Medicare Open Enrollment begins October 15 and runs through December 7, giving you a window each year to review your coverage and make changes for the year ahead. During this period, you can switch between Original Medicare and Medicare Advantage, change Medicare Advantage plans, or update your Part D prescription drug coverage, with any changes taking effect on January 1. Even if your current plan has worked well, it is worth checking for adjustments to premiums, drug formularies, and provider networks, since plans can change from year to year. If you have questions about how a coverage change might affect your broader retirement income and tax picture, our team is glad to talk it through with you.
