If you have the ‘standard’ — and typically the most expensive — type of the obligatory health insurance (KVG / LaMal), then you are free to switch your GPs at will, and you don’t have to inform the insurance carrier of the switch. Under this model, you have a family doctor who will manage your care — that is, treat you or send you to specialists if needed (with the exception of gynecologists and eye doctors, who don’t require a referral). So the only option that gives you the right to switch doctors with no hassle is the standard one, with the family doctor model also possibly allowing you to do so, under certain circumstances.
