In short. Under IRDAI's 2024 health insurance rules, a pre-existing disease is one diagnosed or treated within 36 months before the policy began, the waiting period for it cannot exceed 36 months, and after 60 months of continuous cover no claim can be contested for non-disclosure except for fraud. The insurer must also show the claim is actually linked to that condition.
Pre-existing disease, usually shortened to PED, is the most common reason given for rejecting a health claim, particularly for older policyholders. The rejection letter often relies on a single line in a hospital record, "known case of hypertension" or "diabetic for 8 years", and treats it as proof that the policyholder hid something. Sometimes that is fair. Often it is not.
This post explains how to test a PED rejection and what to do about it. The general choice between the Insurance Ombudsman and the consumer commission, and rejections for other reasons, are covered in our post on what to do when an insurance claim is rejected. Our page on banking and insurance laws describes our wider insurance practice.

Can a health insurer reject a claim for a pre-existing disease?
Yes, but only in three situations, and each has conditions. First, if you disclosed the condition when you bought the policy and the claim is for that condition during the PED waiting period stated in the policy, the claim can be excluded. Second, if you knew of a material condition, were asked about it, and did not disclose it, the insurer can reject the claim and may cancel the policy, but only within the first 60 months of continuous cover. Third, if the claim is for a complication of a pre-existing condition, the exclusion can apply only if the link is real and medically supported.
Outside these situations, a PED rejection is a deficiency in service. That includes rejections after the waiting period is over, rejections for non-disclosure after the moratorium, rejections where the condition was diagnosed after the policy began, rejections where you did disclose the condition, and rejections based on a condition that has nothing to do with the illness claimed.
IRDAI changed the rules in 2024, through the IRDAI (Insurance Products) Regulations 2024 and the Master Circular on Health Insurance Business issued on 29 May 2024. The changes favour policyholders, and many insurers' rejection letters and claim teams have been slow to reflect them. Check your dates against the current rules before accepting any PED rejection.
Three kinds of PED rejection and how to test each
| What the insurer says | What the insurer must show | Your usual answer |
|---|---|---|
| Disclosed PED, claim within waiting period | The condition was declared or known, the waiting period has not run, and the claim is for that condition | Check the waiting period in the policy, the start date of continuous cover and portability credit; check that the claim is for the declared condition |
| Non-disclosure or misrepresentation | A material fact known to you was asked about and not disclosed, and the claim is within 60 months of continuous cover | You did not know, were not asked, disclosed it to the agent, or the fact was not material; or the moratorium has passed |
| Illness related to a PED | A medical link between the pre-existing condition and the illness now claimed | No medical connection, or a treating doctor's opinion that the present illness arose independently |
Most rejection letters do not say clearly which of these grounds they rely on. Ask the insurer in writing to specify the ground, the clause and the documents relied on. The answer often shows that the insurer has mixed up the three.
What counts as a pre-existing disease now?
Under the 2024 rules, a pre-existing disease is any condition, ailment, injury or disease that was diagnosed by a physician, or for which medical advice or treatment was recommended by or received from a physician, within 36 months before the date the policy began. Before 2024 the window was 48 months.
Two things follow. A condition diagnosed more than 36 months before the policy began, with no advice or treatment within those 36 months, is not a PED by this definition. And a condition first diagnosed after the policy began is not a PED at all, however chronic it is and however long it may have been developing silently. An insurer cannot treat undiagnosed diabetes as pre-existing because a later test suggests it had been present for years.
The definition looks at diagnosis, advice or treatment, not at symptoms or risk. A family history of heart disease, high cholesterol noticed once in a routine report without any advice, or being overweight is not a pre-existing disease by itself. Insurers do sometimes argue otherwise, and the definition in your policy wording is the starting point for the reply.
The PED waiting period: how long can it be?
The waiting period is the time after the policy starts during which a declared pre-existing disease is not covered. Under the 2024 rules, it cannot be more than 36 months of continuous coverage. Earlier policies commonly had 48 months, and some products offer shorter periods of one or two years, sometimes for an extra premium.
Continuous coverage matters. If you renewed on time every year, the waiting period counts from the start of the first policy. If you ported from another insurer, the time already served with the old insurer is credited under IRDAI's portability rules, to the extent of the earlier sum insured. A break in cover, or a late renewal outside the grace period, can restart the clock, so check the renewal dates carefully.
