How to Get Insurance in Singapore With a Pre-Existing Medical Condition

Insurance is always best bought when you’re young, when the odds of a clean bill of health are highest and you can get the full extent of coverage.

But plenty of people treat it as something they can put off. And it’s true that the chances of a critical illness or death rise with age.

There are two things worth remembering, though.

First, these events can still happen early, and when they do, they tend to hit your family’s finances harder. Second, even a minor condition picked up along the way can affect your chances of being approved later.

So if you already have a pre-existing condition and you’re wondering what your options are, you’re not out of luck. We can’t turn back the clock, but here’s what you can still do.

Key Takeaways

• Every Singapore citizen and PR is covered by MediShield Life for life, including for pre-existing conditions. Serious conditions carry 30% higher premiums for the first 10 years.
• Private insurers underwrite pre-existing conditions case by case. An application lands on one of five outcomes: accept, exclude, load, postpone, or reject.
• Underwriting appetites differ between insurers, so the same condition can be accepted by one and declined by another. Applying to a few can pay off.
• Anyone who has served National Service can get up to $300,000 of death and total permanent disability cover with no medical underwriting through the MINDEF and MHA Voluntary Scheme.
• Never leave a condition off the health questionnaire. Non-disclosure can lead to rejected claims or a voided policy.

What Is a Pre-Existing Medical Condition?

A pre-existing medical condition is an injury, illness, or disease that you have before you apply for insurance.

Sounds broad? It is. But not all conditions are treated equally.

If you’ve seen the doctor for the odd cold, cough, or fever, those usually don’t matter much to an insurer.

What they pay attention to are conditions that are chronic or have a longer-term impact on your health. Common examples include:

• Asthma
• Cancer
• Stroke
• High cholesterol
• High blood pressure
• High blood sugar
• High BMI

Even if you’ve recovered, it can still count as a pre-existing condition.

So how do you know whether what you have is material to the insurer? When you apply, there’s usually a health questionnaire to fill in. Some plans ask for a lot of detail, others just a few simple questions. Your job is to answer them truthfully.

What Happens If You Don’t Declare Pre-Existing Conditions?

If you don’t declare a pre-existing condition, the insurer can reject a claim linked to it at the very moment you need it, and can even void the contract entirely for the lack of full and accurate disclosure. These cases aren’t rare, and they make the news from time to time.

You already know why insurance matters.

Medical costs keep climbing, a serious hospital bill (think cancer treatment) can run into six figures, and the cost of living isn’t getting any kinder. Cover that shields your income from a large medical bill is worth having.

Here’s the hard truth: people with medical conditions may not get the full coverage they want. Which is exactly why some are tempted to leave a condition off the form.

As we said, different types of insurance call for different levels of medical underwriting. Either way, you should always answer the health questionnaire fully and accurately. The whole point of insurance is being able to claim when something goes wrong, and non-disclosure leaves you with a policy that does nothing.

There’s a quieter cost too. Not declaring everything, while knowing a claim might not be paid, can leave you carrying needless worry for years.

This is why it’s better to declare everything upfront. That way you know, there and then, whether you’re fully covered. And because conditions leave a paper trail (GP visits, hospital records), they rarely stay hidden anyway.

What insurers want is the full picture so they can make a fair decision. They aren’t looking to deny cover for no reason.

What Happens After You Declare Your Medical Conditions?

Once you’ve declared your medical conditions, the insurer’s underwriters assess your application, and it usually lands on one of five outcomes: accepted on standard terms, accepted with an exclusion, accepted with a premium loading, postponed, or rejected.

There isn’t much left for you to do at this stage. Depending on the plan, the insurer may ask for more: medical reports, or a referral for a medical check-up, for example.

Because insurers have different underwriting standards, or different appetites for risk, it can pay to apply to a few. There are cases where the same person is accepted by one insurer and declined by another.

Here’s what each outcome means.

1) Accept

When a policy is accepted on standard terms, it’s no different from cover for someone with no medical conditions. If you later claim because of a condition you had, the insurer should still pay, subject to the policy terms. These cases tend to happen when the underwriters see the condition as lower-impact or a risk they’re happy to take.

2) Exclude

When a condition is more serious, that condition (and anything related to it) is often excluded. So if something happens because of it, there’s no payout, though unrelated claims can still go through. The exact terms are spelled out to you before you decide whether to accept.

3) Load

A loading means higher premiums. You’ll be told how much more, and it can be 30%, 100%, or even 200% above the standard rate, depending on the severity of your condition. In return, your condition stays covered and can be claimed for.

4) Postpone

An insurer usually postpones when there isn’t enough information to decide. Say you’d recently seen a specialist about protein in your urine with no firm diagnosis yet. There’s nothing conclusive to underwrite, so they may postpone for a period (say a year), after which you can reapply with fresh medical reports.

5) Reject

In the worst case, the application is turned down outright.

Even then, you can appeal, though you’d need to come back with more compelling medical evidence.

What Options Are There for Those With Existing Health Conditions?

In my opinion, the regular plans built for the mass market tend to offer the best coverage at the lowest price. That means your standard term insurance, early critical illness plans, or whole life insurance.

So those should be your first port of call.

But if you’ve already applied and the terms weren’t in your favour, here are some other options to weigh up.

1) MediShield Life

Medical insurance is one of the most basic building blocks of a sound financial plan.

Every Singapore citizen and permanent resident is covered by MediShield Life, a national health insurance scheme that protects against large hospital bills and selected costly outpatient treatments such as kidney dialysis and cancer chemotherapy.

