Medicare Part D

Your Part D Drug Is Covered Now. Will It Still Be Jan. 1?

Georgetown, Del. — If you take a prescription covered by a Medicare Part D plan, the version of that coverage you have today is not guaranteed to be the same on January 1. Every fall, Part D plans — both stand-alone drug plans and the drug coverage built into most Medicare Advantage plans — refresh their formularies (the list of drugs they cover) and the rules around them. That is why the envelope arriving in your mailbox this September and October matters more than it looks.

The document inside is called the Annual Notice of Change, or ANOC. It spells out what will be different about your plan in 2027. And with the Part D out-of-pocket cap set at $2,400 for 2027 and the maximum deductible at $700, small changes to how your specific drug is treated can add up quickly.

What actually changes on a drug list each year

A Part D formulary is not a static document. Plans review it every year and can:

• Add or remove drugs.
• Move a drug to a different tier (tiers usually run from preferred generics up to specialty drugs, and the tier affects your cost share).
• Add or lift utilization management rules like prior authorization, step therapy, or quantity limits.
• Change preferred pharmacies or mail-order arrangements.

None of this means your plan is "bad." It means Part D is a yearly contract, and the terms reset in January.

Tiers, in plain English

Most Part D plans sort covered drugs into tiers. Lower tiers generally have lower cost sharing; higher tiers cost more out of pocket. The same drug can sit on Tier 2 in one plan and Tier 3 in another — and it can move between tiers from one year to the next within the same plan.

When you read your ANOC, look for a section comparing your drugs' 2026 tier to the 2027 tier. A jump of even one tier can meaningfully change what you pay at the pharmacy counter.

Prior authorization, step therapy, and quantity limits

These are the three most common "utilization management" tools, and they trip people up because a drug can still be covered — just with strings attached.

• Prior authorization (PA): Your doctor has to get the plan's approval before the prescription is filled. The plan wants to confirm the drug is medically necessary for your condition.
• Step therapy: The plan asks you to try a lower-cost or preferred drug first. If that doesn't work, you can "step up" to the drug you and your doctor originally wanted.
• Quantity limits: The plan caps how many pills, inhalers, or doses you can get in a set period, usually based on FDA-approved dosing.

If any of these rules are new for your drug in 2027, the ANOC will say so. Your doctor's office can often submit the paperwork, but it takes time — which is why catching it in October is better than finding out at the pharmacy in January.

How to actually read the ANOC

The ANOC is not light reading, but you don't have to read all of it. Focus on:

1. The premium and deductible for 2027. 2. The formulary changes section — specifically, any drug you personally take. 3. The utilization management notes — is there a new PA, step therapy, or quantity limit on one of your medications? 4. The pharmacy network — is your regular pharmacy still preferred?

Put your current prescription bottles on the table, open the ANOC, and check them one by one. If something is changing, you have from October 15 through December 7, 2026 — the Annual Enrollment Period — to compare and switch plans for 2027. Medicare Advantage members also have a second window, January 1 through March 31, to make one change.

What if you're already on the drug and the plan drops it?

Part D plans generally must provide a transition fill — typically a one-time, temporary supply — when a new plan year starts and your drug is no longer covered or has new restrictions. That gives you and your prescriber time to either switch to a covered alternative or request an exception.

You also have the right to ask for a formulary exception if your doctor believes the covered alternatives won't work for you. And if drug costs are a strain, the Medicare Prescription Payment Plan — an option that started in 2025 — lets you spread your out-of-pocket drug costs across monthly payments instead of paying all at once at the pharmacy.

What this looks like around Georgetown

Georgetown is in Sussex County, where Medicare beneficiaries typically have a wide selection of stand-alone Part D plans and Medicare Advantage plans that include drug coverage. Availability and plan details are set at the county level, so two neighbors in Sussex County will see the same menu of options — but the plan that fits one person's drug list may not fit the other's.