If you increased the sum insured at a renewal, the waiting period for a PED applies afresh only to the increased amount, not to the original sum insured. An insurer rejecting the whole claim on the ground that the waiting period restarted at the enhancement is applying the rule wrongly.
The 5-year moratorium: when non-disclosure stops mattering
Once a policyholder has completed 60 continuous months of cover, the policy and its claims cannot be contested on the ground of non-disclosure or misrepresentation, except where fraud is established. This is the moratorium. The 2024 rules cut it from eight years to five. The 60 months include time with a previous insurer where the cover was ported or migrated without a break.
The moratorium does not override permanent exclusions written into the policy, and it does not override the policy's sub-limits, co-payments and specific waiting periods. It also applies separately to any increase in the sum insured, which has its own 60 months from the date of the increase. But for the original cover, after five years, an argument that you did not mention your blood pressure in the proposal form is no longer available to the insurer.
Fraud is a high bar. It means deliberate deception, such as concealing a known cancer diagnosis to buy a policy, or forging records. Forgetting to mention a minor condition, or answering a vague question in good faith, is not fraud. If an insurer invokes fraud after the moratorium, ask it to state the particulars in writing.
Non-disclosure: what did you actually have to disclose?
A health policy is a contract of the highest good faith, and the proposer must disclose material facts within their knowledge in answer to the questions asked. The Supreme Court said so in Satwant Kaur Sandhu v New India Assurance (2009), upholding the rejection of a mediclaim where the insured had chronic diabetes and renal failure and did not disclose them. The Court also said the duty extends to facts the proposer actually knew, and that a material fact is one that would influence a prudent insurer in deciding whether to accept the risk or at what premium.
That gives you three lines of answer. Did you know? A condition you had never been told about is not something you could disclose. Were you asked? The proposal form decides what was asked, and a question about "any disease of the heart" may not cover an isolated raised reading. Was it material? A well-controlled condition, declared elsewhere in the form or revealed by the insurer's own pre-policy check, may not have changed the insurer's decision at all.
The other side of the coin is Manmohan Nanda v United India Assurance (2021). There the Supreme Court held that an insurer, having issued the policy after assessing the medical condition the proposer had disclosed, could not later reject the claim by pointing to that same condition. Where the insurer conducted a pre-policy medical examination, or had your reports and still issued the policy, its argument that it was misled becomes much weaker.
Proposal forms are often filled in by an agent or a bank's sales staff, sometimes online on the proposer's behalf. If you told the agent about a condition and the form does not show it, say so in your reply, name the agent if you can, and look for any message or email that shows what you told them.
The "known case of" line in the discharge summary
Most PED rejections rest on a line in the hospital's admission notes or discharge summary: "K/C/O HTN x 6 years", "known diabetic for 10 years", "history of asthma since childhood". These notes are usually written by a junior doctor at admission, on the basis of what a worried relative said in the emergency room, and the duration is often a guess. Insurers treat them as conclusive.
They are not conclusive. A history noted at admission is evidence, but it can be explained and contradicted. The best answers are a certificate from your regular doctor stating when the condition was first diagnosed and what treatment began when, prescriptions and pharmacy bills showing when medication started, earlier health check-up reports showing normal readings, and if necessary a clarification from the treating hospital that the duration was recorded from an informal history.
When Advocate B.K. Singh reads a PED repudiation, the first document he asks for is not the discharge summary but the proposal form, because the case turns on what was asked and what was answered. The second is the earliest dated medical record of the condition. Put those two next to the policy start date and the rejection usually either holds or falls apart within minutes.
Is the illness actually related to the pre-existing condition?
A PED exclusion applies to the pre-existing condition and its complications, not to every illness the policyholder suffers. If you declared hypertension and are hospitalised for appendicitis, a fracture or dengue, the PED clause has nothing to do with the claim. Insurers sometimes reject such claims anyway, relying on a general statement that the policyholder had a PED.