Its big advantage here is simple: it covers pre-existing conditions, whether minor or serious.

If your condition is one of the serious ones, you pay 30% higher premiums for the first 10 years, after which you’re back on the same rates as everyone in your age group. That structure is set out by the Ministry of Health, whose list of serious pre-existing conditions includes:

1. Cancer
2. Blood disorders
3. Degenerative diseases
4. Heart or other circulatory system diseases
5. Cerebrovascular diseases
6. Respiratory diseases
7. Liver diseases
8. Autoimmune or immune system diseases
9. Renal diseases
10. Serious congenital conditions
11. Psychiatric conditions
12. Chronic conditions with serious complications

The trade-off is that MediShield Life is sized for subsidised B2 and C wards in public hospitals. If you want to be treated in an A ward or a private hospital, expect to pay a lot more out of pocket.

Think of it as the floor that’s always there, even if everything else falls through.

2) Integrated Shield Plan

As the name suggests, the Integrated Shield Plan (IP) is built on top of MediShield Life. It adds enhanced cover, including private hospitals, on top of what the national scheme provides. For many Singaporeans, MediShield Life plus an IP is one of the strongest medical insurance setups available.

Seven insurers currently offer IPs: AIA, Great Eastern, HSBC Life, Income Insurance, Prudential, Raffles Health Insurance, and Singlife. If you last checked this list a while ago, two names have changed: AXA’s health business is now under HSBC Life, and Singlife has dropped the Aviva branding.

Here’s the part that matters if you have a pre-existing condition. On the private component of an IP, a pre-existing condition isn’t automatically covered. What happens next comes down to each insurer’s underwriting, and it lands on the same outcomes as any other application: it might be excluded, or accepted with a premium loading. Some insurers lean towards exclusion.

That’s why it’s worth applying to more than one insurer, because appetites differ. Some insurers have even started offering options to cover selected pre-existing conditions in return for a higher premium, rather than excluding them outright. It’s assessed by underwriting at application, and the exact conditions eligible differ from insurer to insurer.

One more thing worth knowing: whatever the private insurer decides about your condition, the MediShield Life layer sitting inside every IP still covers it for life. So even an exclusion on the private side doesn’t strip away that base protection.

Separately, the rules on IP riders (the add-ons that reduce your out-of-pocket share) changed in 2026, though that reform is about deductibles and co-payments rather than pre-existing conditions. We cover it in full in our guide to the new IP rider changes.

3) The MINDEF and MHA group scheme

If you’ve served National Service, you have access to a route many people forget about. The MINDEF and MHA group insurance, underwritten by Singlife, includes a Voluntary Scheme you can top up and keep after your service ends. This is separate from the free Core Scheme, which only covers you while you’re serving (as an NSF, an eligible NSman, a regular, or an eligible volunteer) and pays $350,000 each for group term life and personal injury since 1 November 2025.

Why it matters here: under the Voluntary Scheme, the insurer accepts Group Term Life cover (death and total permanent disability) of up to $300,000 with no medical underwriting. Anything above that is underwritten as usual. If your health isn’t perfect, locking in that much cover without a health assessment is a big deal.

There are two catches to be clear about, though.

No underwriting doesn’t mean a pre-existing condition is simply ignored. On the non-underwritten cover, a death or TPD claim caused by a condition you already had is only payable once you’ve held the cover continuously for 12 months. After that, it’s covered.

And the scheme’s critical illness riders (Living Care, covering 37 severe-stage conditions, and Living Care Plus, covering 10 early-stage conditions) are separately underwritten. So on the critical illness side, imperfect health can still mean an exclusion, a loading, or a straight decline, the same as any other plan. No shortcut there. If critical illness cover is your main concern, our overview of critical illness in Singapore is a useful starting point.

The scheme is open to you, and to your spouse and children, at the same low group rates. It won’t solve everything, but for the death and TPD portion it’s one of the more accessible routes if your health has made regular plans difficult.

4) Specialised Life Insurance Plans

As with smokers, a serious medical condition usually means higher premiums for life insurance.

But if you find yourself declined, or quoted premiums that feel out of reach, on the regular life and critical illness plans, there are still specialised options.

Some insurers offer plans that cover people with type 2 diabetes, pre-diabetes, high cholesterol, high blood pressure, or a high BMI. There are also plans built for people who have already been diagnosed with cancer.

These are less common and come with reduced coverage compared with a standard life plan, but they can still be worth having, especially if you see insurance as essential.

5) Self-Insure

Sometimes there’s no workable alternative. You’ve been declined, or the premiums are simply too high.

The last resort is to self-insure.

In practice, that means building a pool of savings set aside to absorb a future financial “loss” that insurance would otherwise have covered.

It makes sense on paper, but it isn’t foolproof. You might not have saved enough by the time something happens, or the loss could be too large to absorb. Which, ironically, is the whole reason insurance exists, and why it’s always smart to get covered while your health is good. When you need it most, you may not be able to get it.

Wrapping Up

Whether you can get insured with a pre-existing condition really depends on how serious it is. Sometimes it’s a hit, sometimes a miss.

The least you can do is apply to a few insurers and see what comes back. Different underwriters, different answers, and at least you’ll know where you stand.

You’re also welcome to go through a comprehensive financial planning session with us to weigh up your options together.

And if you know someone who still hasn’t got any cover, it’s worth passing this on, so they understand both why it matters and how much harder it gets once a condition shows up.
