Staying with an insurer purely because switching feels risky is one of the most common, and most avoidable, mistakes health insurance buyers make in India. Portability exists precisely to remove that risk, letting you move to a better insurer, a lower premium, or a wider hospital network without losing the waiting period progress and continuity benefits you have already earned. This guide explains exactly how portability works, what carries forward, and how to time the switch correctly.

Many policyholders assume that switching insurers means starting from zero. As though the years already spent serving waiting periods and building toward the moratorium simply evaporate. That assumption keeps people locked into policies that no longer serve them well, sometimes for a decade or more. Once you understand exactly what portability protects and what it does not, the decision to switch becomes a straightforward cost-benefit comparison rather than a leap of faith.

What is Health Insurance Portability?

Portability is the IRDAI-mandated right of every individual health insurance policyholder, including family floater cover, to switch from one insurer to another, or from one plan to a different plan within the same insurer, without losing the continuity benefits already earned under the existing policy. Introduced specifically to prevent policyholders from feeling trapped with an underperforming insurer, portability applies to the waiting periods you have already served, most importantly the pre-existing disease waiting period and progress toward the five-year moratorium period, provided the switch happens without any break in coverage.

It is worth being clear about what portability is not. It is not a mid-term switch you can invoke whenever you like; it can only happen at the point of renewal. It is also not a guaranteed acceptance; the new insurer still conducts fresh underwriting and can accept, modify or decline your application based on your disclosed health and claims history. What portability guarantees is narrower but genuinely valuable: if you are accepted, the time you have already spent under waiting periods is not wasted. 

Portability vs. migration: it's worth knowing these are not the same thing, even though people use "port" loosely for both. Portability means switching to a different insurance company. Migration means switching to a different plan within your same insurer. Migration is generally faster and involves lighter underwriting, but it only gives you access to that one insurer's product range; portability opens the whole market but comes with the fuller underwriting scrutiny described below.

Why Port Your Policy?

• Better coverage: a newer plan from the same or a different insurer may offer a wider network, a restoration benefit, or a shorter waiting period than your current policy provides.
• Lower premium: premiums vary meaningfully between insurers for comparable cover, and a fresh comparison at renewal time can surface genuine savings.
• Service issues: a pattern of slow claim settlement, unresponsive customer service, or a shrinking network hospital list is a legitimate reason to move, and portability exists specifically so you are not stuck with a poor experience purely to preserve your waiting period progress.

• Sum insured or feature gaps: if your current policy lacks a feature you now need, such as maternity cover or a wider critical illness rider, porting to a plan that includes it may be more efficient than buying an entirely separate policy.

   

When Portability May Not Be the Right Move

Portability is a tool, not a default. In a few situations, staying put is the safer call. Close to the five-year moratorium: if you are in your fourth or fifth year with your current insurer, you are near the point where the insurer can no longer contest a claim over non-disclosure, except in cases of proven fraud. Porting resets none of that credit, but it does trigger a fresh round of underwriting scrutiny, so if your past disclosures were anything less than complete, moving now can invite a level of review you would rather avoid this close to the finish line.

Recently diagnosed with a serious condition: if you have just been diagnosed with a critical illness, the new insurer's underwriting will almost certainly flag it, and you risk a permanent exclusion or outright rejection. Your existing insurer is already contractually bound to cover you under your current terms; that protection is worth more than any premium saving right now.

A treatment or surgery is already scheduled: applying for portability while a hospitalisation is imminent is one of the fastest ways to get an application declined. Wait until treatment is complete before starting the process.

Your current insurer is actually performing well: if claims have settled smoothly and the network has covered what you needed, porting for a marginally lower premium or a slightly better feature rarely justifies restarting the underwriting relationship from scratch.

How Portability Works: Complete Process

• Shortlist a new insurer and plan, comparing sum insured, waiting periods, network hospitals and premium against your current policy. Two numbers are worth checking specifically: the claim settlement ratio (aim for above 90%, since it reflects how often claims are paid without a fight) and the incurred claim ratio (a healthy range is roughly 60–80%, indicating the insurer is priced sustainably rather than either overcharging or under-provisioning). Both are published in IRDAI's annual handbook on Indian insurance statistics.
• Submit a portability request to the new insurer, along with a completed proposal form and full, honest disclosure of your medical history, at least 45 days before your current policy's renewal date.
• The new insurer sends a data request to your existing insurer through the Insurance Information Bureau, and the existing insurer is required to share your policy and claims history within a set timeframe.
• The new insurer reviews your application and claims history, and within 15 days of receiving complete information, must communicate acceptance, a modified offer, or rejection. If no response is given within this window, the request is deemed accepted under IRDAI rules.

• If accepted, pay the premium for the new policy before your existing policy's renewal date. The new policy then begins the day after your old policy would have expired, with your continuity benefits carried forward.

   

What Happens to Your Waiting Period?

This is the single most valuable protection portability offers. Both figures are current: the pre-existing disease waiting period cap was cut from 48 months to 36 months, and the moratorium period was shortened from 8 years to 5 years, under IRDAI's Insurance Products Regulations and the May 2024 Master Circular on Health Insurance Business. Anything you read online that references a 4-year PED wait or an 8-year moratorium, is describing the pre-2024 rule.

The new insurer must give you credit for the time already served under your previous policy toward the pre-existing disease waiting period, currently capped at a maximum of 36 months, and toward progress on the five-year moratorium period. If you have completed 24 months of a 36-month pre-existing disease waiting period with your old insurer, porting means you only need to serve the remaining 12 months with the new insurer, rather than starting the full 36 months over again.

