Your Medicare Annual Notice of Change Arrives by Sept. 30: How to Read It Before Open Enrollment

Your Medicare Annual Notice of Change (ANOC) for 2027 must reach you by September 30, 2026 — and for many adults 50+ and older, it is the most important piece of mail of the year. If you have a Medicare Advantage or Part D prescription drug plan, this short document lists every change to your premiums, copays, deductibles, drug list and provider network for next year. Reading it now gives you two full weeks to prepare before Medicare Open Enrollment opens on October 15 and runs through December 7, 2026.

This year, experts say the notice deserves more attention than usual. Several cost shifts are coming in 2027, and plans that were a good fit this year may not be next year.

What Is Changing in Medicare for 2027?

Early reporting on 2027 plans points to a few big themes:

• Higher drug costs and premium pressure: Analysts expect some Part D and Medicare Advantage plans to raise premiums or change which drugs they cover.
• A premium subsidy is ending: A federal program that lowered stand-alone Part D premiums (by about $16 a month in 2026) is ending, which could push some premiums up.
• A higher out-of-pocket drug cap: The Part D out-of-pocket cap was $2,100 in 2026 and is estimated at about $2,400 for 2027.
• More negotiated drug prices: Another 15 drugs — including some GLP-1, diabetes and cancer medications — are slated for lower negotiated prices.

What Should You Look For in Your ANOC?

You do not need to read every page. Focus on these five sections:

1. Monthly premium

Compare 2027 to 2026. Even a $15 monthly increase adds up to $180 a year.

2. Drug formulary (your medication list)

Check that every drug you take is still covered and note any change in its “tier.” A move to a higher tier can mean a much larger copay.

3. Deductibles and copays

Look for changes to your drug deductible, specialist copays and hospital costs.

4. Provider and pharmacy network

If you are in a Medicare Advantage plan, confirm your doctors, hospital and preferred pharmacy are still in network.

5. Extra benefits

Dental, vision, hearing and fitness perks often shrink quietly. If you rely on them, check the fine print.

What If Your Notice Doesn’t Arrive?

If you haven’t received your ANOC by early October, call the member services number on your plan card and ask for it, or log into your plan’s online portal. Don’t wait — open enrollment is the main window each year to switch plans without restrictions.

How Do You Compare Plans Before October 15?

• Make a medication list with doses and how often you take each drug.
• Use the Medicare Plan Finder at Medicare.gov once 2027 plan data goes live in October.
• Get free, unbiased help from your State Health Insurance Assistance Program (SHIP).
• Be wary of cold calls — Medicare will not call you to sell a plan.

Bottom line: Fifteen minutes with your ANOC now could save you hundreds of dollars — and a lot of stress — in 2027.
