You can apply for prior authorisation if you live in another EU or EEA country or in Switzerland. You must always seek prior authorisation from the authorities in your country of residence, even when the costs of your treatment are not covered by your country of residence. Prior authorisation is granted using form S2. Other types of prior authorisations are not accepted in Finland.

The prior authorisation is a promissory note, based on which the party granting the permission reimburses the state of Finland for the costs related to the treatment. Kela will reimburse Finland’s public healthcare for the costs and invoice them from the party that granted the prior authorisation.

In addition to the customer information and the treatment provider, the prior authorisation can be used to precisely register the time of treatment and the treatment or procedure that will be reimbursed in accordance with the prior authorisation. If you have prior authorisation from your country of residence for treatment provided in Finland, you will pay the same customer fees for the treatment as the residents of Finland. Deliver the prior authorisation to the treatment provider.

Authorisation is granted using form S2. The prior authorisation can only be used in Finland’s public healthcare. Other prior authorisations than form S2 are not accepted in Finland’s public healthcare.

If you have received treatment pursuant to the prior authorisation (form S2) in Finland’s private healthcare, you can apply for reimbursement for the treatment costs from Kela. Kela will reimburse costs on the basis of the Health Insurance Act and on similar grounds as for people covered by health insurance in Finland.

Prior authorisation must be granted if the treatment cannot be arranged in the country of residence

According to EU legislation, a patient shall be granted prior authorisation for treatment provided in another member state if

  • the treatment required by the patient is included in the selection of healthcare services in their country of residence


  • the treatment cannot be arranged in the patient’s country of residence within a time that can be medically justified, while taking into account the patient’s current state of health and the probable progress of the illness.

Therefore, prior authorisation does not have to be granted if the treatment is not included in the selection of services in the patient’s country of residence, or if the treatment can be arranged within a medically justified time in the country of residence.

Prior authorisation can also be granted at the authority’s discretion for reasons of language or culture even if the prerequisites are not otherwise met.
