Demystifying Health Insurance Terminology: 15 Key Terms You Need to Know


Health insurance is an essential aspect of personal finance and well-being, providing crucial coverage for medical expenses and ensuring access to quality healthcare services. However, understanding health insurance terminology can be overwhelming, as it involves numerous technical terms and concepts. In this article, we will demystify 15 key health insurance terms, helping you gain a better understanding of how health insurance works and empowering you to make informed decisions about your coverage.


1. Premium


The premium is the amount you pay to the insurance company regularly (e.g., monthly, quarterly, annually) to maintain your health insurance coverage. It is a fixed cost that you must pay regardless of whether you use medical services during that period.


2. Deductible


The deductible is a predetermined amount you pay for covered medical services before your insurance company covers expenses. For instance, if your deductible is $1,000, you are responsible for paying the first $1,000 of eligible medical expenses before insurance coverage kicks in.


3. Co-payment (Co-pay)


A co-payment is a fixed amount you pay at the time of receiving medical services, such as doctor visits or prescription medications. For example, if you have a $20 copayment for a doctor's visit, you will pay $20 when you see the doctor, and the insurance company will cover the rest of the cost.



4. Co-insurance


Coinsurance is the percentage of medical expenses you are responsible for after meeting your deductible. For example, if your coinsurance is 20%, you will pay 20% of covered medical expenses, and your insurance company will cover the remaining 80%.


5. Out-of-Pocket Maximum


The out-of-pocket maximum represents the highest amount you'll pay for covered medical services within a policy period. Once you reach this limit, your insurance company will cover 100% of eligible expenses for the remainder of the period.



6. Network


The network refers to a group of healthcare providers, hospitals, and medical facilities that have contracted with an insurance company to provide services to policyholders. In-network providers have negotiated rates with the insurance company, resulting in lower costs for policyholders.


7. Out-of-Network


Out-of-network refers to healthcare providers and services that are not part of your insurance plan's network. Using out-of-network providers may result in higher costs, and some services may not be covered at all.



8. Health Maintenance Organization (HMO)


HMO is a type of managed care plan that requires members to choose a primary care physician (PCP) from a network of providers. The PCP acts as the central point of contact for all healthcare needs and referrals to specialists. In HMOs, services outside the network are typically not covered, except for emergency situations.


9. Preferred Provider Organization (PPO)


PPO is another type of managed care plan that offers more flexibility in choosing healthcare providers without needing referrals. PPOs cover both in-network and out-of-network services, although out-of-network services often come with higher costs.


10. Exclusive Provider Organization (EPO)


EPO is similar to a PPO in that it provides coverage for in-network services only. However, EPOs do not cover any out-of-network services, except in emergencies.


11. Point of Service (POS)


POS plans combine features of HMOs and PPOs. Like HMOs, POS plans require members to choose a primary care physician and obtain referrals for specialists. However, like PPOs, POS plans offer some coverage for out-of-network services.



12. Health Savings Account (HSA)


An HSA is a tax-advantaged savings account that allows individuals to save money specifically for medical expenses. HSAs are typically paired with High Deductible Health Plans (HDHPs), and the funds contributed to an HSA are not subject to federal income tax at the time of deposit.


13. Formulary


A formulary is the list of prescription drugs that are covered by your health insurance plan. Drugs on the formulary are typically grouped into tiers, with different copayments or coinsurance for each tier.


14. Pre-authorization 


Pre-authorization involves obtaining approval from your insurance company before receiving specific medical services or treatments. Some procedures, tests, or medications may require preauthorization to ensure they are medically necessary and covered by your plan.


15. Pre-Existing Condition


A pre-existing condition is a health condition that existed before you applied for health insurance coverage. Prior to the Affordable Care Act (ACA), insurance companies could deny coverage or charge higher premiums for individuals with preexisting conditions. However, the ACA prohibits insurance companies from denying coverage or charging more based on preexisting conditions.


Final Thought


Understanding health insurance terminology is crucial for making informed coverage decisions. Key terms like premium, deductible, copayment, coinsurance, network, and out-of-pocket maximum help grasp health insurance workings and find a suitable plan for your healthcare needs.


Take time to review each health insurance plan, including provider networks, coverage options, and benefits. Seek guidance from licensed agents or financial advisors if needed to choose the right plan for you and your family.



Health insurance is an investment in well-being and financial security, safeguarding against unexpected medical expenses and granting access to quality healthcare. With a clear understanding of health insurance terms, confidently navigate the healthcare world for a better quality of life.
