Health insurance: choosing and using cover

Asha’s employer covers her for ₹3,00,000, but the cover stops on her last working day and leaves out her parents. Five days in a hospital room ₹3,000 a day dearer than a policy allows could cost her family ₹60,000 of a ₹2,00,000 bill, four times the extra rent.

This lesson sizes cover for Asha and her parents from the bills it must pay, follows a new policy’s waiting periods month by month, works out a room-rent limit, walks a cashless claim through its deadlines, and compares a top-up with a super top-up. It is education only: Asha’s family, every policy, bill and premium are invented, and no insurer or policy is recommended.

Cover from a job ends with the job, and your own policy starts with waits

A group policy belongs to the group. IRDAI’s policyholder pages warn that cover bought for a group can stop when you leave it, and that the insurer should then offer you an individual policy to carry on with. Asha’s group covergroup health insurance: A health policy that an employer buys for its employees as one group. The cover can end when you leave the group, and the insurer should then offer you an individual policy. More in “Gratuity, group insurance and other benefits” is a good start, but it is tied to one employer and covers her alone, so she buys a personal policy while she is healthy, because a new policy pays nothing for some things at first. Walk through her invented policy from its first day:

Three kinds of wait apply, and IRDAI’s product regulations cap two of them. The initial wait applies to illness in the first weeks, often 30 days, and never to accidents. A specific waiting periodspecific waiting period: A period of up to 36 months from the start of a health policy during which listed diseases or treatments are not covered, unless they follow an accident. holds back listed treatments for up to 36 months. A pre-existing diseasepre-existing disease: A condition diagnosed, or for which treatment was advised or received, in the 36 months before a health policy began. Once declared, it can be excluded for at most 36 months of continuous cover., one diagnosed or treated in the 36 months before the policy began, may be excluded for at most 36 months of continuous cover, and an insurer may set shorter waits. After 60 months comes the moratoriummoratorium period: Sixty continuous months of health cover, after which no policy or claim can be contested for non-disclosure or misrepresentation, except for established fraud., after which no claim can be contested for non-disclosure except for established fraud.

Every one of these clocks runs only while the cover is continuous. The insurer may not refuse to renew a policy because you claimed, a premium paid within the grace period keeps every credit, and portabilityportability: Moving a health policy to another insurer while keeping the waiting periods already served and the other credits gained, up to the old sum insured. to another insurer carries the waits already served, up to the old sum insured. A lapse starts them all again.

Size the cover from the bills it must pay

Cover is sized from large bills, not average ones: the stays that would hurt most, for every person the policy covers, in the same year. A family floaterfamily floater: A health policy with one sum insured shared by everyone it covers, which any one of them may use up in a policy year. shares one sum insured among everyone on it, so two large bills in one year draw on the same money. The program prices one bad year for Asha and her parents, with invented bills, then lets the bills rise at an assumed 8 % a year:

"""Sizing health cover from the bills it must pay: Asha and her parents, with invented bills.

Cover is sized from large bills, not from averages: the stays that would hurt most, for each person covered, in the
same year. Every bill here is invented for the lesson. Hospital costs are assumed to rise 8 % a year, an assumption
written down for the arithmetic, not a forecast.

  a ₹48,000 premium for parents who are senior citizens: ₹48,000 deductible, limit ₹50,000
  at a marginal rate of 31.2 % it saves ₹14,976 of tax; in the new regime it saves nothing

Her parents’ two bills come to ₹7,50,000, so a ₹5,00,000 floater for them leaves ₹2,50,000 unpaid in that year. The same bills at 8 % a year are ₹16,19,194 in ten years, more than twice as much, and the 8 % is an assumption written down for the arithmetic, not a forecast. Change the rate and the years in the model to see how quickly a sum insured that fits today stops fitting:

At 8 % the model shows ₹9,71,516 after ten years, the same as the program; at 6 %, ₹8,05,881; at 10 %, ₹11,67,184. The model was built for interest, so read its starting amount as today’s bill and its rate as the rise you assume. That is why cover is sized again every few years, and why adding cover above a base, the last section of this lesson, is one way to keep up.

Parents bring one tax rule. In the old regime, section 126 of the Income-tax Act, 2025 deducts premiums for your parents’ health cover up to ₹25,000 a year, or ₹50,000 when they are senior citizens, on top of the same limits for yourself, your spouse and your children; a preventive check-up counts within them, up to ₹5,000. In the old regime, at a marginal rate of 31.2 %, a ₹48,000 premium for senior-citizen parents saves ₹14,976; the new regime of section 202 allows none of it, so for Asha, who is in the new regime, the same premium saves no tax.

