You can go to planprescriber.com for more detailed information about Medigap (and other insurance) policies for each state. It includes premiums and other criteria. Best site I've seen and covers much information. ;)
I finally found the Alabama web site that has some of that information:
www.aldoi.gov/pdf/consumers/medsupcompanies.pdf
Some of the details are not exactly clear to me. I would like to see more specific info for each company that clarifies the following:
Attained age related OR Issue age...
There are different Medigap policy premiums based on your sign-up age.
1. Attained Age Rated Policy
2. Issue Age Rated Policy
3. Community Rated Policy
Is there a site that lists the Medigap insurance companies by these groups? I live in Alabama.
