If you have recently started paying attention to the coverage of medical insurance or received a notice from your insurer about premium adjustments, you are probably familiar with the term “Co-insurance”. Co-insurance is a clause in medical cards that requires the policyholder to share a portion of the medical expenses with the insurance company.
Simply put, when making a medical claim, the insurance company will not pay 100% of the bill. Instead, it requires you to pay a certain percentage of the expenses (usually presented as a percentage, such as 5%, 10%, or 20%). The core purpose of this mechanism is to reduce unnecessary medical spending and the abuse of insurance (such as treating hospitals like hotels), thereby lowering the overall premiums of medical cards from a macro perspective, allowing the public to obtain medical coverage at more affordable prices.
To effectively control Malaysia’s high medical inflation, Bank Negara Malaysia (BNM) requires insurance companies to offer medical card plans with co-payment options to consumers.
This new regulation, aimed at protecting consumers and stabilizing the medical insurance system, includes the following key points:
Medical card Co-insurance is calculated based on a “percentage of the total medical expenses”, but after reaching the maximum out-of-pocket limit (Cap) set in the policy, the remaining expenses will be fully paid by the insurance company.
To eliminate confusion about how to calculate it, here is a real-life example:
Although both Co-insurance and Deductible are mechanisms that require the policyholder to share part of the medical costs, their core difference lies in the calculation method: one is calculated proportionally, while the other is a fixed absolute amount.
Simple comparison:
| Comparison Item | Co-insurance | Deductible |
| Calculation Method | Calculated as a percentage (%) of the total medical bill, e.g., 5% or 10%. | A fixed absolute amount, e.g., RM 500 per hospital admission. |
| Payment Timing & Logic | After any existing Deductible is subtracted, the remaining claim amount is shared proportionally. | A “threshold” that must be paid out-of-pocket before the insurance starts to pay. |
| Risk Perception | Final cost depends on the total bill size (but is capped), so smaller bills mean smaller payments. | Provides a clear minimum cost expectation per admission, regardless of bill size. |
Buying a medical card with 10% Co-insurance has both advantages and disadvantages. It mainly depends on your budget and daily cash flow. Its biggest advantage is significant premium discounts, but you must always have emergency funds ready.
Advantages (Cheaper Premiums):
According to Bank Negara Malaysia data, medical cards with co-payment mechanisms often have premiums 19% to 68% lower than full-coverage medical cards. In the long run, this can save you a substantial amount on premiums and greatly reduce your annual insurance burden.
Disadvantages (Cash Flow Required):
The biggest pain point is that when you or your family members are admitted to or discharged from the hospital, you must have cash ready to pay the Co-insurance. If you don’t usually maintain an emergency fund, a sudden few hundred to a few thousand ringgit expense may cause short-term financial stress.
Recommended Target Audience:
This type of medical card is very suitable for budget-conscious first-time buyers, young and healthy individuals who rarely get hospitalized, or working professionals who already have group medical insurance from their company. The company insurance can cover the Co-insurance first, while your personal medical card handles major illnesses that exceed the company limit.

Is Co-insurance the same as Co-payment?
Not exactly the same. Co-payment is a broad category in medical insurance that refers to all mechanisms where the policyholder and the insurance company share costs. In Malaysia, Co-payment mainly includes two common forms: Co-insurance (percentage sharing) and Deductible (fixed amount sharing).
If the medical bill reaches RM 100,000, will 10% Co-insurance bankrupt me?
No. Because policies usually have a Maximum Out-of-Pocket Limit (Cap / MOOP) protection. Assuming your medical card limit is RM 1,000, even if the total bill is RM 100,000, 10% would originally be RM 10,000, but due to the cap, you only need to pay RM 1,000 and will not go bankrupt due to medical treatment.
Will my existing “full coverage” medical card be forced to include Co-insurance?
No, it will not be added without consent. BNM’s new regulations mainly require insurance companies to provide Co-insurance options for “newly sold policies” or “plans that customers actively request to switch to”. If you hold an old guaranteed renewable policy, you can usually continue with full coverage. However, due to medical inflation, premiums on old policies may face larger increases in the future.
Do I need to pay Co-insurance when going to a government hospital?
Usually not required. According to Bank Negara Malaysia guidelines, if you receive treatment at government healthcare facilities, or in emergency situations (such as a car accident entering the ER), or outpatient follow-up for certain serious illnesses (e.g., cancer or dialysis), the insurance company must exempt your Co-insurance and provide full coverage.
