The hospital has a duty to provide you medical treatment in cases of emergencies and cannot deny you simply because you don’t have insurance. If you have been denied treatment, you can sue the hospital for damages or seek an injunction to prevent the hospital from denying you and others emergency treatment. However, pursuant to Obamacare, everyone must have health insurance either through a private provider or through a state or federal assisted program. If you don’t have insurance you must pay a tax equal to 1% of your income in 2014 and 2.5% in 2016.
