Thailand — The Universal Coverage Scheme

Thailand's Universal Coverage Scheme, widely known as the "30 Baht Scheme," was introduced in 2001 following the election of the Thai Rak Thai party, which had campaigned on a promise of a flat 30-baht fee for medical treatment. The government implemented the policy within three months of taking office. The National Health Security Act, passed by parliament in November 2002, formalized the program and created the institutions that continue to manage it.

The scheme covers everyone in Thailand not already covered by the Civil Servant Medical Benefit Scheme or the Social Security Scheme — in practice, the bulk of the population previously uninsured or covered only by narrower, partial welfare schemes. It was financed from general government revenue rather than member premiums, and the flat per-visit fee was later eliminated entirely for enrollees. Certain groups — children under twelve, adults over sixty, the very poor, and volunteer health workers — were designated for free access from the start.

Independent assessments, including a widely cited 2007 analysis in Health Affairs, found the reform succeeded in extending coverage rapidly to a large previously uninsured population, and documented it as a notable achievement among lower-middle-income countries pursuing universal coverage during a period of domestic economic downturn.

At the same time, specific studies of the scheme's effect on the urban poor — including research conducted in a Khon Kaen slum community — found that the functioning of exemption categories and their actual effect on health service use among the poorest residents was mixed and, in the researchers' own words, controversial. The reform's political footing was also tested directly: following the 2006 military coup, Thai policymakers undertook a formal reappraisal of the coverage reforms.
