Apply for a Letter of Guarantee (LOG)

How does the Letter of Guarantee (LOG) work?

You may request for a LOG in the event that you are unable to settle the pre-admission deposit. An LOG will only be issued for day surgery and inpatient hospital treatments, and will not be applicable for outpatient treatments such as kidney dialysis, cancer treatment, and consultation.

The LOG can be used to waive the deposit for up to SGD80,000 in restructured hospitals, and up to SGD50,000 in private hospitals.


How to request for an LOG

You can apply for an LOG at the hospital when you're admitted. There is no need to request for an LOG with us in advance.

Simply inform the hospital staff when you arrive that you are covered under GREAT SupremeHealth. They will be able to assess if you are eligible based on the following criteria:

  • You are covered under GREAT SupremeHealth.
  • You are a Singapore citizen or permanent resident.
  • Policy is in-force at the date of hospital admission.
  • You are accepted for cover at standard risk.
  • The medical conditions and treatments are not excluded from the policy.

If eligible, you will need to sign the Medical Claims Authorisation Form (MCAF) before the LOG can take effect.

Alternatively, if you call Health Connect if you are seeing our panel specialist for your planned admission/surgery to request for pre-authorisation for your proposed medical and surgical expenses. Once the pre-authorisation is completed and approved, a Certificate of Pre-authorisation will be issued.

This Certificate of Pre-authorisation waives off the deposit requirement upon admission and also enable for Great Eastern to settle the medical and surgical expenses directly with the hospital after discharge.

Please refer to FAQ on Health Connect for more information.

The issuance of a LOG is not guaranteed. In some circumstances, your request for a LOG may be declined. This includes, but is not limited to, not fulfilling the pre-set rules for LOG eligibility. Great Eastern reserves the right, at its discretion, to decline the request for a LOG in circumstances not listed under the pre-set rules.

The issuance of an LOG does not guarantee a full or partial waiver of the pre-admission deposit. The LOG is still subjected to acceptance by the hospital. The hospital may still, at its discretion, require you to fully settle the hospitalisation or day surgery bill upon discharge, despite the submission of an LOG.

The issuance of a LOG does not indicate an approval on any claim or claim amount in respect to the cause of admission payable under your GREAT SupremeHealth. A claim would still need to be submitted and assessed by us.

The LOG amount may not be the actual sum that you are entitled to claim under the policy. The final amount of claim paid upon a claim settlement may deviate from the LOG amount.

You need to sign the Medical Claims Authorisation Form (MCAF) before the LOG can take effect. The hospital staff will pass you the form when you are admitted.

We regret to inform that we will not be able to issue another LOG.

No, LOG is only available to eligible to those covered under GREAT SupremeHealth.
