CSS — FAQ
What is the CSS myFlex system?
Supplementary cover in three tiers (Economy, Balance, Premium) per module — outpatient, hospital, alternative medicine. You combine only what you need and can step down later. Often more flexible than rigid packages.
Is CSS cheap?
It varies by region — usually solid mid-table. With a Telmed/HMO model and the right deductible CSS is often competitive; whether it leads in your premium region shows in seconds in the premium calculator.
How do I switch to or away from CSS?
Basic insurance: your cancellation must reach the insurer by 30 November (registered mail is safest), and you switch from 1 January. With the CHF 300 deductible and the standard model you can also switch for 1 July if your notice arrives by 31 March. Supplementary cover follows the policy terms; by law you can cancel at the end of the third policy year and every year after that with three months’ notice (Art. 35a VVG). New supplementary cover involves health questions, so never cancel before the new cover is confirmed. We can handle the switch for you.
Do I pay more premium through insurance-guide.ch?
No. Basic-insurance premiums are officially approved and identical whether you sign up directly or through us. We are paid by the insurers via commission; how that works is explained transparently on our advisory page.
