Get to Know Health Care

Health care – and taking care of your health – can be a challenge. Our Good4You Health Library, a one-stop shop for everything from in-depth health information, to healthy recipes, videos, and even a symptom tracker, can help. Use it whenever you need it. It makes us feel good to be Good4You.

We know health care language can be confusing. That’s why we pulled together a list of some of the most common terms you should know. See our glossary below.


The health care items or services covered under a health insurance plan.

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 coinsurance plus any deductibles you owe. The health insurance or plan pays the rest of the allowed amount.

An amount you may be required to pay as your share of the cost for a medical service or supply, like a doctor’s visit, hospital outpatient visit, or a prescription drug. A copayment is usually a set amount, rather than a percentage.

Cost Sharing
The share of costs covered by your insurance that you pay out of your own pocket. This term generally includes deductibles, coinsurance, and copayments, or similar charges, but it doesn’t include premiums, balance billing amounts for non-network providers, or the cost of non-covered services. Cost sharing in Medicaid and CHP also includes premiums.

Covered Services
The general term used to mean all of the health care services and supplies that are covered by our plan.

The amount of expenses that must be paid by you before an insurer will pay any expenses. The deductible applies before any coinsurance or copayments are applied.

The facilities, providers and suppliers your health insurer or plan has contracted with to provide health care services.

Open Enrollment Period
The period of time during which individuals who are eligible to enroll, can enroll in a plan.

Out-of-Network Provider or Out-of-Network Facility
A provider or facility with which we have not arranged to coordinate or provide covered services to members of our plan. Out-of network providers are providers that are not employed, owned, or operated by our plan or are not under contract to deliver covered services to you.

The amount that must be paid for your health insurance or plan. You and/or your employer usually pay it monthly, quarterly or yearly.

Primary Care Provider (PCP)
Your primary care provider is the doctor or other provider you see first for most health problems. He or she makes sure you get the care you need to keep you healthy. He or she also may talk with other doctors and health care providers about your care and refer you to them.
