There is no coordinated outreach program by the government. If you are on Social Security you will automatically be enrolled in Medicare A and B effective your 65th (under age 65 if on Social Security Disability for 24 months) birthday month or the month before if you were born on the 1st of the month. It is your responsibility to enroll in additional coverage including Medicare Rx plans (Part D), Medicare Supplement Plans (Medigap) or a Medicare Advantage Plan. CMS (the Center for Medicare and Medicaid services) produce an annual “Medicare and You” booklet with great information. Reading this booklet ahead of time will help you understand when to enroll and how to avoid potential lifetime late enrollment penalties.  A good Medicare advisor can walk you through these steps and help you choose a good Medicare plan to fit your needs.
