If the patient is admitted to the hospital for an overnight stay, this is referred to as an inpatient treatment. Under the Directive (i.e. if the path via Regulation (EC) No 883/2004 is not followed with the EHIC or form S2), foreign patients are treated only in exchange for payment (cash, credit cards, etc.) in hospitals with beds that are financed by the respective regional health fund ("subsidized hospitals"). The treatment costs are calculated according to the Austrian "DRG system" (procedure-oriented financing).
In addition there are hospitals with beds that are financed from another fund, the Private Hospitals Financing Fund (PRIKRAF). The treatment costs in these hospitals are composed of a percent calculated according to the DRG system and a percent established by the respective hospital. As in the private practice area, the principle of freedom to establish fees applies to these as well as to all other hospitals with beds not financed by a regional health fund (private hospitals). The treatment costs in the outpatient area are established by the respective province.
In Austria, bills for treatment costs are issued by the hospitals or by the respective legal representative of the hospitals. The latter are also a source of information on the costs to be expected.
