You went to the hospital, received treatment, and submitted the claim.
Your insurance covered the treatment.
But while looking at the final bill, you’re left thinking, “Eh… but why got amount still payable after insurance?”
Confused? Don’t worry, you’re not alone. This is one of the most common sources of confusion when it comes to health insurance in Singapore. Having an Integrated Shield Plan doesn’t necessarily mean your insurer will pay every dollar of the hospital bill.
The contrary is also true: an amount left to pay does not automatically mean that your claim was rejected.
Deductibles, co-insurance, Rider terms, claim limits, your choice of doctor and hospital, and even the type of treatment you received can all affect how much your insurance eventually pays.
Here is how to make sense of it.
💡Quick answer: Why didn’t my insurance pay my full hospital bill?
Your insurance may not pay the entire hospital bill because your policy requires you to share part of the cost, or because certain parts of the bill may fall outside your coverage.
Depending on your policy, the amount left over may come from:
- Your deductible
- Co-insurance or co-payment
- The terms of your Integrated Shield Plan Rider
- Using a non-panel doctor
- Claim or benefit limits
- Treatment or charges that are excluded from coverage
- A pre-existing condition that is excluded under your policy
- Choosing a hospital or ward class above the level your insurance is designed to cover
The important thing to remember is this:
A partially paid claim is not necessarily a rejected claim.
Your insurance may have worked exactly as your policy was designed to work, while still leaving part of the bill to be paid using MediSave and/or cash.
First, understand what your hospital insurance actually covers
Our Integrated Shield Plan comprises two components: your MediShield Life (which all Singapore Citizens and Permanent Residents have) and your personal Hospitalisation Insurance. Your MediShield Life provides basic health insurance protection against large hospital bills.
It is designed primarily around subsidised treatment in Class B2 and C wards in public hospitals. If you choose a higher ward class or private healthcare, MediShield Life may cover a smaller proportion of the bill.
If you purchased personal Hospitalisation Insurance (which can cover a variety of ward types depending on your plan) alongside your MediShield Life, both are collectively known as an Integrated Shield Plan (IP). Different Integrated Shield Plans are designed for different levels of care, such as Class B1, Class A, or private hospitals.
You may also have purchased a Rider, which sits on top of your Integrated Shield Plan and can help reduce the amount you have to pay out-of-pocket.
But even with all three layers, you may still have to pay something.
Here are some of the reasons why.
You may still have a deductible to pay
A deductible is a fixed amount you must pay before your insurance starts paying the remaining eligible claim.
Think of it as the first layer of the bill that needs to be accounted for before the main insurance payout kicks in.
For Integrated Shield Plans, the Ministry of Health Singapore currently sets minimum deductibles ranging from $1,500 to $3,500 per policy year, depending on the level of coverage and ward class used. For a private hospital or Class A admission under a corresponding IP, the minimum deductible is currently set at $3,500.
This also helps explain why smaller hospital bills may sometimes result in little or no payout from the additional private insurance portion of an Integrated Shield Plan.
In MOH’s latest published data on common reasons why insurers did not pay an additional IP benefit, 69% were because the claim was less than or equal to the deductible.
So, if your bill is within the applicable deductible, it does not necessarily mean your insurer “rejected” the treatment. The amount may simply not have crossed the threshold for a payout under that part of your policy.
Not sure if your plan covers what matters most?

There may be co-insurance or co-payment after the deductible
Now, just because your hospital bill has exceeded your deductible of $3,500. It still doesn’t necessarily mean that your insurance will pay 100% of everything that comes next.
Most health insurance plans require some form of cost-sharing. One reason is to encourage more considered healthcare use and reduce “buffet syndrome”, which is the tendency to consume more healthcare services when there is little or no cost to the patient.
Under MediShield Life, for example, co-insurance is a percentage of the claimable amount that you have to pay after the deductible. The percentage decreases as the claim amount increases.
Similar to MediShield Life, your private Hospitalisation Insurance and its corresponding riders also have their own cost-sharing structures.
This is why it is useful to think of a hospital claim as a sequence:
The exact sequence and amounts will depend on the type of policy you have.
Having a Rider does not necessarily mean a $0 hospital bill
You may remember the good old days where having a Rider meant that you did not have to pay anything out-of-pocket. But… things have changed.
Since 2019, while Riders could still cover your deductible, MOH required all Riders to include a minimum 5% co-payment feature. (This broke our hearts, to be honest). Additionally, further changes were made to new Riders purchased from 1 April 2026. These new Riders can no longer cover the minimum IP deductible. There is also still a minimum 5% co-payment requirement, with the co-payment cap set at a minimum of $6,000 per year, excluding the applicable minimum deductible.
If you have an older Rider, it may work differently depending on when you purchased it and your individual policy terms.
