What is Medicare?

Medicare is the federal health insurance program for people who are 65 or older, certain
younger people with disabilities, people with end-stage renal disease (permanent kidney
failure requiring dialysis or a transplant, sometimes called ESRD).

Why Consider Medicare Supplement Insurance Policy

Medicare is your primary insurance coverage when you reach age 65, but it isn't designed to cover all your health care expenses. That's where a Medicare Supplemental Insurance Policy comes in.

A supplemental policy helps you manage and budget your health care expenses while giving you the freedom to choose your providers and a plan that best meets your needs. These policies help give you peace of mind.

When can I buy a Medicare Supplement Insurance policy?

The best time to buy a Supplement policy is during your 6-month Medigap Open Enrollment Period. You will generally get better prices and more choices among policies. During that time, you can buy any Medigap policy sold in your state, even if you have health problems.


This period automatically starts the month you turn 65 and enroll in Medicare Part B (Medical Insurance). After this enrollment period, you may not be eligible for a Medigap policy. If you are able to buy one, it may cost more due to past or present health problems.
