It took me 4mo to get my old ankle injury that I've had since the teens, to get operated. I was in the lowest priority category and this happened just after Covid-19 hit. I got a quote from a private healthcare provider for the operation for 6000e. In the public one it ended up costing 120e.
Also, just as a sidenote, if you have no income other than governmental income support, Kela will pay these fees. So it is free for those who do not have the income to pay for it.
