On December 3, 2025, the Swiss Federal Office of Public Health published updates to the Healthcare Benefit Ordinance (KLV/OPre), which determines coverage of medical services in Switzerland. The changes will take effect on January 1, 2026, and relate to prophylactic vaccinations, cost containment measures, and other matters. The updates are also implemented in KLV Annexes, including the List of explicitly evaluated services (Annex 1), the outpatient-before-inpatient mandate (Annex 1a), the List of Medical Aids (Annex 2, MiGeL), and the List of Analyses (Annex 3, AL).
