If you’ve ever tried reading a health insurance policy, you probably noticed it’s filled with confusing words and technical terms. Words like deductible, copayment, coinsurance, and premium get thrown around — and if you don’t fully understand them, it’s easy to make the wrong choice when picking a plan.
Understanding the key health insurance terms can help you choose the right coverage, use your benefits wisely, and avoid unexpected bills. In this article, we’ll break down the most common health insurance terms in simple language so you can feel confident about your healthcare decisions.
1. Premium
Your premium is the amount you pay regularly (monthly, quarterly, or annually) to keep your health insurance active. Think of it as a subscription fee for your coverage.
You must pay your premium whether or not you use any medical services during the year.
💡 Example: If your premium is $150 per month, you’ll pay that amount every month just to keep your plan in effect.
2. Deductible
A deductible is the amount you pay out of your own pocket before your insurance starts covering your medical bills.
Once you meet your deductible, your insurer begins to share the costs with you (through copayments or coinsurance).
🏥 Example: If your deductible is $1,000, you’ll have to pay that much toward covered medical expenses before your insurance starts paying.
3. Copayment (Copay)
A copayment, or copay, is a fixed amount you pay each time you use a healthcare service, such as visiting a doctor or getting a prescription.
💊 Example: You might pay a $20 copay for a doctor’s visit, while your insurance covers the rest.
Copays often vary depending on the type of service — specialist visits usually cost more than regular checkups.
4. Coinsurance
After you meet your deductible, you’ll typically share a percentage of the cost with your insurer. This shared amount is called coinsurance.
💡 Example: If your plan covers 80% of medical costs, your coinsurance is 20%. That means for a $1,000 bill, you’ll pay $200, and your insurer will pay $800.
5. Out-of-Pocket Maximum (OOPM)
The out-of-pocket maximum is the most you’ll have to pay in a year for covered medical services (including deductibles, copays, and coinsurance).
Once you reach this limit, your insurance covers 100% of eligible expenses for the rest of the year.
⚖️ Example: If your OOPM is $5,000, and you’ve already paid that much during the year, your insurer will pay all remaining covered costs after that.
6. Network
Your insurance company has agreements with certain hospitals, doctors, and clinics — together, these are known as the network.
-
In-network providers have agreed to offer services at discounted rates.
-
Out-of-network providers may cost much more, and your insurance might cover less or nothing at all.
✅ Tip: Always check if a hospital or doctor is in-network before booking an appointment to avoid surprise bills.
7. Preauthorization (Prior Approval)
Some medical services or procedures require preauthorization (also called prior approval) from your insurance company before you receive them.
This means your doctor must get permission from your insurer to confirm that the treatment is medically necessary.
🩺 Example: MRI scans or surgeries often require preauthorization before your insurer agrees to pay.
8. Exclusions
Exclusions are medical services, treatments, or conditions that your insurance plan does not cover. These can vary depending on your policy.
Common exclusions include cosmetic surgery, dental care, or alternative treatments unless medically necessary.
⚠️ Tip: Always review your plan’s exclusions to avoid unexpected out-of-pocket expenses.
9. Pre-Existing Condition
A pre-existing condition is any health issue or illness you had before enrolling in your current insurance plan. Examples include asthma, diabetes, or heart disease.
Depending on your country and policy type, insurers may:
-
Cover these conditions immediately,
-
Impose a waiting period, or
-
Exclude them entirely.
💡 Example: Some plans might not cover diabetes-related expenses for the first 12 months after you join.
10. Waiting Period
The waiting period is the amount of time you must wait after buying your policy before certain benefits start.
During this time, your insurer may not cover specific treatments, especially for pre-existing conditions or maternity care.
🕒 Example: A health plan may have a 2-year waiting period for maternity coverage.
11. Claim
A claim is a formal request you or your healthcare provider submit to your insurance company for payment of medical services.
There are two main types:
-
Cashless claim: The insurer pays the hospital directly (available only at network hospitals).
-
Reimbursement claim: You pay first, then get reimbursed by your insurer after submitting bills and documents.
12. Sum Insured / Coverage Limit
The sum insured (or coverage limit) is the maximum amount your insurance will pay in a year for covered expenses.
💰 Example: If your sum insured is $10,000 and your total hospital bills reach $12,000, you’ll have to pay the extra $2,000 yourself.
13. Lifetime Limit
Some insurance policies have a lifetime limit, which is the total amount your insurer will pay over the lifetime of your policy. Once you reach that cap, you’ll have to cover all further expenses out of pocket.
⚠️ Not all plans have this limit, but it’s important to check.
14. Cashless Hospitalization
Cashless hospitalization allows you to get treated at network hospitals without paying upfront. Your insurer settles the bill directly with the hospital.
🏥 Example: If you’re admitted to a partner hospital, just show your health card — no need to pay cash during discharge.
15. Grace Period
If you miss your premium payment, the grace period is the extra time (usually 15–30 days) your insurer gives you to make the payment and keep your policy active.
Failing to pay within this period can result in your policy being canceled.

-
Choose a plan that fits your budget,
-
Avoid surprise medical bills, and

Being informed empowers you to take control of your health coverage and get the most value out of your insurance.
