Working with health insurance can be confusing. At times, you might feel like there’s a whole new language to learn. To make it easier, here’s a list of common terms and what they mean.

Coordination of Benefits (COB):
A process of figuring out which of two or more insurance policies has the main responsibility of processing or paying a claim and how much the other policies will contribute.
Copayment/Copay:
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.

Effective Date:
The date your insurance plan starts covering you.

  • These include:

    • Ambulatory (outpatient) care
    • Emergency services (including emergency room care)
    • Hospitalization
    • Maternity and newborn care

Network:
The facilities, providers and suppliers your health insurer or plan has contracted with to provide health care services.
Open Enrollment Period:
The time when you can choose to enroll in a health plan or re-enroll in a health plan you are already in.
Out-of-pocket Maximum:
The most you could pay during a coverage period (usually one year) for your share of the costs of covered services. This limit never includes your premium, balance-billed charges or health care your health insurance or plan doesn't cover.
