If you have gone for a hospital procedure before, you may be familiar with this: your doctor painstakingly submitting paperwork to your insurer, and receiving the news you were hoping for: approval from your insurer to move forward with this surgery.
You breathe a sigh of relief because it sounds reassuring. And it is.
But before you go around declaring that your entire hospital bill is covered, you have to look at the fine print. Does “approved” really mean your insurer will pay your entire hospital bill?
Not necessarily.
An approval by your insurer just means that your treatment or hospital admission is ELIGIBLE for coverage under certain conditions. It does not necessarily mean that every dollar on your final hospital bill will be paid.
In the good old days, when you had health insurance, it usually meant that as long as all the terms and conditions were met, your entire bill would be covered. Zero out-of-pocket for you. But after a while, the government felt this allowed policyholders a free-for-all, where we claimed for “everything,” so they put new rules in place requiring us to pay at least 5% of the hospital bill. They hoped this would curb what they called “buffet syndrome.”
Now, the amount you still need to pay depends on your policy, Rider, deductible, co-payment, panel arrangements, claim limits, and even what eventually appears on your hospital bill.
So before interpreting “approved” as “fully covered”, here is what you should know.
Quick answer: Does insurance approval mean my hospital bill is fully covered?
No. An approved treatment or claim does not automatically mean your entire hospital bill will be paid by insurance.
Depending on your plan, you may still have to pay a deductible, co-insurance, or co-payment. Certain charges may also fall outside your policy’s claim limits or coverage.
If you have an Integrated Shield Plan (IP) Rider, it may reduce part of your share of the bill, but the amount depends on your Rider and its terms.
MOH also requires IPs to include deductibles and co-payments. For new IP Riders sold from 1 April 2026, Riders cannot cover the minimum IP deductible, and a minimum 5% co-payment requirement continues.
That is why it is important to understand what has been approved, how much has been approved, and what you may still need to pay.
First, what does “approved” actually mean?
This is where many of us tend to get confused.
You may hear that something has been “approved” at several points in your healthcare journey.
Your treatment has received pre-authorisation
Pre-authorisation is when your insurer reviews a planned admission or procedure before it takes place.
It can give you greater certainty that the planned treatment is covered, subject to your insurer’s terms and the information submitted.
The Life Insurance Association Singapore encourages policyholders to use their insurer’s pre-authorisation service, where available, to confirm coverage before planned day surgery or hospitalisation.
But pre-authorisation should not automatically be read as:
“Whatever the final hospital bill is, my insurer will pay all of it.”
Your actual payout may still depend on the final bill and your policy terms.

Your hospital has received a Letter of Guarantee
Your claim has been approved
Even after treatment, an “approved claim” doesn’t always mean the full amount claimed is payable. At the end of the day, after your claims have been approved, there may still be a small amount that you’ll have to pay out of pocket. If eligible, you may pay this amount with your MediSave or through cash.
Why do I still have to pay even after my insurer approves the treatment?
There are several possible reasons.
You may still have a deductible
A deductible is the fixed amount you pay before insurance starts paying its share of an eligible claim.
For Integrated Shield Plans, MOH sets minimum deductibles depending on the ward class and type of treatment. As at 2026, these range from $1,500 to $3,500 for hospital treatment, with separate minimum deductibles applying to day surgery or short-stay wards.
So even when your treatment is covered, you may still have to pay part of the bill.
For new IP Riders sold from 1 April 2026, the Rider cannot cover the minimum IP deductible.
Your own Rider may work differently depending on when you purchased it and its specific policy terms.
You may still have co-insurance or co-payment
Insurance usually does not work as: Covered = insurer pays 100%.
You may be required to share a percentage of the eligible bill.
Under the current IP Rider framework, a minimum 5% co-payment requirement remains.
Some Riders can reduce your share of large eligible bills by applying an annual co-payment cap, although the conditions for that cap can matter.
For new Riders introduced under the revised framework from April 2026, the minimum annual co-payment cap is $6,000, excluding the minimum IP deductible. The cap applies to eligible claims, such as panel or pre-authorised claims.
So even if your treatment is approved, you may still have to pay a portion.
Your doctor may be outside your insurer's panel
This detail can make a big difference.
You may have a private hospital Integrated Shield Plan and still receive coverage when seeing a non-panel specialist, depending on your policy.
But the benefits may differ.
Panel arrangements can affect things such as:
- How much your insurer covers
- Whether certain co-payment caps apply
- Whether pre-authorisation is available or required
- The amount you ultimately pay yourself
MOH specifically notes that co-payment caps under the revised Rider framework apply to eligible claims such as panel or pre-authorised claims.
So before treatment, check both the hospital and the specialist, rather than assuming that being treated at a covered hospital automatically means every doctor is treated the same under your policy.
Not every item on the hospital bill may be claimable
Another common assumption we may have is:
“If the procedure is covered, everything associated with the hospital stay must be covered too.”
That may not always be the case.
Your insurer assesses claims according to the scope and limits of your policy. Certain expenses may therefore receive limited coverage or no coverage depending on your policy.
Medical necessity can matter too.
For example, LIA has explained that if a medical condition can appropriately be treated in an outpatient or day-surgery setting but a patient chooses inpatient admission instead, additional room and board charges arising from that hospitalisation may not be covered because the inpatient stay was not medically necessary.
So the important question is not just whether the main procedure is covered.
It is also whether all the individual charges associated with your care are claimable under your plan.
Your final treatment may be different from what was originally approved
Pre-authorisation happens before treatment.
But healthcare does not always follow the original plan exactly.
Sometimes a doctor may discover something unexpected during a procedure, therefore additional tests may be required. Your hospital stay may become longer, or another specialist may need to be involved.
Your final bill can therefore look different from the treatment plan originally submitted for approval.
That does not automatically mean those additional costs will not be covered.
But your insurer may need to assess them separately against your policy terms before determining the final payout.
This is one reason why an estimated insurance payout before admission and the final claim amount after discharge may not be identical.
Your policy may have claim limits
Your plan may also limit the amount payable for certain treatments, services, or periods of care.
If your eligible medical expenses exceed an applicable limit, the remaining amount may fall to you even though the claim itself is approved.
What about MediSave? Can it reduce what I pay in cash?
Possibly, and that’s the beauty of knowing how to stack your layers so you can reduce the amount you actually have to pay out of pocket.
An amount that is not paid by your insurer does not automatically mean you must pay the entire balance in cash.
Depending on the treatment and prevailing withdrawal limits, you may use your MediSave for eligible healthcare expenses, including certain deductibles and co-payments.
Approved is good news. It's not the same as $0.
Getting approval from your insurer before a planned hospital treatment can provide valuable reassurance.
It means you have more information before going ahead with care.
But insurance approval and full coverage are two different things.
Your eventual hospital bill may still include a deductible, co-payment, Rider, MediSave, claim limits, or expenses not covered under your policy.
Understanding that difference before treatment can make the final bill much less surprising.
Insurance coverage, benefits and claim amounts vary by insurer, policy and individual circumstances. Always refer to your policy documents or check directly with your insurer or financial adviser for details specific to your coverage.
Know your coverage, before you need it
Before you need care, take time to check your coverage. It may make a meaningful difference to what you eventually pay.
