Before you compare policies or look at premiums, you need to understand what health insurance actually is. This article is not about why you should buy it. It is a simple, clear orientation so that every term you encounter later in this series makes sense.
What Is Health Insurance?
Health insurance is a contract between you and an insurance company. You pay a regular amount called the premium. In return, the company agrees to pay for specified medical expenses if you or a covered family member falls ill or needs hospital treatment, subject to the terms of the policy.
It is designed to protect your savings from large, unexpected medical bills. The insurance company pools premiums from many people and uses that pool to pay the claims of those who need treatment.
How Health Insurance Works — High Level
You choose a plan and pay the premium (yearly or in instalments). The policy mentions a maximum amount the insurer will pay in a year — this is called the Sum Insured.
When you need treatment at a hospital that is part of the insurer’s network, the hospital can often settle the bill directly with the insurer (cashless). If you go to a non-network hospital, you pay first and then claim reimbursement from the insurer by submitting documents.
Health insurance is offered by both public-sector and private insurance companies in India, and also by specialised health insurers. The regulator is the Insurance Regulatory and Development Authority of India (IRDAI).
Did You Know?
Medical inflation in India has been averaging approximately 13–14% annually. At this rate, the cost of the same treatment can potentially double in about 5–6 years. Understanding this backdrop helps you appreciate why the structure of a health insurance policy matters.
Key Terms Explained in Simple Language
Sum Insured
The maximum amount the insurer will pay for claims in a policy year. Example: A ₹10 lakh sum insured means the insurer’s liability is capped at ₹10 lakh for that year (unless restoration applies).
Premium
The amount you pay to keep the policy active. It depends on age, sum insured, location, medical history and the features you choose.
Individual vs Family Floater
An individual plan covers only one person. A family floater covers the entire family under one sum insured. In a floater, the total cover is shared among all members.
Cashless vs Reimbursement
Cashless: The hospital settles the eligible bill directly with the insurer. You pay only non-payable items.
Reimbursement: You pay the hospital first and later submit bills to the insurer for repayment of eligible expenses.
Network Hospitals
Hospitals that have an agreement with the insurer. Cashless treatment is usually available only at these hospitals.
Waiting Period
The time you must wait after buying the policy before certain treatments or pre-existing conditions are covered. Initial waiting periods of 30 days for illness and longer periods (often 2–3 years) for specific conditions are common.
Pre-existing Disease (PED)
Any illness or condition you already had before buying the policy. Most policies cover PEDs only after a waiting period.
Room Rent Limit
Some policies restrict the daily room charges they will pay. Exceeding the limit can reduce the entire claim proportionately.
Co-payment
A percentage of the claim that you must pay yourself. Example: 10% co-pay means you pay 10% of the approved claim amount and the insurer pays the rest.
Deductible
An amount you agree to pay out of pocket before the insurer starts paying. Higher deductibles usually lower the premium.
Sub-limits
Internal caps on specific expenses (for example, cataract surgery or specific implants) even if the overall sum insured is higher.
Day-care Procedures
Treatments that do not require 24-hour hospitalisation (for example, cataract, dialysis, chemotherapy). Modern policies usually cover them.
Restoration Benefit
If the sum insured is fully used in a year, some policies restore it (fully or partially) for subsequent claims in the same year, usually for unrelated illnesses.
No Claim Bonus (NCB)
A reward for not making a claim. The sum insured increases by a certain percentage each claim-free year, or the premium may reduce, depending on the policy.
Exclusions
Conditions or treatments the policy will not cover (for example, cosmetic surgery, self-inflicted injuries, certain dental treatments, or expenses during the waiting period).
Claim Settlement
The process of getting the insurer to pay a valid claim. It involves intimating the insurer, submitting documents, and receiving the payment (cashless or reimbursement).
