Critical illness insurance in Singapore: what it pays and how much cover you need

Critical illness insurance in Singapore pays you a lump sum when you're diagnosed with an illness your policy covers, such as a major cancer or a heart attack. It's separate from MediShield Life and Shield plans, which pay part of your hospital bill. MoneySense's rule of thumb is cover of 4 times your annual income. Check the definitions and waiting period before you sign.

How to choose critical illness insurance, step by step

1. List the cover you already have, and count anything from your job. CPF notes that medical benefits from an employer stop once you leave the company. Our guide to insurance for new parents lays out the whole family picture.
2. Set a target with MoneySense's rule of thumb: critical illness cover of 4 times your annual income. Run the sum for each parent who earns.
3. Cap your spending. MoneySense suggests at most 15% of your income on all your protection together, not on this plan alone.
4. Pick a standalone plan or a rider. LIA says critical illness cover is sold on its own or as a rider attached to a whole life or term plan.
5. Ask whether a rider accelerates your life plan. If it does, MoneySense says the policy may end once the rider pays out, and its life cover goes with it.
6. Read the list of illnesses in the Product Summary. LIA requires insurers to list them there and to mark the ones that use LIA's standard definitions.
7. Check how earlier stages are defined. LIA sets definitions only for the severe stage of 37 illnesses, so each insurer writes its own for earlier stages.
8. Find the waiting period and any survival period. MoneySense says nothing is paid for an illness diagnosed in the waiting period. Where a plan has a survival period, LIA's guide says it can be 7, 14 or 30 days after diagnosis.
9. Declare every health condition on the application. MoneySense says the insurer then decides whether to cover it, and may charge a higher premium, called a loading.
10. Compare plans side by side on compareFIRST. Then read your policy during the free-look period, which MoneySense says is at least 14 days from when you receive it.

What it pays, and what your Shield plan pays

MoneySense says critical illness insurance pays a one-time lump sum if you're diagnosed with a covered illness, or after a covered type of surgery. The amount doesn't depend on your medical bills. CPF notes you can spend it however you need, such as on care costs.

Your hospital bill is a separate matter. LIA says hospital bills are covered by a hospitalisation and surgical plan, and a lump sum on diagnosis needs a critical illness plan. Our guide to hospitalisation insurance for families covers that side.

CPF describes CareShield Life as a long-term care insurance scheme. It pays monthly cash once an MOH-accredited assessor finds you can't do 3 of the 6 activities of daily living, such as washing or dressing.

Types of critical illness plans

LIA keeps standard definitions for the severe stage of 37 illnesses. The current set is Version 2024, and since 1 October 2025 plans using the older Version 2019 definitions can't be sold. LIA's FAQ, citing reinsurance research, says five illnesses make up close to 90 per cent of severe-stage claims: major cancers, heart attack, stroke, other heart diseases and kidney failure.

Plans also differ in what they list. LIA's guide says some go past the standard 37 to juvenile conditions, diabetic complications or gender-specific conditions.

How much critical illness cover a parent needs

MoneySense's guide for parents aged 35 to 59 sets the rule of thumb at critical illness cover of 4 times your annual income, and caps what you spend on all protection at 15% of income.

Say you earn $60,000 a year; this is an example. That gives 4 x $60,000 = $240,000 of critical illness cover, while the spending cap works out to 15% x $60,000 = $9,000 a year across every policy you hold.

Take away critical illness cover you already own, such as a rider on an older policy. Life cover has its own rule of 9 times income, which our life insurance guide for parents works through. If both of you earn, run the sums on each income.

If one of you stops work, cover from that job stops too. Our stay-at-home mum guide covers the rest of that change. CPF suggests reviewing your policies every 3 to 5 years as your life changes. Keep the list in our new parent money checklist.

Exclusions and conditions to check

MoneySense says private health insurance usually excludes pre-existing conditions. CPF names diabetes, high blood pressure and high cholesterol as conditions many policies don't cover. A claim is paid only if the illness meets the definition in your policy.

Each insurer now sets its own waiting periods. LIA dropped the industry's standard 90-day waiting period in November 2022, so read the figure in your own policy.

If your cover is a rider, LIA's guide says to check whether you pay premiums for life or for a limited time. On a limited basis, premiums stop after a set period and the cover carries on.

MoneySense says it may be costly to end and replace a product in its early years. A new policy may also not cover health conditions you've developed since you bought the old one.

Cover for your child and your own parents

Some critical illness plans are designed for children. LIA's FAQ says these cover conditions outside the standard 37, and LIA's guide mentions plans that extend to juvenile conditions. For what your baby already gets from MediShield Life, see our newborn insurance guide.

For your own parents, MoneySense says private plans may have an age limit. If they're citizens or PRs, MediShield Life has no age limit and covers them for life. For anyone born in 1979 or earlier, CPF says joining CareShield Life is optional.

A Lasting Power of Attorney names who decides for you while you're alive; our will and guardianship guide explains it. If money runs short during treatment, our guide to financial help for families shows where to start.

Where to get help

• Compare plans on compareFIRST: search term life or whole life plans and set Critical Illness Benefit to Yes.
• Check who is advising you on MAS's Financial Institution Representatives Register.
• Disagree with a claim decision? LIA says to lodge a formal appeal with the insurer first. If you're still unhappy, go to FIDReC, which says filing a dispute is free.
• Read what SDIC's Policy Owners' Protection Scheme covers if a member insurer fails.
• Ask CPF about CareShield Life and how to make a claim.

Frequently asked questions

Do I need critical illness insurance in Singapore if I have a Shield plan?

They pay for different things. A Shield plan pays part of your hospital bill, while critical illness insurance pays a lump sum on diagnosis, whatever the bill. LIA notes that a Shield plan doesn't give you that lump sum. The choice is yours, and MoneySense's 4 times income gives you a starting figure.

Critical illness vs hospitalisation insurance: what's the difference?

Hospitalisation insurance, such as MediShield Life or a Shield plan, pays part of an inpatient bill. Critical illness insurance pays a fixed sum when you're diagnosed with a covered illness. MoneySense says that amount doesn't depend on your medical expenses. You can hold both.

How much critical illness cover do I need?

MoneySense's rule of thumb is 4 times your annual income. On an example income of $60,000, that's $240,000. Take away cover you already own, and keep all your protection within 15% of your income.

What is early critical illness cover?

It pays at an earlier stage than the severe stage LIA defines. LIA leaves those earlier definitions to each insurer, so read them in the policy. MoneySense says some plans pay a smaller amount for earlier stages of cancer.

Can I buy critical illness insurance for parents who are older?

It depends on the insurer's age limit and your parent's health. MoneySense says private plans may have an age limit and usually exclude pre-existing conditions. If they're citizens or PRs, MediShield Life still covers them for life, pre-existing conditions included.

Does my old critical illness policy use LIA's new definitions?

No. LIA's FAQ says claims follow the definitions in the policy contract you hold. Version 2024 applies to plans sold from 1 October 2025. MoneySense says ending a product in its early years may be costly.
