Medicare’s 2012 Open Enrollment Period will run from October 15 through December 7. During this period, people with Medicare can change their Medicare health and prescription drug plan coverage options. Changes that are made on or before December 7 will take effect on January 1, 2012.
If you are happy with your Medicare plan, there is no need to take action. The official Medicare site has done a great job explaining the basics in a user-friendly way.
A word of caution: Private Medicare Advantage Plans (Part C) can start marketing to you as of October 1. These are private HMO insurance plans that contract to Medicare to provide your services; they are not traditional Medicare. Before you make any decisions or changes to your Medicare, do your research. Don’t let a fancy marketing brochure fool you.
