If you pay Social Security (hey, don't know how many "anonymous" people are out there), you're covered with disability (if you can live on a pittance). Supplemental Security Income, or SSI and disability are our federal right. It takes 3 appeals however to be accepted.....I helped many brain tumor terminal patients get it but the standard response is always to deny it, 3 times before it's granted.
As far as major medical, my advice is to nix it. Rules in states of "no-fault", or most areas the favors are legislated on the side of the insurers. Claims for major medical are always short-changed leaving our pockets to cover the incedentals and that leads to bankruptcy. If we're not covered, federal rules dictate that treatment centers MUST eat the expenses. If we DO have major med, we assume all co-payments and additional charges not outlined by the policy. This sucks, but that's America. They can and will sue to get your home, trucks, business, and your first born.
I recommend a standard liability policy, emergency care, and comprehensive to cover property and theft. If you employ occassional help, it has to be contract.
On cancers or other major mishaps (hey, were in the business) to have an insurance contract is actually a limiting factor on quality of care - all institutions will dictate treatment options limited to coverage, not what's appropriate. From experience, I suggest not having cancer coverage, it'll break you if it happens. If you get the big "c", the best possible option is to qualify for clinical trial at a regional cancer center, not a private hospital which would be the case if you have insurance coverage. Private hospital cancer treatment programs have unacceptable mortality rates and higher than reasonable billing practices, whether you live or die.
Or, you can just do what I do......
