Why Medicare Supplement Insurance?

Having Medicare Supplement Insurance (also called Medigap) in addition to Original Medicare benefits helps to protect you from unexpected costs, allowing you to receive the care you need without worry of financial burden. Because of the guaranteed coverage protection offered during the Open Enrollment Period, it's a great option for those with pre-existing conditions as well. Plus, it allows you to continue to receive the federal Medicare benefits you’ve been paying toward throughout your working years.

 

Key advantages of Medicare Supplement Insurance:

  • Guaranteed renewability each year

As long as you pay your premium, your coverage will continue year after year and cannot be cancelled (except in specific cases, like providing inaccurate information on your application).

  • Simple, straightforward plan options

Because they are federally standardized, it’s fairly straightforward to understand and compare your options when it comes to Medigap coverage.

  • Nationwide network of doctors and specialists

Medicare Supplement enrollees can visit any doctor that accepts Medicare coverage. Doctors or hospitals that accept Medicare are required to accept all Medigap plans, regardless of insurance carrier.

  • More flexibility with treatment options. 

Some Medicare plans require you to choose a primary care physician, who has the final say on what providers you can see. Medigap plans allow you the flexibility to select any treatment option you prefer.
