Why does my new insurer ask for old records after porting?

They need to verify if your medical history matches your application to rule out any hidden pre-existing conditions.

What is the 5-year moratorium rule in health insurance?

After five years of continuous coverage, an insurer cannot reject your claim for non-disclosure, except in cases of proven fraud.

Does my No Claim Bonus transfer when I port?

Yes, your earned No Claim Bonus transfers to the new insurer, usually increasing your sum insured without extra cost.

How long does cashless approval take under new rules?

IRDAI now requires insurers to provide a decision on cashless requests within one hour of receiving the application.

What happens if I forget to mention a minor illness while porting?

It can lead to claim delays or rejection if the insurer discovers the omission during their investigation of your first claim.

Can I port my policy 10 days before expiry?

No, you should ideally initiate the porting process at least 45 days before your current policy expires to avoid coverage gaps.

The first claim tension

You just moved your health insurance to a better brand. You feel smart. You probably saved some money or got a higher sum insured for the same price. Then, four months later, you find yourself at a hospital in Hyderabad for a gallbladder surgery. You hand over your new card, expecting a smooth cashless experience. Instead, the hospital desk tells you the insurer is asking for your last five years of medical records. They are digging deep. It feels like they don't trust you. You are right. They don't. Not yet.

The fear of selection against the company

Insurers are naturally suspicious of early claims. If you port your policy in January and file a claim in April, their internal alarms go off. They call this selection against the company. It is a fancy way of saying they suspect you switched because you knew a surgery was coming. They think you chose them specifically to pay for an upcoming bill. To clear this doubt, they investigate. They want to verify if the medical history you mentioned on your porting form matches your actual health records.

The IIB portal is watching

Your new insurer has a secret weapon. It is the Insurance Information Bureau or IIB portal. This is a centralized database where every claim you have ever made is recorded. If you told your new insurer you had zero claims in the last three years, but the IIB portal shows a hospital stay in 2022, your claim is in trouble. They will look for any gap between what you said and what the data shows. This is why being honest about even minor things matters. Mentioning a small issue like chronic acidity or a one-day fever check-up might seem annoying, but it proves you aren't hiding anything.

The five-year moratorium rule

There is a light at the end of the tunnel. It is called the moratorium period. According to IRDAI, after you complete five years of continuous coverage with an insurer, they cannot reject your claim based on non-disclosure. They can only reject it if they prove fraud. But until you hit that five-year mark with your new provider, you are in the high-scrutiny zone. During these initial years, every single document matters. If you are porting, keep your old policy copies and every single discharge summary from the past. You will need them to prove your continuity benefits. If you lose these, your new insurer might treat you like a brand-new customer, making you wait 2 to 4 years for pre-existing disease coverage.

Continuity is not a blanket cover

Many people make a mistake here. They think if they port a 5L policy to a 10L policy, the entire 10L is covered immediately. That is not how it works. Your continuity benefits only apply to the original 5L. The extra 5L is treated as a fresh policy. It will have its own waiting periods. If you have a claim for ₹7 lakh in the first year, the insurer might approve ₹5 lakh under the ported rules but scrutinize the remaining ₹2 lakh under new policy rules. This often leads to partial claim approvals which can be frustrating if you aren't prepared for it.

The 1-hour cashless rule

Recent IRDAI guidelines have tried to make things easier for you. Insurers are now required to give a decision on your cashless request within one hour. This does not mean they will approve it in an hour. It means they must tell you if it is approved, rejected, or if they need more documents. This prevents you from sitting in the hospital lobby for an entire day. However, for ported policies, they often use this hour to ask for more documents rather than giving an instant green light. Being proactive helps. A medical check-up during the porting process acts as solid evidence of your health. It makes it much harder for the insurer to claim you had a pre-existing condition later.

Don't let agents skip the paperwork

Sometimes, an agent might tell you that porting is too much work. They might suggest just taking a new policy instead. Never do this. If you take a new policy, you lose every single benefit you earned over the years. You lose the credit for your waiting periods. You lose your No Claim Bonus. Always insist on the proper porting form. You must start this process at least 45 days before your current policy expires. This window is vital to ensure your data moves correctly from the old insurer to the new one. At OneAssure, we often see that clear documentation is the only thing that stands between a rejected claim and a smooth approval. It is better to be over-prepared with your paperwork than to be under-insured during a crisis.With the recent removal of GST on health insurance, the cost of protection has dropped. It is a great time to find a better plan. Just remember that the first year after a switch is a trial period. Keep your files ready. Be honest about your health. The scrutiny will eventually fade, and you will have the solid protection you paid for.
