Medicare Part D

Jacksonville Part D in 2027: what the ANOC quietly tells you about your drugs

JACKSONVILLE, Fla. — Every fall, an envelope shows up in Duval County mailboxes that most people barely skim. It is called the Annual Notice of Change, or ANOC, and for anyone with a Medicare Part D drug plan or a Medicare Advantage plan with drug coverage, it is the single most important piece of mail you will get before the Annual Enrollment Period closes on Dec. 7.

The ANOC is not marketing. It is your plan telling you, in writing, what will be different about your coverage on Jan. 1, 2027 — including which of your prescriptions may sit on a different tier, need prior approval, or come with a new quantity limit. Reading it carefully now is how you avoid a surprise at the Jacksonville pharmacy counter in January.

What the ANOC actually is

The ANOC is a required document. Every Medicare Advantage and standalone Part D plan has to send it to current members ahead of the fall enrollment window. It compares your 2026 coverage to your 2027 coverage, side by side. If your premium is changing, if the deductible is changing, if the pharmacy network is changing, or if your drug list is changing, that is where you will find it.

Jacksonville is in Duval County, where Medicare beneficiaries choose from a full slate of standalone Part D plans and Medicare Advantage plans with drug coverage. No matter which plan you are in, the ANOC format is broadly similar — and the drug-list section is usually the part worth the most careful reading.

How Part D drug lists can change

A plan's list of covered drugs is called a formulary. Formularies are reviewed and refiled with Medicare every year, and four things can shift from one plan year to the next:

Tier changes. Most Part D plans sort covered drugs into tiers, and each tier has its own cost-sharing. A medication that was on a lower tier this year may move up next year, which usually means you pay more for the same pill. It can also move down.

Prior authorization. A drug that filled without any paperwork in 2026 may require your prescriber to submit a prior authorization form in 2027 before the plan will pay for it.

Step therapy. The plan may require you to try a preferred (often lower-cost) alternative first, and only cover the original drug if the alternative does not work or is not tolerated.

Quantity limits. The plan may cap how much of a drug it will cover in a given period — for example, a set number of pills per 30 days.

A drug can also be removed from the formulary entirely, though federal rules require plans to give notice and, in many cases, offer a transition supply for continuing members while you and your doctor sort out next steps.

How to actually read the notice

Pull out the ANOC and go straight to the drug coverage section. Then work through this short checklist with your current prescription list in hand:

• Is every drug you take still on the formulary for 2027?
• Has the tier changed on any of them?
• Are any of them newly marked "PA" (prior authorization), "ST" (step therapy), or "QL" (quantity limit)?
• Is your preferred Jacksonville pharmacy still in the plan's preferred network? Preferred versus standard network status can change how much you pay even when the drug itself has not moved.
• Has the deductible or the plan's tier cost structure changed in a way that affects the drugs you actually take?

If anything looks off, you have until Dec. 7 to switch to a different Part D or Medicare Advantage plan for 2027. If you are in a Medicare Advantage plan, you also have the Jan. 1 – March 31 Medicare Advantage Open Enrollment Period to make one additional change.

The Part D rules that still apply in 2027

Some of the biggest recent changes to Part D are structural, not plan-by-plan. The coverage gap — what people used to call the donut hole — was eliminated in 2025, and Part D now works in three phases: deductible, initial coverage, and catastrophic. The maximum Part D deductible any plan can charge is $615 for 2026 and $700 for 2027. The annual out-of-pocket cap on covered drugs is $2,100 in 2026 and $2,400 in 2027; once you hit the cap, you pay nothing more for covered drugs the rest of the year. The Part D national base beneficiary premium — a formula input, not what any plan charges — is $41.33 for 2027. CMS publishes the 2027 Part B premium, Part B deductible, and IRMAA income brackets later in the fall, usually in November.

There is also the Medicare Prescription Payment Plan, an optional program that lets you spread your covered drug costs across monthly payments instead of paying the full amount at the pharmacy. It does not lower what you owe overall — it just smooths when you pay it. You can opt in through your plan.

Higher-income beneficiaries should also be aware of IRMAA, the income-related surcharge that applies to Part B and Part D premiums. For 2026, IRMAA begins above $109,000 in income for a single filer.

If your drug is being dropped or restricted

You have options. Your prescriber can request an exception from the plan, asking it to cover the drug or waive the utilization management rule. If the exception is denied, there is a formal appeals process. And if a plan removes a drug you were already taking, federal transition rules generally require it to provide a temporary supply so you are not cut off while you work out a longer-term answer.

You do not have to figure this out alone. In Florida, SHINE (Serving Health Insurance Needs of Elders) is the state's SHIP program and offers free, unbiased counseling to Medicare beneficiaries, including Jacksonville-area residents. You can also call 1-800-MEDICARE or use the Plan Finder tool at medicare.gov, which lets you enter your specific drugs and pharmacy and compare how different plans would handle them for 2027.
