The Annual Notice of Change (ANOC) is the notice you receive from your Medicare Advantage or Part D plan in late September. This notice gives a summary of any changes in the plan’s cost and coverage that will take effect January 1 of the next year. Review this notice to see if your plan will continue to meet your health care needs in the following year. If you do not receive an ANOC from your plan, you should contact your plan. The ANOC is typically mailed with the plan’s Evidence of Coverage (EOC), which is a more comprehensive list of the plan’s cost and benefits for the upcoming year.
