I have no idea how this stuff works, since luckily, I've never had to use my health insurance for anything other than annual doctor visits and minor prescriptions. So I see I have a deductible of $X, I pay Y% of the cost after deductible, and there is a $Z max out of pocket expense. Can I just budget for the hospital bills to cost $Z? Is it possible to get charged in excess of $Z? Thanks for any insight!
