A Medicare Annual Notice of Change, often called an ANOC, explains important changes to a Medicare Advantage or Medicare drug plan for the next coverage year.
Why does the ANOC matter?
It can show changes in costs, coverage, benefits and other plan details that may affect whether your current plan still fits your needs next year.
What should you compare in the notice?
Look for changes to premiums, deductibles, copays, coinsurance, covered services, prescription drug coverage, pharmacy rules and other plan terms that apply to you.
Should you review it even if you like your current plan?
Yes. CMS advises people in Medicare health or prescription drug plans to review the plan materials they receive each year, including the Annual Notice of Change and Evidence of Coverage.
What if something important changed?
Make a short list of the changes that affect you, then compare your current plan with available alternatives using Medicare.gov or licensed help before making a decision.
