Lifetime Limit — the maximum dollar benefit an individual may receive under a health insurance policy or plan. An example of a lifetime benefit would be a total lifetime dollar limit on benefits (such as $1 million) or limits on specific benefits (such as a $200,000 lifetime cap on organ transplants or one gastric bypass per lifetime) or a combination of the two. Once a lifetime limit is reached, the insurance plan will no longer pay for covered services. Also known as lifetime aggregate and lifetime maximum.
