Well, first of all, if you are living in Geneva you will certainly have health insurance and if your doctor recommends that you should have this examination he/she will prepare the documentation you need to make a claim on your health insurance.
Secondly, you can always discuss insurance coverage issues with your doctor so that he/she can give you an estimate of the cost of a procedure and any follow-up treatment or care.. He can also arrange to refer you to a service whose tariff dovetails with your insurance coverage.
Many people are reluctant to discuss finance with a medical practitioner but personally
my questions about the financial implications of treatment and convalescence have always been handled in a discreet and sympathetic manner and generally speaking the financial “estimates” have been in line with the expected outlay.
Best wishes in any event,
