If you have private health care coverage, what sort of out-of-pocket costs would you normally have to pay within your system?

As asked.

If you have to go to the doctor, have surgery or some other medical intervention, how much of the doctor’s/hospital’s etc. fees are covered by your health care provider? What level and type of out-of-pocket expenses would you expect to have to pay? How much does your healthcare cost you and what does it cover?
