1. Different health insurance policies can offer different benefits, and some can limit which doctors, hospitals, or other providers you can use. All Marketplace health plans pay the full cost of certain preventative benefits even before you meet your deductible.

2. You may have to pay a deductible each plan year, which is the amount you pay for covered health care services before your insurance plan starts to pay. After you pay your deductible, you usually pay only a copayment or coinsurance for covered services. Your insurance company pays the rest. Some plans have separate deductibles for certain services, like prescriptions drugs.

3. You may have to pay coinsurance or a copayment when you get medical care, like a doctor visit, hospital outpatient visit, or a prescription. Coinsurance is usually a percentage amount (for example, 20% of the total cost). A copayment is usually a fixed amount (for example, $10 or $20 for a prescription or doctor visit).

4. Health insurance plans contract with networks of hospitals, doctors, pharmacies, and health care providers. Depending on the type of policy you buy, your plan might only pay for your care when you get it from a provider in the plan’s network, or you may have to pay a bigger share of the bill.
