This glossary has many commonly used terms, but isn’t a full list. These glossary terms and definitions 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 the linked pages for plan documents specific to County-sponsored Health Plans.

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.)

Anniversary Date
The annual anniversary of when your health insurance coverage became effective.

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. A preferred provider may not balance bill you for covered services.

Benefit Period or Benefit Plan Year
This timeframe is often a calendar year for most health plans. It defines the time period when benefits for services are covered under your plan, regardless of when your coverage took effect. This period also applies to benefit maximums, deductibles, coinsurance limits and their accumulation. For example, your plan may cover 10 physical therapy sessions per benefit period, which is specified as January 1 through December 31 in your plan’s documents. So that means if you use more than 10 sessions within that time frame, the 11th session won’t be covered.

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 coinsurance 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 coinsurance payment of 20% would be $20. The health insurance or plan pays the rest of the allowed amount. Coinsurance Limit (or Maximum) - The most you’ll pay in coinsurance costs during a benefit period.

Condition

Contract
The agreement between an insurance company and the policyholder. The contract usually includes the group and employee applications, policy certificates and any riders or addenda.

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 $1000, your plan won’t pay anything until you’ve met your $1000 deductible for covered health care services subject to the deductible.
