Singapore Medical Insurance Explained: An Interactive Guide

Singapore’s hospital insurance is structured in three layers, each building on the one below.

MediShield Life is the foundation — a compulsory government scheme run by the CPF Board covering every Singapore Citizen and Permanent Resident for life. It covers inpatient treatment at Class B2 and C ward rates in public hospitals, with a claim limit of $200,000 per year and no lifetime cap. Premiums are fully payable from MediSave.

Integrated Shield Plan (IP) is a private insurance layer offered by seven MOH-approved insurers. It integrates MediShield Life into a single policy and extends coverage to higher ward classes — Public A, or Private Hospital — with policy year limits ranging from $200,000 to $2.5 million depending on the plan. IP premiums are partially payable from MediSave.

Rider is an optional add-on that attaches to your IP main policy. It reduces your out-of-pocket exposure by covering part of the deductible (for legacy policies) and co-insurance. All rider premiums must be paid in cash — they are not MediSave-approved.

MOH defines four coverage tiers for Integrated Shield Plans:

Standard B1 is the entry-level tier, covering Class B1 wards in public hospitals. Benefits are identical across all seven insurers — MOH mandates the coverage structure. Only premiums differ between insurers at this tier.

Class B1 covers the same Class B1 wards but with higher policy year limits and typically “As Charged” benefits with no sub-limits on surgical fees. Unlike Standard B1, coverage terms and premiums vary between insurers. This tier suits those who want more headroom than the standardized plan without stepping up to a Class A plan.

Public A covers Class A wards in public hospitals (single-bedded, air-conditioned), with your choice of specialist. Policy year limits are significantly higher than B1 plans, and most plans offer “As Charged” benefits across all benefit categories.

Private Hospital is the highest tier, covering private hospital rooms and unrestricted specialist choice. Most plans at this tier are “As Charged” across all benefit categories, with policy year limits typically between $1 million and $2.5 million.

Note: all tiers also include MediShield Life, which continues to cover Class B2/C treatment — so even a Private Hospital plan provides coverage if you choose a subsidised ward.

There are exactly seven MOH-approved insurers offering Integrated Shield Plans in Singapore: AIA, Income, Great Eastern, Prudential, Singlife, HSBC Life, and Raffles Health Insurance. Each insurer offers plans across the same coverage tiers (Standard B1, Public A, and Private Hospital), but they differ in policy year limits, specific benefit sub-limits, panel doctor networks, and premium pricing. You can only hold one IP at a time.

Inpatient benefits apply when you are admitted to hospital:

• Daily ward and treatment charges (room, nursing, in-hospital specialist consultations)
• Surgical fees (surgeon, anaesthetist, operating theatre)
• Implants used during surgery (stents, prostheses, pacemakers, cochlear implants)
• Radiosurgery (Gamma Knife, CyberKnife, Proton Beam Therapy Category 4)
• Pre-hospitalisation treatment within the covered period (scans, specialist referrals, blood tests)
• Post-hospitalisation follow-up care within the covered period

Outpatient benefits apply without requiring a hospitalisation:

• Cancer drug treatment — chemotherapy, targeted therapy (e.g. Herceptin), immunotherapy (e.g. Keytruda), hormone therapy
• Radiotherapy — external beam, IMRT, brachytherapy, Proton Beam Therapy Categories 1–3
• Kidney dialysis (haemodialysis and peritoneal dialysis)
• Immunosuppressants for post-transplant patients

Before your insurer pays, two cost-sharing mechanisms apply to every inpatient claim:

Deductible is the first amount you pay before insurance coverage begins — once per policy year, regardless of how many hospitalisations you have. The amount depends on ward class: $1,500 for Class C, $2,000 for Class B2, $2,500 for Class B1, and $3,500 for Class A or private hospital. If you’re admitted twice in the same policy year, you only pay the deductible once.

Co-insurance is the percentage of the remaining bill you share with your insurer after the deductible. The standard rate is 10% — your insurer pays 90%, you pay 10%. On a $50,000 bill with a $3,500 deductible, you’d pay $3,500 + 10% of $46,500 = $8,150 out of pocket before any rider.

A co-payment rider reduces or caps the co-insurance portion. From April 2026, new riders cap your annual co-insurance at $6,000 for panel providers.

There are three main types of IP riders:

Co-payment riders are the most common. They reduce the deductible and co-insurance you pay on inpatient claims. Under pre-April 2026 riders, the deductible could be fully covered; under new riders sold from April 2026, you must pay the deductible yourself, but the rider caps your annual co-insurance at $6,000 for panel providers.

Cancer riders cover outpatient cancer treatments — chemotherapy, targeted therapy, and immunotherapy — that fall outside the standard pre/post-hospitalisation windows. This is particularly valuable as cancer treatment is typically ongoing and expensive.

Emergency overseas riders extend your IP coverage for hospitalisation while travelling abroad, up to specified limits. Benefits and claim procedures vary significantly by insurer.

MOH has revised IP rider rules twice since 2019, progressively tightening cost-sharing requirements:

Pre-November 2019: Riders could fully cover both the deductible and co-insurance, resulting in zero out-of-pocket costs for policyholders. This led to overconsumption concerns and was phased out.

November 2019 – March 2026: Riders could still cover the deductible, but a minimum 5% co-payment was required. For panel providers, the annual co-insurance exposure was capped at $3,000 per year.

From April 2026 (new riders): Riders can no longer cover the deductible — you must pay it yourself, though MediSave can be used. The minimum 5% co-payment requirement remains unchanged. The annual co-insurance cap for panel providers is raised to $6,000. MOH estimates new private hospital rider premiums will be approximately 30% lower than existing maximum-coverage riders. Policyholders who purchased old riders on or after 27 November 2025 must transition to the new design no later than their first renewal after 1 April 2028; for policyholders who held riders before that date, individual insurers determine the transition approach.

Under the pre-2026 regime, a comprehensive rider could eliminate nearly all out-of-pocket costs. From April 2026, that changes: you always pay the deductible yourself, and even with a rider, a minimum 5% co-insurance applies on every claim. For small to mid-sized bills, this means a meaningful minimum out-of-pocket regardless of your rider. Riders now make the most difference on large bills — where the 5% co-insurance adds up — with the $6,000 annual cap on co-insurance for panel providers providing the real catastrophic protection.
