Evidence of Coverage (EOC) is the list of Medicare Advantage or Part D plan costs and benefits that will take effect on January 1 of the following year. You should receive an EOC from your plan in the fall. Review the EOC to see if the plan will meet your health care needs for the following year. The EOC is typically mailed with the plan’s Annual Notice of Change (ANOC), which is a notice informing you of plan changes that will take effect the following year.