Harder cases involve conditions that are medically linked, such as diabetes and kidney disease, or hypertension and a heart attack or stroke. Here the insurer will say the present illness is a complication of the PED. The answer depends on the medical facts: whether the condition was controlled, whether there were other causes, what the treating doctor recorded. An opinion from the treating doctor, or an independent specialist, explaining the cause of the present illness carries real weight before the Ombudsman and the commission.
Do not concede the link because it sounds plausible. Many people with controlled diabetes or blood pressure develop heart disease for other reasons, and the burden is on the insurer to justify the exclusion it relies on, with medical reasoning, not a general assertion.
The rules that apply to a PED rejection
IRDAI (Insurance Products) Regulations 2024
Framework regulations for insurance products, under which IRDAI issued the Master Circular on Health Insurance Business on 29 May 2024.
Master Circular on Health Insurance, 29 May 2024
The 36-month PED definition and maximum waiting period, the 60-month moratorium, the Customer Information Sheet, cashless timelines (authorisation within one hour, final discharge within three hours), and the requirement that a claim be rejected only with the approval of the insurer's product management committee or a claims review committee, with specific reasons tied to the policy terms.
Insurance Ombudsman Rules 2017
Complaints about rejected or partly settled claims up to ₹50 lakh, filed within one year of the insurer's final reply, after a written grievance to the insurer.
Consumer Protection Act 2019
A wrongful repudiation is a deficiency in service under s.2(11); complaint within two years under s.69; reliefs under s.39 include the claim amount, interest, compensation and costs.
How to respond to a PED rejection, step by step
Work through these in order. Most of the work is in the first three steps, before anything is filed anywhere.
Get the full claim file
Ask the insurer or TPA in writing for the rejection letter with the clause relied on, a copy of your proposal form, any pre-policy medical report, and any medical opinion or investigation report used. Keep your request and the reply.
Put the dates side by side
Write down the date the first policy began, every renewal and any portability, the date the condition was first diagnosed, and the date of the hospitalisation. Check the 36-month definition, the waiting period and the 60-month moratorium against these dates.
Collect the medical answer
Get a certificate from your regular doctor on when the condition was diagnosed and treated, with old prescriptions and reports. Where the insurer says the illness is a complication, ask the treating doctor to state the cause of the present illness.
File a written grievance
Write to the insurer's grievance officer, stating which ground the insurer seems to rely on and why it fails, with the documents. Register the grievance on Bima Bharosa as well and keep the acknowledgment.
Choose the forum
If the grievance fails, decide between the Insurance Ombudsman (up to ₹50 lakh, free, within one year) and the consumer commission (within two years, with compensation and costs). Do not file in both.
Present the case simply
Lead with the dates and the proposal form, then the medical certificate, then the policy clause. Before the Ombudsman or the commission, a one-page chronology with document references does more than pages of argument.
A made-up example: the line that said "hypertensive for 6 years"
Here's a made-up example. Sunita, 61, lives in Dwarka. She bought an individual health policy in March 2023 through a bank's relationship manager, who filled in the proposal online. She answered no to the question on high blood pressure, because her family doctor had first put her on medicine for it in November 2022, after two high readings, and she understood it as a precaution. In August 2026 she is admitted with chest pain and has an angioplasty. The bill is ₹4.6 lakh.
The admission note says "k/c/o HTN x 6 years". The insurer rejects the claim for non-disclosure of hypertension, cites the discharge summary, and says the heart condition is a complication of the undisclosed PED. Her family doctor certifies that hypertension was first diagnosed in November 2022, with the prescription and pharmacy bills to show it. Her daughter confirms that the "6 years" came from her own confused answer in the emergency room.
On these made-up facts, the hypertension was diagnosed within 36 months before the policy, so it was a PED, and it was arguably material. But the rejection still has problems. The duration in the discharge summary is wrong. The question of whether Sunita understood two readings and a precautionary tablet as a disease she had to declare, in a form filled in by the bank's staff, is a fair one. And the cardiologist's note records other risk factors for the blockage. And the insurer issued the policy to a 58-year-old without asking for a single medical test.
Her claim is within ₹50 lakh, so she goes to the Insurance Ombudsman in Delhi after a written grievance. Had her policy been 60 months old at the time of the claim, the non-disclosure ground would not have been open to the insurer at all, and the case would have been short.
