Navigating health insurance can be confusing. Understanding some common terms can help.
The following list is a glossary of some commonly used health insurance terms. However, it’s not a full list. It’s intended for educational uses and may differ from the terms used in your policy or plan.
Certain terms may also not have the same meaning as your policy or plan. In these cases, your plan takes precedence. You can check your plan’s summary of benefits for information on how to get a copy of your plan or policy document.
- Affordable Care Act (ACA): This law helps more U.S. citizens get healthcare and lowers care costs.
- Allowed amount: This is the maximum amount a healthcare professional can charge for covered services. You may need to pay the difference if your healthcare professional charges more than the allowed amount. This may also be called the:
- eligible expense
- payment allowance
- negotiated rate
- Annual limit: This is the total amount your health plan can pay for covered care in 1 year.
- Appeal: This is a request for your health insurer or plan to review a decision that denies part or all of a payment or benefit.

- Benefits: These are the healthcare services that your health insurance plan covers.
- Catastrophic plan: You may be eligible for this plan type if you’re under 30 years old and qualify for a hardship or affordability exemption.
- Coinsurance: This is the share of healthcare costs you must pay. It’s usually calculable as a percentage. Generally, you pay coinsurance plus any deductibles your plan requires.
- Claim: A request you or your healthcare professional makes to your insurer to cover services or items you believe need coverage.
- Complications of pregnancy: These are conditions due to pregnancy, labor, and delivery that require medical care to prevent harm to your health or that of the fetus. Morning sickness and nonemergency cesarean delivery generally aren’t complications.
- Copayment: This is a fixed amount you pay for covered healthcare services. Generally, you make this payment at the time of service, and the amount can vary depending on the type of service provided.
- Cost sharing: This is sometimes called out-of-pocket costs. It’s your share of the costs of services that a plan covers. You must pay this amount out of pocket. Examples include:
- coinsurance
- copayment
- deductible
- Cost-sharing reductions: These are discounts that can reduce the amount you pay for certain services covered by an individual plan you purchase through the Marketplace. You may receive discounts if your income falls below a certain level, you choose a Silver level care plan, or you belong to a recognized tribe, including being a shareholder in an Alaska Native Claims Settlement Act corporation.
Example of cost sharing
This example helps explain how cost sharing works between you and your insurer.
Jane’s insurance plan coverage period runs from January 1 to December 31. She visits the doctor, but still needs to meet her plan’s deductible.
The cost of the doctor’s visit is $125. Jane pays the entire amount, and her plan pays nothing. Jane then pays for more services, like prescriptions.
She meets her plan’s deductible of $1,500. This means when she goes for another doctor’s appointment, she must only pay 20% of the total cost. This visit is $75. Jane pays $15, and her insurance plan pays $60.
Between paying for prescriptions and other covered services, Jane meets her plan’s out-of-pocket limit of $5,000. This means that for the rest of the coverage period, Jane pays nothing for covered healthcare services. For example, she has another visit to a doctor, which costs $200. Jane pays $0 for this visit, and her insurance plan pays the entire $200.
- Deductible: This is an amount you owe, typically annually, for covered healthcare services before your insurance plan pays. An overall deductible applies to all or most covered items and services. However, a plan may also have only separate deductibles.
