This Becomes an interesting situation
No cancer surgery for smokers?
shot in gang violence no treatment?
overweight turned away
@Splinty refusing republicans treatment?
Given that I've voted Republican more than I've voted Democrat that's a weird standard.
Anyways, it's an interesting conversation.
EMTALA means that you have a legal right to emergency and pregnancy care regardless of ability to pay.
License and oath, I provide equivalent care to all patients. Sometimes I don't care for the person's personality, but I'm not going to deny them care or do less of a job getting them fixed up. Sometimes that's enough to change the relationship on its own.
There is no significant voice inside the physician industry that supports such a move.
On the other hand, policy makers in other nationalized countries do regularly discuss how to penalize users of the healthcare system. But mostly those are targeted at the product level like smoking or sugar drinks taxes. Not necessarily the individual themselves.
