A foreigner has to take into account that in the smaller cities or areas is it harder to find or receive a medical care.
The foreigner is allowed to go to private and public hospitals. If the insurance does not cover treatment, you have to pay before leaving the hospital or within a month.
Foreign nationals with health problems seeking medical treatment in Argentina can apply for a 1-year multiple-entry medical visa at the Nacional de Migraciones.
If the treatment is made in a public hospital has to be signed by the director of the hospital in order to get the visa.
If the treatment is made in a private clinic, the statement has to be legalized by the Health Department.
