What is the difference between a deductible and an out-of-pocket maximum?
The deductible is where your plan starts to share costs. The out-of-pocket maximum is where your yearly costs stop. Copayment and coinsurance describe how you pay in between. These definitions follow the HealthCare.gov glossary.
Deductible
The deductible is the amount you pay for covered health care services before your insurance plan starts to pay. With a $2,000 deductible, for example, you pay the first $2,000 of covered services yourself. After you meet it, you usually pay only a copayment or coinsurance for covered services.
Copayment (copay)
A copayment is a fixed amount, such as $20, that you pay for a covered service. Depending on the plan, a copay can apply before you meet your deductible, after you meet it, or both, for different services. For example, one plan may charge a copay for doctor visits from day one, while another charges the copay only after the deductible is met. Copays can also differ by service within the same plan, so check your plan's summary of benefits for each service you use.
Coinsurance
Coinsurance is your share of the cost of a covered service, shown as a percentage such as 20%, after you have met your deductible. So a copay is a set dollar amount, and coinsurance is a share of the bill.
