What are Medicare Supplements?
Medicare supplement insurance is also called “Medigap” or “MedSupp.” It is private insurance designed to fill gaps in Medicare coverage and is sold by many companies.

When can I buy a Medicare Supplement?
Every new Medicare recipient who is age 65 or older has a guaranteed right to buy a Medicare supplement policy during a six-month “open enrollment.” A company cannot reject you for any policy it sells, and it cannot charge you more than anyone else your age. Your open enrollment period starts when you are age 65 or older and enroll in Medicare Part B for the first time. It ends 6 months later.
