If you are on a Medicare Advantage or Part D plan, something important is landing in your mailbox this month. Every plan is required to send your Annual Notice of Change by September 30, and it spells out exactly how your coverage is changing on January 1.
Most people glance at it and set it aside. That is a costly habit. The ANOC is the only document that tells you, in plain numbers, what next year will cost you before you have to decide whether to keep the plan.
What the ANOC Actually Is
The Annual Notice of Change is a side by side comparison: this is what your plan charged and covered in 2026, and this is what it will charge and cover in 2027. It usually arrives with the Evidence of Coverage, a much longer document that spells out the full legal terms of the plan.
The ANOC is the one you need to read. It is short, and every line in it is a change.
Five Things to Check Before You File It Away
- Your monthly premium. A plan that was $0 this year is not automatically $0 next year. Check the number, not your memory of it.
- Your maximum out of pocket. On a Medicare Advantage plan this is the ceiling on what you can spend in a bad year. If it moved up by a few thousand dollars, that is the single biggest change in the whole document.
- Your drug list. Plans drop medications, move them to higher cost tiers, and add rules like prior authorization or step therapy every year. Look up each prescription you actually take, by name and dosage.
- Your provider and pharmacy network. Doctors and hospital systems leave networks. So do pharmacies. If your preferred pharmacy became a standard pharmacy, your copays went up without the plan changing a single benefit number.
- Copays for the things you actually use. Primary care, specialists, imaging, outpatient surgery, and hospital stays. The extras like dental and vision matter too, but these are what drive real spending.
What Is Changing Across All Part D Coverage in 2027
Some changes are not your plan’s doing. Medicare sets the outer limits every year, and two of them are moving for 2027:
- The maximum Part D deductible a plan can charge rises to $700, up from $615 in 2026.
- The annual cap on what you pay out of pocket for covered prescriptions rises to $2,400, up from $2,100 in 2026.
The cap is still real protection, and it is far better than the old system with no ceiling at all. But if you take expensive medications, budget for the higher number.
What Happens If You Ignore It
Nothing dramatic, and that is the problem. You stay enrolled in the same plan automatically, under the new terms, whatever they are. Nobody calls to warn you. You find out in February when a prescription that cost $10 now costs $95, or when your specialist tells you they are no longer in the network.
Open Enrollment runs October 15 through December 7. That is your window to move, and once it closes most people are locked in for the year. Here is the full prep checklist to have ready before it opens.
