Porting your health policy: you keep the waiting periods you have already served

The most common reason people stay in a health policy that no longer fits them is a belief that switching means starting again from zero. It is worth saying plainly: it does not. Portability exists precisely to stop insurers holding customers hostage with accrued waiting periods, and it works.

What travels with you

When you port at renewal, the incoming insurer must credit you for time already served:

• The pre-existing disease waiting period. Three years into a three-year PED wait, you arrive at the new insurer with three years served, not zero.
• Specified illness waiting periods - the two-year list covering hernia, cataract, joint replacement and similar.
• The 30-day initial waiting period, long since exhausted on any policy old enough to be worth porting.
• The five-year moratorium clock. This is the quiet one. After five years of continuous cover an insurer cannot reject a claim for non-disclosure or misrepresentation, proven fraud aside. That clock does not restart on porting - it follows the continuity of your cover, not the name on the policy. Why it matters more than the PED rule is set out in the waiting period guide.

What does not

One thing starts fresh, and it is usually the reason people are porting in the first place: any increase in sum insured. The layer you already held carries its served waiting periods across. The increment is new cover, and the insurer may apply a fresh waiting period to that slice.

What that looks like in practice

Rekha is 46 and four years into a ₹5 lakh family floater with a 1% room rent cap. Base premium ₹14,200. She has served her full PED waiting period and is in year four of the five-year moratorium. She ports at renewal to a ₹10 lakh policy with no room rent cap, at a base premium of ₹21,400.

Position	Stays put	Ports to ₹10 lakh
Sum insured	₹5,00,000	₹10,00,000
Room rent cap	1%, or ₹5,000 a day	None
PED waiting on the first ₹5 lakh	Served	Served, carried over
PED waiting on the ₹5 lakh increment	Not applicable	Fresh, up to 3 years
Moratorium clock	Year 4 of 5	Year 4 of 5, continues
Base premium	₹14,200	₹21,400

If Rekha is admitted next year for a declared pre-existing condition, that claim is met up to ₹5 lakh - the ported layer - while the newer ₹5 lakh is not yet available for that particular condition. For everything else, the full ₹10 lakh is live immediately.

Now put a number on what she bought. On the old capped policy, a ₹2.6 lakh hospitalisation in a room costing ₹8,000 a night came back ₹97,500 short, because proportionate deduction scales down the entire bill and not just the room charge. That arithmetic is worked through in full in the room rent article. Rekha paid ₹7,200 a year to delete a ₹97,500 exposure and double her cover at the same time. That is the trade, and it is not close.

The window: 45 to 60 days before renewal

Portability is available only at renewal, and the application must reach the incoming insurer at least 45 days and not more than 60 days before the renewal date. Inside 45 days it will be refused as too late to process. Earlier than 60 and it will be refused as premature.

That window is not bureaucratic decoration. Inside it, the outgoing insurer has to hand over your policy and claims history through the industry data exchange, and the incoming insurer has to underwrite on that history. Missing it by a week means waiting an entire policy year.

What the new insurer is allowed to do

Portability protects your continuity. It does not oblige anyone to accept you.

• The incoming insurer can underwrite afresh. It may ask for a medical, and it will read your claims history.
• It can decline the proposal outright.
• It can apply a loading, or exclude a specific condition, on the new contract.
• It cannot reset a waiting period you have already served on the ported sum insured. That is the whole point of the mechanism and it is not negotiable.

Which produces one hard rule of sequencing: do not cancel anything, or let anything lapse, until the new policy is actually issued. Apply early in the window, keep the existing policy paid, and step across only once the replacement is in your hand.

The risk nobody worries about, which is the real one

Everything above concerns a fear that turns out to be largely unfounded. Meanwhile the thing that genuinely destroys continuity gets almost no attention: a lapsed renewal.

Health policies carry a grace period, commonly 30 days, within which a late renewal preserves continuity - though treatment taken during the gap itself is not covered. Past that, the policy is dead. Not paused. Whatever you buy next is a new contract: the PED waiting period begins again, the specified illness list begins again, and the five-year moratorium restarts at zero. Rekha, four years in, would be back at year one.

So the ranking is clear. Renewing on time is worth more than any add-on, any discount and any amount of shopping around. Set a reminder 75 days out - it gives you a fortnight to think, and lands you neatly at the top of the portability window if you decide to move.

A short checklist before you port

1. Pull your current schedule and note the sum insured, the room rent clause, any sub-limits, and how many years of each waiting period you have served.
2. Decide what you are actually buying. Usually it is removal of a room rent cap, a higher sum insured, or a better hospital network in your city.
3. Apply between 60 and 45 days before renewal.
4. Declare everything. The moratorium shields you only after five continuous years, and non-disclosure before that is still grounds for rejection.
5. Keep the old policy in force until the new one is issued.

If you would like someone to read your schedule and tell you whether porting is worth it in your case, that is the job on health insurance. We do it without a fee, and roughly half the time the honest answer is to stay where you are and simply raise the sum insured.
