Deductible is one of the several types of clause that are used by the insurance company as a threshold for policy payment for health insurance or travel insurance. Deductible is a decided amount that you have to pay from your pocket while claiming the insurance. For example, you have a deductible of $500, and you have insurance coverage for $2000, then you are responsible for paying for $500 and the remaining amount $1500 will be paid by insurance company.
