Health insurance comes in several different structures, each with its own way of managing costs and how you receive care. Learning about these types helps you understand what options might work for your situation. The main types you will encounter include Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), Exclusive Provider Organizations (EPOs), and High Deductible Health Plans (HDHPs).

An HMO typically requires you to choose a primary care doctor who manages your healthcare. This doctor acts as a gatekeeper, meaning you usually need a referral from them to see a specialist. HMOs generally have lower monthly costs but more limited networks of doctors and hospitals. If you go to an out-of-network provider without authorization, you may pay the full cost yourself. According to the Kaiser Family Foundation, about 28% of people with employer health insurance are enrolled in HMO plans as of recent data.
PPO plans offer more flexibility than HMOs. You do not need a primary care doctor or referrals to see specialists. You can visit any doctor or hospital, though you will pay less if you use providers in the plan's network. Out-of-network care costs more, but it is still partially covered. This flexibility comes with higher monthly premiums and higher out-of-pocket costs when you use services.
EPO plans fall between HMOs and PPOs. They have network requirements like HMOs but do not require a primary care doctor or referrals. However, they typically do not cover out-of-network care at all, except in emergencies. High Deductible Health Plans pair lower monthly premiums with higher deductibles—the amount you pay before insurance starts sharing costs. These plans often work well for people who are generally healthy and do not use many medical services.
Practical takeaway: Write down the types of plans available to you through your employer or insurance marketplace. For each one, note the monthly cost, deductible, and whether your current doctors are in the network. This comparison will help you narrow down which structure fits your healthcare needs and budget.
To use your health insurance wisely, you need to understand the different ways you pay for care. These costs add up to your total healthcare spending, so knowing how they work prevents surprises when you receive medical bills. The main cost-sharing methods are deductibles, copays, and coinsurance, and each serves a different purpose in how insurance expenses are divided between you and your insurance company.

A deductible is the amount of money you must pay for covered healthcare services before your insurance plan starts to pay its share. For example, if your plan has a $1,500 deductible, you pay the first $1,500 of healthcare costs out of your own pocket. After you meet your deductible, your insurance company begins to share the costs with you. According to the Kaiser Family Foundation's 2023 data, the average deductible for individual coverage through an employer was $1,735, and for family coverage it was $3,715. Some services, like preventive care, may be covered without meeting the deductible first.
A copay is a fixed dollar amount you pay each time you use a covered service. For instance, you might pay $25 every time you visit your primary care doctor, $50 for an urgent care visit, or $150 to visit a specialist. Copays do not count toward your deductible—they are separate payments. This means even after you meet your deductible, you still pay a copay when you receive services. Prescription medications often have copays, which may be different amounts depending on whether the drug is generic or brand-name.
Coinsurance is a percentage of the cost of a service that you pay after you have met your deductible. For example, your plan might cover 80% of the cost of a procedure while you pay 20%. Unlike copays, coinsurance amounts vary based on the actual cost of the service. After you reach your out-of-pocket maximum—the most you will pay in a year—your insurance covers 100% of covered costs for the rest of that year.
Practical takeaway: Create a simple table with your plan's deductible, copay amounts for different types of care, coinsurance percentage, and out-of-pocket maximum. Keep this somewhere easy to reference, like a note on your phone, before you schedule medical appointments or procedures.
Most Americans—about 156 million people according to the Census Bureau—receive health insurance through their workplace. Employer-sponsored insurance is often the most affordable way to obtain coverage because employers typically pay a significant portion of the premium. Understanding what your employer offers and when you can make changes is important for managing your healthcare costs.

When you start a new job, you will usually receive information about health plan options during an onboarding period, sometimes called new-hire enrollment. This is your opportunity to choose a plan. The options your employer offers might include multiple versions of the plan types mentioned earlier, each with different cost levels. Some employers offer a high-cost plan with lower deductibles and more coverage, a mid-range plan, and a lower-cost plan with higher deductibles. You typically choose one during this initial enrollment window.
Once your coverage begins, you are generally locked into your choice until the next Open Enrollment Period, which usually happens once per year in the fall. During Open Enrollment—typically lasting about 30 days—you can change plans or add dependents. If you have a qualifying life event, such as getting married, having a child, losing other coverage, or moving to a new state, you may be able to make changes outside of Open Enrollment. Some employers also offer a Section 125 Cafeteria Plan, which lets you use pre-tax dollars to pay for premiums and out-of-pocket medical expenses through a Health Savings Account or Flexible Spending Account.
Your employer is required to provide you with a Summary of Benefits and Coverage (SBC), which is a standardized document showing exactly what your plan covers, what you pay, and what the plan does not cover. This document makes it easier to compare your employer's plan options side by side. You can also contact your company's benefits administrator or human resources department with specific questions about coverage, networks, or how to file claims.
Practical takeaway: Request copies of all available plan summaries and the Summary of Benefits and Coverage documents from your employer's benefits team. Compare them by looking at your current doctors and medications to see which plan would cost you the least for your specific healthcare needs.
If you do not have health insurance through an employer, you can purchase coverage directly through the Health Insurance Marketplace, also called the exchange. The Marketplace operates differently in each state—some states run their own Marketplace, while others use the federal Marketplace at Healthcare.gov, and some use a partnership model. The Marketplace was created as part of the Affordable Care Act and has provided coverage to millions of people since it began in 2014.

The Marketplace offers plans in four metal levels: Bronze, Silver, Gold, and Platinum. These names refer to how costs are shared between you and the insurance company. Bronze plans have the lowest monthly premiums but higher deductibles and out-of-pocket costs. Platinum plans have the highest monthly premiums but cover more of your costs when you receive care. Silver and Gold plans fall in between. Additionally, some people who have lower incomes may receive cost-sharing reductions that lower their deductibles and copays even further on Silver plans.
Many people who purchase Marketplace coverage through Healthcare.gov receive tax credits that reduce their monthly premium payments. These tax credits are based on your household income and family size. In 2023, the American Rescue Plan extended enhanced tax credits, making coverage more affordable for many people. For example, according to the Department of Health and Human Services, 90% of people choosing a plan at Healthcare.gov received tax credits that reduced their premium costs. Some people also qualify for cost-sharing reductions, which lower the deductibles and copays they pay out of pocket.
Open Enrollment for the Marketplace happens once per year, usually from November through January. During this period, you can sign up for coverage, change plans, or drop coverage. If you miss Open Enrollment and do not have a qualifying life event, you will have to wait until the next year to make changes. Special Enrollment Periods lasting about 60 days are available if you experience certain life
