14.4 Accidental Death & Dismemberment and Supplemental

Key Takeaways

  • AD&D pays only for losses caused by accidental bodily injury, never from sickness or natural causes.
  • The principal sum is paid for accidental death or loss of two members; the capital sum (often half) is paid for loss of one member.
  • Double/triple indemnity riders multiply the life face amount only when death is accidental.
  • Death typically must occur within about 90 days of the accident, and exclusions include war, suicide, and illness.
  • Benefits on individually owned after-tax accident policies are received income-tax-free.

Accidental death and dismemberment (AD&D) insurance and other supplemental products round out a producer's health portfolio. AD&D pays only for losses resulting from accidental bodily injury — never from sickness or natural causes — making it inexpensive but narrow. The exam emphasizes the principal-sum/capital-sum structure, the double-indemnity rider, and how supplemental coverages interact with primary plans.

The Principal Sum and Capital Sum

AD&D defines benefits around the principal sum — the full amount payable for accidental death or for the loss of two specified members. The capital sum is the lesser amount (commonly one-half of the principal) paid for the loss of one member.

LossBenefit
Accidental death100% of principal sum
Loss of two limbs or sight in both eyes100% (principal sum)
Loss of one limb or sight in one eye50% (capital sum)
Loss of thumb and index finger of one hand25% (schedule)

"Loss" of a limb generally means severance at or above the wrist or ankle, and loss of sight means total, irrecoverable blindness. Death benefits usually require death to occur within a set time (often 90 days) of the accident.

The accident must be the direct and independent cause of loss. If a covered injury is complicated by a pre-existing disease, insurers may deny or reduce the claim, arguing sickness — not the accident alone — caused the death. This sole-cause requirement is what keeps AD&D premiums low and is a recurring exam point distinguishing it from broad life coverage.

Worked Example — AD&D Payout

A policy carries a $200,000 principal sum. An insured loses sight in one eye in a covered accident — that is a single-member loss, so the capital sum applies: 50% x $200,000 = $100,000. Had the insured lost both hands, the full $200,000 principal sum would be paid.

Double Indemnity and Common Riders

  • Double (or triple) indemnity: a life-policy rider that pays two (or three) times the face amount if death is accidental. A $100,000 policy with double indemnity pays $200,000 on accidental death.
  • Common carrier benefit: an enhanced amount if the accident occurs while a fare-paying passenger on a commercial carrier (airline, bus, train).
  • Seat belt / air bag benefit: an extra fixed amount if the insured was properly restrained.

These riders pay only for accidental death; the accident must be the direct cause, independent of all other causes. Common exclusions include war, suicide, illness, and self-inflicted injury.

Other Supplemental Products

ProductWhat It Does
Accident expenseReimburses medical costs from accidents up to a limit
Travel accidentTime- or trip-limited AD&D for travel
Medicare SupplementFills Medicare deductibles/coinsurance (standardized plans)
Disability incomeReplaces lost wages during disability

These supplemental products share a common design logic: they pay defined cash or schedule benefits for a narrow trigger, carry low premiums, and stack on top of primary coverage. Travel accident and common-carrier benefits, for instance, often expire when the trip ends, while Medicare Supplement plans are standardized and renewable for life. Understanding which products are reimbursement-based and which are valued (indemnity) benefits lets a producer assemble a layered plan without creating overinsurance or coverage gaps.

Group AD&D and Taxation

AD&D is frequently sold as a low-cost group rider on group life. Key tax and structural points:

  • Individually owned AD&D / accident benefits paid for with after-tax dollars are received income-tax-free.
  • Employer-paid group AD&D follows group life rules; the cost of coverage over $50,000 may create imputed income, but accidental-death proceeds themselves are generally not taxable to the beneficiary.
  • AD&D is pure accident coverage — a death from a heart attack or cancer pays nothing, a frequent exam trap that distinguishes AD&D from ordinary life insurance.

Worked Example — Double Indemnity Trap

A $250,000 whole life policy includes a double indemnity rider. The insured dies of natural causes (cancer). The beneficiary receives the $250,000 face amount only — the rider adds nothing because the death was not accidental.

Compare an accidental death: a $250,000 policy with double indemnity pays $500,000 if the insured dies in a covered car accident within the rider's time limit. The base face amount is always paid; the rider's extra benefit hinges entirely on whether the cause was an accident as defined in the contract.

AD&D Definitions, Exclusions, and Coordination

AD&D pays only for loss caused by accidental bodily injury, never sickness. The principal sum is the full benefit paid for accidental death; the capital sum is a scheduled percentage paid for dismemberment (loss of limbs or sight). Most contracts require the loss to occur within a set window (often 90-180 days) of the accident.

Common Exclusions

Typical AD&D exclusion
War or act of war
Suicide or intentional self-injury
Illness, disease, bacterial infection (except from accidental cut)
Aviation other than as a fare-paying passenger

Worked trap - the double-indemnity rider: a life policy's accidental death (double indemnity) rider pays twice the face amount only if death is accidental, within the time limit, and not excluded. If the insured dies of a heart attack (a sickness), the rider pays nothing extra - only the base face amount is paid. Examiners build scenarios where the cause of death is a disease to test whether you know AD&D and double-indemnity benefits are accident-only.
