Health Insurance and Medicaid Terms and Abbreviations
Health Insurance Terms
Use this glossary for easy reference of common health insurance and Medicaid terms and abbreviations.
Allowed Amount
This is the maximum amount on which payment is based for all covered health care services. This might also be called an “eligible expense,” or a “payment allowance" or a "negotiated rate."
Appeal
This is a request you make to your health insurer or health plan to review a decision has made or a grievance you have again.
Balance Billing
This is when a provider invoices you for the difference between a provider’s charge and an allowed amount. As an example, if a provider’s charge is $200 and the allowed amount is $170, the provider will bill you for the remaining $130.
Co-insurance
This is your portion of the costs of a covered health care service, usually presented as a percent (for example, 18%) of the allowed amount for a service. You then pay the co-insurance plus any deductibles. As an example, if a health insurance allowed amount for a doctor’s office visit is $150 and you have already met your deductible, your co-insurance payment of 18% would be $27. Your health insurance will pay the rest of the allowed amount.
Co-payment
A fixed dollar amount ((an example might be $25) which you would pay for a covered health care service, generally at the time you receive the service. This amount can vary a lot by the type of covered health care service.
Deductible
The dollar amount that you will need to pay for health care services that your health insurance or health plan covers before your health insurance or health plan begins to pay for services. As an example, if your deductible is $3,000, your health plan will not pay anything until you have spent your $3000 deductible for any covered health care services that are subject to the deductible. Please remember that the deductible might not apply to all services.
Durable Medical Equipment (DME)
This refers to equipment and supplies that are ordered by a health care provider to be used every day or for an extended period of time. These might include wheelchairs, oxygen equipment, testing strips for diabetics, or crutches.
Emergency Medical Condition
This is an illness, injury, symptom or existing condition that is so serious that a reasonable person will seek care right away to avoid harm.
Emergency Medical Transportation
Any ambulance service for an emergency medical condition.
Emergency Room Care

In-network Co-insurance
This is the percent (as an example, 25%) that you will pay of the allowed amount for covered health care services to providers who have contracts with your health insurance or health plan. As a rule of thumb, in-network co-insurance is more likely to cost you less than out-of-network co-insurance.
In-network Co-payment
This is a fixed amount (as an example, $20) that you will pay for covered health care services to providers who have contracts with your health insurance or health plan. As a rule of thumb, In-network co-payments are more likely to be less than out-of-network co-payments.
Medically Necessary
These are health care services or supplies that are needed to prevent, diagnose, or treat illnesses, injuries, diseases, conditions and their symptoms. They also must meet accepted standards of medicine.
Network
All the facilities, providers and suppliers with which your health insurer or health plan has contracted to provide health care services.
Non-Preferred Provider
This is a provider who does not have a contract with your health insurer or health plan. With a non-preferred provider you typically will pay more. Remember to check your policy to make sure you can go to all providers who have contracted with your health insurance or health plan. Many health insurance companies or health plans have a “tiered” network that require you pay extra to see some providers.
Out-of-network Co-insurance
This is the percent (as an example, 35%) that you pay of the allowed amount for health care services that are covered to providers who do not currently have a contract with your health insurance or health plan. Out-of-network co-insurance will usually costs you more than in-network co-insurance. Out-of-network Co-payment This is a fixed amount (as an example, $35) that you pay for health care services that are covered from providers who do not contract with your health insurance or health plan. Out-of-network copayments are generally higher than in-network co-payments.
Out-of-Pocket Limit
The most you pay during a policy period (usually a year) before your health insurance or plan begins to pay 100% of the allowed amount. This limit never includes your premium, balance-billed charges or health care your health insurance or plan doesn’t cover. Some health insurance or plans don’t count all of your co-payments, deductibles, co-insurance payments, out-of-network payments or other expenses toward this limit.
Physician Services Plan
This is a benefit that your employer, union or some other sponsoring group provides to you in order to pay for your health care services.
Preauthorization
This is a decision made by your health insurer or health plan about the medical necessity of a health care service, a prescription drug, a treatment plan, or durable medical equipment. It is sometimes called prior authorization, precertification, or prior approval. Your health insurance or health plan might require this preauthorization for specific services before you are able to receive them, with the exception of emergences. Please remember, getting preauthorization is not a promise that your health insurance or plan will cover the cost.
Preferred Provider
This is a provider who has a contracted with your health insurer or plan to provide you with services at a discount. You can check your policy to see if you can see all the preferred providers or if your health insurance or health plan are on a “tiered” network and if you must pay more to see certain providers. Your health insurance or health plan may have preferred providers designated as “participating” providers. Participating providers also have contracts with your health insurer or health plan, but the discount may not be as big, so you may have to pay more.
Premium
The amount you must pay for your health insurance or health plan. This is usually paid monthly, quarterly, or yearly.
