The Hotel Terme Millepini is a hotel recognised by the German Sickness Insurance Funds in which it is possible to undergo a course of thermal cures.
The German Health Insurance System recognises thermal cures throughout the European Economic Area, thus also in Italy, under certain conditions: that the treatment is carried out in a location recognised by them and that there is a prescription from one's attending physician stating that it is necessary for medical reasons.
All insured persons who wish to undergo a course of thermal cures and have chosen Hotel Terme Millepini require a prescription from their treating doctor and authorisation from their competent German health insurance fund.
The competent health insurance fund bears part of the costs incurred by the insured person such as physiotherapy, medical treatment and accommodation costs.
If the treatment is carried out abroad, the same costs are refunded as if the treatment had taken place in Germany, taking into account, however, that a lump sum for administrative costs may be determined as reimbursement.
