What actually carries over
Portability lets you move to a different insurer's health policy while retaining credit for the time you have already served.
The reason it matters: a health policy's real value is not the sum insured, it is the waiting periods you have already served. A policy held for six years with every waiting period behind it is a far better asset than an identical new policy, and without portability switching would mean surrendering that entirely.
Broadly, accumulated waiting-period credit carries across — including the credit built towards pre-existing disease coverage. Accrued no-claim or cumulative bonus is also generally portable. The specifics of what ports and in what form are set by regulation and have been revised, so confirm the current position before relying on it.
What does not carry is the new policy's own terms. You are moving to a different product, with different exclusions, sub-limits and definitions — and those apply from day one.
Why people stay put anyway
Three reasons, and only one of them is good.
The belief that waiting periods restart. Wrong, and it is the most common reason. It keeps people in policies with poor service, unfavourable sub-limits or a network that no longer suits them.
The process seems daunting. It is paperwork and a timing window rather than anything difficult, but it does have to be initiated deliberately.
The new insurer may decline or load the premium. This is the legitimate concern. Portability is not a right to be accepted — the new insurer underwrites you afresh, and if your health has changed since the original policy was issued, the offer may be worse or absent. Which means the time to port is while you are healthy, not after a diagnosis, and that is precisely when nobody bothers.
When it is worth doing
- Sub-limits that will bite. Particularly a room rent cap, which reprices an entire bill through proportionate deduction. Moving to a policy without one is among the strongest reasons to switch.
- A weak hospital network where you live, which decides whether cashless is available at all.
- Poor claim experience — slow settlement, unexplained deductions, difficulty reaching anyone.
- A materially better product at comparable cost. Health products have changed considerably, and a policy bought a decade ago may have terms no longer competitive.
- Moving from a group policy to an individual one before leaving a job — see below, because this is the most valuable case.
Not worth doing for a marginally lower premium. The premium difference is small against the risk of a worse underwriting outcome, and price is the least important thing about a health policy.
The case that matters most: leaving a job
The single highest-value use of portability, and the one with a deadline.
Employer group cover generally ends with the employment — the gap set out in losing an income. Many group policies allow conversion to an individual policy from the same insurer, and doing so may preserve the continuity you accumulated under the group cover.
The window is short and it is easy to miss while dealing with everything else a job change involves. Missing it means buying a fresh individual policy with new waiting periods, at an older age, with any condition acquired in the meantime now pre-existing.
This should be on the first-week list when leaving any job, ahead of almost every other financial task. The exact conditions vary by insurer and by policy — confirm them with the insurer directly rather than assuming.
The process
- Start well before renewal. Regulation sets a window in which the application must be made ahead of the renewal date. Miss it and you wait another year.
- Apply to the new insurer with the portability form and your existing policy details.
- Disclose everything. The new insurer underwrites afresh, and non-disclosure here has the same consequence as on any proposal — it is the largest controllable cause of a rejected claim.
- The new insurer responds within a stated timeline, accepting, declining, or offering with a loading or specific exclusion.
- Do not cancel the old policy until the new one is confirmed in force. A gap between the two is a period with no cover and can break continuity.
- Get the credited waiting periods in writing on the new policy document, and check them rather than assuming.
Point five is the one that causes real harm. Cancelling early to save a premium leaves a window uninsured, and if the new application is then declined you are left with nothing.
Before you switch
Compare the new policy on the things that actually decide claims, not on premium.
| Check | Why |
|---|---|
| Room rent capping | Triggers proportionate deduction across the whole bill |
| Sub-limits by procedure | Caps inside the sum insured that are easy to miss |
| Exclusions list | Different product, different exclusions, from day one |
| Network hospitals near you | Decides whether cashless is available in practice |
| Restore benefit conditions | Often excludes the same illness for the same member |
| Credited waiting periods | Confirm in writing on the new document |
Also worth knowing: if you increase the sum insured on porting, the increase may be treated as fresh cover with its own waiting period, even where the original amount ports cleanly. Verify how the insurer treats it.
What continuity is worth
The reason all of this matters is narrow and large: an uninsured or partly-insured medical event is funded by selling long-term assets, usually at a bad moment.
That cost is measurable. FNOTrader's Mutual Funds app reports maximum drawdown alongside returns across the full AMFI NAV history — around 34 million NAV rows — and the gap between a plan held to term and one liquidated mid-drawdown is what continuous cover protects.
FNOTrader does not sell insurance and does not recommend policies or insurers. Portability rules are set by IRDAI and change — verify the current position before acting.
Common questions
Do I lose my waiting periods if I change health insurer?
No — that is precisely what portability prevents. Accumulated waiting-period credit, including credit built towards pre-existing disease coverage, generally carries across, as does accrued no-claim bonus. The specifics are set by regulation and have been revised.
Can the new insurer refuse me?
Yes. Portability is not a right to be accepted — the new insurer underwrites you afresh and may decline, load the premium, or impose specific exclusions. That is why the time to port is while you are healthy rather than after a diagnosis.
When should I apply to port?
Well before your renewal date, since regulation sets a window in which the application must be made. Missing it means waiting another year.
What is the most valuable use of portability?
Converting employer group cover to an individual policy before leaving a job, which may preserve the continuity accumulated under the group policy. The window is short and easy to miss, and missing it means new waiting periods at an older age.
Should I cancel my old policy once I apply?
No. Do not cancel until the new policy is confirmed in force. A gap leaves you uninsured and can break continuity, and if the new application is declined you would be left with nothing.
Is a lower premium a good reason to switch?
Rarely. The premium difference is small against the risk of a worse underwriting outcome, and price is the least important thing about a health policy. Sub-limits, exclusions and network coverage decide claims.
Does an increased sum insured port too?
Not necessarily. An increase on porting may be treated as fresh cover with its own waiting period even where the original amount ports cleanly — confirm how the insurer treats it before assuming.
