Insurance Claims in Singapore: How to Claim Medical Expenses

A hospital bill may be paid through more than one source: MediShield Life, an Integrated Shield Plan (IP), employer medical benefits, MediSave and, in some cases, another insurance policy. The hard part is not filling in one form. It is knowing what to declare, which benefit applies first, and what you may still need to pay.

For planned treatment, check your cover before admission, not after discharge. This guide explains how medical insurance claims usually work in Singapore and what to do when a claim is reduced, delayed, or rejected.

Which insurance can you claim from?

The right claim route depends on the treatment and policy you hold.

Hospital or day surgery: MediShield Life and IPs

MediShield Life covers Singapore citizens and Permanent Residents for large hospital bills and selected outpatient treatments. An IP adds private insurance coverage to your MediShield Life coverage, with benefits that depend on your plan.

For a hospital stay or day surgery, the medical institution typically handles MediShield Life claims as part of the billing process. If you have an IP, provide your insurance details and complete the required claim and MediSave authorisation forms. Any insurance payout goes to the medical institution to offset your bill.

Company group medical insurance

Your employer's medical benefits usually come in two parts. Group Hospital and Surgical (GHS) insurance covers hospital stays and surgery, and can help with costs your IP doesn't fully pay. Outpatient GP and specialist visits are usually covered under a separate outpatient benefit.

The scope varies widely. Some plans only cover visits to panel clinics or doctors. Others allow reimbursement for non-panel care, often with separate limits or documentation requirements.

If you have both company insurance and a personal IP, declare both plans to the hospital financial counsellor and your insurers. Do not assume that one plan will automatically coordinate with the other.

Personal accident medical claims

Personal accident insurance may cover eligible medical expenses caused by an accident, subject to the policy’s limits, exclusions and reporting requirements. It is not a replacement for hospital insurance and usually does not cover treatment for illness.

The insurer may ask for an accident report, medical memo, itemised bills and proof of payment. Check the policy’s claim deadline, as deadlines differ between insurers.

Critical illness insurance

Critical illness insurance usually pays a lump sum when you meet the policy’s definition of a covered condition. It does not reimburse the hospital bill line by line.

You may use the payout for treatment, household expenses, recovery needs or other financial commitments. The claim outcome depends on the policy definition, waiting periods, exclusions and medical evidence, not on whether the hospital bill has already been paid.

Travel, motor and other insurance

Travel insurance may cover emergency medical treatment overseas, while motor insurance is involved after a road traffic accident. These policies have their own reporting rules, exclusions, overseas treatment requirements and claim processes.

This article focuses mainly on medical claims in Singapore. Contact the relevant insurer promptly if your treatment arises from travel, an accident or another insured event.

How a medical insurance claim works for a hospital bill

For many hospital and day-surgery bills, the medical institution can submit MediSave, MediShield Life and IP claims for you. You may still need to settle any deposit, deductible, co-payment, exclusions or amount above your available benefits.

Cashless or reimbursement: Which applies?

“Cashless” does not always mean you pay nothing. It can mean the hospital bills the insurer directly for the eligible portion of treatment.

You may still need to pay:

• Your deductible
• Co-insurance or co-payment
• Non-covered treatment or medication
• Charges above the policy’s claim limits
• Services excluded under your plan
• A hospital deposit, where required

If the hospital or clinic cannot submit a claim directly, you may need to pay first and seek reimbursement from the insurer. Ask before treatment which payment route applies.

The Medical Claims Authorisation Form

To use your MediSave, MediShield Life or IP for treatment, you'll need to sign a Medical Claims Authorisation Form (MCAF). It gives the medical staff your consent to advise you on your payment options and submit claims on your behalf, so you don't have to file them yourself.

There are two versions of the form:

• MCAF(S): A separate authorisation for each institution or visit. You'll need this for private hospitals and clinics, or if you'd prefer to give authorisation visit by visit.
• MCAF(M): A one-time authorisation covering your current and future treatment at all participating institutions. You can submit it on paper or online through HealthHub. It's optional, but it saves you signing a new form every time.

