This is the amount you pay for your health insurance coverage. Premiums are typically paid on a monthly, quarterly, or annual basis.

The deductible is the amount you must pay out of your own pocket before your insurance coverage kicks in. The higher the deductible, the lower your premium, but the more you'll have to pay for medical expenses upfront.

A copayment is a fixed amount you pay for specific healthcare services or prescriptions. It's a cost-sharing mechanism between you and the insurance company.

Coinsurance is the percentage of costs you share with your insurer after meeting your deductible. For example, if you have a 20% coinsurance, you'll pay 20% of the bill, and the insurer covers the remaining 80%.

Health insurance plans often have a network of healthcare providers and facilities. Staying within the network usually results in lower out-of-pocket costs, while going out of network may be costlier.
