A deductible is the amount you pay for health care services before your health insurance
begins to pay.
For example, if your plan’s deductible is $1,500, you’ll pay 100 percent of eligible health care expenses until the bills total $1,500. After that, you share the cost with your plan by paying coinsurance.
After you pay your deductible, you usually pay only a copayment or coinsurance for covered services. Your insurance company pays the rest.
Generally, plans with lower monthly premiums have higher deductibles. Plans with higher monthly premiums usually have lower deductibles.
