This glossary has many commonly used insurance and medical terms, but isn’t a full list. The terms and definitions – provided by Healthcare.gov – are intended to be educational and may be different from the terms and definitions in your plan.
Some of these terms also might not have exactly the same meaning when used in your policy or plan, and in any such case, the policy or plan governs. (See your Summary of Benefits and Coverage (SBC) in the member portal for information on how to get a copy of your policy or plan document. You may also log into your member portal to view your SBC. )
You can download the Uniform Glossary (pdf) or view the terms below.
Allowed Amount: Maximum amount on which payment is based for covered health care services. This may be called “eligible expense,” “payment allowance” or “negotiated rate.” If your provider charges more than the allowed amount, you may have to pay the difference. (See Balance Billing.)
Appeal: A request for your health insurer or plan to review a decision or a grievance again.
Balance Billing: When a provider bills you for the difference between the provider’s charge and the allowed amount. For example, if the provider’s charge is $100 and the allowed amount is $70, the provider may bill you for the remaining $30. An in-network provider (anchor link) may not balance bill you for covered services.
Coinsurance: Your share of the costs of a covered health care service, calculated as a percent (for example, 20%) of the allowed amount for the service. You pay co-insurance plus any deductibles you owe. For example, if the health insurance or plan’s allowed amount for an office visit is $100 and you’ve met your deductible, your co-insurance payment of 20% would be $20. The health insurance or plan pays the rest of the allowed amount.
Complications of Pregnancy: Conditions due to pregnancy, labor and delivery that require medical care to prevent serious harm to the health of the mother or the fetus. Morning sickness and a non-emergency cesarean section aren’t complications of pregnancy.
Co-payment: A fixed amount (for example, $15) you pay for a covered health care service, usually when you receive the service. The amount can vary by the type of covered health care service.
Deductible: The amount you owe for health care services your health insurance or plan covers before your health insurance or plan begins to pay. For example, if your deductible is $1,000, your plan won’t pay anything until you’ve met your $1,000 deductible for covered health care services subject to the deductible. The deductible may not apply to all services.
Durable Medical Equipment (DME): Equipment and supplies ordered by a health care provider for everyday or extended use. Coverage for DME may include: oxygen equipment, wheelchairs, crutches or blood testing strips for diabetics.
Emergency Medical Condition: An illness, injury, symptom or condition so serious that a reasonable person would seek care right away to avoid severe harm.
Emergency Medical Transportation: Ambulance services for an emergency medical condition.
Emergency Room Care: Emergency services you get in an emergency room.
Emergency Services: Evaluation of an emergency medical condition and treatment to keep the condition from getting worse.
In-Network Provider: A provider who has a contract with your health insurer or plan to provide services to you at a discount. Check your policy to see if you can see all in-network providers or if your health insurance or plan has a “tiered” network and you must pay extra to see some providers. Your health insurance or plan may have in-network providers who are also “participating” providers. Participating providers also contract with your health insurer or plan, but the discount may not be as great, and you may have to pay more.
Medically Necessary: Health care services or supplies needed to prevent, diagnose or treat an illness, injury, condition, disease or its symptoms and that meet accepted standards of medicine.
Network: The facilities, providers and suppliers your health insurer or plan has contracted with to provide health care services.
Out-of-Network Provider: A plan to provide services to you. You’ll pay more to see an out-of-network provider. Check your policy to see if you can go to all providers who have contracted with your health insurance or plan, or if your health insurance or plan has a “tiered” network and you must pay extra to see some providers.
Out-of-Network Coinsurance: The percent (for example, 40%) you pay of the allowed amount for covered health care services to providers who do not contract with your health insurance or plan. Out-of-network co-insurance usually costs you more than in-network co-insurance.
Out-of-Network Co-payment: A fixed amount (for example, $30) you pay for covered health care services from providers who do not contract with your health insurance or plan. Out-of-network co-payments usually are more 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: Health care services a licensed medical physician (M.D. – Medical Doctor or D.O. – Doctor of Osteopathic Medicine) provides or coordinates.
Plan: A benefit your employer, union or other group sponsor provides to you to pay for your health care services.
Preauthorization: A decision by your health insurer or plan that a health care service, treatment plan, prescription drug or durable medical equipment is medically necessary. Sometimes called prior authorization, prior approval or precertification. Your health insurance or plan may require preauthorization for certain services before you receive them, except in an emergency. Preauthorization isn’t a promise your health insurance or plan will cover the cost.
Premium: The amount that must be paid for your health insurance or plan. You and/or your employer usually pay it monthly, quarterly or yearly.
Prescription Drug Coverage: Health insurance or plan that helps pay for prescription drugs and medications.
Prescription Drugs: Drugs and medications that by law require a prescription.

Skilled Nursing Care: Services from licensed nurses in your own home or in a nursing home. Skilled care services are from technicians and therapists in your own home or in a nursing home.
Specialist: A physician specialist focuses on a specific area of medicine or a group of patients to diagnose, manage, prevent or treat certain types of symptoms and conditions. A non-physician specialist is a provider who has more training in a specific area of health care.
UCR (Usual, Customary and Reasonable): The amount paid for a medical service in a geographic area based on what providers in the area usually charge for the same or similar medical service. The UCR amount sometimes is used to determine the allowed amount.
Urgent Care: Care for an illness, injury or condition serious enough that a reasonable person would seek care right away, but not so severe as to require emergency room care.
