Basic insurance in Lengnau: choosing insurer, deductible and model
You steer your premium in Lengnau with three levers. The insurer first — it costs nothing in benefits and brings the most. Then the deductible between 300 and 2’500 CHF: high deductible for healthy people with a financial cushion, low deductible for ongoing treatment or planned procedures. For comparison: with a 2’500 CHF deductible, the adult premium in Lengnau starts as low as 344 francs a month. Finally the insurance model: family-doctor, HMO or telemedicine are noticeably cheaper than 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 Aargau — many households leave this reduction unused.
Checklist for Lengnau
