Glossary of Health Insurance Terms

On March 23, 2010, President Obama signed the Affordable Care Act (ACA) into law. When making decisions about health coverage, consumers should know the specific meanings of terms used to discuss health insurance. Below are definitions for some of the more commonly used terms and how the Affordable Care Act (ACA) impacts their use.

Actuarial Value (AV)

The percentage of total average costs for benefits that a plan will cover. For example, if a plan has an actuarial value of 70%, on average, you would be responsible for 30% of the costs of all in-network covered benefits. The Actuarial Value is reflected in the metallic levels of coverage, Platinum at approximately 10% insured responsibility, Gold at about 20%, Silver at 30% and Bronze at 40%.

Advance Premium Tax Credit (APTC)

A tax credit that can help you afford coverage bought through the Exchange. Sometimes known as APTC, “advance payments of the premium tax credit,” or premium tax credit. Unlike tax credits you claim when you file your taxes, these tax credits can be used right away to lower your monthly premium costs. If you qualify, you may choose how much advance credit payments to apply to your premiums each month, up to a maximum amount. If the amount of advance credit payments you get for the year is less than the tax credit you're due, you'll get the difference as a refundable credit when you file your federal income tax return. If your advance payments for the year are more than the amount of your credit, you must repay the excess advance payments with your tax return.

Annual Limit

Many health insurance plans place dollar limits upon the claims the insurer will pay over the course of a plan year. The ACA prohibits annual dollar limits for essential health benefits.

Balance billing

When you receive services from a health care provider that does not participate in your insurer's network, the health care provider is not obligated to accept the insurer's payment as payment in full and may bill you for unpaid amount. This is known as "balance billing".


The Children's Health Insurance Program (CHIP) provides coverage to low- and moderate-income children. Like Medicaid, it is jointly funded and administered by Nevada and the federal government. It was originally called the State Children’s Health Insurance Program (SCHIP).

COBRA coverage

Congress passed the Consolidated Omnibus Budget Reconciliation Act (COBRA) health benefit provisions in 1986. COBRA provides certain former employees, retirees, spouses, former spouses and dependent children the right to temporary continuation of health coverage at group rates. The law generally covers health plans maintained by private-sector employers with 20 or more employees, employee organizations, or state or local governments.


A percentage of a health care provider's contracted charge for which the patient is financially responsible under the terms of the policy.

Community rating

A way of pricing insurance, where every policyholder pays the same premium, regardless of health status, age or other factors.


A dollar amount which a patient must pay when visiting a health care provider.


Health care provider charges for which a patient is responsible under the terms of a health plan. Common forms of cost-sharing include deductibles, coinsurance and co-payments. Balance-billed charges from out-of-network physicians are not considered cost-sharing. The ACA prohibits cost-sharing in excess of $6,850 for an individual and $13,700 for a family. These amounts will be adjusted annually to reflect the growth of premiums.

Cost Sharing Reduction (CSR)

A discount that lowers the amount you have to pay for out-of-pocket for deductibles, coinsurance, and copayments. You can get this reduction if you get health insurance through the Exchange, your income is below 250% of the Federal Poverty Level, and you choose a health plan from the Silver plan category. CSRs are only available at the Silver level.  If you're a member of a federally recognized tribe, you may qualify for additional cost-sharing benefits.


A dollar amount that a patient must pay for health care services each year before the insurer will begin paying claims under a policy.

Disease management

A broad approach to appropriate coordination of the entire disease treatment process that often involves shifting away from more expensive inpatient and acute care to areas such as preventive medicine, patient counseling and education, and outpatient care. The process is intended to reduce health care costs and improve the quality of life for individuals by preventing or minimizing the effects of a disease, usually a chronic condition.


The Employee Retirement Income Security Act of 1974 (ERISA) is a comprehensive and complex statute that federalizes the law of employee benefits. ERISA applies to most kinds of employee benefit plans, including plans covering health care benefits, which are called employee welfare benefit plans.

Essential Health Benefits (EHB)

The ACA requires all non-grandfathered individual and small group plans to include all benefits within Nevada's Essential Health Benefit Benchmark Plan


Exchanges were set up as part of the ACA to connect individuals and small businesses to a variety of insurance plans from different health insurance companies, as well as offering tools and resources to help you choose the plan that's right for you or your small business.  The Nevada exchange is the Nevada Health Link which is the only health insurance resource that can provide you with federal tax credits and subsidies to help cover the cost of your insurance.

External review

The review of a health plan's determination that a requested or provided health care service or treatment is not or was not medically necessary by a person or entity with no affiliation or connection to the health plan. The ACA requires all health plans to provide an external review process that meets minimum standards.  In Nevada this is handled by the Nevada Office of Consumer Health Assistance (GovCHA).

A Full Time Equivalent calculator is available here on healthcare.gov.

Grandfathered plan

A health plan that an individual was enrolled in prior to March 23, 2010. Grandfathered plans are exempted from most changes required by the ACA. New employees may be added to group plans that are grandfathered, and new family members may be added to all grandfathered plans.

High Deductible Health Plan (HDHP)

A type of health insurance plan that, compared to traditional health insurance plans, requires greater out-of-pocket spending, although premiums may be lower. In 2016, an HSA-qualifying HDHP must have a deductible of at least $1,300 for single coverage and $2,600 for family coverage. The plan must also limit the total amount of out-of-pocket cost-sharing for covered benefits each year to $6,550 for single coverage and $13,100 for families.

The ACA extends eligibility for Medicaid for a family of four earning up to $33,465, based on the 2015 Federal Poverty Level.

Medical Loss Ratio (MLR)

The percentage of health insurance premiums that are spent by the insurance company on health care services.

During the rate review process proposed premiums are examined to ensure that they are sufficient to pay all claims, that they are not unreasonably high in relation to the benefits being provided, and that they are not unfairly discriminatory to any individual or group of individuals.


The process of voiding a health plan from its inception usually based on the grounds of material misrepresentation or omission on the application for insurance coverage that would have resulted in a different decision by the health insurer with respect to issuing coverage. The ACA prohibits rescissions except in cases of fraud or intentional misrepresentation of a relevant fact.


Group health plans may be self-insured or fully insured. A plan is self-insured (or self-funded), when the employer assumes the financial risk for providing health care benefits to its employees. A plan is fully insured when all benefits are guaranteed under a contract of insurance that transfers that risk to an insurer.
