As-Charged Plan (Insurance) Singapore: How Full-Reimbursement Shield Riders Work

Last updated: August 2026

An as-charged plan is an Integrated Shield Plan rider structure that reimburses a policyholder’s actual eligible hospital bill in full, or close to it, rather than paying out fixed cash benefits per treatment item regardless of the bill size.

Key Takeaways

As-charged plans reimburse the actual, eligible medical bill amount, subject to plan limits and any co-payment, instead of paying fixed cash sums per procedure or day of stay.
The alternative structure, cash benefit or scheduled benefit plans, pays a predetermined fixed amount per claim type regardless of the actual bill, which can leave a larger out-of-pocket gap for expensive treatments.
Most Integrated Shield Plan riders in Singapore introduced co-payment features from 2021 onward, meaning even as-charged riders typically require the policyholder to bear a percentage, often 5%, of the bill above the deductible.
As-charged riders generally come with higher premiums than cash benefit riders, reflecting the insurer’s greater exposure to large, unpredictable hospital bills.
MAS has actively pushed the insurance industry toward co-payment features specifically to address concerns that first-dollar, fully-as-charged coverage without any co-payment was driving up overall healthcare and premium costs in Singapore.

What Is As-Charged Plan (Insurance) Singapore?

Integrated Shield Plan riders in Singapore historically came in two broad structures: as-charged, which reimburses the actual eligible bill amount, and cash or scheduled benefit, which pays a fixed dollar amount per treatment category regardless of what was actually billed. As-charged plans became popular because they offered close to first-dollar, full-bill coverage with minimal out-of-pocket exposure for the policyholder, particularly for private hospital treatment where bills can vary enormously. Concerns that this structure removed any cost discipline — since neither patients nor providers had much incentive to control spending when insurers paid whatever was charged — led MAS and the Life Insurance Association Singapore to require co-payment features on new as-charged riders from April 2021 onward.

How Does It Work in Singapore?

Under an as-charged rider, a policyholder submits their actual hospital bill, and the insurer reimburses the eligible portion up to the rider’s coverage limits, minus any deductible and co-payment. Since the 2021 reform, most as-charged riders require the policyholder to pay a percentage co-payment, commonly around 5%, of the bill above the annual deductible, up to an annual cap on total co-payment exposure. This differs fundamentally from a cash or scheduled benefit rider, which instead pays a fixed sum, for example a set dollar amount per day of hospitalisation or per surgical procedure category, regardless of what the hospital actually charged — meaning a policyholder could receive far less than the actual bill if treatment costs exceed the scheduled amount, or in rarer cases, effectively more if actual costs come in lower.

Example

A policyholder incurs a S$40,000 private hospital bill for a major surgery. Under an as-charged rider with a 5% co-payment above a S$3,500 deductible, the policyholder pays the deductible plus 5% of the remaining S$36,500 — about S$1,825 — bringing their total out-of-pocket cost to roughly S$5,325, with the insurer covering the remaining approximately S$34,675. Under a cash benefit rider that pays, say, a fixed S$15,000 for that surgical category regardless of the actual bill, the policyholder would instead be responsible for the S$25,000 shortfall themselves.

Advantages

Provides much closer to full reimbursement of actual medical costs, which matters most for expensive, unpredictable private hospital treatment where bills can vary widely from case to case.
Reduces the risk of a large, unexpected out-of-pocket shortfall that can arise under a fixed cash benefit structure if actual treatment costs exceed the scheduled payout.
Co-payment features introduced since 2021 still leave meaningful cost-sharing responsibility with the policyholder, which can encourage more judicious use of higher-cost private healthcare options.
Well suited to policyholders who prioritise private hospital access and want their actual bill closely covered rather than accepting a fixed payout that may not match real costs.

Risks and Limitations

As-charged riders generally carry meaningfully higher premiums than cash benefit riders, reflecting the insurer’s greater exposure to variable, potentially large hospital bills.
Co-payment obligations, even at a modest percentage like 5%, can still translate into a significant absolute out-of-pocket sum for very large bills, so the coverage is not entirely first-dollar.
As-charged structures have historically been linked to rising overall healthcare costs in Singapore, since neither patients nor providers face strong incentives to contain spending when bills are reimbursed close to in full.
Premium increases on as-charged riders have tended to be steeper over time than for cash benefit riders, partly reflecting the same cost-inflation dynamics the co-payment reform aimed to address.

As-Charged Plan vs Cash (Scheduled) Benefit Plan

Feature	As-Charged Plan	Cash / Scheduled Benefit Plan
Payout basis	Actual eligible bill amount	Fixed sum per treatment category
Out-of-pocket risk on large bills	Lower, subject to co-payment and limits	Higher if actual cost exceeds scheduled amount
Premium level	Generally higher	Generally lower
Cost-control incentive	Weaker (co-payment partially offsets this)	Stronger, since payout is capped regardless of bill
Best suited for	Those prioritising private hospital access	Those seeking a lower-premium, predictable payout structure
Co-payment required (post-2021)	Typically yes, around 5% above deductible	Not applicable — payout is fixed regardless of co-payment

The Bottom Line

An as-charged plan gives Singapore policyholders coverage much closer to their actual hospital bill, at the cost of a higher premium and, since 2021, a co-payment obligation designed to keep both patients and the healthcare system cost-conscious.

Frequently Asked Questions

What is an as-charged plan in Singapore health insurance?

It is an Integrated Shield Plan rider that reimburses a policyholder’s actual eligible hospital bill, subject to plan limits and co-payment, rather than paying a fixed cash sum per treatment regardless of the real bill amount.

How is an as-charged plan different from a cash benefit plan?

An as-charged plan pays based on the actual bill incurred, while a cash or scheduled benefit plan pays a predetermined fixed amount per treatment category regardless of what the hospital actually charged.

Do as-charged plans in Singapore still have co-payment?

Yes, since April 2021 MAS and LIA Singapore requirements mean most as-charged riders include a co-payment feature, typically around 5% of the bill above the annual deductible, up to a yearly cap.

Are as-charged plans more expensive than cash benefit plans?

Generally yes, because the insurer bears more exposure to large, variable hospital bills under an as-charged structure compared to a fixed-payout cash benefit structure.

Why did Singapore introduce co-payment on as-charged plans?

MAS and the insurance industry introduced co-payment to address concerns that fully as-charged coverage without cost-sharing was contributing to rising private healthcare and premium costs over time.

Which is better, an as-charged plan or a cash benefit plan?

It depends on priorities — an as-charged plan suits those who want closer-to-full reimbursement for potentially large private hospital bills, while a cash benefit plan suits those prioritising lower premiums and are comfortable with a fixed, predictable payout.
