Porting health insurance: what you keep, what you lose, and the trap in the new policy

You switch health insurers for a lower premium and a better claim-settlement ratio. You port the policy, so your pre-existing-disease waiting carries over and nothing restarts. Two years later you are admitted, and the new insurer pays less than your old one would have. Nothing went wrong with the port. The new policy simply had a room-rent cap your old one didn't, and you never checked.

Porting is one of the most useful rights you have as a policyholder, and one of the most misunderstood. It moves your history to a new insurer. It does not bend the new insurer's terms to suit you. Get the first part, miss the second, and a switch that looked like an upgrade quietly becomes a downgrade. Here is how portability actually works.

What porting is, in one line

Portability lets you move to a new health insurer at renewal without serving your waiting periods again. It is a right granted under IRDAI's health insurance regulations, and it applies both between insurers and between plans of the same insurer.

The point of it is simple. Waiting periods, the months or years before pre-existing diseases and specific illnesses are covered, are the biggest thing locking you into a policy. Without portability, switching would mean starting that clock from zero. With it, the time you have already served travels with you.

What actually transfers

What you keep	What you don't
Served waiting periods (pre-existing disease, specific-illness, initial 30-day)	Waiting-period credit on any increase in sum insured
Credit up to your existing sum insured	The old policy's room rent, co-pay and sub-limits
Accrued cumulative bonus, per the new plan's rules	Your old premium (the new plan's pricing applies)

The line that matters: credit is tied to your existing sum insured. If you had ₹5 lakh cover and port into a ₹10 lakh plan, your served waiting periods usually apply to the first ₹5 lakh. The extra ₹5 lakh can carry fresh waiting. Worth confirming before you assume the whole new cover is seasoned.

The timing rules people miss

Porting only happens at renewal, and it runs on a clock:

• Apply at least 45 days before your renewal date. Later than that and the insurer can decline to process it in time.
• Not earlier than 60 days before, either.
• The new insurer pulls your claim and policy history through the Insurance Information Bureau, underwrites the request, and accepts or declines.
• If they sit on it past the window IRDAI allows, the request can be deemed accepted. That protection only helps if you applied early, so don't leave it to the last week.

Miss the window and you are not porting this year. You renew as you are, or you switch and start every waiting period over. Neither is what you wanted.

The trap: portability protects your history, not the new policy's terms

This is where people lose money. Porting carries your waiting-period credit. It does not carry your old policy's structure. The moment you switch, you live under the new plan's rules, and those can be quietly worse:

• Room rent: your old plan may have had no cap; the new one may limit you to 1% of sum insured a day, which drags down every linked charge at claim time.
• Co-pay: the new plan may make you pay 10% or 20% of each claim out of your own pocket.
• Sub-limits: caps on specific procedures like cataract or knee replacement that your old policy didn't impose.

A lower premium and a shinier claim-settlement ratio can sit right on top of a policy that pays you less. The claim ratio tells you how often an insurer pays something. It says nothing about the caps that decide how much.

How to port without a nasty surprise

A short checklist before you switch:

1. Start 45 to 60 days before renewal. Fill the portability form and proposal with the new insurer.
2. Match the sum insured you want seasoned. If you are raising cover, ask in writing how waiting periods apply to the increase.
3. Confirm how your bonus carries over. Cumulative bonus usually rides along, but on the new plan's terms.
4. Read the new policy's caps, not just its price. Room rent, co-pay, disease-wise sub-limits. This is the step that actually protects your payout.
5. Keep the old policy active until the port is confirmed. Don't let it lapse and leave a gap in cover.

Step 4 is the one people skip, and it is the one that costs. Rather than compare policies line by line yourself, FinDecode reads the new policy against IRDAI rules and flags the room rent, co-pay, sub-limits and waiting periods, every figure taken from the document itself.

FAQ

Can I port my health insurance any time? No. Portability is allowed only at renewal. Apply to the new insurer at least 45 days before your policy renews, and not earlier than 60 days before.

Do I lose my waiting periods when I switch insurers? Not if you port. The waiting periods you have already served, for pre-existing diseases and specific illnesses, are credited by the new insurer up to your existing sum insured.

Does porting cost anything? There is no separate charge for porting. You pay the new policy's premium, which may be higher or lower depending on the plan and your age.

Does my no-claim bonus transfer? Accrued cumulative bonus can carry over, usually added to your sum insured, subject to the new plan's rules. Confirm how the new insurer applies it before you switch.

What if the new insurer doesn't respond in time? IRDAI rules require the new insurer to act on a porting request within a set window. If they delay beyond it, the request can be treated as accepted. Applying early is what makes that protection useful.

FinDecode provides AI-assisted analysis to help you understand your policy. It is not legal or financial advice. Portability, the crediting of served waiting periods up to the existing sum insured, and the application window before renewal are set out in IRDAI's health insurance regulations, published on irdai.gov.in. The exact treatment of a sum-insured increase and of cumulative bonus depends on your new plan's wording, so confirm both with the new insurer in writing.
