At the times of the ending of the 19th and the beginning of the 20th century, the health insurance funds established by some of the larger Lithuanian industrial enterprises during that period were called “Krankenkasse” following the example of Germany. Historical data shows that health insurance funds helped business owners to aid sick workers since they took contributions from them, equal to up to 2,5 percent of their wage. However, the sickness funds of industrial enterprises were managed by the administration of the enterprises, so the help was scarce in case of illness.
In 1912 it was planned to introduce compulsory health insurance for industrial workers, but the plans were thwarted by the First World War. On 23 March 1926 The Seimas (Lithuanian Parliament) has passed the Law on the Chief Social Insurance Board, which regulates the establishment of the Board for the management of social insurance matters, and on 18 May, the President of the Republic of Lithuania Aleksandras Stulginskis announced this in the Government Gazette. The date of adoption or promulgation of this law can reasonably be considered the beginning of social insurance in Lithuania.
Health insurance funds in our country were established at the end of 1928. Lithuania, compared to its neighbors, was late: in Poland and Estonia, health insurance laws were passed in 1920, and in Latvia in 1922.
The first health insurance fund in Lithuania was established on 28 October 1928 In Kaunas. Soon six more health insurance funds appeared: Kaunas, Šiauliai, Marijampolė, Panevėžys, Ukmergė and Vilkaviškis counties. In 1931 these funds became county funds. Although in 1926, the Law on Health Insurance Funds, provided for the establishment of 21 health insurance funds, i.e. in order to have them in each county, only seven were established, uniting various counties.
In the year 1932 new county health insurance funds began to operate. There were nine of them, in addition, the Kaunas city fund was also working in this area. Soon six more funds of various companies and institutions were established: the Ministry of Transport and Communications, Eiguliai, „Elektra“ joint-stock company, the Bank of Lithuania, St. Zita Society, Vytautas Magnus University.
According to the law, all employed persons, regardless of gender or age, should receive compulsory health insurance by the health insurance funds (except for people employed for temporary works no longer than one month), people employed in the public service, people receiving more than 400 Lithuanian Litas per month and agricultural workers, were also to be covered by compulsory insurance. Later, the exception was extended to municipal employees. In addition to compulsory insurance, optional insurance for agricultural workers was introduced during that period, but it was not popular.
