After 60 Months, Your Health Insurer Cannot Contest Claims: The IRDAI Moratorium Period

Buried inside the IRDAI Master Circular on Health Insurance Business dated 29 May 2024 (document reference 4942918) is a clause that quietly rewrote the balance of power between Indian policyholders and their health insurers. After sixty continuous months of coverage, your insurer loses the right to contest a claim on any ground other than proven fraud. That is five years, not the eight years (96 months) that governed policies bought before the 2024 circular took effect. For a country where lakhs of hospitalisation claims are repudiated each year on the wording of a disclosure form filled in years earlier, the shrinking of that window by 36 months is one of the most consumer-friendly reforms IRDAI has issued in a decade.

This deep dive explains exactly what the 60-month moratorium is, when the clock starts, how enhancements to your sum insured reset it, and the traps that can still cost you a claim even after five years of premiums.

The Rule / Product

The moratorium period is defined in the IRDAI Master Circular on Health Insurance Business (Ref: IRDAI/HLT/CIR/MISC/2024, dated 29 May 2024). It states that after the completion of sixty continuous months of coverage under a health insurance policy, no claim shall be contestable except for proven fraud. The moratorium applies to the sum insured that was in force during those sixty months, and once the period is complete the policy becomes incontestable on grounds of non-disclosure or misrepresentation of a pre-existing disease.

Before 29 May 2024, the moratorium under IRDAI's 2020 health regulations was eight years (96 months). The 2024 Master Circular reduced it to sixty months, a change that applies prospectively and is now the default across all indemnity health products, whether individual or family floater. The table below sets out the shift.

The legal logic mirrors, but is not identical to, Section 45 of the Insurance Act 1938, which bars a life insurer from questioning a policy after three years of commencement (see the bare Act on indiacode.nic.in). Health insurance sits outside Section 45's three-year rule, which is precisely why IRDAI had to write a separate moratorium into its health regulations. The 2024 circular is the operative source; you can read it directly on the regulator's portal at irdai.gov.in.

Two conditions must both hold for the moratorium to complete. First, coverage must be continuous — a lapse that is not restored within the grace period can break the count. Second, the sixty months are counted from the date the policy (or the specific sum insured) was first put in force, not from the date any single illness was diagnosed.

Why It Matters

Health claim repudiation in India overwhelmingly turns on the "non-disclosure" argument. An insurer that receives a hospitalisation bill can, in the first years of a policy, investigate whether the insured failed to declare a condition at the proposal stage. The moratorium removes that weapon after sixty months: once the clock runs out, the insurer cannot reopen the proposal form to argue you concealed diabetes, hypertension or any other condition. The only surviving ground is fraud that the insurer can prove — a far higher bar than mere non-disclosure.

Consider the practical consequence for someone who bought a Rs 10 lakh floater in 2020. Under the old 96-month rule that policyholder would have waited until 2028 for incontestability. A person buying the same cover on 1 June 2024 reaches incontestability on 1 June 2029 — five years, saving three full years of exposure to the non-disclosure defence. For older buyers who purchase cover in their fifties, shaving three years off the contestable window materially improves the odds that a claim in their sixties is honoured.

There is also a subtle shift in where the burden of proof sits. During the first sixty months the insurer that alleges non-disclosure carries the onus of showing the condition existed and was not declared, but it may reopen the proposal form to do so. Once the sixty months complete, that door is shut entirely: the insurer must instead establish deliberate fraud, a standard the Supreme Court of India has repeatedly held requires evidence of intent, not mere silence. For the policyholder that is a move from a defensible position to an almost unassailable one, and it happens automatically on the sixty-first month without any paperwork on your part.

The reform also rewards early and continuous buying. Because the clock only runs while coverage stays live, a policyholder who lets a policy lapse and re-buys resets to month zero. That interacts directly with portability: when you port from Insurer A to Insurer B, IRDAI rules require the accrued moratorium and waiting period credit to carry over, so a clean port does not restart your five-year count. Before you switch insurers, model the premium difference on our health insurance premium calculator and confirm in writing that your moratorium credit transfers.

Worked Numbers

Take Meera, aged 45, who buys an individual health policy on 1 July 2024 with a base sum insured of Rs 15 lakh. She pays an annual premium of Rs 22,000. Three years later, on 1 July 2027, she enhances her cover to Rs 25 lakh because medical inflation has eroded the real value of Rs 15 lakh. Here is how the moratorium clock runs on each layer of her cover.

This split is the single most misunderstood part of the rule. The 2024 circular is explicit: where the sum insured is enhanced, the completion of sixty continuous months applies from the date of enhancement, but only on the enhanced limits. Meera's original Rs 15 lakh becomes incontestable on 1 July 2029. The extra Rs 10 lakh she added in 2027 only becomes incontestable on 1 July 2032. If she is hospitalised in August 2029 for a claim of Rs 20 lakh, the first Rs 15 lakh sits inside the completed moratorium while the balance Rs 5 lakh — drawn from the enhanced layer — is still contestable on non-disclosure grounds.

