Co-payment (co-pay) in health insurance: how it works, with a ₹ example

Updated · 7 min read · By PolicyVibe editorial team · 3 sources

Short answer

Co-payment (co-pay) is the share of each admissible claim that you pay yourself, usually a percentage such as 10% or 20%. It is worked out on the amount the insurer has accepted, after non-payable items, room rent deductions and sub-limits, so it adds to those cuts. A co-pay can be voluntary, for a lower premium, or built in, for example for older entrants or treatment in costlier cities.

Key facts

  • IRDAI’s Customer Information Sheet format (2024 Master Circular on health insurance) describes co-payment as a specified amount or percentage of the admissible claim amount, paid by the policyholder.
  • Because co-pay is applied to the admissible amount, it usually comes after the other deductions. Your wording sets the exact order.
  • With a 20% co-pay you pay ₹20,000 of every ₹1 lakh the insurer admits, on every claim, so a ₹10 lakh claim means a ₹2 lakh co-pay.
  • Age-based and zone-based co-pays are product design choices, not IRDAI requirements. IRDAI’s 2024 rules require the policy to disclose any co-pay.
  • A deductible is different: a fixed amount the insurer never pays, per claim or per year, before your cover starts paying.

What is co-payment in health insurance?

Co-payment is a fixed share of each claim that you agree to pay yourself. If your policy has a 20% co-pay and the insurer admits ₹1,00,000, it pays ₹80,000 and you pay ₹20,000. IRDAI’s Customer Information Sheet (CIS) format describes it as “a specified amount/percentage of the admissible claim amount to be paid by policyholder/insured”.

The important word is admissible. The co-pay isn’t worked out on the hospital’s total bill. It is worked out on what is left after the insurer has applied the rest of your policy terms. That is why a 20% co-pay usually costs you more than 20% of the bill. The standard definition IRDAI set in 2020, still used in many wordings, adds that a co-payment does not reduce the sum insured.

In what order is co-pay applied?

Co-pay usually comes last. Insurers commonly work through a claim in this order, but your policy wording decides:

  1. Remove non-payable items, such as gloves, masks and attendant food.
  2. Apply room rent limits and any proportionate deduction.
  3. Cap anything that has a sub-limit.
  4. Apply the co-pay percentage to the admissible amount that is left.

Example: a 20% co-pay on a ₹1.7 lakh bill

Example. Your sum insured is ₹5 lakh, with a room rent limit of 1% a day (₹5,000), an ambulance sub-limit of ₹2,000 and a 20% co-pay. You stay 4 days in a ₹6,250 room. Room rent comes to ₹25,000 and doctor, surgeon, nursing and OT charges to ₹75,000. Medicines and consumables are ₹40,000, diagnostics ₹20,000, non-payable items ₹6,000 and the ambulance ₹4,000. The total is ₹1,70,000.

StepDeductedAmount left
Hospital and ambulance bills₹1,70,000
1. Non-payable items removed₹6,000₹1,64,000
2. Proportionate deduction: 5,000 ÷ 6,250 = 80%, so 20% of the ₹1,00,000 room-linked charges is cut₹20,000₹1,44,000
3. Ambulance capped at its ₹2,000 sub-limit₹2,000₹1,42,000 admissible
4. 20% co-pay on ₹1,42,000₹28,400₹1,13,600 paid by the insurer

You pay ₹56,400, about 33% of the bill. Many people expect to pay 20% of ₹1,70,000, or ₹34,000. The difference comes from the deductions taken before the co-pay. The example assumes your policy, like many, doesn’t cut medicines and diagnostics in proportion.

If your wording applies the co-pay at a different stage, for example before a sub-limit, the result changes. In a cashless claim, the hospital collects your share at discharge.

What kinds of co-pay are there?

A co-pay is either one you chose or one built into the product. The common kinds are:

TypeWhen it appliesWords to search for
VoluntaryYou opted for it in return for a lower premium“voluntary co-payment”, “opted”
Built-in (mandatory)On every claim, as part of the product“co-payment”, “each and every claim”
Age-basedIn some products, when the insured person joined above a set age, such as 60“entry age”, “age of the insured person”
Zone-basedIn some products, when you are treated in a city in a costlier zone than the one your premium was based on. Zone lists are insurer-specific“zone”, “Zone A”, “city”
Non-networkIn some policies, for treatment at a hospital outside the insurer’s network“non-network”, “network provider”
Disease-specificIn some policies, for listed illnesses or procedures, or for pre-existing diseases“specified diseases”, “pre-existing”
Employer group policiesSome group policies apply it to parents’ claims“parents”, “dependants”

These are product design choices rather than IRDAI requirements. IRDAI’s 2024 policyholder-protection master circular requires the policy to state any co-pay limits, and the CIS has a “Co-payment” line under “Financial limits of coverage”.

