Key legal question
Whether CSS had to cover supplementary hospital costs for treatment in a clinic without a tariff agreement.
Extracted holding
No. The AVB limited coverage to hospitals with a tariff agreement; the clinic had none, so no supplementary benefit was owed.
Extracted reasoning
Art. 13.1 AVB was restricted by Art. 13.2 AVB. The insured was not party to the tariff contract, and the clauses were clear and not unusual.
