A hospital stay of even a few days can cost anywhere from a few thousand rupees to several lakhs, depending on the treatment and the hospital. Health insurance is designed to help you pay eligible medical bills so a single medical emergency doesn’t drain your savings. In simple terms, it’s a contract where you pay a premium to an insurer, and in return, the insurer agrees to pay for eligible medical expenses, subject to the terms of your policy.
That’s the basic idea. But “how much” the insurer pays, and under what conditions, is where most beginners get confused. This article explains what health insurance is, how it works, what it covers, key policy terms, claim types, costs, tax benefits, and what to check before buying a policy.
What Is Health Insurance?
A health insurance policy is an agreement between you and an insurance company. You pay a premium to keep the policy active. In exchange, the insurer agrees to pay for eligible medical expenses up to a limit called the sum insured, as long as the treatment and the circumstances fall within the policy’s terms.
- You pay: the premium to keep the policy active.
- The insurer pays: eligible medical expenses, up to your sum insured, based on the policy’s terms and conditions.
- You may still pay: certain amounts yourself, such as deductibles, co-payments, or expenses the policy excludes.
For example, if you have a ₹10 lakh health insurance cover and you’re hospitalised for an eligible treatment costing ₹3 lakh, the insurer may pay the covered amount according to the policy terms, while you may still have to pay applicable deductibles, co-payments, or any expenses that fall outside what the policy covers.
This is an important point for beginners: ₹10 lakh coverage does not mean every ₹3 lakh hospital bill gets paid in full. How much actually gets settled depends on the specific policy you hold.
How Does Health Insurance Work?
1. You buy a policy
You choose a sum insured (how much cover you want) and pay the premium for it. The premium generally depends on your age, health condition, city, family size, and the features of the plan.
2. The policy becomes active
Once you pay the premium, the policy is in force. But it doesn’t mean everything is covered from day one. Most policies have waiting periods, set stretches of time during which certain treatments or pre-existing conditions aren’t covered. These periods vary by insurer and by plan, so it’s worth checking your specific policy document.
3. You receive medical treatment
If you need hospitalisation or treatment, it needs to fall within what your policy covers for the insurer to consider paying. Not every treatment or condition is automatically included.
4. You make a claim
There are two broad ways to claim:
- Cashless claim: The hospital bills the insurer (or the insurer’s TPA, third-party administrator) directly for eligible expenses, so you don’t have to pay large amounts upfront. This is usually available only at the insurer’s network hospitals.
- Reimbursement claim: You pay the hospital bill yourself first, then submit the bills and documents to the insurer to get eligible expenses reimbursed.
5. The insurer settles the eligible claim
The insurer reviews your claim against the policy’s terms, checking things like whether the treatment is covered, whether any waiting period applies, and whether the documentation is complete, before settling the eligible amount. Settlement timelines and requirements can differ across insurers.
What Does Health Insurance Cover?
Depending on the policy, health insurance may cover:
- Hospitalisation expenses, subject to the minimum hospitalisation period or conditions specified in the policy
- Pre-hospitalisation expenses, costs incurred in the days before admission, such as tests and consultations
- Post-hospitalisation expenses, follow-up costs after discharge, such as medicines and check-ups
- Day-care procedures, treatments that don’t need a full day of hospitalisation due to advances in medical technology (like cataract surgery)
- Ambulance expenses, subject to a limit
- Certain diagnostic tests, if covered under the plan
- Specific treatments, such as certain therapies or surgeries, if included in the policy
None of these are guaranteed across every policy. Whether a particular expense is covered depends on the plan you buy, so it’s worth reading the policy document rather than assuming.
What Does Health Insurance Not Cover?
This is one of the most important things for a first-time buyer to understand. Every policy has exclusions: situations or treatments the insurer will not pay for.
Depending on the policy, common exclusions may include:
- Certain pre-existing conditions, during the applicable waiting period
- Cosmetic procedures, unless they’re medically necessary
- Non-medical expenses, such as certain hospital administrative charges
- Treatments the policy specifically excludes in its wording
- Certain conditions or procedures that fall within a waiting period
There’s no single, universal exclusion list that applies to every policy. Insurers word their exclusions differently, so the only reliable way to know what’s excluded in your case is to read the exclusions section of your specific policy document before buying.
