Can you explain the “monthly cost” for a Medigap policy that is listed in the Medicare Plan Finder?

The Medicare Plan Finder offers information about the types of Medigap policies available by zip code.

Pick the type of plan you want to investigate, such as Plan G. Click on view policies and you'll see a range of monthly premiums, such as $140-$292.  If you update your specifics – age, sex, tobacco use – you'll see a more specific number. But, remember, this is very general information. Contact a company representative or agent to discuss your situation.