Cashless denied at the hospital for a pre-existing disease
If the insurer or TPA denies cashless treatment at the hospital on PED grounds, that is not the end of the claim. A cashless denial is often based on limited information at admission. Ask for the denial in writing, pay the hospital, keep every bill and report, and file a reimbursement claim after discharge with full documents, including the medical certificates on when the condition began.
Under the 2024 rules, insurers must decide cashless requests within one hour and final discharge within three hours of the hospital's request. Extra charges caused by the insurer's delay at discharge are to be borne by the insurer, not by you. Note the times of the requests and replies; they matter if there is a dispute over delay.
The reimbursement claim is assessed afresh, and a cashless denial does not bind the insurer to reject it. Many claims denied cashless are paid on reimbursement once the full record is before the claims team.
Portability, group policies and policy cancellation
If you ported from one insurer to another without a break, the waiting periods and the moratorium already served carry over, to the extent of the earlier sum insured. Keep the old policy schedules and the portability approval; insurers sometimes reject on the basis that the new policy is only a year old, ignoring the ported years.
Group health policies taken by employers often cover pre-existing diseases from the first day, without waiting periods. If you leave the job, the group cover ends, and IRDAI's rules allow you to move to an individual policy with credit for the time covered under the group policy, subject to the insurer's underwriting and conditions. Ask the insurer for this before the group cover ends, not after.
Insurers sometimes cancel the policy along with a PED rejection, on the ground of non-disclosure. A cancellation must follow the policy's cancellation clause and IRDAI's rules, with notice, and after the moratorium it cannot be based on non-disclosure except for established fraud. Challenge an improper cancellation in the same grievance as the claim, because losing the cover at an older age is often a greater loss than the claim itself.
Documents to collect for a PED dispute
Policy papers
- All policy schedules from the first year, with renewal dates
- Proposal form and any medical questionnaire
- Customer Information Sheet and policy wording
- Portability or migration approval, if any
Medical papers
- Discharge summary, admission notes and bills
- Certificate from your regular doctor on date of diagnosis
- Earliest prescriptions and pharmacy bills for the condition
- Earlier health check-up reports, including any pre-policy medical report
Dispute papers
- Cashless denial and rejection letters
- Your grievance to the insurer and its reply
- Messages or emails with the agent or bank staff who filled the form
- Bima Bharosa grievance reference
Mistakes that weaken a PED dispute
- Accepting the discharge summary as fact. The duration noted at admission is often wrong. Contradict it with dated records, not just a denial.
- Not asking for the proposal form. Without it, you are arguing about questions you cannot see. Insurers are expected to give you a copy, so ask in writing.
- Ignoring the ported years. If you ported, count the waiting period and moratorium from the first policy with the earlier insurer.
- Conceding the medical link. Do not agree that a heart attack or kidney problem is a complication of a PED without a doctor's opinion on the cause.
- Changing your story. If you told the insurer one thing at the claim stage and another in the grievance, the inconsistency becomes the insurer's main point. Get the facts straight before you write.
- Missing the Ombudsman's one-year window. The limit runs from the insurer's final reply. Waiting for the insurer to reconsider repeatedly can use up the year.
- Letting the policy lapse during the dispute. Keep renewing the policy while you contest the claim. A break in cover can cost you the waiting periods and moratorium you have built up.
Ombudsman or consumer commission for a PED claim?
For most PED disputes about a single hospitalisation, the Insurance Ombudsman is the practical first choice: it is free, it is quick, it hears many such cases and it understands the IRDAI rules well. The claim must be within ₹50 lakh and filed within one year of the insurer's final reply.
The consumer commission is better where the claim is larger, where the insurer has also cancelled the policy and you want it restored, where the medical link needs expert evidence, or where you want compensation for harassment and costs. The commission is chosen by the premium paid, which usually means the District Commission; see our post on which consumer commission has pecuniary jurisdiction. Filing is online, as explained in our post on filing a consumer complaint on e-Jagriti, and the two-year limit is discussed in our post on condonation of delay in consumer complaints.
If the dispute is really about the hospital's treatment rather than the insurer's decision, that is a separate matter; our post on medical negligence complaints against a hospital or doctor covers it.
