Omnilex-Zusammenfassung

In a dispute concerning reimbursement of ambulatory treatment costs under social insurance tariff coverage, the tribunal held that the conclusion of a new tariff convention does not have retroactive effect for insured persons unless retroactivity is expressly stipulated. The decision emphasizes that coverage and reimbursement conditions under a tariff agreement are governed prospectively by the new convention, and that retroactive application cannot be inferred from the mere conclusion of the agreement.

Omnilex-Regeste

Art. 22bis al. 2 LAMA; new tariff convention and retroactivity: a later tariff agreement cannot be applied retroactively to insured persons unless the agreement expressly provides for such effect. In the absence of an explicit retroactive clause, the convention governs only for the future. The principle follows from the need for clarity and legal certainty in tariff-based reimbursement schemes and from the protection of good faith in the determination of insurance coverage (consid. not specified).
