You can change your ward type through HealthHub if you are scheduled for an upcoming admission. However, request for change of ward type can only be made up till one day prior to the date of admission, or if the admission is for a Day Surgery, cosmetic procedure or selected medical services.
Do note that you will not be able to change to another ward type within the day if you have paid an initial deposit. You may do so after 8am the following day after the payment has been processed.
