficiary for a death, or to the insured for a dismemberment.

A hypothetical. Aiden elects AD&D at two times his $85,000 salary, giving a principal sum of $170,000, at a cost of $2.60 a month, or $31.20 a year. His schedule pays the full principal sum for accidental death, 50 percent for the loss of one hand, and 25 percent for the loss of the thumb and index finger of one hand. A workshop accident costs him his left hand, and the policy pays 50 percent of $170,000, which is $85,000, to him rather than to a beneficiary. Because his employer provides the coverage, section 105(c) excludes that payment from his gross income, since it is computed by reference to the injury rather than to time away from work. Had the same accident cost him only the thumb and index finger, the schedule would have paid 25 percent of $170,000, or $42,500. The salary, the rate and the schedule percentages are invented for the arithmetic; the structure is the point.

The follow-through is to size the coverage against what it can actually be called on to do. In 2024 the National Center for Health Statistics recorded 3,072,666 deaths in the United States, of which 197,449 were classified as accidents, the third-ranked cause. That is roughly one death in sixteen, and a policy's contractual definition of an accident is narrower than the statistical category, since the exclusions remove a real share of it. Coverage that answers a minority of causes at a low price is a reasonable addition to a plan and a poor foundation for one.

Pros

• Group premiums are very low, so the cost of being wrong about it is small.
• The benefit is a lump sum paid on a published schedule, so what a given loss pays can be known before buying.
• It pays for dismemberment while the insured is alive, which ordinary life insurance does not do at all.
• Where the employer provides the coverage, a dismemberment benefit is excluded from gross income under section 105(c), and coverage bought personally reaches the same result under section 104(a)(3).
• Enrollment at work is usually guaranteed issue, so health history does not affect eligibility or price.

Cons

• It pays nothing when the cause of death is illness, which is the great majority of deaths.
• The exclusions do the real work, and the commonest of them, intoxication, covers a category of accidents people assume is covered.
• A loss occurring outside the contract's window after the accident can fall outside the coverage even though the accident caused it.
• Bought at work it usually ends when the job does, so it is not coverage a household can plan around.
• Its low price makes it easy to buy as though it were life insurance at a discount, which is the mistake the product invites.
• Contracts differ on whether a covered "loss" requires severance or includes permanent loss of use, and the difference decides the answer for a paralyzing injury.