This is worth restating with a concrete number attached, since it is easy to underestimate how much value this protection carries. Consider a policyholder who ported after 30 months into a 36-month pre-existing disease waiting period. If they later let their policy lapse and had to buy fresh cover from scratch, those 30 months would be lost entirely, and they would restart at zero. Portability, done correctly without a coverage gap, is what stands between years of progress and starting over.

This credit applies specifically to your original sum insured. If you increase your sum insured at the time of porting, the additional amount above your previous cover is treated as a fresh policy for waiting period purposes, and may carry its own new waiting period. The portion equal to your old sum insured, however, retains full continuity. Your accumulated no claim bonus, converted into an equivalent addition to sum insured under most insurers' current practice, also typically transfers, though the exact treatment can vary, so confirm this specifically with the new insurer before finalising the switch.

Documents Required for Portability

• Your existing policy document and the most recent renewal receipt.
• A completed proposal form for the new insurer, with full and honest disclosure of medical history.
• Claim history from your previous policy, if available, since the new insurer will independently request this, but having it on hand speeds up the process.
• Identity and address proof for every member being ported.

• Any recent medical reports relevant to disclosed conditions, particularly useful if you want the new insurer to assess a well-controlled condition favourably.

   

Portability Timeline: When to Apply

IRDAI requires the portability request to be submitted to the new insurer at least 45 days before your current policy's renewal date. Applying earlier than this, though not mandatory, gives more comfortable buffer time for underwriting, particularly if the new insurer requests medical tests or additional documentation. Applying too close to the renewal date risks running out of time for the process to complete, which could leave you needing to renew your existing policy for continuity while the portability request is still pending, or in the worst case, facing a coverage gap if the timing is mismanaged.

A useful practical rule is to mark a reminder 60 days before your renewal date each year, giving yourself a two-week window to compare alternatives before the 45-day application deadline, rather than making the decision under time pressure.

Common Rejection Reasons for Portability Requests

• Break in coverage: if your existing policy lapsed at any point, even briefly, the continuity benefit that portability protects is already lost, and the new insurer has no obligation to treat the application as a genuine port.
• Incomplete or inaccurate disclosure: the new insurer conducts fresh underwriting based on your proposal form, and gaps or inaccuracies here can lead to rejection or a modified, less favourable offer.
• Applying too late: requests submitted well within the 45-day window leave insufficient time for the data exchange and underwriting process to complete before renewal.
• Adverse claims history: a pattern of frequent or high-value claims can lead a new insurer to decline the application or offer modified terms, since portability guarantees waiting period credit, not automatic acceptance.
• Mismatch in policy category: porting is generally permitted only between similar policy categories, such as individual to individual or family floater to family floater, not across fundamentally different product types.

Portability is one of the most underused tools available to Indian health insurance policyholders, and using it well simply requires planning ahead of your renewal date rather than treating your current insurer as a permanent choice. Review your policy annually, compare it honestly against what else is available, and apply for portability in good time if a switch genuinely serves you better. The same annual review habit is worth extending to your term insurance and to your car insurance and two-wheeler insurance, since better terms are often available simply by comparing rather than auto-renewing.

Conclusion

Health insurance portability removes the biggest reason people stay with an underperforming insurer, the fear of losing years of waiting period progress. Understanding the 45-day timeline, the documents needed, and exactly what carries forward turns portability from an intimidating process into a routine annual check, no different from comparing rates before renewing any other policy. Use it deliberately, and your health cover can keep improving over time instead of simply renewing on autopilot.

FAQs

Q. How do I port my health insurance policy to another company?

Shortlist a new insurer, submit a portability request with full medical disclosure at least 45 days before your current renewal date, and pay the new premium once accepted, before your old policy expires.

Q. Does portability retain waiting period benefits?

Yes, the new insurer must give credit for waiting periods already served under your old policy, up to your existing sum insured, provided there was no break in coverage.

Q. What documents are needed for health insurance portability?

Your existing policy document, a completed proposal form with medical disclosures, identity proof, and ideally your claim history and recent medical reports if relevant.

Q. Can I port my policy if I increase my sum insured?

Yes, but the additional sum insured above your previous cover may carry a fresh waiting period, while the original amount retains full continuity.

Q. When should I apply for health insurance portability?

At least 45 days before your current policy's renewal date, with earlier applications giving more comfortable buffer time for underwriting and documentation.

Q. Can a portability request be rejected?

Yes, common reasons include a break in coverage, incomplete disclosure, applying too late, or an adverse claims history that leads the new insurer to decline or modify the offer.

Q. Does my no claim bonus carry forward when I port?

Most insurers carry forward the equivalent sum insured addition from an accumulated no claim bonus, though the exact treatment can vary, so confirm this with the new insurer.

Q. Can group health insurance be ported?

A group policy itself cannot be ported as a group. An individual member leaving or retiring from a group scheme has to go through two steps: first migrate to an individual or family floater policy with the same insurer (usually without fresh underwriting if done within the insurer's specified window), and only after that can the policy be ported to a different insurer under standard portability rules. Moving directly from a group scheme to a different insurer is not permitted.

Q. Is there a fee to port a health insurance policy?

No, portability itself is free of charge, though you will pay the premium for your new policy just as you would for any regular renewal.
