Costa Rican Social Security Fund (Caja Costarricense de Seguro Social)

The Costa Rican Social Security Fund (Spanish: Caja Costarricense de Seguro Social) is in charge of most of the nation's public health sector. Its role in public health (as the administrator of health institutions) is key in Costa Rica, playing an important part in the state's national health policy making.

Its services are available to all citizens and permanent legal residents. This governmental entity's functions encompass both the administrative and functional aspects. Originally, services were carried out at private hospitals but funded by the Costa Rican Social Security Fund. Not until the mid-1960s did the Caja begin constructing its own hospitals staffed by public employees.[2] It has the obligation (as a public institution) to formulate and execute health programs that are both preventive (such as: vaccination, informational, fumigation, etc.) and healing (such as: surgery, radiation therapy, pharmacy, clinical, etc.) in nature.[3]

The Costa Rican Social Security Fund is also charged with the administration of the public pension system.
