What Is the Right Time to Buy Health Insurance? A Practical Guide for Kolkata and Bangalore Families

When should you buy health insurance?
As early as you can, and before you have a reason to. Health insurance works on a simple trade: the insurer takes on the risk while you are healthy, and in return you accept waiting periods and a premium. Buy after a diagnosis and the terms get harder. Buy early and most of the waiting periods are behind you by the time you need to claim.
Why earlier is usually better
Waiting periods start on the day you buy. Most policies won't pay for certain conditions until a period has passed. IRDAI caps the waiting period for pre-existing diseases at 36 months, and the same limit applies to specific illnesses such as joint replacement. A policy bought at 30 has its waiting periods finished long before you need major care. One bought at 55, when a condition has already appeared, starts the clock late.
The moratorium also builds up over time. After five years of continuous cover, an insurer cannot reject a claim on grounds of non-disclosure or misrepresentation, except in cases of proven fraud. Continuous years count, so buying early matters here too.
Premiums rise with age, and health can change. Insurers price by age and can increase premiums after underwriting if they find a health condition. Buying while healthy usually means a lower price and fewer questions.
Medical costs go up. A cover amount that felt generous a decade ago may be small today. Buying early lets you build up cover gradually instead of trying to catch up at once.
A few common moments to buy
Your first job. If you are healthy and your employer's group cover is your only insurance, add your own policy. Group cover usually ends when you change jobs or retire.
Marriage or a new baby. More people to protect, and a family floater or higher cover starts to make sense.
Buying a home or taking a loan. A large hospital bill in the same period can put your finances under real strain.
Turning 40. Health conditions become more likely, and waiting periods are best served before they appear.
Parents getting older. Consider a separate policy for them, or look at senior citizen plans.
Can you buy later in life?
Yes. IRDAI removed the maximum entry age for buying health insurance, and insurers cannot refuse a policy simply because someone has a pre-existing condition. But you will likely pay more, face medical check-ups and wait longer for cover on the conditions you already have. It is still better than having no policy at all.
Two cost points that make now a reasonable time
GST is now zero on individual policies. Since 22 September 2025, all individual health insurance policies, including family floater plans, are exempt from GST, which used to be 18%. This applies to premiums paid on or after that date, for both new policies and renewals. It does not cover group policies.
Section 80D can lower your tax. Health insurance premiums can be claimed as a deduction under Section 80D, but only under the old tax regime, and within set limits. Check which regime suits you before counting this as a saving.
What if you already have government cover?
If you have Swasthya Sathi or Ayushman Bharat PM-JAY, that gives up to ₹5 lakh per family per year, shared by the whole family. It is a good base, but a serious surgery can use most of it. A private policy sits above it. Narayana Aditi is one option in Kolkata, with a surgical limit of up to ₹1 crore at Narayana Health network hospitals. It is sold in specific districts and is mostly cashless at Narayana hospitals, so check that it matches where you live and which doctors you use.
When it makes sense to hold off
Waiting is rarely better, but a few situations call for care:
If you are choosing between plans, take a few days to compare rather than buying in a hurry.
If you hold an existing policy, don't drop it to switch. Use portability, which lets you carry over the credit for waiting periods already served.
If you haven't disclosed a health condition, disclose it. A claim can be challenged for non-disclosure until the five-year moratorium passes.
Before you buy
Read the Customer Information Sheet and policy wording.
Check the waiting periods for pre-existing and specific diseases.
Confirm the cashless network near you.
Answer every medical question on the proposal form honestly.
Use the 30-day free-look period after purchase to review the policy. If you disagree with the terms, you can return it.
Quick answers
What is the best age to buy health insurance? The earlier the better, ideally while you are young and healthy. There is no single ideal age, because it depends on your health, your responsibilities and any group cover you already have.
Is it too late at 50 or 60? No. There is no maximum entry age any more. Expect a higher premium and possibly a medical check-up.
Do I need my own policy if my employer covers me? Usually yes. Group cover generally ends when you leave the job, and you may lose your accumulated benefits.
Does the GST exemption apply to my renewal? Yes, if you pay on or after 22 September 2025 for an individual policy.
