Personally, I avoid the very high deductible plans, mostly because I have the option, but also because I don't want to deal with hospital billing. I've got an HMO (kaiser) and they charge me almost nothing at point of service, and I get to consume all the medical care my doctor thinks I need.
Unfortunately, my employer has a really juicy high deductible plan that a lot of my co-workers use. Like they actually give you money to put in your HSA that covers most of your high deductible. It's a good plan. But I don't like it because it means my co-workers get to keep extra money for not going to the doctor when they are sick, and instead they come into the open plan office and cough all over the place.
I mean, I do okay, and I'd be happy to kick in a little extra money if it meant my co-workers were more likely to go to the doctor when they are sick rather than sharing the love with the office.
When you are sick, don't go to work. If there is any question of if the doctor can help, talk to the doctor. (Via phone or video chat, if necessary)
