Your Annual Notice of Change: 5 Quick Checks Before December 7

Every fall, your health or drug plan mails you a document called the Annual Notice of Change — ANOC for short. It had to reach you by September 30 — and if you do nothing, your plan simply renews on the new terms it describes. The notice is easy to ignore because it looks like routine paperwork. It is not. Fifteen minutes with this checklist — premium, deductible, drugs, doctors, and extra benefits — can save you from a January surprise.

What Is the Annual Notice of Change?

The ANOC is your plan's official list of what changes on January 1, 2027: the premium, the deductible, copays, the drug list, and the provider network. Medicare requires every Medicare Advantage plan and every Part D drug plan to send it, and the deadline is the same every year: September 30. If yours never arrived, call your plan and ask for a copy — and if you are comparing options during Open Enrollment (October 15 to December 7), the ANOC is the document to compare against.

Check 1: Your Premium (Minutes 1–3)

Find the 2027 monthly premium in the notice and write it next to what you pay now. A few dollars a month is easy to shrug off, but do the yearly math: $8 more a month is $96 a year, every year, for the same plan. Then check whether the notice mentions any change to extra charges — some plans adjust the Part B premium give-back or add a new supplemental fee. If the premium rose and nothing else about the plan improved for you, that is your first reason to shop around before December 7.

Check 2: Your Deductible and Copays (Minutes 4–6)

Next, compare the deductible. Check the 2027 deductible — the amount you pay before coverage starts — for both medical care and, if your plan includes drugs, prescription coverage. Then look at the copays for the visits you actually use: primary care, specialists, urgent care, and the emergency room. Small copay increases on a service you use every month add up faster than a premium increase. If you see a number you do not recognize, the ANOC summary chart usually puts the current year and next year side by side.

Check 3: Your Medications — Still Covered, Same Tier? (Minutes 7–10)

This is the check that matters most, and — for drug plans — the one most likely to change:

• Still on the list? Confirm every drug you take is still on the plan's 2027 drug list (the formulary).
• Same tier? A drug that moves to a higher tier can jump from a small copay to a percentage of the full price.
• New restrictions? Are there new rules — prior authorization, step therapy, or quantity limits — attached to any of your medications?

If one of your regular prescriptions moved or vanished, that alone can justify switching plans. Bring your medication list to this check; do not rely on memory.

Check 4: Your Doctors and Pharmacy (Minutes 11–13)

Plans renegotiate with doctors, hospitals, and pharmacies every year, and the ANOC flags the big network changes. Confirm that your primary care doctor, your key specialists, and your usual hospital are still in the network for 2027, and that your pharmacy remains a preferred pharmacy — the difference between a preferred and a standard pharmacy can be several dollars on every prescription. If a provider is leaving the network, the notice may explain your options, including any transition period.

Check 5: Your Extra Benefits (Minutes 14–15)

Finally, scan the extra benefits: dental, vision, hearing, fitness, over-the-counter allowances, and transportation. These are the benefits plans trim first when costs rise, and they are often the reason people chose the plan in the first place. If an allowance you actually use was cut, put a dollar value on the loss and add it to your premium and deductible changes. Sometimes a plan with a slightly higher premium is the cheaper plan once the extras you use are counted honestly.

What If You Find a Red Flag?

You have until December 7 — the end of Medicare Open Enrollment — to switch to a plan that fits better, with the new plan starting January 1, 2027. Compare total costs at Medicare.gov/plan-compare, which uses your drugs and your doctors, and remember that help is free: your State Health Insurance Assistance Program (SHIP) offers one-on-one counseling at no cost. Bring your ANOC with you; it is exactly the document a counselor will want to see first.

One more date to keep in mind: if you are in a Medicare Advantage plan, a second window — the Medicare Advantage Open Enrollment Period — runs January 1 to March 31, when you can switch Advantage plans or move back to Original Medicare. The December 7 deadline in the ANOC letter is the main one for most people, but it is not quite the last word for Advantage members.

Frequently Asked Questions

What happens if I ignore my Annual Notice of Change?
Nothing dramatic — and that is the risk. Your plan renews automatically on its 2027 terms: new premium, new drug list, new network, whether or not those terms still suit you.

When do the changes in the notice take effect?
January 1, 2027. The ANOC describes next year's terms, not changes to your current coverage.

Is the ANOC the same as the Evidence of Coverage?
No. The ANOC summarizes what is changing next year. The Evidence of Coverage is the full rulebook for the plan. Both were due to reach you by September 30. For a quick review, the ANOC is the one to read first.

I found a problem. When is my deadline to switch?
December 7, the end of Open Enrollment. A plan you choose by then starts on January 1, 2027.

Key Takeaway

Your Annual Notice of Change arrived by September 30, and silence is a decision: do nothing and your plan renews on its 2027 terms. Fifteen minutes is enough to check the five things that decide whether it still fits — your premium, your deductible and copays, your medications and their tiers, your doctors and pharmacy, and your extra benefits. If any check raises a red flag, compare total costs on Medicare.gov or sit down with a free SHIP counselor before December 7, while the choice is still yours.
