Will health insurance cover existing medical bills?

I have a kidney stone that is unbearable and I want to get it checked out. I just applied for health insurance but I have to wait to find out if it’s approved. Can I go to the hospital today and have it be covered when my insurance application is approved?

Where can I find recommendations for medical providers in my health insurance network?

I recently changed jobs, and moved to a new city. With new health insurance, and so many in-network providers, I’d like to know if there’s a website or something where I can see personal reviews on doctors?

Are all working Americans suppose to be rich…. & have medical health insurance from working at McDonald?