That means two people can undergo the same procedure at the same hospital and still end up paying different amounts, even if both say:
“I have an Integrated Shield Plan and Rider.”
The Rider type and version matter.
Imagine you have a private hospital Integrated Shield Plan with a new Rider and an eligible hospital bill of $20,000.
For a simplified illustration:
- Hospital bill: $20,000
- Applicable deductible: $3,500
- Amount remaining: $16,500
- 5% co-payment on the remaining amount: $825
Your share in out-of-pocket costs in this simplified example would therefore be:
$3,500 + $825 = $4,325
This does not necessarily mean that $4,325 must come entirely from your bank account. Depending on the treatment and prevailing withdrawal limits, you may be able to pay some or all of the out-of-pocket costs using MediSave.
Your doctor may not be on your insurer's panel
Let’s move on to panel doctors and hospitals. Most insurers maintain panels of healthcare providers, and you may receive benefits such as pre-authorisation and lower co-payment when you use eligible panel providers.
Depending on your policy, choosing a non-panel specialist could mean:
- A different co-payment
- Lower claim limits
- Different Rider benefits
- Losing access to certain panel-related benefits
This does not necessarily mean you cannot claim at all.
It means the claim may be assessed differently from one involving a panel doctor.
That is why checking whether your specialist is on your insurer’s panel before a planned procedure can affect your eventual out-of-pocket cost.
Your insurance may have claim limits
As much as we want it to be, insurance coverage is not always unlimited.
Policies may limit certain treatments, benefits, periods, or overall claims.
Take your MediShield Life, for example. It applies claim limits depending on the type of treatment and length of hospital stay and currently has a maximum claim limit of only $200,000 per policy year.
Integrated Shield Plans may provide additional coverage above MediShield Life, but they also have their own policy terms and benefit limits (typically much higher than MediShield Life; depending on your plan, it can go up to $2,000,000).
If part of your bill exceeds an applicable limit, you may have to pay the excess through another insurance plan (e.g. Critical Illness Plan, Corporate Insurance), MediSave, or cash, depending on what is available to you.
Some parts of your hospital bill may not be covered
A hospital bill contains many different charges.
Just because the main procedure is claimable does not automatically mean that every item on the bill qualifies for reimbursement.
Every health insurance policy contains its own exclusions and conditions. According to the Life Insurance Association Singapore, exclusions vary by policy and set out circumstances in which benefits will not be paid.
This is another reason your insurer’s approved or claimable amount may be lower than the hospital’s total bill.
If you are unsure about a particular charge, check the itemised hospital bill and your insurer’s claims statement, not just the final outstanding amount.
A pre-existing condition may be excluded under the private insurance portion
Your hospital or ward choice may be above your level of coverage
The type of insurance you have matters just as much as having insurance in the first place.
An Integrated Shield Plan may be designed for:
- Class C and B2 wards
- Class B1 wards
- Class A wards
- Private hospitals
If your policy is designed for a lower level of care and you choose a higher ward class or hospital category, you may have to pay a larger share of the bill.
The same principle applies to MediShield Life. It is designed to provide its highest level of coverage for subsidised Class B2/C treatment. For higher ward classes and non-subsidised care, the bill may first be adjusted using a pro-ration factor before MediShield Life claim limits are applied.
This is why simply knowing that you “have hospital insurance” is not enough.
You also need to know what level of hospital care your plan was designed to cover.
But my insurer approved my treatment. Shouldn't that mean everything is covered?
Not necessarily.
For planned treatments, some insurers offer pre-authorisation, which can help you understand how much of an expected treatment cost may be covered before you proceed.
But pre-authorisation is not a 100% guarantee of full reimbursement from your insurer.
Your eventual payout is still subject to your policy terms, including applicable deductibles, co-payments, limits, and other conditions.
In other words:
“Approved” does not necessarily mean “100% paid.”
If you already have a hospital bill in front of you, compare the itemised bill with your insurer’s claims statement.
Instead of looking only at the amount your insurer paid, look for why the remaining amount was not paid.
- Was it the deductible?
- Co-payment?
- A benefit limit?
- A non-covered charge?
- A panel requirement?
That distinction tells you much more about how your insurance is actually working.
Know your coverage, before you need it
Your Integrated Shield Plan is designed to protect you from healthcare costs, but it is not necessarily designed to pay every dollar of every hospital bill.
So, even when a treatment is covered, you may still have a deductible, co-payment, or other amount to account for.
With different Integrated Shield Plans, Rider generations, panel arrangements, and benefit limits in Singapore, two people receiving similar treatment can have very different claim outcomes.
So when you see an outstanding amount after insurance, do not immediately assume:
“My insurance didn’t cover me.”
The better question is:
“Which part of my bill was not covered, and why?”
Understanding that difference can help you know what to check before your next hospital visit and give you a more realistic picture of what your coverage can actually do.
