John, I have never heard of any company that provides free health insurance. A few other countries have it such as Canada...but I am not aware that it is available in America.
Of course, there are free clinics in almost every city in America if you have a health issue that is not considered an emergency.
I have an almost-free health insurance plan. I started it about a year ago and I have been healthier than I ever have been in my life. You can see it here: MSAOTP.
I hope I have been of some help.
