Lump Sum vs Indemnity — How Critical Illness Payouts Work
The two ways health insurance pays — indemnity, which follows the actual bill, and fixed benefit, which pays the agreed sum — and what the difference means when a person holds more than one policy.
Two ways to pay
Health insurance pays out in one of two ways. An indemnity policy reimburses the actual hospital expenses, against bills and medical records, up to the sum insured and subject to the policy's terms. The payout follows the loss: a smaller bill means a smaller payment.
A fixed-benefit policy, such as critical illness cover, pays the agreed sum insured once the claim conditions are met, whatever the treatment cost. No proof of spending is asked for, so the money can be used for any purpose, for example treatment, lost income or loan instalments.
Why the two behave differently
Indemnity rests on the idea that insurance makes good a loss and no more. The insurer therefore needs to see what was spent, and the payment can never exceed it.
A fixed-benefit contract asks a different question: did the event defined in the policy happen? If it did, the sum agreed at the start is paid. What has to be proved is the diagnosis and the other claim conditions, not the spending.
More than one policy
The difference shows most clearly when a person holds several policies. Indemnity policies reimburse actual expense, so the total paid across them cannot exceed the bill. Under IRDAI's Master Circular on Health Insurance Business (29 May 2024), the policyholder chooses the primary insurer, and that insurer coordinates the balance with the others.
Fixed-benefit policies are not shared in this way. A claim can be made on every one of them, and each pays its own sum insured when its own claim conditions are met.
Holding both kinds
The two kinds of cover answer different questions, so one illness can lead to a claim under each. The indemnity claim is assessed against the bills and the policy's terms. The critical illness claim is assessed against the definition, the waiting period and the survival period. A fixed benefit is not normally reduced by what another policy pays, unless the policy itself says so.
Rules at a glance
What a bill does not show
Illustration, with assumed figures: Kavita, 45, runs a small tailoring unit in Coimbatore. She is diagnosed with an illness covered by her critical illness policy and cannot work for four months. Her indemnity policy deals with the hospital bill. The critical illness policy pays its sum insured of ₹15 lakh on a valid claim, and she uses part of it for the unit's rent and her home-loan instalments during those months. No receipts are asked for, because the policy pays on the diagnosis and not on the spending.
The same illness under each kind of policy
- Assumptions of the example: every bill is fully admissible, no co-pay or sub-limit applies, and every critical illness claim meets its policy's conditions.
- One indemnity policy, sum insured ₹10,00,000, hospital bill ₹3,00,000: the policy pays the bill, ₹3,00,000, because it is lower than the sum insured.
- One critical illness policy, sum insured ₹10,00,000, same bill of ₹3,00,000: the policy pays the agreed ₹10,00,000.
- Two critical illness policies of ₹15,00,000 each, medical bills ₹8,00,000: each pays its own sum insured, so ₹15,00,000 + ₹15,00,000 = ₹30,00,000.
- Two indemnity policies of ₹5,00,000 each, bill ₹8,00,000: the insurer chosen as primary pays up to its ₹5,00,000, and the balance of ₹8,00,000 − ₹5,00,000 = ₹3,00,000 is settled under the second policy. Total ₹8,00,000, the amount of the bill, not ₹10,00,000.
Result. Indemnity payments stop at the bill; fixed-benefit payments are the agreed sums, added together across policies.
Key points
- An indemnity policy reimburses actual hospital expenses up to the sum insured, against bills.
- A fixed-benefit policy pays the agreed sum insured once the claim conditions are met, whatever the treatment cost.
- A fixed-benefit payout needs no proof of spending and can be used for any purpose.
- Across several indemnity policies the total paid cannot exceed the bill; the policyholder chooses the primary insurer.
- Fixed-benefit policies each pay their own sum insured on a valid claim.
Common misunderstandings
- A critical illness policy does not top up a hospital bill: its payout is unrelated to the bill, which may be lower or higher than the sum insured.
- Two indemnity policies do not pay the same bill twice: together they pay no more than the actual expense.
- Two critical illness policies are not shared between insurers: each pays its own sum insured on a valid claim.
- No proof of spending does not mean no proof at all: the diagnosis must still be shown to meet the policy's definition.
Questions people ask
Can the lump sum be spent on something other than treatment?
Yes. A fixed-benefit payout can be used for any purpose, and no proof of spending is required.
If the treatment costs more than the critical illness sum insured, does the policy pay more?
No. The policy pays the agreed sum insured, neither more nor less, whatever the treatment costs.
With two indemnity policies, who decides which insurer pays first?
The policyholder chooses the primary insurer, who coordinates the balance with the other insurer.