If you're using a family member's MediSave to pay, you must use MCAF(S), even at an institution that accepts MCAF(M).

The admissions or billing staff will usually give you the right form when you're admitted or register for day surgery. For eligible claims, the hospital applies the expected MediSave, MediShield Life and IP amounts to your bill. You're still responsible for any deductible, co-insurance or co-payment, excluded charges and amounts above your benefit limits, though MediSave can often cover part of this.

Who pays first if you have more than one policy?

MOH sets the order for people covered by more than one scheme:

1. Your employer's plan, other private insurance or another responsible third party
2. MediShield Life or your IP
3. MediSave, within its withdrawal limits
4. Cash for whatever's left

Your IP pays the portion the earlier payers didn't cover, subject to its claim limits, deductible and co-insurance.

The order matters because payments get reversed if it's wrong. If your IP pays first and your company insurance pays later, the amount your IP covered has to be paid back to your IP, so you end up with more paperwork.

If you have company insurance, an IP and a personal accident plan, WhatsApp our Care Team, who can help you work out which policy pays first and what to tell the hospital at admission.

Reimbursement cover and fixed benefits

Reimbursement policies pay back what you actually spent, and together they can't pay more than your eligible bill. Fixed-benefit policies pay a set amount when their conditions are met, whatever the bill says.

MediSave sits outside both. It isn't insurance, it's your own savings, and it comes after your insurers have paid, within the withdrawal limits for your treatment.

Before admission: The steps that affect your claim

The most useful insurance checks happen before planned surgery or admission, not after discharge.

Check the doctor and hospital

For company medical benefits, check whether the clinic, specialist or hospital is on your employer’s panel. Ask whether you need a GP referral and whether the plan uses direct billing or reimbursement.

For IP treatment, check whether the treating specialist is on your insurer’s panel. The hospital, anaesthetist, assistant surgeon, implants and other related services may also affect the final bill.

A panel provider does not guarantee full cover, but it will make pre-authorisation and claims easier.

Request pre-authorisation for planned treatment

Pre-authorisation is an insurer’s assessment of proposed treatment and associated charges before treatment takes place. It can clarify the expected claim arrangement for a planned procedure, surgery or hospital admission.

It is not a blank cheque. The final claim remains subject to the treatment provided, policy terms, exclusions, supporting documents and applicable benefit limits.

Before admission, ask:

• Is pre-authorisation available for this treatment?
• Is the specialist on my insurer’s panel?
• What co-payment and deductible terms may apply?
• Does the insurer need a medical memo, referral or cost estimate?
• Does the assessment include hospital, anaesthetist, implant and assistant-surgeon fees?

Questions for the hospital financial counsellor

Before a planned admission, ask:

• What's the estimated total bill, including surgeon, anaesthetist, implants and hospital charges?
• Which of these are likely to be claimable, and which aren't?
• What deposit will I need to pay, and does pre-authorisation change that?
• How much can MediSave cover?
• What will I likely pay in cash?

Declare every policy you hold, including company cover. The hospital can only bill the payers it knows about, and a policy that surfaces later usually means refunds, adjustments and delay.

At admission and discharge

At admission

The hospital may ask you to sign consent forms, an admission form, the MCAF and insurer-specific paperwork. Provide accurate information about your insurer, employer benefits and MediSave use.

Read any financial consent carefully. If you are using a family member’s MediSave, the account holder may need to provide their identification and authorisation.

At discharge

Your final bill may differ from the initial estimate because treatment, medication, tests or length of stay can change.

Check the bill for your deductible, co-insurance or co-payment, and any excluded or non-covered items. If you have an IP rider, the terms depend on your policy version and the date the rider was purchased.

New IP riders sold from 1 April 2026 can't cover the minimum IP deductible. They must include a co-payment of at least 5%, with an annual cap of at least S$6,000 on top of the deductible, for claims that meet the insurer's conditions, such as using a panel doctor or getting pre-authorisation. You can use MediSave for both the deductible and co-payment, within withdrawal limits. Older riders may work differently, so check your policy.

