Health Insurance Portability in India 2026: The Full Process, Every Deadline, and Why Insurers Say No

By Nitish Bharadwaj · Published Sep 20, 2026 · 6 min

Health insurance portability lets you move to a new insurer without restarting waiting periods, your moratorium clock, or accumulated no-claim bonus — but IRDAI only protects the switch if you apply inside a strict 45-to-60-day window before renewal and then pass the new insurer's own underwriting review. This guide walks through the complete process step by step, exactly what transfers automatically versus what resets, the specific underwriting and disclosure reasons insurers reject port applications, and what to do next if yours is turned down.

IRDAI has let policyholders switch health insurers without losing their waiting-period credit since 2011, yet most people still treat portability as a nuclear option they'll never actually use. The bigger issue is that even those who try it get tripped up — not because the rules are unclear, but because portability is really two separate systems stacked on top of each other: a rigid calendar you have to hit exactly, and an underwriting decision the new insurer is still free to make on its own terms. Understanding both halves is what decides whether you switch cleanly or end up stuck between two insurers, with neither one honouring a claim.

What the Portability Right Actually Covers

Portability, under IRDAI's health insurance rules, is the right to move your existing individual or family floater policy to a different insurer at renewal without being treated as a brand-new applicant for the purpose of waiting periods you've already served. That includes credit for time already served against your pre-existing disease (PED) waiting period, your progress toward the 5-year moratorium, and your accumulated no-claim bonus. What it does not do is force the new insurer to accept you — portability guarantees continuity of terms if you're accepted, not automatic acceptance itself.

The Complete Process, Step by Step

The process runs on two clocks moving in parallel — one that IRDAI fixes, and one the new insurer controls entirely on its own. You submit the portability proposal form directly to your chosen new insurer, never to your existing one, and only within a defined window before your current policy's renewal date. Here's exactly what happens after you submit, and which deadline belongs to which party.

What Actually Transfers, and What Starts Fresh

Time already served against your PED waiting period, your progress toward the moratorium, and your no-claim bonus all carry over at your existing sum insured — none of it restarts just because the insurer's name on your card has changed. What doesn't carry over automatically is any enhancement: if you use the port to also raise your sum insured, only the additional cover attracts a fresh waiting period, while your original amount keeps full continuity.

Why Insurers Actually Reject Port Applications

IRDAI's rules stop your existing insurer from blocking a port, but they don't stop the new insurer from applying its own underwriting judgment to your specific case — portability preserves continuity of terms, not a guaranteed approval. In practice, rejections cluster around a handful of recurring reasons, and knowing them before you apply is the difference between a clean switch and a wasted attempt during a window you can't easily repeat.

What to Do If Your Application Is Rejected

A rejection must come with a written reason under IRDAI rules — an insurer can't simply decline without stating grounds you can act on. If the reason is procedural, such as a missed disclosure or an incomplete field, you can usually correct it and reapply with the same or a different insurer in a future window, provided you keep your existing policy renewed and continuous in the meantime. If you believe the rejection is unjustified — for instance, the new insurer trying to impose a fresh waiting period on cover you'd already earned continuity on — escalate first through the insurer's own grievance cell, then to the IRDAI Bima Bharosa portal if it isn't resolved. Through any dispute, renewing your existing policy on time matters more than winning the argument quickly, since a lapse resets the very continuity you're trying to protect.

A Practical Checklist Before You Apply

• Confirm your renewal date and count backward to mark the 60-to-45-day application window on your calendar
• Request your claims history summary from your existing insurer in advance, so you know exactly what the new insurer will see
• Disclose every diagnosis made since your original policy started, even ones that feel minor — non-disclosure is the single most common ground for rejection or a later claim repudiation
• Keep the requested sum insured at or below your current level for the cleanest continuity; treat any increase as a separate underwriting decision with its own waiting period
• Never let your existing policy lapse while a portability decision is pending — renew it on time regardless of where the new application stands

Portability is a genuine right, not a formality insurers grant reluctantly — but it only works if you treat the calendar and the underwriting review as two separate things to get right, not one.
