Health insurance is a type of insurance policy that provides financial protection for medical expenses and healthcare services.

Health insurance typically covers the cost of medical expenses such as doctor visits, hospitalization, prescription drugs, and medical procedures. The specific coverage varies depending on the policy.

A premium is the amount paid for health insurance coverage, typically paid monthly or annually.

A deductible is the amount of money you must pay out of pocket before your health insurance coverage kicks in.

A copay is a fixed amount of money you must pay for a healthcare service, such as a doctor’s visit or prescription medication.

Coinsurance is the percentage of the cost of a healthcare service that you are responsible for paying, after your deductible has been met.

An out-of-pocket maximum is the maximum amount you are responsible for paying for covered medical expenses during a given period, usually a year. Once you reach this limit, your insurance company will typically cover the rest of the costs.

A pre-existing condition is a health condition or illness that existed before you enrolled in a health insurance policy.

HMO stands for Health Maintenance Organization, which is a type of health insurance plan that typically requires you to choose a primary care physician and receive referrals to see specialists.

PPO stands for Preferred Provider Organization, which is a type of health insurance plan that typically allows you to see any healthcare provider in the network, but may require higher copays or coinsurance for out-of-network providers.