A room above the limit cuts the whole bill, not just the room

A policy may cap the room rentroom-rent limit: The most a health policy pays for a hospital room each day, set in rupees or as a share of the sum insured. it pays each day, and the customer information sheet lists such limits among the costs you share. If you take a dearer room, a wording with a proportionate clause does not stop at the room: it pays the room’s associated medical expenses in the same proportion, the limit divided by the rate you chose. That proportionate deductionproportionate deduction: A cut to the associated medical charges of a hospital stay, in the proportion of the room-rent limit to the room's rate, applied when a room above the limit is chosen. is what turns a small upgrade into a large bill. Follow Asha’s mother’s five days through an invented clause:

The program works the same bill, then three other rooms with the same other charges:

"""A room-rent limit and its proportionate deduction, on one invented bill.

Asha's mother is in hospital for five days. Her invented policy pays room rent up to ₹5,000 a day; the hospital's
room costs ₹8,000 a day. Its wording cuts the "associated medical expenses" in the same proportion as the
room limit bears to the room chosen, 5,000 ÷ 8,000, and defines them as the doctors', operation-theatre and nursing
charges. Medicines, consumables, implants and diagnostics are left out of that definition, as IRDAI's 2020 norms on
proportionate deductions required. The wording of each policy decides which charges are cut. The last lines keep the
same doctors', theatre and nursing charges in every room, so that only the clause changes.

In the ₹8,000 room the policy pays ₹1,40,000 and the family ₹60,000, though the room cost only ₹15,000 over its limit. In a ₹6,000 room the family pays ₹25,000, and in a ₹10,000 room ₹85,000. Which charges are cut is set by the policy’s definition of associated medical expenses. In 2020 IRDAI barred insurers from counting pharmacy and consumables, implants and medical devices, and diagnostics among them, and from cutting ICU charges at all; IRDAI’s consolidated health insurance circular of 2024 withdrew those norms, so today each wording decides, and you read it.

The same arithmetic covers the other ways a policy shares costs with you. A co-payment takes its share of every admissible claim, and a sub-limit caps one treatment, as the lesson on insurance basics worked through. The customer information sheet lists all of them, room and ICU limits included, under the financial limits of its cover.

Cashless or reimbursement: who pays the hospital, and how fast

There are two ways to claim. In a cashless claimcashless claim: A claim in which the insurer pays a network hospital directly after authorising the treatment, so the patient pays only what the policy does not cover. at a network hospitalnetwork hospital: A hospital with which an insurer, or its third-party administrator, has an arrangement for cashless treatment of its policyholders., the insurer pays the hospital directly; in a reimbursement claimreimbursement claim: A claim in which the patient pays the hospital and the insurer repays the admissible amount, within 15 days of the claim being submitted. you pay first and the insurer repays you. IRDAI wants insurers to reach 100 % cashless settlement, and its consolidated circulars set the clock for each step. Step through a cashless admission:

The deadlines are the insurer’s, not the family’s:

A reimbursement claim is for a hospital outside the network, or when cashless was not possible. You pay the hospital, keep every bill, prescription and report, and submit the claim with them. Either way, no claim may be rejected for being reported late or for a missing document, and a rejection must cite the clause it rests on and pass the insurer’s claims review committee first.

A top-up deducts per claim, a super top-up per year

Large cover can be built in two layers. A base policy pays from the first rupee, and extra cover starts only above a deductible. IRDAI’s customer information sheet lets a deductible apply per claim, per year or both, and that is the whole difference between the two kinds of extra cover. A top-uptop-up: Extra health cover that pays only the part of a single claim above its deductible, claim by claim, so smaller claims in the same year add up to nothing. applies its deductible to each claim on its own; a super top-upsuper top-up: Extra health cover that pays once the year's admissible claims, added together, pass its deductible. applies it once to the year’s claims added together. The program puts Asha’s parents’ ₹5,00,000 base and ₹10,00,000 of extra cover above ₹5,00,000 through three invented years:

"""A base policy with a top-up or a super top-up, in three invented years of hospital bills.

