Deductibles and co-insurance on a Shield plan, worked through with numbers
An Integrated Shield Plan does not pay every dollar of a hospital bill. Deductible and co-insurance decide your share, and the gap between ward classes is large.
Two terms decide how much of a hospital bill you actually pay under an Integrated Shield Plan (IP): the deductible and co-insurance. Both are explained in every product summary, but they are easy to skim past until a real bill arrives. Working through an actual example makes the gap between "insured" and "fully covered" much clearer.
The two pieces
The deductible is the fixed amount you pay yourself, out of that policy year's claim, before your IP starts paying anything at all. It resets each policy year and is not a one-off. Under most IPs it ranges from roughly $1,500 to $3,500 a year, depending on the ward class you are covered for — the higher the ward class or private hospital cover, the higher the deductible tends to be.
Co-insurance is the share of the bill you continue to pay after the deductible has been cleared, expressed as a percentage — commonly 5% of the remaining claimable amount. It is not a flat fee; it moves with the size of the bill. Some plans cap co-insurance at a stated minimum per year (for example, a floor of around $6,000), meaning that even a very large claim will not force your co-insurance liability below that amount for the year, but it caps how much further co-insurance can climb beyond that floor in practice for most claims.
A rider can be added to cover most or all of the co-insurance portion, in exchange for its own separate premium, which must be paid in cash rather than MediSave. Riders do not remove the deductible.
A worked example
Take a heart bypass, a real-world example CPF Board has used to illustrate how ward choice changes what a patient pays. Bill amounts vary by hospital and ward, but the shape of the comparison holds:
| Ward stay | Illustrative hospital bill | Roughly what the patient pays |
|---|---|---|
| Subsidised C | ~$6,400 | ~$2,000 |
| Subsidised B2 | ~$8,300 | ~$2,500 |
| Unsubsidised B1 | ~$36,100 | ~$5,900 |
| Unsubsidised A | ~$39,500 | ~$7,100 |
| Private hospital | ~$83,500 | ~$11,500 |
These figures assume the patient holds an IP matched to the ward they actually stayed in and is below age 81; actual amounts vary by insurer and change over time, so treat them as illustrative rather than a quote. The pattern is the point: choosing a private hospital or an unsubsidised ward does not just mean a bigger bill — it means a bigger deductible, a bigger co-insurance base, and a patient share that can run four to five times higher than the subsidised-ward equivalent, even with equivalent IP cover for that tier.
Where the deductible and co-insurance actually apply
Both apply per policy year, not per claim — so multiple admissions or treatments within the same year draw down against the same deductible once it has been met, which is worth knowing if you expect more than one procedure within twelve months. They also apply on top of, not instead of, MediShield Life's own claim limits: MediShield Life pays first up to its scheme limits, and the IP's private component, deductible and co-insurance sit on top of that base layer.
Why this shapes your ward choice, not just your premium
It is tempting to think of ward class purely as a premium decision — a higher ward class costs more each month. The worked example above shows the other side: it also raises what you pay at the point of claim, through both a higher deductible and a co-insurance percentage applied to a larger bill. A plan that looks only modestly more expensive in monthly premium can carry a materially larger out-of-pocket exposure if you are ever admitted and use it.
Questions worth asking before choosing a tier
- What is the deductible for the ward class I am actually likely to use, not the one I am buying cover for in theory?
- Is there a rider available to cover co-insurance, and what does it cost in cash each year?
- Does the deductible reset annually, and does more than one admission in a year draw down the same deductible?
- How does the insurer define "reasonable and customary" charges for calculating co-insurance, and where can I see that definition?
- If I downgrade my ward class later to manage premiums, does my deductible change immediately or only at renewal?
Our coverage gap check can help you see how a given deductible and co-insurance structure compares with your savings buffer, and comparing plans side by side makes the deductible tiers easier to line up than reading each product summary separately.
Talk to an advisor
The right combination of ward class, deductible and rider depends on how much of a bill you could comfortably absorb yourself in a bad year, which is a personal number rather than a product feature. An advisor can run the numbers for your specific plan and household. Use the portal's advisor matching to find one, or ask our assistant to explain a specific figure on your policy summary.
