Questione giuridica chiave
Whether the insurer must cover the dental treatment under mandatory health insurance for a severe, non-avoidable disease of the masticatory system.
Decisione estratta
Coverage is not owed because the diagnosis of juvenile progressive periodontitis under Art. 17 lit. b Ziff. 2 KLV was not shown with sufficient probability.
Motivazione estratta
The file-based expert report was usable; available radiographs were only from after age 25, while the relevant youth records, parostatus and regular plaque indices were missing. On that basis the disease could not be diagnosed as juvenile progressive periodontitis, and the insured person bore the risk of proof failure.