What to do this week after a PED rejection
- Keep the policy renewed; do not let it lapse during the dispute
- Ask the insurer in writing for the proposal form, the clause and the documents relied on
- List the policy start date, renewals, portability and the date of first diagnosis
- Get your regular doctor's certificate and the earliest prescriptions for the condition
- Ask the treating doctor for a note on the cause of the present illness if a link is alleged
- File a written grievance with the insurer and register it on Bima Bharosa
- Diarise one year from the final reply for the Ombudsman and two years for a consumer complaint
Having the rejection read against the rules
PED rejections are decided on dates and documents more than on argument. Once the policy history, the proposal form and the first diagnosis are laid out together, it is usually clear whether the insurer has a real ground or has applied an old rule to a new policy.
If you want an advocate to read the rejection and the policy before you reply, the team of Advocate B.K. Singh at B.K. Singh & Associates can look at the papers and tell you which ground the insurer relies on, whether it holds under the current rules, and which forum to use. You can reach us through the online legal enquiry form, and our pages on consumer and competition laws and consumer court matters in Delhi explain how we handle insurance disputes.
Frequently asked questions
What is a pre-existing disease in health insurance now?
Under IRDAI's 2024 rules, it is any condition diagnosed by a physician, or for which medical advice or treatment was recommended or received, within 36 months before the policy began. Earlier the window was 48 months. A condition first diagnosed after the policy began is not a pre-existing disease.
What is the maximum waiting period for pre-existing diseases?
The waiting period for a declared pre-existing disease cannot exceed 36 months of continuous coverage under the 2024 rules. Some policies offer shorter periods. Time served under an earlier policy that was ported without a break counts towards it.
What is the 5-year moratorium in health insurance?
After 60 continuous months of cover, the insurer cannot contest the policy or a claim on the ground of non-disclosure or misrepresentation, except where fraud is established. It does not remove permanent exclusions, and any increase in the sum insured has its own 60 months.
Can my claim be rejected because the discharge summary says "known case of" a disease?
The insurer often relies on that line, but it is not conclusive. If the duration recorded is wrong, contradict it with your doctor's certificate on the date of diagnosis, old prescriptions and earlier reports. If the condition was disclosed or the moratorium has passed, the line may not matter at all.
Can the insurer reject a claim for an illness unrelated to my pre-existing disease?
No. A PED exclusion applies only to the pre-existing condition and its genuine complications. A claim for an unrelated illness, such as a fracture or an infection, cannot be rejected merely because you have a PED.
What if the agent filled in my proposal form wrongly?
Explain this in your grievance and give whatever evidence you have of what you told the agent or bank staff, such as messages or emails. Where the insurer's own representative filled in the form, commissions and Ombudsmen look closely at whether the policyholder actually concealed anything.
Does a pre-policy medical check-up help my claim?
Often, yes. If the insurer examined you or had your reports before issuing the policy, it is harder for it to say it was misled about a condition those tests would have shown. The Supreme Court made a similar point in Manmohan Nanda v United India Assurance (2021).
My insurer cancelled my policy after rejecting the claim. What can I do?
Challenge the cancellation in the same grievance as the claim, asking the insurer to state the legal basis. After the 60-month moratorium, a policy cannot be cancelled for non-disclosure except for established fraud. If the grievance fails, the Ombudsman or the consumer commission can examine the cancellation.
Does porting my policy restart the waiting period for pre-existing disease?
No, if the porting was done without a break. The time already served is credited to the extent of the earlier sum insured. Any additional sum insured taken at the time of porting may carry a fresh waiting period for that additional amount.
Should I go to the Ombudsman or consumer court for a PED rejection?
For a claim within ₹50 lakh where you want the claim paid, the Insurance Ombudsman is usually quicker and free. For larger claims, policy cancellation disputes, contested medical questions or where you want compensation and costs, the consumer commission is often better.
Can I claim compensation for a wrongful PED rejection?
Before a consumer commission, yes. It can order the claim amount with interest, compensation for harassment and mental agony, and costs. The Ombudsman's award is generally limited to the loss and expenses.
Do the 2024 rules apply to my old policy?
The 2024 rules apply to policies issued and renewed under them, and insurers were directed to align their products. If your policy wording still shows older periods, ask the insurer in writing which waiting period and moratorium apply to your renewal. Take advice where the answer affects the claim.
