The deductible is one of the key aspects of any good health insurance plan. It is the amount of money that you must pay each year before your plan begins to pay your expenses. Deductibles are generally available in $250, $500, $1000, $2500, $5000, and $10,000. On co-pay plans, the deductible only applies if you have to go to the hospital. On co-insurance plans, you must meet your deductible amount first, then the plan pays your bills. Choosing a deductible that fits your needs is important. You can save money with a high deductible plan, but limit your out of pocket cost with a low deductible plan.
