Medigap insurance companies are everywhere. This Medigap coverage pays for the health care needs that Medicare doesn't pay for.
There are so many different levels of coverage with most insurance companies. Basic plans are standard, but you might opt to pay more for additional coverage based on your own need.
Choosing the right Medigap coverage is very confusing. Please take your time. Print out the levels of benefits and compare to what you've used this past year... but remember, that doesn't mean your health stays as is this next year.
This is a list of Health Care companies with Medigap Plans for Michigan (my home state). They may not be available in all states. There are other plans out there too.. this is simply one of many resources available to you.