Documents to keep

Keep digital and paper copies of:

• Itemised final hospital bills and receipts
• Discharge summary
• Medical memos and reports
• Referral letters
• Pre-authorisation or LOG correspondence
• Insurer claim statements and settlement letters
• Accident reports, if relevant
• Proof of payment

These documents can help if a company insurer, personal accident insurer or other policy requires a separate claim.

How to file an insurance claim yourself

You may need to submit a claim yourself when the clinic does not provide direct billing, when you use non-panel care, or when you claim under a personal accident, travel, critical illness or employer reimbursement policy.

When you may need to submit the claim yourself

Hospitals handle most inpatient claims for MediShield Life, IPs and MediSave. You may need to submit a claim yourself if you have paid the bill in full and the provider does not submit it on your behalf, if your outpatient or non-panel visit requires reimbursement, or if you are claiming a fixed benefit such as a critical illness or personal accident lump sum.

Documents insurers usually ask for

• A completed claim form, from the insurer's app, portal or a paper form
• The itemised bill and proof of payment
• The discharge summary or medical report
• A referral letter or medical memo, where your plan requires one
• An accident report, for accident-related claims
• The first insurer's settlement letter, if you're claiming a balance

Exact requirements vary, so check your insurer's claims page before you submit.

Deadlines, channels and tracking

Every insurer sets its own deadline, and company plans often have shorter ones than personal policies. Submit as soon as you have the documents rather than waiting until the end of the benefits year. Most insurers now accept digital submissions and let you track progress in their app, and you'll receive a claim outcome letter when the assessment is done.

Why medical insurance claims are reduced or rejected

Rejected vs partially paid: What is the difference?

A rejected claim is one the insurer won't pay at all, usually because the treatment, condition or provider falls outside your policy. A partially paid claim is one the insurer accepted but paid less than the bill, because of claim limits, deductibles, co-insurance, pro-ration or non-panel terms.

The two need different responses, so read the outcome letter carefully to see which one you're dealing with.

Common reasons a claim may be reduced or rejected

• The treatment isn't covered, or falls under an exclusion
• A pre-existing condition or waiting period applies
• Pre-authorisation was required and wasn't obtained
• A non-panel provider was used, and your plan pays less for that
• The bill exceeds your claim limit for that treatment
• Your higher ward class triggered pro-ration
• Documents were missing or incomplete

What to do if you disagree

Start with the insurer. Ask for a written explanation of which items were reduced/rejected and why, then supply anything that supports your case, such as a letter from your specialist explaining why the treatment was necessary.

If your claim outcome letter is hard to follow, WhatsApp our Care Team. We can help you identify which items were reduced and prepare the practical questions to ask your insurer.

For a formal dispute, first use the insurer's internal complaint process. If the matter remains unresolved and falls within its scope, you may approach FIDReC. FIDReC is an independent dispute-resolution body for eligible disputes between consumers and financial institutions. It can mediate eligible disputes without a claim limit. If mediation does not resolve the matter, adjudication is generally available for claims of up to S$150,000 filed on or after 1 July 2024. A nominal adjudication fee applies.

Get clarity before you are admitted

Most claim problems are decided before treatment, not after it. Which specialist you see, whether pre-authorisation is in place, and which policy the hospital bills first all shape what you pay. Health in Asia is an independent medical concierge. Before starting HiA, our team spent years inside a private healthcare group in Singapore, running operations, managing specialist networks and working with the insurance and billing processes most patients never see.

Our Care Team can help you:

• Check whether your specialist and hospital are on your insurer's panel, and what that means for your claim
• Understand what your plans are likely to cover and what you may pay yourself, including what MediSave can take care of
• Work out which policy pays first and what to declare at admission
• Find out whether your treatment needs pre-authorisation, what your doctor has to submit, and how early to apply
• Compare what a public and a private admission may cost you, if your plan only covers public hospital wards
• Go through a reduced or rejected claim with you, identify which charges were cut and why, and decide what to raise with your insurer

WhatsApp our Care Team with your condition and insurance details, and we'll help you plan the next step. Your insurer remains responsible for confirming your coverage, pre-authorisation and claim outcome.
