Waiting periods in health insurance: the four types, IRDAI limits and a dated example

What are the waiting periods in health insurance?

A waiting period is a stretch of time after your cover starts during which some claims aren’t paid. Retail policies in India use up to four kinds, and each runs from the start of your first continuous policy.

The codes Excl01 to Excl18 come from standard wording IRDAI introduced in 2019–2020. That circular was repealed in May 2024, but many wordings still use the codes, so they are handy search terms.

The moratorium period is different. It isn’t a waiting period, but the 60-month point after which the insurer can’t contest your disclosure except for fraud.

What are IRDAI’s current limits?

36 months for pre-existing diseases and 36 months for specific diseases or procedures, both under Schedule III of the IRDAI (Insurance Products) Regulations, 2024, which took effect on 1 April 2024. Both were 48 months before that, and some older explainers still show 48.

• Pre-existing diseases: “maximum up to 36 months of continuous coverage” for conditions you declare (clause 7). The regulation adds that insurers may try to offer shorter pre-existing and specific waits. See pre-existing disease for what counts and what to disclose.
• Specific diseases and procedures: defined as “a period up to 36 months” from the start of the policy, during which listed diseases or treatments aren’t covered, except when caused by an accident (clause 1.7).
• Initial waiting period: no fixed length in the rules. IRDAI’s standard Customer Information Sheet (CIS) has a line, “Initial waiting Period: xx days for all illnesses (not applicable in case of continuous renewal or accidents)”, that insurers fill in. 30 days is the common figure.

Can you claim in the first 30 days, or after 1 month?

For an accident, yes, from the first day. For an illness, not during the initial waiting period, but once it ends you can claim for a new illness that isn’t on the specific-disease list and isn’t a pre-existing disease. Listed conditions and declared pre-existing diseases keep waiting, so at 6 months you can claim for dengue but not for a planned cataract operation.

The initial wait applies only to your first policy. It doesn’t apply again when you renew without a break, though many wordings apply it to any increase in sum insured.

What does “30-day waiting period waived” mean?

It means the initial wait doesn’t apply to you. Usually that is because you are renewing without a break, you ported with continuous cover, or the product or your schedule waives it. A waiver of the initial wait doesn’t waive the specific-disease or pre-existing disease waits, so check each line in the schedule.

Which diseases have a 2-year waiting period?

Your policy’s list decides, but many lists include cataract, hernia, joint replacement, kidney and gall bladder stones, piles, fissure and fistula, benign enlargement of the prostate, ENT surgeries, hysterectomy and varicose veins. Some lists put a few items on a longer wait, up to the 36-month limit, so read the months next to each item.

Lists use medical terms: “calculi” are stones and “benign prostatic hypertrophy” is prostate enlargement. Many wordings also say that if a listed condition is also a pre-existing disease, the longer of the two waits applies, and that the list applies even if the condition starts after you buy the policy.

Example: a dated timeline of claims

Example. A ₹5 lakh policy starts on 1 January 2026. It has a 30-day initial wait, a 24-month list that includes cataract, and a 36-month wait for declared high blood pressure. Illness cover starts on 31 January 2026, listed conditions on 1 January 2028, the declared condition on 1 January 2029, and the moratorium on 1 January 2031.

Of ₹4,45,000 billed, the insurer pays ₹2,50,000 and you pay ₹1,95,000. This assumes every bill is otherwise admissible; sub-limits, room rent limits and co-payment would reduce the payouts further.

Do waiting periods restart when you port or raise your sum insured?

Not for the cover you already had, but yes for any increase. IRDAI’s Master Circular of 29 May 2024 lets you carry credit for the specific-disease and pre-existing disease waits, the no-claim bonus and the moratorium to a new insurer (para 12(d)) or a new plan with the same insurer (para 11). The standard CIS says that when the sum insured increases, the waiting period starts afresh only for the enhanced portion.

Example. You held a ₹5 lakh policy from 1 April 2024 and port on 1 April 2026 to a ₹10 lakh policy with a 24-month list and a 36-month PED wait.

A knee replacement on that list in October 2026, with an admissible bill of ₹6,00,000, would be paid up to ₹5,00,000. The other ₹1,00,000 would fall on the extra ₹5 lakh, which is still inside its 24 months.

Credit needs continuous cover. IRDAI’s policyholder-protection Master Circular of September 2024 asks you to apply to port at least 30 days, but not earlier than 60 days, before your renewal date. If the new policy has a longer wait for something, many wordings reduce it by the time you have already served. See health insurance portability.

Do the 2024 limits apply to an older policy?

Check your current wording. IRDAI told insurers to bring existing products in line with the 2024 rules by 30 September 2024, protecting credits already earned, and said insurers “may extend” the new benefits to existing policyholders. The waits in the latest wording and CIS your insurer sent at renewal are the ones that apply.

What to check in your policy

1. CIS item 7, “Waiting period”: the initial wait in days, each specific-disease group in months, and “Pre-existing diseases: Covered after xx months”.
2. Policy wording: search for “Excl01”, “Excl02” and “Excl03”, or for “waiting period”. Read the list of specified diseases and procedures, often in an annexure.
3. Maternity: search “maternity” and “Excl18” to see whether it is covered and after how long.
4. Policy schedule: the declared conditions for each person, any waiver or reduction of a waiting period, and the first inception date for each person.
5. CIS item 12, “Things to remember”: what happens to waiting periods when you change the sum insured, port or migrate.

If the CIS and the policy wording differ, the wording prevails. See how to read a health insurance policy for where each section sits.

Where people get caught out

• New family members. In most wordings each person serves their own waits from the day they join the policy, so a spouse added later starts at zero.
• Booking surgery just before the date. A wait ends on a date. An admission one day early isn’t covered.
• Missing a listed condition. Match your diagnosis to the list before you plan treatment, not after.
• Expecting a higher sum insured to help at once. The increase serves its own waits.
• Renewing late. Renewing after the grace period is a break in policy, and accrued credits can be lost.
• Trusting a “no waiting period” advert. Check which waits the schedule actually waives.
