The information you have been given is correct. If you are resident here you must have a Swiss health insurance and although there are
exceptions to this, they are very limited.
While this may seem unreasonable to you, you need to understand how the Swiss system works. It is an extremely good system but, in order to work, everybody must be part of it.
There are certain
requirements imposed on the insurers which, quite simply, a company like BUPA could not, and probably not, want to meet. For example, you are accepted for the basic health cover, irrespective of pre-existing conditions, at normal terms and your premium cannot be increased, or cover reduced, no matter how bad your health may become. The companies providing this cover are supervised by the Federal Authorities and operate on a non-profit making basis and they also contribute to general health care programs and to a fund to to ensure that, in the event of a company getting into financial difficulties, the policyholders are protected. They also have a central billing system know as TarMed.
The basic cover is very
extensive and without limits on the amount you can claim. For supplementary insurance, the insurers can impose terms for pre-existing conditions but, once you have it they cannot refuse renewal or impose special terms even if you become critically ill.
You will probably have to take out a Swiss insurance but the good new is that you will be well covered in a country with excellent facilities and no worries that any future bad health will leave you uninsured.
