 Singapore citizens and Permanent Residents warded in public hospitals receive government subsidies for their medical fees, which scale according to their chosen class of ward as well as their income.Since 1 January 2009, patients warded in B2 and C class wards in public hospitals undergo means testing to determine the level of subsidy they are entitled to, based on the average monthly income received over the last available 12-month period including bonuses for salaried employees.However, patients receiving services such as Day Surgery, A&E services, Specialist Outpatient and polyclinic visits receive standardised subsidies regardless of income without requiring means testing.