Co-pay vs deductible: what’s the difference?

A co-pay is a percentage of each admissible claim, while a deductible is a fixed amount the insurer never pays. IRDAI’s CIS format defines a deductible as an amount up to which the insurer will not pay any claim, deducted from the total claim if the claim is bigger.

Example. Compare a 20% co-pay with a ₹25,000 deductible per claim:

Admissible claimYou pay with 20% co-payYou pay with ₹25,000 deductible
₹20,000₹4,000₹20,000 (insurer pays nothing)
₹1,00,000₹20,000₹25,000
₹5,00,000₹1,00,000₹25,000

A co-pay grows with the claim; a deductible doesn’t. Deductibles are the basis of top-up and super top-up plans, explained in top-up vs super top-up.

Is a 20% co-pay worth the premium saving?

It depends on how much you claim, and the arithmetic shows both sides. This is not a recommendation.

Example. Suppose taking a 20% co-pay cuts your premium by ₹10,000 a year, or ₹50,000 over 5 years. You break even when your admissible claims average ₹50,000 a year (₹10,000 ÷ 20%), or ₹2,50,000 over the 5 years.

Admissible claims over 5 yearsCo-pay you payPremium savedNet result
None₹0₹50,000₹50,000 ahead
One claim of ₹1,50,000₹30,000₹50,000₹20,000 ahead
Claims totalling ₹2,50,000₹50,000₹50,000Break-even
One claim of ₹4,00,000₹80,000₹50,000₹30,000 behind
Two claims of ₹3,00,000 each₹1,20,000₹50,000₹70,000 behind

Two points sit outside the table. The saving comes in small yearly amounts, while the co-pay arrives in one go when someone is ill. And a co-pay has no rupee ceiling unless your wording sets one, so the largest claims cost the most.

What to check in your policy

  1. Policy schedule: search for “co-pay”, “co-payment” and “%”. A voluntary co-pay you chose should appear here.
  2. Customer Information Sheet: read the “Co-payment” line under “Financial limits of coverage”.
  3. Policy wording: search for “co-payment”, “admissible”, “entry age”, “zone”, “non-network” and “specified diseases”.
  4. Order of deductions: look for phrases such as “applicable to claim amount admissible and payable” or “after deduction of”.
  5. Group policies: check the employer’s policy schedule or benefits booklet for a co-pay on parents or other dependants.

Where people get caught out

  • Expecting the co-pay on the bill. As the example shows, 20% co-pay plus other deductions can mean paying a third of the bill.
  • Missing an age-based co-pay on a parent’s policy, because it sits in the wording rather than the schedule.
  • Getting treated in a costlier city, for example when parents travel to a metro for surgery, and triggering a zone co-pay.
  • Using a non-network hospital in an emergency without knowing the policy adds a co-pay there.
  • Judging a co-pay only by the premium saved, without working out what one large claim would cost.

Frequently asked questions

What does 20% co-pay mean in health insurance?

You pay 20% of every admissible claim and the insurer pays 80%. On ₹1,00,000 admitted, you pay ₹20,000. Non-payable items and other deductions are taken off before the co-pay, so your total share is usually higher.

Is co-pay calculated on the total hospital bill?

Usually not. Co-pay is applied to the admissible claim amount, after non-payable items, room rent deductions and sub-limits. Your policy wording sets the exact order.

Is co-pay mandatory for senior citizens?

It depends on the product. Some policies apply a co-pay to people who join above a set age, such as 60, and others have none. Check the co-payment clause and your Customer Information Sheet.

What is the difference between co-pay and deductible?

A co-pay is a percentage of each admissible claim, so it grows with the claim. A deductible is a fixed amount the insurer never pays, per claim or per year, before cover starts paying.

Does co-pay apply to cashless claims?

Yes. In a cashless claim the insurer approves its share and the hospital collects your co-pay at discharge, along with any non-payable items.

Can I remove the co-pay from my policy?

Some policies let you drop a voluntary co-pay at renewal, or offer a co-pay waiver for an extra premium. A built-in co-pay usually stays with the product, so ask your insurer what options apply.
