There are some vision and dental plans advertised.. I can not tell you much about 'em.. I have State of Michigan Blue Cross, which includes vision, and a Dental plan (I think Delta) as well.
Neither plan is all that good though.. Some of the advertised plans are better.
Thankfully I have State of Michigan Blue Cross (This is really the state providing my insurance, Blue Cross is only a "Clearing house/administrator" for the state, I am retired state employee)
I spent a bit of time in the body shop (Hospital) a couple months ago, a little over 40,000 and that's JUST the room and board.. It does not count doctors.
MAN am I glad I had insurance.
