A 45-year-old woman has lost her lawsuit against Prudential Assurance Company Singapore over a S$108,500 insurance payout for treatment following a ruptured brain aneurysm.
In a judgment dated 3 September 2026, District Judge Teo Guan Kee dismissed Ms Cai Yanhong's claim, finding that her policy did not cover the type of procedure she underwent and rejecting her argument that the relevant definition had effectively been hidden in the policy documents.
Ms Cai told CNA after the judgment that she would likely appeal the decision.
She Underwent Emergency Surgery After A Brain Aneurysm Ruptured
Ms Cai bought a PruLife Multiplier life insurance policy in August 2016 through a bancassurance channel operated by Standard Chartered Bank. One of its benefits was the Early Crisis Cover Multiplier.
On 8 April 2023, she suffered a ruptured brain aneurysm while on a bus and was taken to the National University Hospital.
She underwent an endovascular repair, a procedure performed through blood vessels rather than by opening the skull. According to CNA, she spent 21 days in hospital, including eight days in intensive care.
Ms Cai subsequently made a claim under her insurance policy, but Prudential rejected it in September 2023.
The dispute centred on how the policy defined "brain aneurysm surgery".
Under the policy, coverage for brain aneurysm surgery required the patient to actually undergo a surgical craniotomy. A craniotomy involves temporarily removing part of the skull so doctors can access the brain.
The policy also expressly stated that endovascular repair or procedures were not covered.
Ms Cai sought S$108,500 under the Early Crisis Cover Multiplier, along with interest. She also sought a refund of premiums paid in 2023 and 2024 and a waiver of future premiums, benefits worth about another S$12,000.
Judge Rejects Argument That Clause Was Buried
Ms Cai argued that the restriction had been buried in the policy and that "brain aneurysm surgery" appeared in an earlier section without sufficient warning that a specific surgical technique was required.
But Judge Teo found that this was not a fair description of the policy documents.
The judgment noted that the section listing covered conditions directed readers to another section containing their definitions. That section specifically stated that endovascular repair was excluded from the definition of brain aneurysm surgery.
The judge found that, when the policy was read as a whole, there was no uncertainty that the Early Crisis Cover Multiplier would not apply when an insured person underwent an endovascular procedure instead of the required craniotomy.
The court also examined whether the restriction had been properly brought to Ms Cai's attention.
Documents showed that she had acknowledged receiving the relevant product summary and that its contents had been explained to her satisfaction. Before purchasing the policy, copies of the documents had also been emailed to her, including a reference directing her to the section containing definitions of the covered critical illnesses.
After receiving the final policy, she also had 14 days to review its terms and ask for the policy to be cancelled.
The judge stressed that the ruling did not make any finding about whether Standard Chartered or its employees owed Ms Cai any separate duty or liability, as they were not parties to the lawsuit.
Prudential Says Some Newer Policies Cover The Procedure
Prudential told CNA that insurers had differing approaches towards endovascular repair when Ms Cai bought her policy in 2016.
The insurer also said some of its current critical illness policies now cover endovascular procedures, including a plan launched in March 2026.
Following the judgment, Prudential said Ms Cai's claim had been assessed according to the terms of the policy she bought about 10 years ago. The company said it would also consider waiving any court-ordered costs that Ms Cai might otherwise have to pay Prudential as a gesture of goodwill.
The court has not yet fixed the costs of the lawsuit.
As of the latest CNA report on 3 September, Ms Cai had said she was likely to appeal, but no appeal had yet been reported as filed.
