The Community Health Assist Scheme (CHAS) gives Singapore Citizens subsidies at participating GP and dental clinics for common illnesses, 23 chronic conditions, selected dental care and recommended health screening. Every Singapore Citizen can apply. The colour of your card, Blue, Orange or Green, sets your subsidy tier, and Pioneer Generation and Merdeka Generation seniors receive special subsidies with their PG or MG card.
CHAS lowers the bill, but it does not necessarily cover all of it. You pay the clinic's fee minus your subsidy, which depends on your card, the reason for your visit and any yearly limit already used. At Fusion Medical, you can use CHAS Blue, Orange and Green, Pioneer Generation and Merdeka Generation cards, but not Public Assistance cards.
