A limit or “cap” on the total amount of benefits that may be paid for a specific service. For example, your plan might have limits on the dollar amounts of benefits it will provide (such as a plan that will pay no more than $300 for foot orthotics over the lifetime of your plan). Or, your plan may have limits on the number of times it will pay for a certain service (for example, the plan may only pay for one liver transplant per lifetime).
