You don’t need to be a health insurance expert! But health insurance is something you’ll deal with for a long time.
If your parents have been taking care of your doctor visits and paying for insurance, this might be the first time you handle it yourself.
The more you know, the better. Let’s go over the basics so you can understand how health insurance works.
What is Health Insurance?
This might seem basic, but it’s important to start here—especially if you’re used to a healthcare system where the government covers medical costs.
Health insurance is a type of policy that helps pay for medical expenses. Some plans cover general healthcare, like doctor visits and hospital stays. Others focus on specific needs, like vision or dental care.
Most people think of health insurance as a plan that helps pay for doctor bills, surgery, and hospital costs.
It works like car or home insurance. You choose a health insurance plan and pay a set amount, called a premium. In return, the insurance company pays part of your medical bills for certain services.
Not everything is covered. Some medical services are not included in health insurance plans. These are called exclusions and limitations, and they are listed in the policy.
How Does Health Insurance Work?
When you buy a health insurance plan, you become a member of that plan. You are part of a group called a risk pool. This pool includes both healthy people and those with ongoing health issues.
Some people in the group need more medical care. They are considered high-risk. Others don’t visit the doctor as often. They are low-risk.
Insurance companies look at everyone in the pool and figure out how much money is needed to cover medical costs. Everyone pays a premium, and that money helps cover medical expenses for the group.
In return for your premium, the insurance company helps pay for covered medical services. Your policy lists these services and what you need to pay, like a co-pay, deductible, or coinsurance.
If medical costs in the pool get too high for a long time, the insurance company might raise premiums to cover expenses.
What are the Types of Health Insurance Plans?
There are different kinds of health insurance plans. Here are the most common ones:
1. Health Maintenance Organization (HMO)
An HMO plan only covers care from doctors and hospitals that are part of its network. It usually won’t pay for care outside the network unless it’s an emergency or you get special approval.
To qualify for an HMO, you may need to live or work in a certain area. These plans focus on regular check-ups and prevention. You might also need a referral from your primary doctor to see a specialist.
2. Preferred Provider Organization (PPO)
A PPO plan gives you more freedom to see doctors both in and out of the network. You don’t need a referral to see a specialist.
If you go to an in-network doctor, you’ll pay less. If you see an out-of-network doctor, your costs will be higher.
PPO plans usually have higher monthly premiums because they offer more choices. Some PPOs also come with high deductibles, meaning you pay more upfront before insurance starts covering costs.
3. Exclusive Provider Organization (EPO)
EPO plans are a mix of HMO and PPO plans. Like an HMO, you can only use in-network doctors unless it’s an emergency. But, like a PPO, you don’t need a referral to see a specialist.
4. Point of Service (POS)
With a POS plan, you need to pick a primary care doctor (PCP) to manage your healthcare. If you need a specialist, your PCP will give you a referral.
You can see out-of-network doctors, but it will cost more than staying in-network.
| Plan Type | Network Restrictions | Referral Required for Specialist | Primary Care Physician (PCP) Required | Out-of-Network Coverage |
| HMO (Health Maintenance Organization) | Only in-network (except emergencies or special approval) | Yes | Yes | No (except emergencies) |
| PPO (Preferred Provider Organization) | Both in-network and out-of-network (higher cost for out-of-network) | No | No | Yes (at higher cost) |
| EPO (Exclusive Provider Organization) | Only in-network (except emergencies) | No | No | No (except emergencies) |
| POS (Point of Service) | Mostly in-network but allows out-of-network at higher cost | Yes | Yes | Yes (at higher cost) |
What are the Costs of Health Insurance?
When you have health insurance, you pay different types of costs. Here’s what they mean:
1. Premium
A premium is the amount you pay to have health insurance. You or your employer pay this amount every two weeks, every month, or once a year. You have to pay it whether you use medical services or not.
2. Cost Sharing
Cost sharing is what you pay out of pocket for medical care. It includes deductibles, copayments, and coinsurance. It does not include your premium, extra charges for out-of-network doctors, or services that your plan doesn’t cover.
Medicaid and the Children’s Health Insurance Program (CHIP) also include premiums as part of cost sharing.
3. Deductible
A deductible is the amount you must pay before your insurance starts covering costs.
For example, if your deductible is $1,000, you have to pay that amount first before your plan helps with covered medical bills. Some plans have separate deductibles for different services, like in-network and out-of-network care.
4. Copayment (Copay)
A copay is a set amount you pay for a covered medical service. For example, you might pay $20 for a doctor visit after meeting your deductible.
5. Coinsurance
Coinsurance is a percentage of the cost of a service that you must pay.
For example, if your coinsurance is 15%, you pay 15% of the bill for a prescription or medical procedure after meeting your deductible.
Can You See Any Doctor with a Health Insurance Plan?
Not always. Some health insurance plans require you to use certain doctors, hospitals, and pharmacies.
These are called in-network providers because they have contracts with the insurance company to offer services at lower rates.
In-Network Provider
An in-network provider has an agreement with your insurance plan. They charge a discounted rate for medical services. If you go to an in-network doctor, you’ll usually pay less. These providers are also called preferred providers or participating providers.
Out-of-Network Provider
An out-of-network provider does not have a contract with your insurance plan. If your plan covers out-of-network care, you’ll likely pay more for these services.
If your plan does not cover out-of-network care, you may have to pay the full cost, which can be a major burden during a medical emergency. These providers are also called non-preferred or non-participating providers.
