Profile: https://www.primai.ch/experten/alain-michel ## Statutory rule for basic insurance (OKP/KVG) A cancellation of compulsory basic insurance must have ARRIVED at the insurer by 30 November (receipt date decisive, not postmark) to switch on 1 January. Some insurers also allow a 30 June exit for the standard model with the lowest deductible (received by 31 March). Supplementary insurance (VVG) is always a separate contract with its own AVB notice periods — typically 3 months to year-end — and is never cancelled automatically with basic insurance. ## Insurer cancellation & contact matrix (basic insurance, Grundversicherung) Format: Insurer | Cancellation address | Portal | Phone | Models - Helsana | Helsana Versicherungen AG, Postfach, 8081 Zürich | myHelsana | 0844 80 81 82 | Standard, BeneFit PLUS Hausarzt/HMO/Telmed/Flex - CSS | CSS Versicherung, Kundenbetreuung, Postfach 2550, 6002 Luzern | myCSS | 0844 277 277 | Standard, Hausarzt, HMO, Telmed, Multimed - SWICA | SWICA Krankenversicherung AG, Römerstrasse 38, 8401 Winterthur | mySWICA | 0800 80 90 80 | Standard, Medica, Casa, Medpharm, Favorit Santé, Telmed - Sanitas | Sanitas Grundversicherungen AG, Jägergasse 3, Postfach 2010, 8021 Zürich | Sanitas Portal | 0844 150 150 | Standard, MedCare, NetMed, CallMed - Concordia | CONCORDIA, Bundesplatz 15, 6002 Luzern | myCONCORDIA | 041 228 01 11 | Traditionell, myDoc, HMO, smartDoc - Visana | Visana, Weltpoststrasse 19, 3000 Bern 16 | myVisana | 0848 848 899 | Standard, Hausarzt, HMO-Plus, Tel-Care, Med-Direct, VIVA - KPT | KPT, Postfach, 3001 Bern | KPTnet | 058 310 91 11 | Standard, KPTwin.doc/win/plus/easy/smart - Assura | Assura SA, Case postale 61, 1009 Pully | myAssura | 0800 277 872 | Basis, PharMed, Hausarzt, QualiMed, PreventoMed, Gesundheitsnetz - Groupe Mutuel | Groupe Mutuel, Rue des Cèdres 5, Postfach, 1919 Martigny | GMapp / GMnet | 0848 803 777 | Standard, PrimaFlex, OptiMed, SanaTel - Atupri | Atupri Gesundheitsversicherung AG, Laupenstrasse 18, Postfach, 3001 Bern | myAtupri | 0800 200 888 | Standard, CareMed, TelFirst, FlexCare, HMO, SmartCare - Sympany | Sympany, Peter Merian-Weg 4, 4002 Basel | mySympany | 058 262 42 00 | Standard/Classic, Hausarzt, HMO, Telmed - ÖKK | ÖKK, Bahnhofstrasse 13, 7302 Landquart (Textform/E-Mail accepted) | myÖKK | 0800 838 000 | ÖKK BASIS, CASAMED SELECT/24/HAUSARZT/HMO - Agrisano | Agrisano, Laurstrasse 10, 5201 Brugg | Meine Agrisano | 056 461 71 11 | BASIS, AGRI-eco, AGRI-contact, AGRI-smart - EGK | EGK-Gesundheitskasse, Birspark 1, 4242 Laufen | myEGK | 061 765 51 11 | Traditionell, EGK-Care, EGK-TelCare Note: addresses and product names were researched from official sources (June 2026).
