The Universal Coverage Scheme (UCS), also known as the Gold Card or 30-baht scheme, is the largest of the three Thai healthcare programmes that provide universal health care. It covers the majority of the population, and is directly funded by the national budget and allocated on a mixed per-capita basis by the National Health Security Office (NHSO). The programme was launched in 2002 during the government of Prime Minister Thaksin Shinawatra, based on foundational developmental work by public-health civil servants, especially Doctor Sanguan Nitayarumphong, beginning in the 1980s.
