I was at the dentist today because I managed to chip a tooth yesterday, and needed it fixed. Before the procedure, they asked if I wanted an estimate, I said sure, and got one in a minute.
The dental industry works the same as the medical, I have a half-useless insurance that covers too little, and out-of-pocket expenses are always higher than you expect. But if they can do estimates before a procedure, why the hell can't the medical industry do the same?
