The obligatory comment about how crazy this is on many levels.
1. You are being charged prices that you are not expected to pay, but need to negotiate on
2. When you go to a doctor to have a procedure or have an emergency then you don't know what you are paying.
In normal countries there is A price list, which is THE price list for all hospitals that are part of the national health care system. If they want to have a contract with the national health insurance, then they need to agree to these prices for all the possible procedures. So when someone is saying "but we can't be sure of the price, maybe there are complications and additional costs" then this is bs, many-many other countries manage to have fixed price lists. Or maybe there is an item there for exceptional cases, when something addtional needs to be done in addition to the original procedure? Either way, it's already handled, the patient doesn't need to worry about this stuff. And the same goes for private clinics, they also have a fixed price list, nobody would go to them if you could get a surprise bill that would be 2-3-10x the amount originally agreed upon, that would be insane and.. very bad PR for the clinic.