Asha's parents have a base policy of ₹5,00,000 (invented). Above it they can add ₹10,00,000 of cover that starts only
after a deductible of ₹5,00,000. A top-up applies that deductible to each claim on its own; a super top-up applies it
once to the year's claims added together. Every bill is taken as admissible in full, so only the structure differs. The last structure is a single base
policy of ₹15,00,000, the same total cover from the first rupee.

What the family pays itself, by structure

    base + top-up          nothing
    base + super top-up    nothing
    one ₹15 lakh base      nothing
  two stays, ₹4 lakh and ₹3 lakh:
    base only              ₹2 lakh
    base + top-up          ₹2 lakh
    base + super top-up    nothing
    one ₹15 lakh base      nothing
  one stay of ₹16 lakh:
    base only              ₹11 lakh
    base + top-up          ₹1 lakh
    base + super top-up    ₹1 lakh
    one ₹15 lakh base      ₹1 lakh

Without the base policy, the deductible is the family's to pay
  one stay of ₹7 lakh: top-up alone leaves ₹5 lakh, super top-up alone leaves ₹5 lakh
  two stays, ₹4 lakh and ₹3 lakh: top-up alone leaves ₹7 lakh, super top-up alone leaves ₹5 lakh
  one stay of ₹16 lakh: top-up alone leaves ₹6 lakh, super top-up alone leaves ₹6 lakh

With one stay of ₹7 lakh both kinds pay the ₹2 lakh above the base. With two stays of ₹4 lakh and ₹3 lakh, the top-up pays nothing, because neither claim crosses ₹5 lakh, and the family pays ₹2 lakh; the super top-up adds the year’s ₹7 lakh, pays the ₹2 lakh above ₹5 lakh, and the family pays nothing. Without the base under them, the family would pay the first ₹5 lakh itself. Answer three questions about your own family:

In short: where one stay could pass ₹5 lakh, a base alone is not enough; where two people share cover, or one illness could mean two stays, a super top-up does what a top-up cannot; and the base must stay in place, which matters when part of it is group cover that ends with a job. The table compares cover, not prices: premiums differ by insurer, age and city, so ask for a quote for each structure before you choose.

Practise: choosing and using health cover

Waiting periods, sizing, room rent, claims and top-ups come up in turn, the weakest of them in your answers first. Take every bill as admissible in full unless a question says otherwise:

Interview questions

Warm-up (fresher): What is a room-rent limit, and how can it cut a claim?

It is the most a health policy pays for a hospital room each day. If you take a dearer room, a wording with a proportionate clause pays the associated medical expenses in the same proportion as the limit bears to the rate you chose. With a limit of ₹5,000 a day and an ₹8,000 room for five days, the policy pays the room at ₹25,000 and the ₹1,20,000 of doctors’, theatre and nursing charges at 62.5 %, ₹75,000; with ₹40,000 of medicines and tests paid in full, it pays ₹1,40,000 of a ₹2,00,000 bill. The family pays ₹60,000, four times the ₹15,000 the room cost over its limit. Which charges are cut depends on the wording.

Warm-up (fresher): What is the difference between a top-up and a super top-up?

Both are extra cover that starts above a deductible, and both need a base policy to pay the amount below it. A top-up applies the deductible to each claim on its own, so it pays only for a single claim larger than the deductible. A super top-up applies it to the year’s claims added together. With a ₹5 lakh deductible and two stays of ₹4 lakh and ₹3 lakh in a year, the top-up pays nothing, while the super top-up pays the ₹2 lakh above ₹5 lakh. For one stay of ₹7 lakh, both pay ₹2 lakh. That is why families with several members, or long illnesses, compare the two by the year, not the claim.

Key takeaways

• Group cover can end with the job and covers only the group, so a personal policy is best bought early: illness waits about 30 days, listed treatments and pre-existing diseases at most 36 months, and the moratorium comes at 60.
• Size cover from the large bills of everyone it covers in the same year, and review it, because bills rising at an assumed 8 % a year more than double in ten years.
• A room above the policy’s limit cuts the associated charges in proportion: ₹60,000 of a ₹2,00,000 bill for a room ₹15,000 over its limit, and the wording says which charges are cut.
• Cashless requests are decided within an hour and discharge within three hours, reimbursements are settled within 15 days, and a late insurer pays interest at the bank rate plus 2 %.
• A top-up counts its deductible claim by claim and a super top-up by the year, so two stays of ₹4 lakh and ₹3 lakh are paid only by the super top-up, and both need a base below them.
