Hi Dulishun and welcome to the forum,
Doesn't sound right to me. I too was a cash patient and shocked at my discounted prices
Germany for me was about 1/2 price for a 3 day hospital stay. I ended up staying 9 days and hate to even think about what an American hospital would have charged me.
Who's your surgeon? Said it many times in the past, the primary concern is your choice of doctor. You have only one shot at success so choose carefully.
What's your circumstances?
Good luck, Dale
