Policy Note: Thailand Health Systems in Transition<br>By 2002, Universal Health Coverage was achieved through three public insurance schemes: the Civil Servant Medical Benefit Scheme (CSMBS) for civil servants and their dependents, Social Health Insurance (SHI) for formal sector employees, and the Universal Coverage Scheme (UCS) for the remainder of the population.<br> The establishment of these three schemes has changed the way health care is financed. A supply-led system, under which all Ministry of Public Health (MOPH) health facilities received an annual budget allocation from the MOPH, has now been completely replaced by a system in which the three public purchasers - separated through a purchaser-provider split - manage a demand-led system of financing.
