What Is a Medicare ANOC? When It Arrives and What to Do Next
ANOC stands for Annual Notice of Change. Your Medicare health or drug plan sends it each fall to explain changes in coverage, costs, and other terms that take effect in January. Look for it in September, generally by September 30, and use it to decide whether your plan will still meet your needs.
An envelope or email from your plan can be easy to set aside. The ANOC deserves a closer look: keeping the same plan name does not mean every detail stays the same next year.
For the 2027 plan year, current members should generally have received their notice by September 30, 2026. If you have not received yours, contact your plan now. Different delivery timing can apply if you are newly enrolled for October, November, or December.
Where to look for your notice
Check mail from your current plan. If you consented to electronic delivery, also check your email and member account. Look for the words 'Annual Notice of Change' and confirm that the document names your exact plan and the upcoming year.
The ANOC comes from your plan. It is not an advertisement from our agency, a bill, or a request that everyone must change coverage. If it is missing or hard to read, ask your plan for a copy or an accessible format.
Read the changes, then check your own care
- Costs: Compare premiums, deductibles, copayments, and coinsurance. For Medicare Advantage, review the medical out-of-pocket maximum and its rules.
- Coverage: Note changes to services you use, benefit limits, referrals, or other access requirements. Read the Evidence of Coverage for the full terms.
- Prescriptions: Check every medication, strength, and refill quantity against next year's drug list. Look for coverage, tier, prior authorization, step therapy, and quantity-limit changes.
- Pharmacy: Confirm your pharmacy is in network and whether it has preferred cost sharing. Compare the estimated costs for your actual prescriptions.
- Doctors and hospitals: Confirm participation for the exact plan and upcoming year with both the plan and the provider.
The ANOC is a starting point. It does not replace checking the current provider directory, upcoming formulary, pharmacy network, and full Evidence of Coverage for your situation.
Compare the full year, not just the premium
A monthly premium is only one part of your budget. Think through routine visits, prescriptions, specialist care, and the care you reasonably expect. Compare premiums plus estimated medical and prescription expenses, and understand your exposure if you need more care than expected.
Write down your top three concerns. For example: 'Can I keep my cardiologist?', 'How will my medication be covered?', and 'What would an outpatient procedure cost?' Specific questions make a review more useful than a general promise of savings.
Act before the fall enrollment deadline if a change is needed
Fall Medicare Open Enrollment, also called AEP, runs October 15 through December 7. A valid election received by the plan by December 7 takes effect January 1 of the next year. For this fall, that means December 7, 2026 for a January 1, 2027 start.
Review early enough to verify your information and resolve questions. If your current plan remains available and still meets your needs, you may not need to make a change. If the plan says it is ending, treat that nonrenewal notice separately and ask about the applicable options and deadlines.
Do not assume January's Medicare Advantage OEP will solve every issue. It has narrower eligibility and does not provide a general standalone Part D switching window for people staying on Original Medicare.

Common questions
What if I never received an ANOC?
Contact your current Medicare health or drug plan and request it. If you chose electronic delivery, check the member portal and email too. Do not assume that a missing notice means nothing is changing.
Is the ANOC the same as the Evidence of Coverage?
No. The ANOC summarizes changes for next year. The Evidence of Coverage explains the plan's full coverage terms and rules. Use both, along with the relevant directories and drug list.
Does receiving an ANOC mean I have to switch?
No. It means you should review the upcoming terms. Staying may be appropriate if the plan continues and meets your needs; a change is a personal decision after checking eligibility and alternatives.
