Yes, you sure can. How they will treat you when you get there is a different question. Most hospitals will treat you whether you have health insurance or not. There are some, however, that may not. In that case, they would send you you to the hospital that will treat you. It also depends on what you need. If it's something minor, you may wait or they may send you to a different hospital. If it's critical, they will either treat you there or stabilize you to go to a different hospital.
Either way, they will bill you for their services and, the more serious the case, the more it will cost.
If you're considering going to the Emergency Room, you should take a moment and think about whether that's the right place to go. There are many Urgent Care centers that can help you with more minor issues like fevers, sprained ankles, and minor injuries. You'll probably get treated more quickly and it'll cost a lot less.
