Deductible - Health Insurance Definition
A Deductible is the amount you pay out of your own pocket before your insurance begins picking up any of the costs of health care. The amount of a deductible will vary from one policy to the next so be certain that you know about that before you select a health insurance policy. Deductibles are typically based on yearly health care costs and may include a different amount for families. For example, you may have a $500 per person deductible. That means you’ll pay the first $500, regardless of whether the first office visit costs that much or you make ten visits at $50 per visit.
