Integrated Shield Plans in Singapore, compared: what each tier actually covers

An Integrated Shield Plan is MediShield Life plus a private top-up, sold as one policy and paid partly from MediSave. Around two-thirds of residents hold one. The plans look alike on a brochure and behave very differently on a hospital bill. This entry sets out how the tiers are built, what the riders do, and how to pick a tier by the ward you would genuinely choose.

How an Integrated Shield Plan is built

Every plan has two layers. The bottom layer is MediShield Life, run by the Central Provident Fund Board, which every citizen and permanent resident has regardless of insurer. The top layer is the private insurer’s additional cover, which raises the claim limits and extends cover to higher ward classes and private hospitals.

When you claim, the bill is split: MediShield Life pays its share first, the insurer pays the rest up to the plan’s limits, and you pay the deductible and co-insurance. The insurer administers the whole claim; you do not deal with CPF Board separately.

The tiers, and what they are sized for

Insurers name tiers differently, but they map to ward class.

Tier	Sized for	Typical use
Standard plan	Public hospital B1 ward	Regulated, identical across insurers
B1 plan	Public hospital B1 ward	Four-bed, air-conditioned, choice of doctor
A plan	Public hospital A ward	Single or two-bed, public hospital
Private plan	Private hospitals	Any private hospital, standard room

Choosing a lower ward than your plan covers is allowed and the plan pays in full. Choosing a higher ward than your plan covers triggers pro-ration: the insurer pays the percentage of the bill that the lower ward would have cost, and you pay the rest.

The seven insurers

The Integrated Shield Plan market has seven providers licensed by the Ministry of Health: AIA, Great Eastern, HSBC Life, Income, Prudential, Raffles Health Insurance and Singlife. Each offers a Standard plan and a ladder from B1 to private. The differences that matter on a claim are:

Panel doctors. Most insurers now maintain a panel of private specialists. Using a panel doctor gives you pre-authorisation, a higher rider claim limit, and sometimes a lower co-payment. Using a non-panel doctor at a private hospital is still covered but with a lower cap on what the rider pays.

Pre-authorisation. Insurers offer a letter of guarantee before admission if the treatment is pre-approved. Without it, you pay first and claim after.

Claim limits on the private tier. Annual limits range roughly from S$600,000 to S$2,000,000 depending on insurer and year; check the current policy document rather than any comparison table, including this one.

Riders, and the 2018 co-payment rule

The base plan has a deductible — an amount you pay each policy year before the plan pays anything — and co-insurance of around ten percent on the rest. Riders were sold to remove both. Since 2018, new riders must leave the policyholder paying at least five percent of the bill, usually capped at around S$3,000 a year if you use a panel doctor and pre-authorisation. Riders bought before the rule change were required to move to a co-payment structure by 2021.

Riders are paid in cash, not MediSave. On the private tier, the rider premium at older ages can exceed the base plan premium.

Premiums and how MediSave pays

Base plan premiums are paid from MediSave up to an Additional Withdrawal Limit set by age band — a few hundred dollars a year for people under forty, rising in steps for older bands. Anything above the limit, and the whole rider, is paid in cash. Premiums rise with age at every insurer; the jump after sixty-five is steep on the private tier.

The Standard plan is the one regulated, insurer-neutral option: same benefits everywhere, priced within MediSave limits for most ages, sized for B1 wards. It exists so that nobody is forced into cash premiums to keep B1 cover.

Matching a tier to the ward you would use

Ask which ward you would actually choose if admitted tomorrow. If the answer is a subsidised B2 or C ward, MediShield Life alone is sized for it and an Integrated Shield Plan adds little. If it is B1, the Standard plan or a B1 plan does the job at MediSave-only premiums for most ages. If it is a single room at a private hospital, only the private tier with a rider makes the bill manageable, and the cash premium is the price of that choice.

Downgrading later is easy and cheap. Upgrading later means new underwriting, and any condition diagnosed in between is excluded.

Claims in practice

Public hospital bills are submitted electronically by the hospital; you sign a claim authorisation at admission. Private hospitals do the same for most insurers, but with a letter of guarantee the hospital bills the insurer directly rather than asking you for a deposit. Outpatient cancer treatment, kidney dialysis and some pre- and post-hospitalisation care are claimable under most plans within stated windows, typically ninety days before and up to a year after admission on the private tier.

Frequently asked questions

Do I need an Integrated Shield Plan if I already have MediShield Life?

Only if you would choose a B1 ward or above, or a private hospital. MediShield Life is designed to cover subsidised B2 and C ward bills well and higher wards poorly.

Which Integrated Shield Plan is best?

There is no best plan across the board. Compare the panel of specialists at the hospitals you would use, the rider’s annual co-payment cap, and the premium at your age and at seventy, which is where the private tier separates the insurers.

Can I switch insurers?

Yes, but the new insurer underwrites you afresh and can exclude conditions you have developed since your first plan. Switching is straightforward when young and healthy and rarely worthwhile after a diagnosis.

Does the plan cover treatment overseas?

Most plans cover emergency treatment overseas at Singapore-equivalent rates and planned overseas treatment only on the private tier, subject to limits. Read the overseas clause; it is where plans differ most.

Where this index comes from

Plan structures and the co-payment rules are from the Ministry of Health’s published guidance on Integrated Shield Plans and riders and from the insurers’ current policy documents. Premium and limit figures change yearly and are described here as bands; the insurer’s own schedule is the source of record.
