This depends a lot on what you have to see the doctor about. If its just for feeling sick and not much is wrong then the visit should be 50-100CHF depending where you go.
Fees will vary between Zurich stadt and further out as doctors outside Zurich are less expensive especially if the tax charge rate is lower
Looking at a recent bill from the Universitatspital in Basel, a basic consultation (excluding any test fees) costs approximately CHF16- for each five minutes.
If you have an excess you can do whatever you want as your paying with your own money. Same with perscriptions France is often much cheaper than Germany-
Just be careful - if it's your first visit then you may well have to pay. I had to pay by card the first time I went to the doctor. I've also just changed doctor and I saw her for the first time today. She informed me a bill would be coming to my house.
