Health insurance glossary + terms to know

A helpful guide to understanding common health insurance terms

If you are offered health insurance from your employer, it is considered "affordable" if your annual contribution (what comes out of your paycheck for the year) does not exceed (go over) 9.5% of your total gross annual household income.

If your employer offers affordable health insurance that meets minimum essential coverage requirements, you may not be eligible for certain subsidized health plan options.

Your annual medical deductible is an amount you may need to pay each benefit year before we will pay for covered services.

  • You may need to pay part or all of your medical bill(s) until you reach your total annual medical deductible.
  • If you have a family plan, your family annual medical deductible combines the annual medical deductibles paid by covered family members.

Note: A plan with a lower annual deductible will often have a higher monthly premium (and vice versa).

Your annual medical out-of-pocket maximum is a limit on the amount you need to pay for covered medical services within a benefit year.

  • Your annual deductibles (if applicable), medical co-insurance, and medical co-payments all contribute to this maximum amount.
  • Once you reach your full annual medical out-of-pocket maximum, we will pay for covered services for the remainder of the benefit year and you no longer need to pay co-payments or co-insurance for covered services. 

Keep in mind, once you reach your full annual medical out-of-pocket maximum, you are still responsible for your monthly premiums, co-payments, and co-insurance for prescription drugs.

Your annual pharmacy deductible is an amount you may need to pay each benefit year specifically for prescription drugs before we will pay for covered pharmacy costs.

Your annual pharmacy out-of-pocket maximum is a limit on the amount you need to pay specifically for covered prescriptions within a benefit year.

Once you reach your pharmacy out-of-pocket maximum, we will pay for covered prescriptions in full through the remainder of the benefit year. If you have a family plan, and a pharmacy out-of-pocket maximum, you need to reach your total family pharmacy out-of-pocket maximum before we will pay for covered prescriptions in full for all members enrolled under a family plan. However, once an individual in your family reaches their individual annual pharmacy out-of-pocket maximum, we will pay for covered pharmacy services in full for that individual.

A benefit year is the consecutive 12-month period during which health plan benefits are purchased and administered; deductibles, co-insurance, and the out-of-pocket maximums are calculated; and most benefit limits apply.

Note: In some cases, your first benefit year will not be a full 12 months.

An adult caretaker relative is a person who is:

  • Living with children under age 19 to whom they are related by blood, adoption, or marriage, or
  • A spouse or former spouse of one of those relatives, AND
  • The primary caretaker of these children when neither parent is living in the home.
  • Pregnant
  • A parent or adult caregiver
  • Disabled according to standards set by federal law
  • HIV-positive

A citizen national is a person who, though not a citizen of the United States, owes permanent allegiance to the United States. Please call the U.S. Citizenship and Immigration Services National Customer Service Center at 800-375-5283 (TTY: 800-767-1833) for more information, or visit www.uscis.gov

A health insurance plan that allows an employee who leaves a company to continue paying for coverage through their work for a certain amount of time.

Coinsurance is an amount, stated as a percentage, that you will pay for certain covered services, depending on your plan level. For example, if you have 20% co-insurance for a $100 covered medical service, then you will owe $20 at the time of the service.

ConnectorCare plans are affordable health insurance plans offered through the Massachusetts Health Connector. They have low monthly premiums and low out-of-pocket costs, with no deductibles.

A copayment is a fixed amount you may have to pay for a covered pharmacy or medical service at the time of service.

Cost sharing means you will pay for a portion of your health care costs not covered by Tufts Health Plan. The amount or percentage you pay will depend on your plan level.

A covered health service is care you need to get that we will pay for (cover).

Covered medications are drugs your doctor can prescribe that we will pay for (cover).

Your current household income is the combined income of all tax household members from all sources, including wages, commissions, bonuses, Social Security and other retirement benefits, unemployment compensation, disability, interest, and dividends.

Tip: Use the household income which you would report on your taxes for each person in your household.

A deductible is the amount that you must pay toward covered health care services before Tufts Health Plan will begin paying.

A person is considered disabled if they have a physical or mental condition that prevents or limits their ability to work for at least 12 months, and they:

An eligible resident is a person living in the United States who is eligible to apply for adjustment to permanent resident status. Please call the U.S. Citizenship and Immigration Services National Customer Service Center at 800-375-5283 (TTY: 800-767-1833) for more information, or visit www.uscis.gov

In deciding family size, MassHealth counts parents (natural, step, and adoptive) and their children under the age of 19 who live with them.

  • If you’re pregnant, MassHealth counts your unborn child (or children) as a member of your family.
  • If neither parent lives at home, a family can be children under the age of 19 and the relative(s) living at home and taking care of them.

If you are married and have no children under age 19, MassHealth and Commonwealth Care count you and your spouse.

Your household size is based on the number of personal exemptions which you would claim on your tax return during the specified year of health care coverage — regardless of how many people in your family or household will be covered under your health plan. Your household size would include yourself (or the income of the taxpayer), your spouse (if applicable), and any child or person who you claim as a tax dependent (this includes the income of any person who must report their income on a separate return but you still claim as a dependent on your tax return).

For example, if you would claim yourself, a spouse, and two children as dependents/exemptions on your tax return, your household size is four.

Inpatient medical care includes hospital or clinic treatment that requires at least one overnight stay.

Some examples may be if you are having a baby, or if you need to have surgery that requires you to stay overnight.

An integrated annual deductible is when your payments for either medical or pharmacy services both apply toward your deductible.

For example, if you have a $500 integrated annual deductible, and spend $400 on medical costs and $100 on pharmacy costs, you have met your $500 integrated annual deductible. Once you've met your integrated annual deductible, you only have to pay pharmacy or medical co-insurance or co-payments until you reach your total integrated out-of-pocket maximum.

An integrated annual out-of-pocket maximum is the maximum amount you may pay in a benefit year for both medical and pharmacy covered services. Once you reach your annual out-of-pocket maximum, you no longer need to pay co-payments or co-insurance for covered medical services. We will pay for covered medical services for the remainder of the benefit year. However, you will still need to pay your monthly premiums. Your monthly premiums do not contribute toward this maximum amount.

Check your plan to get more information about your covered services and costs. If your plan does not have an integrated annual out-of-pocket maximum, then your plan may have an annual medical out-of-pocket maximum and a separate annual pharmacy out-of-pocket maximum.

An integrated deductible is when your out-of-pocket expenses for both medical and pharmacy expenses are applied toward the same deductible total.

Your primary care provider is the doctor or other provider you see first for most health problems. They make sure you get the care you need to stay healthy. They also may talk with other doctors and health care providers about your care and refer you to them.

Prior authorization, also called “prior permission,” is the approval needed before you can get certain services or drugs. Some network medical services are covered only if your doctor or other network provider gets prior authorization from our plan. Covered services that need prior authorization are marked in the Member Handbook. Some drugs are covered only if you get prior authorization from us. Covered drugs that need prior authorization are marked in the List of Covered Drugs or Preferred Drug List.

Your projected household income is your estimate for next year of the combined income of all tax household members from all sources, including wages, commissions, bonuses, Social Security and other retirement benefits, unemployment compensation, disability, interest, and dividends.
