What Is Co-Payment in Health Insurance? Meaning & Example

A co-payment in health insurance is a cost-sharing provision under which you pay a specified percentage of an admissible claim, while the insurer considers the remaining eligible amount according to the policy terms. For example, if your policy has a 10% co-payment and your admissible claim is ₹1,00,000, your share would generally be ₹10,000. The insurer may pay the remaining ₹90,000, subject to the policy’s coverage, limits, exclusions and other conditions.

What is an Insurance Premium?

An insurance premium is the amount you pay to an insurer to maintain your policy. Payments may be monthly, quarterly, annually or on another agreed schedule, depending on the policy.

Why it matters: Compare the premium alongside coverage, exclusions, limits and other policy conditions—not price alone.

Co-payment can affect how much you pay during a hospitalisation claim. Before buying or renewing health insurance, it is important to understand the applicable percentage, the expenses to which it applies and whether other cost-sharing provisions also affect your claim.

How Does Co-Payment Work in Health Insurance?

A co-payment specifies the share of an admissible claim that the policyholder must bear. The percentage and calculation method are defined in the policy documents. Consider this simplified example:

Admissible claim amount: ₹1,00,000
Co-payment percentage: 10%
Your co-payment: ₹10,000
Remaining eligible amount: ₹90,000

In this illustration, you bear ₹10,000, and the insurer may pay ₹90,000, provided the claim meets the policy conditions and no other limits or deductions apply. Now consider a 20% co-payment on the same admissible claim:

Admissible claim: ₹1,00,000
Co-payment: 20%
Your share: ₹20,000
Remaining eligible amount: ₹80,000

The higher percentage means a larger share of the admissible claim is borne by you. Important: These calculations use the admissible claim amount, not necessarily the total hospital bill. Excluded expenses, sub-limits, deductibles or other policy provisions may increase your total out-of-pocket cost.

Does Co-Payment Apply to the Entire Hospital Bill?

Not necessarily. Co-payment is generally calculated on the admissible claim amount specified by the policy, rather than automatically applying to every rupee on the hospital bill. For example, suppose a hospital bill is ₹1,20,000, but only ₹1,00,000 is admissible under the policy. If a 10% co-payment applies to that admissible amount, the co-payment would be ₹10,000. The remaining ₹20,000 of the original bill may include expenses that are not admissible under the policy. Those expenses would need to be assessed separately. Your final out-of-pocket amount could therefore include:

The co-payment amount.
Expenses excluded from coverage.
Amounts exceeding applicable sub-limits.
Any applicable deductible or other policy-defined cost-sharing amount.

This is why checking only the co-payment percentage is not enough. Read the policy wording and Customer Information Sheet (CIS) to understand how different provisions interact.

Does Co-Payment Reduce the Sum Insured?

No. According to IRDAI's explanation, a co-payment does not reduce the sum insured. The sum insured is the coverage amount specified in the policy, subject to its terms. A co-payment determines the portion of an admissible claim that the insured must bear. For example, suppose you have a policy with a sum insured of ₹5 lakh and a 10% co-payment. If you make an admissible claim of ₹1 lakh, the illustrative co-payment is ₹10,000. The remaining eligible amount may be paid by the insurer, subject to the policy terms. The sum insured is not automatically reduced by the co-payment percentage itself. However, the amount of cover remaining after a claim can depend on the policy's benefit structure and rules for the policy year. Read the insurer's official documents to understand how claims affect the available coverage.

Co-Payment vs Deductible vs Co-Insurance

These terms describe different forms of cost-sharing, and they should not be treated as interchangeable.

Feature	Co-payment	Deductible	Co-insurance
Basic meaning	A specified share of an admissible claim	A specified amount or threshold the insured must bear under the policy	A percentage-based sharing arrangement, where specified
Typical calculation	A percentage of the applicable admissible claim	A defined rupee amount or another policy-specified threshold	Usually a defined percentage of eligible expenses
What to check	Percentage and calculation basis	Amount, frequency and how it is applied	Percentage and applicable calculation rules

Under IRDAI's explanation, a deductible is a cost-sharing requirement that applies before relevant benefits become payable. Co-payment, by contrast, refers to the specified percentage of the admissible claim borne by the policyholder. The precise terms and application should always be confirmed from your policy wording.

Why Do Some Health Insurance Policies Have a Co-Payment?

A co-payment changes how medical claim expenses are shared between the insurer and the policyholder. Its effect on premiums and the overall value of a policy depends on the particular product. When comparing plans, consider these points:

1. Your Out-of-Pocket Responsibility

A higher co-payment percentage means you may have to bear more of an admissible claim. Consider whether you could comfortably meet that expense if hospitalisation occurs unexpectedly.

2. The Premium Difference

Do not assume that a policy with a co-payment always has a lower premium. Compare actual quotes for similar coverage, sum insured, policy terms and other benefits.

3. Your Existing Financial Resources

Consider your emergency savings and the medical expenses you could reasonably manage yourself. A policy should be evaluated not just by its premium, but also by the potential amount you may have to pay when making a claim.

4. Other Policy Restrictions

A policy may contain co-payment provisions alongside room-rent limits, sub-limits, deductibles, waiting periods and exclusions. These can affect the final claim amount independently of the co-payment. A policy without a co-payment may reduce this particular cost-sharing requirement, but it is not automatically the best choice. Compare the complete coverage and conditions.

What Should You Check Before Buying Health Insurance with Co-Payment?

Before selecting or renewing a policy, review the following details:

Co-payment percentage: Confirm the exact percentage stated in the policy.
Calculation basis: Check whether it applies to the admissible claim and whether different rules apply in specific circumstances.
Applicability: Check whether the provision applies to all claims or only certain treatments, situations or categories of insured persons.
Other deductions: Review deductibles, room-rent restrictions, sub-limits and excluded expenses.
Premium comparison: Compare plans with similar benefits and coverage rather than relying on premium alone.
Customer Information Sheet: Read the CIS for a summary of important benefits, restrictions and cost-sharing provisions.
Official policy wording: Confirm the precise terms with the insurer before buying.

IRDAI advises consumers to examine policy conditions, exclusions, limits and co-payment provisions when purchasing health insurance. You can refer to the regulator's official resources:

These resources explain key insurance concepts and help consumers understand what to review before choosing a policy.

What Is Co-Pay in Medical Insurance?

Co-pay, short for co-payment, is the portion of an admissible medical insurance claim that you must pay yourself under your policy's terms. It is usually expressed as a percentage of the applicable claim amount. For example, if your medical insurance policy has a 10% co-pay and the admissible claim is ₹50,000, your co-payment would be ₹5,000. The insurer may pay the remaining ₹45,000, subject to policy limits, exclusions and other applicable conditions. Before choosing a medical insurance policy, check the co-pay percentage, when it applies and whether other restrictions could increase your out-of-pocket expenses.

Is co-pay mandatory in medical insurance?

Co-pay requirements depend on the specific policy. Check the insurer's official policy wording and Customer Information Sheet to confirm whether a co-payment applies and how it is calculated.
