The Elderly Health Care Voucher Scheme aims to encourage utilization of private primary healthcare services, including dental service, by the elderly. Since its pilot implementation in 2009, the voucher amount has been increased several times and its scope has been continuously expanded. Currently, eligible elderly persons can receive an annual voucher amount of HK$2,000, and the unspent voucher has no expiration date and can be accumulated up to a ceiling of HK$8,000.
