A consumer most often pays a deductible WHEN SHARING THE COST OF A PAYOUT.

A deductible is defined as an amount you pay out of pocket for medical expenses before your health insurance will pay its share.

For example, your medical expense is 3,000 and your deductible is 600. Once you pay the 600, only then will your health insurance pay their portion of 2400.
