Insurance terms can feel like a second language. Here are the terms you will see most often, explained simply. Your own plan documents are always the final word on what applies to you.
The key terms
- Premium: the amount you pay regularly to keep your coverage active, whether or not you use care.
- Deductible: the amount you pay for covered services in a plan year before the plan starts sharing costs for many services.
- Copay: a fixed amount you pay for a specific service, such as a visit or a prescription.
- Coinsurance: a percentage of the cost you pay after your deductible has been met.
- Out-of-pocket maximum: the most you would pay for covered, in-network care in a plan year.
A simple walkthrough
Imagine a plan with a $1,000 deductible and 20% coinsurance. Early in the year you have a covered procedure that costs $1,500. You pay the first $1,000 yourself. On the remaining $500, you pay 20%, or $100, and your plan pays the rest. That is $1,100 total. The numbers here are only an example; your plan will differ.
Why copays can be confusing
Some plans charge a flat copay for primary care visits even before you meet your deductible, while other services, like imaging or lab work, may count toward the deductible instead. Check your plan summary for which services fall under which rule.
Practical tips
- Ask the office for an estimate before non-routine services.
- Preventive care is often covered at no cost to you on many plans, but confirm with your insurer.
- Keep your explanation of benefits (EOB) and compare it to any bill before paying.
- Stay in network whenever you can.
If a bill looks wrong, call the provider's billing office first. Errors happen, and asking politely is often enough to get them corrected.
