From January 1 to March 31 is open enrollment for the Medicare Advantage Program. If you didn't like the selection you made during Medicare Open Enrollment on October 15 to December 7, you are able to change your MAPD plan, which comes with Part D, during this time. Every year you get an annual notice of change letter from your healthcare carrier. If you don't read that, you might not realize what the changes are until they go in effect on January 1. If your drug prices have changed, or your network provider has changed, this allows you to correct that. Dan Redler, CEO, and Dan Leary, COO, of We Speak Medicare explain why the enrollment period exists and how it works.
