The benefit period is the length of time that disability benefits are paid once the elimination period has been satisfied. It does not refer to the waiting time before benefits begin but rather to the duration for which benefits are available after the insured has met all requirements, including the elimination period.

The contestability period is a time frame, typically the first two years after a policy is issued, during which the insurer can contest or deny claims based on misrepresentations made by the insured. This period is not related to disability or the waiting time for benefits but rather to the validity of the insurance contract.
