Basic insurance in Gossau: choosing insurer, deductible and model
Three decisions drive your premium in Gossau. First, the insurer: with legally identical benefits, it is the biggest lever for saving. Second, the deductible (300 to 2’500 CHF a year): if you rarely see a doctor and hold a reserve, the high deductible is usually the better deal; with regular treatment, choose the low one. For comparison: with a 2’500 CHF deductible, the adult premium in Gossau starts as low as 351 francs a month. Third, the model: family-doctor, HMO or telemedicine models cut the premium significantly compared with free choice of doctor.
Important for switching: your cancellation of basic insurance must REACH your current insurer by 30 November at the latest (the date of receipt counts, so send it by registered post) for the switch to take effect on 1 January. Also check whether you qualify for premium subsidies in the canton of St. Gallen — many households leave this reduction unused.
Checklist for Gossau
