Understanding health insurance can be challenging, particularly because of the industry-specific terms that frequently appear in policies and explanations. Familiarity with these terms is essential to making informed decisions about coverage, selecting the right plan, and managing healthcare expenses effectively. Health insurance involves a unique language that describes the details of coverage, payment structures, and how benefits are accessed, making it important for policyholders to know key terms to navigate the healthcare system confidently.

This guide will clarify common health insurance terms to provide a foundational understanding for those new to insurance or looking to deepen their knowledge. From understanding deductibles and premiums to knowing the difference between co-pays and coinsurance, each term in this guide is explained in straightforward language to empower you as a consumer. Whether you’re selecting a new plan or simply trying to better manage your healthcare expenses, knowing these terms will enable you to make choices that align with your health and financial goals.

Key Health Insurance Terms to Know

1. Premium
   The premium is the amount you pay regularly (usually monthly) to maintain your health insurance coverage. It’s like a subscription fee to access health insurance benefits. Premiums are paid regardless of whether you use healthcare services. Higher premiums often correspond to plans with lower deductibles, while lower-premium plans may come with higher out-of-pocket costs.
2. Deductible
   A deductible is the amount you must pay out-of-pocket for healthcare services before your insurance begins to cover the costs. For example, if you have a $1,000 deductible, you’ll pay for healthcare services yourself until you’ve spent $1,000. After reaching the deductible, your insurance starts to share the costs according to the policy terms.
3. Co-pay
   Co-pay, or co-payment, is a fixed amount you pay for specific services, such as doctor visits or prescriptions, at the time of service. For instance, a plan may have a $30 co-pay for each doctor’s visit. Co-pays do not usually count toward your deductible but do count toward your out-of-pocket maximum.
4. Coinsurance
   Coinsurance is the percentage of costs you share with your insurer after meeting your deductible. For example, if your plan has 20% coinsurance, you pay 20% of the cost of covered services while the insurance pays the remaining 80%. Coinsurance continues until you reach your out-of-pocket maximum.
5. Out-of-Pocket Maximum
   The out-of-pocket maximum is the most you’ll have to pay for covered healthcare services in a year. Once this limit is reached, your insurance covers 100% of eligible healthcare costs for the remainder of the year. This maximum includes deductibles, co-pays, and coinsurance but does not include premiums.
6. Network
   A network consists of doctors, hospitals, and other healthcare providers that have agreements with an insurance company to provide services at discounted rates. In-network providers generally cost less for policyholders, while out-of-network providers may lead to higher costs or no coverage, depending on the plan.
7. In-Network vs. Out-of-Network
   In-network providers are part of your insurance plan’s network, offering services at lower costs. Out-of-network providers are not contracted with your insurer, often resulting in higher charges or no coverage. Some plans, like HMOs, only cover in-network care, while others, like PPOs, offer some coverage for out-of-network care at a higher cost.
8. Formulary
   A formulary is a list of prescription drugs covered by your insurance plan. Formularies are typically divided into “tiers” that determine the cost of the medication. For instance, generic drugs may be in a low-cost tier, while brand-name drugs or specialty medications are in higher-cost tiers.
9. Explanation of Benefits (EOB)
   An Explanation of Benefits, or EOB, is a document your insurance provider sends after you receive care. The EOB outlines what services were covered, the total cost of care, any discounts, and what you owe. It is not a bill but rather a summary of the claim process for your records.
10. Claim
    A claim is a request for payment that your healthcare provider submits to your insurance company on your behalf. The insurance company reviews the claim to determine what portion of the charges are covered under your plan.
11. Preventive Care
    Preventive care refers to services aimed at preventing illness, such as vaccines, screenings, and wellness visits. Under many health plans, including those compliant with the Affordable Care Act (ACA), preventive care is covered at no cost when provided by in-network providers.
12. HMO (Health Maintenance Organization)
    An HMO plan requires members to use a primary care physician (PCP) and get referrals to see specialists. HMO plans typically only cover in-network providers except in emergencies. These plans often have lower premiums and out-of-pocket costs but less flexibility in provider choice.
13. PPO (Preferred Provider Organization)
    PPO plans offer more flexibility, allowing members to see any provider without a referral, though they pay less for in-network providers. While PPOs typically have higher premiums than HMOs, they appeal to those who want broader provider options.
14. EPO (Exclusive Provider Organization)
    EPO plans are a middle ground between HMO and PPO plans, covering in-network services only but without requiring referrals. EPOs often provide lower premiums and out-of-pocket costs but restrict members to a specific network of providers.
15. POS (Point of Service)
    POS plans combine elements of HMO and PPO plans. Members must choose a primary care physician and get referrals for specialists but have the option to use out-of-network providers at a higher cost.
16. Prior Authorization
    Prior authorization is the process of getting approval from your insurance company before receiving certain treatments or medications. This step ensures that the procedure or medication is medically necessary and eligible for coverage.
17. Balance Billing
    Balance billing occurs when an out-of-network provider charges you for the difference between their rate and the amount your insurer covers. Some plans, like HMOs, do not cover out-of-network providers at all, leaving you responsible for the full amount if balance billing occurs.
18. High-Deductible Health Plan (HDHP)
    A high-deductible health plan (HDHP) has a higher deductible than traditional plans but often comes with lower monthly premiums. HDHPs are typically paired with Health Savings Accounts (HSAs) and appeal to those who want lower premiums and can manage higher out-of-pocket costs if needed.
19. Health Savings Account (HSA)
    An HSA is a tax-advantaged savings account used to pay for qualified medical expenses. HSAs are available only to individuals with HDHPs and allow account holders to save pre-tax income for healthcare expenses, with unused funds rolling over annually.
20. Flexible Spending Account (FSA)
    An FSA is a pre-tax savings account for medical expenses, offered by employers. Unlike HSAs, FSAs do not require enrollment in an HDHP, but any unused funds often expire at the end of the year.
