When my previous company shut down back in 2001 we used Blue Cross Blue Shield's "Short Term" coverage for a few months which was less than a quarter the price of our ridiculously quoted COBRA price for our HMO at the time. BCBS had a variety of deductible amounts we could choose, and would have been there if something major had happened over the few months when we did not have employer provided coverage (luckily no major medical emergencies occurred). You can use their "Get A Quote" feature at:
Anthem Visitors
to check the many different options that Blue Cross can provide. Plus you know Blue Cross coverage is accepted just about everywhere.