To make this concrete, here are a few situations where a claim could be reduced or denied, depending on the policy:
- You’re hospitalised for a condition that falls within the policy’s waiting period for pre-existing diseases.
- You undergo a cosmetic procedure that isn’t medically necessary, and the policy excludes it.
- You claim for an expense such as a specific medicine, consumable, or treatment that the policy wording lists as excluded.
These are illustrations of how exclusions play out in practice, not an exhaustive list. Your own policy document will spell out exactly what applies to you.
Important Health Insurance Terms You Should Know
| Term | Simple Meaning |
| Sum insured | Maximum coverage available under the policy |
| Premium | Amount paid for the insurance policy |
| Deductible | Amount you may have to pay before the insurer pays, depending on the policy |
| Co-pay | Percentage of an eligible claim that you agree to pay |
| Waiting period | Period during which certain conditions/treatments may not be covered |
| Network hospital | Hospital that has an arrangement with the insurer/TPA for cashless treatment |
| Cashless claim | Eligible treatment settled directly between insurer and network hospital, subject to policy terms |
| Reimbursement claim | You pay the hospital and later claim eligible expenses from the insurer |
| Room rent limit | Restriction on the room category/amount covered under some policies |
| No-claim bonus | Benefit offered by some policies for claim-free periods |
What Is the Difference Between Cashless and Reimbursement?
Cashless: The insurer (through its network) settles eligible expenses directly with the hospital, so you don’t need to arrange a large sum upfront. This is only available at hospitals within the insurer’s network, and it still requires approval; the insurer checks the claim against your policy terms before authorising payment.
Reimbursement: You pay the hospital bill yourself, then submit the bills, discharge summary, and other required documents to the insurer, who reimburses the eligible amount afterward.
One thing worth remembering: cashless does not mean “free treatment.” It only means you’re not paying the hospital directly at the time of treatment. You may still be liable for deductibles, co-pay, room-rent differences, or any non-covered items, depending on your policy.
How Much Health Insurance Cover Do You Need?
There’s no single number that works for everyone. The right sum insured depends on factors like:
- Your age and the age of family members covered
- Family size
- City of residence (treatment costs are typically higher in metros)
- Existing medical conditions or family medical history
- Any health cover you already have, such as through an employer
- Your income and how much of a financial shock you can absorb
- General hospital costs in your area for common treatments
As an illustrative example only: a young, healthy individual living in a smaller city with no dependents may find a smaller cover adequate for now, while a family of four living in a metro, with ageing parents to cover, may need a substantially larger sum insured. A ₹5 lakh policy may not be sufficient for every family, particularly where hospitalisation costs are high. These are illustrations, not rules; your own number should come from your own situation.
Individual vs Family Floater
Individual health insurance: Each family member has their own, separate sum insured. If you buy ₹10 lakh individual cover each for yourself and your spouse, you each have ₹10 lakh available independently.
Family floater: One sum insured is shared across all the family members covered under the policy. So a ₹10 lakh family floater for a family of four means the ₹10 lakh is a common pool; if one member uses ₹6 lakh in a year, only ₹4 lakh remains available for the rest of the family for that year.
Neither option is always better; it depends on your family’s health profile, ages, and budget. A family floater may be more cost-efficient for some younger, healthier families, while individual policies may make more sense when family members have significantly different health needs.
Health Insurance vs Mediclaim
You’ll often hear people use “mediclaim” and “health insurance” interchangeably. Mediclaim was historically used to describe basic hospitalisation insurance policies in India, and the term has stuck around in everyday conversation.
In practice, today’s health insurance policies can vary widely in what they cover, from basic hospitalisation to broader plans that include OPD, day-care, wellness benefits, and more. So while “mediclaim” is often used casually to mean health insurance, it’s worth checking exactly what a specific policy includes rather than assuming based on the name.
What Should You Check Before Buying Health Insurance?
- Sum insured: is it realistic for your family’s needs and city?
- Premium: is it affordable for you to pay every year, including as you age?
- Waiting periods: how long before pre-existing conditions or specific treatments are covered?
- Pre-existing disease conditions: how are they defined and treated under this policy?
