On 7 October 2026, Deputy Prime Minister and MAS chairman Gan Kim Yong said in a written parliamentary reply that the Life Insurance Association, Singapore (LIA) will review its severe stage critical illness definitions from 2027. The review will look at whether some conditions can rely less on a named operation and more on the disease itself and how severe it is. This post answers what that means for the critical illness (CI) policy you already hold, why some definitions hinge on a procedure, and what happens next.
The reply answered a question from Dr Hamid Razak, MP for West Coast-Jurong West GRC. He asked whether MAS would engage the LIA on tying CI definitions to the underlying disease and its severity instead of a specific surgical procedure, so that people do not lose cover only because doctors chose a different treatment. Mothership reported that he is a practising orthopaedic surgeon.
Gan's answer, published on the MAS website, made these points:
A severe stage CI policy pays a fixed lump sum when you are diagnosed with an advanced stage illness or have a specified major procedure. Gan said the payout is there to help with the financial impact of a serious illness, and it does not reimburse the cost of treatment. MediShield Life works differently: it pays for medically necessary treatments and surgical procedures on the Ministry of Health's Table of Surgical Procedures, which MOH updates regularly.
Because the CI payout is not tied to a bill, Gan said some definitions name an established procedure as an objective marker. The procedure stands for how severe the disease is, how long recovery takes and the money impact that follows.
The current standard is the LIA Critical Illness Framework 2024, which sets definitions for 37 critical illnesses. The LIA lists it as effective no later than 1 October 2025.

Mothership reported the reply alongside a court case. In 2023, a woman had a stroke from a ruptured brain aneurysm and was given an emergency endovascular repair, a minimally invasive procedure, at the National University Hospital. Her early critical illness policy, bought in 2016, covered brain aneurysm surgery only when it was done as a surgical craniotomy, which opens the skull. Her insurer denied the claim.
She sued in March 2026 for S$108,500 plus a waiver of premiums, and represented herself. She argued that she had no say in which operation was done, as she was unconscious in intensive care, and that the exclusion was not explained to her when she bought the policy.
District Judge Teo Guan Kee dismissed the claim in a written judgment published on 3 September 2026. He found that she had received and initialled the product summary, and that she had been given 14 days to review the policy and ask to cancel it. She told Mothership she would most likely appeal.

No. Gan said updated definitions will apply to new products sold. In an earlier written reply on 7 May 2026, to a question from Gerald Giam, MP for Aljunied GRC, he said existing policies do not assume the updated LIA definitions.
He gave the reason. Newer definitions and procedures could widen what a policy covers and lead to more claims, and doing that without a matching premium increase could affect whether the product stays sustainable.
In the same reply, Gan said the LIA is studying whether people with existing CI policies could adjust their cover to include newer treatments, with premiums adjusted to match. He said the study will take time because of its actuarial implications.
| Your situation | Definitions that apply | MAS reply |
|---|---|---|
| A CI policy already in force | The wording in your contract; later LIA updates are not assumed | 7 May 2026 |
| A new severe stage CI policy | The LIA's latest definitions, which insurers adopt for new policies | 7 May 2026 |
| Products sold after the 2027 review | Any updated definitions that come out of that review | 7 October 2026 |
Gan said the LIA will explore in its 2027 review whether definitions for certain conditions can shift towards the disease and its severity, and that any change needs careful consideration.
On premiums, he said any change would alter what these policies cover and their claims experience. That feeds into what they cost, since premiums depend on the probability of claims.
In May, Gan encouraged consumers to review the type, coverage and affordability of their health insurance regularly as their needs change. These are the points the two replies and the court case raise:
The next review starts in 2027. Deputy Prime Minister Gan Kim Yong gave the date in a written parliamentary reply on 7 October 2026, published on the MAS website.
No. Gan said updated definitions will apply to new products sold, and in May 2026 he said existing policies do not assume updated LIA definitions. The LIA is studying whether existing policyholders could adjust their cover, with premiums adjusted to match.
The LIA will look at whether definitions for certain conditions can rely less on specified procedures in its review starting in 2027. Gan said any change needs careful consideration because it affects the scope of coverage, claims experience and premiums.
A district judge dismissed the S$108,500 claim in a judgment published on 3 September 2026. The policy covered brain aneurysm surgery only as a craniotomy, and the policyholder had an endovascular repair. She said she would most likely appeal.