Now put a premium figure on it. Across the five-year base moratorium Meera pays roughly Rs 22,000 x 5 = Rs 1,10,000 (ignoring annual repricing) to reach incontestability on her original Rs 15 lakh. The cumulative bonus she accrues for claim-free years adds sum insured at no extra premium, but note that a bonus-linked increase is generally treated as an accretion to the existing cover rather than a fresh enhancement, so it does not usually start a new sixty-month clock — a point worth confirming with your insurer in writing. To compare the term-versus-health premium trade-off across your family's cover, our term insurance premium calculator sets out the parallel life-cover maths.

Pitfalls

The moratorium is powerful, but it does not neutralise the structural limits written into your policy schedule. Five years of continuous premiums cannot rescue a claim that fails on a sub-limit or a co-pay, because those are contractual caps, not contestability defences. Watch these traps.

1. Sub-limits survive the moratorium. If your policy caps cataract surgery at Rs 40,000 or knee replacement at Rs 1.5 lakh, that sub-limit applies whether you are in year one or year seven. The moratorium stops the insurer contesting whether to pay; it does not lift the ceiling on how much it pays. Read your schedule of benefits for every disease-wise cap.

2. Room-rent caps trigger proportionate deduction. A policy with a 1% of sum insured room-rent limit on a Rs 5 lakh cover restricts your room to Rs 5,000 a day. Choose a Rs 10,000 room and the insurer applies room-rent capping proportionately across the entire bill, often slashing a settled claim by 40-50%. The moratorium offers no protection here.

3. Co-payment is a fixed share, always. A 20% co-payment clause means you fund one-fifth of every admissible claim for the life of the policy. On a Rs 8 lakh hospitalisation that is Rs 1.6 lakh out of your pocket, in year six exactly as in year one.

4. Proven fraud is the escape hatch that remains. The circular preserves the insurer's right to repudiate for fraud even after sixty months. Fraud requires deliberate deception the insurer can evidence — fabricated bills, staged admissions, or knowingly false declarations — which is a much higher standard than the ordinary "you didn't disclose" argument. Honest non-disclosure is protected after five years; dishonest misrepresentation is not.

5. Continuity is fragile. Miss a renewal beyond the grace period and the policy lapses; the moratorium count can restart from zero on a fresh policy. Set renewal auto-debit and treat the grace period as an emergency buffer, not a plan.

6. Enhancements quietly reset part of the clock. As Meera's example showed, every top-up to the sum insured starts a fresh sixty-month count on the added layer. This is not a reason to avoid enhancing — medical inflation makes higher cover essential — but you should know that the enhanced portion is contestable for five more years.

FAQ

What is the health insurance moratorium period after the 2024 IRDAI circular?

It is a period of sixty continuous months of coverage, defined in the IRDAI Master Circular on Health Insurance Business dated 29 May 2024. After you complete sixty months, the insurer cannot contest a claim except by proving fraud. This replaced the earlier 96-month (8-year) rule under the 2020 regulations.

Does the five-year moratorium mean my claim can never be rejected after 60 months?

No. After sixty months the insurer cannot reject a claim on grounds of non-disclosure or misrepresentation of a pre-existing condition. It can still decline a claim for proven fraud, and it can still apply contractual limits such as sub-limits, co-payment, room-rent caps and permanent exclusions, none of which the moratorium removes.

If I increase my sum insured, does my moratorium restart?

Only on the increased portion. The 2024 circular states that where the sum insured is enhanced, the sixty-month count applies from the date of enhancement only on the enhanced limits. Your original sum insured keeps its existing, earlier completion date, so the clock effectively runs in layers.

Does porting my policy to another insurer reset the moratorium clock?

A clean portability transfer under IRDAI rules carries over your accrued moratorium and waiting-period credit, so it should not restart the count. Confirm the credit transfer in writing before you switch, because a lapse or a break in continuity can reset the clock to zero.

What counts as "proven fraud" that survives the moratorium?

Fraud means deliberate deception the insurer can evidence — fabricated hospital bills, staged or non-existent treatment, or knowingly false declarations made to obtain a benefit. It is a much higher legal standard than ordinary non-disclosure. An honest omission on your proposal form is protected after sixty months; a deliberate lie is not.

Was the moratorium always five years?

No. Policies governed by IRDAI's 2020 health insurance regulations carried a 96-month (8-year) moratorium. The Master Circular of 29 May 2024 reduced it to sixty months, shortening the contestable window by three years for policyholders.

Where can I read the official rule?

The provision sits in the IRDAI Master Circular on Health Insurance Business dated 29 May 2024, available on the regulator's document portal at irdai.gov.in (document reference 4942918). The life-insurance analogue, the three-year incontestability rule, appears in Section 45 of the Insurance Act 1938 on indiacode.nic.in.