- Exclusions: what exactly is not covered?
- Room-rent limits: is there a cap on the room category, and what happens if you choose a higher category?
- Co-pay: what percentage, if any, will you need to pay on eligible claims?
- Deductibles: is there a fixed amount you pay before the insurer’s cover kicks in?
- Network hospitals: are hospitals near you and hospitals you’d prefer to use included?
- Claim process: how straightforward is it for both cashless and reimbursement?
- Restoration or recharge benefits: does the sum insured refill if exhausted during the year, if offered?
- No-claim bonus: does the cover increase for years without a claim?
- Renewal terms: can the policy be renewed easily, and up to what age?
- Sub-limits: are there caps on specific treatments (like caps on cataract surgery cost)?
- Policy wording: have you actually read the fine print, not just the brochure?
These matter because two policies with the same sum insured can behave very differently at claim time. A cheaper policy can sometimes leave you paying more at claim time if it has a high co-pay, room-rent limit, or other restrictions.
How to Choose a Health Insurance Policy
Step 1: Estimate your likely healthcare needs, based on your age, family, and any known health conditions.
Step 2: Decide how much coverage you realistically need, factoring in where you live and your family size.
Step 3: Compare exclusions and waiting periods across the plans you’re considering.
Step 4: Check which hospitals are in the network, especially the ones near your home or the ones you’d actually want to use.
Step 5: Compare co-pays, deductibles, and sub-limits, since these affect how much you’ll actually pay at claim time.
Step 6: Read the policy wording carefully before you purchase, not just the brochure or the sales pitch.
Tax Benefits
Health insurance premiums can qualify for a deduction under Section 80D of the Income Tax Act, but only if you’re filing under the old tax regime; this deduction is not available if you opt for the new tax regime. For FY 2025-26, the deduction is generally up to ₹25,000 for premiums paid for yourself, your spouse, and dependent children, rising to ₹50,000 if any of those insured is aged 60 or above.
A separate deduction of up to ₹25,000 (or ₹50,000 if a parent is aged 60 or above) is available for premiums paid for parents, taking the maximum possible deduction up to ₹1 lakh in a year if both you and your parents qualify for the senior citizen limit. A sub-limit of up to ₹5,000 for preventive health check-ups is included within these overall limits, not in addition to them.
Tax rules do change from time to time, and eligibility depends on which regime you file under and the specific conditions that apply to you, so it’s worth checking the latest rules on the Income Tax Department’s website or with a tax professional before you file. Either way, the tax deduction should be seen as a secondary benefit; the main reason to buy health insurance is financial protection against medical costs, not the tax savings.
Common Health Insurance Mistakes
- Buying only based on the lowest premium, without checking what’s actually covered.d
- Ignoring the exclusions section of the policy
- Not checking waiting periods before assuming a condition is covered
- Choosing inadequate coverage that doesn’t match real hospitalisation costs in your city
- Not checking the hospital network, especially hospitals near you
- Not understanding co-pay and being surprised by it at claim time
- Hiding or under-reporting medical information while buying the policy, which can lead to claim rejection later
- Assuming cashless means every expense is covered, when deductibles or sub-limits may still apply
- Not reading renewal terms, including how premiums may change as you age
Who Should Have Health Insurance?
Health insurance can be relevant for a wide range of people: young working professionals just starting, families planning for their children and ageing parents, self-employed individuals who don’t have any employer cover, and anyone without access to employer-provided health insurance.
Even if your employer already provides health cover, it’s worth checking what that cover actually includes. Employer-provided health insurance may not always be enough; it often has a limited sum insured, may not extend to all family members, and typically stops the moment you leave the job. So before buying another policy, check what your employer’s cover already provides and where it falls short.
Final Verdict
Health insurance isn’t simply about buying the biggest possible cover or the cheapest premium you can find. What actually matters is whether the policy gives you useful financial protection for your specific healthcare needs, and whether you understand what it covers, what it excludes, its waiting periods, co-pays, deductibles, claim process, and coverage amount before you’re ever in a position where you need to use it.
Read the policy wording, ask questions where something isn’t clear, and choose a plan that fits your real situation rather than the one with the flashiest brochure.
