Understanding Health Insurance Basics

Health insurance is a contractual agreement between an individual (or a group such as through an employer) and an insurance company. The insurance company agrees to provide financial protection by covering a portion of the insured’s medical expenses in exchange for regular premium payments. The primary goal of health insurance is to mitigate the financial burden associated with healthcare services making essential medical care more accessible and affordable.
Key Components of Health Insurance Coverage
- Premiums: These are monthly or annual payments made to the insurance company to maintain coverage. Premium amounts can vary based on factors such as age location and the type of plan selected.
- Deductibles: A deductible is the amount of money an individual must pay out-of-pocket before the insurance company begins to cover medical expenses. Higher deductibles typically result in lower monthly premiums while lower deductibles may mean higher premiums.
- Co-payments and Co-insurance: Co-payments are fixed amounts paid by the insured at the time of service (e.g. $20 for a doctor’s visit). Co-insurance refers to the percentage of costs shared between the insured and the insurance company after the deductible has been met (e.g. 80% coverage by the insurer 20% by the insured).
- Out-of-Pocket Maximum: This is the maximum amount an insured individual will have to pay for covered services in a given year. Once this limit is reached the insurance company typically covers all remaining costs for covered services.
- Network: Health insurance plans often have networks of preferred providers including doctors hospitals and clinics. In-network providers have negotiated rates with the insurance company resulting in lower out-of-pocket costs for the insured. Out-of-network providers may result in higher costs or may not be covered at all depending on the type of plan.

- Point of Service (POS)
- POS plans combine features of HMOs and PPOs.
- Individuals are required to choose a primary care physician and obtain referrals for specialist consultations.
- While these plans offer some flexibility in choosing providers costs may vary based on whether services are received in-network or out-of-network.
