Medicare Part D

Your Part D drug list can look different on Jan. 1 — here's how to spot it in Cedar Hill

CEDAR HILL, Texas — The envelope showing up in mailboxes across Cedar Hill this fall is easy to overlook, but it decides whether the prescription you filled in October will cost the same, cost more, or need extra paperwork in January. It's called the Annual Notice of Change, or ANOC, and every Medicare Part D plan and Medicare Advantage plan with drug coverage has to send one by the end of September.

The ANOC is the plan's way of saying: here is what will be different next year. And because Part D formularies — the lists of covered drugs — can shift from one plan year to the next, the letter arriving this fall is worth reading before the Annual Enrollment Period closes on Dec. 7.

Why a "covered" drug can still change

A formulary is not a fixed list. Plans update it each year — and, within limits set by CMS, sometimes mid-year — as new drugs come to market, generics arrive, or manufacturers change prices. That means a medication you took all of 2026 may still be on the list in 2027, but sitting in a different spot with different rules.

Four changes are worth watching for in the ANOC:

Tier changes. Most Part D plans sort covered drugs into tiers, usually five or six of them. Lower tiers generally mean lower cost sharing; higher tiers, more. When a drug moves up a tier, the plan still covers it — but your share of the cost can change.

Prior authorization. This means the plan wants your doctor to send information showing the drug is medically necessary before it will pay. Nothing about the drug itself has changed; the paperwork has.

Quantity limits. The plan caps how much you can get in a set time — say, 30 tablets per 30 days. If the limit tightens, or shows up on a drug that didn't have one before, you'll see it in the ANOC.

Step therapy. The plan asks you to try a lower-cost alternative first. If it doesn't work, you can "step up" to the drug you and your doctor originally wanted.

Together, tiers, prior authorization, quantity limits and step therapy are called utilization management. They're legal tools, but they can catch people off guard at the pharmacy counter in January.

How to actually read the ANOC

Cedar Hill is in Dallas County, where 75 Medicare Advantage plans from 12 carriers are offered for 2027, alongside stand-alone Part D plans. Each ANOC follows the same general shape. A few pages in, you'll find a section comparing this year's costs and rules to next year's, side by side.

Do this:

1. Find each of your regular prescriptions in the plan's 2027 formulary. The ANOC often points to the online drug list; the printed booklet is called the Evidence of Coverage. 2. Check the tier next to each drug. Note whether it went up, down or stayed the same. 3. Look for the letters PA, QL or ST next to the drug name. Those flag prior authorization, quantity limits or step therapy. 4. Read the premium and deductible page. These can change year to year, independent of what happens to your drugs.

If any of those has moved in a direction you don't like, you have until Dec. 7 to switch to a different Part D plan or a Medicare Advantage plan with drug coverage for 2027. People already in a Medicare Advantage plan get a second window — the Medicare Advantage Open Enrollment Period — from Jan. 1 through March 31.

What's actually new for 2027

A few program-level facts frame every plan's numbers for the coming year:

• The Part D out-of-pocket cap is $2,100 in 2026. Once your covered drug spending hits that, you pay $0 for covered drugs the rest of the year.
• The maximum Part D deductible is $700 in 2027, up from $615 in 2026. Plans can charge less, but not more.
• The coverage gap ("donut hole") is gone as of 2025. Part D now has three phases: deductible, initial coverage, and catastrophic.
• The Medicare Prescription Payment Plan is available. It doesn't lower what you owe, but it lets you spread your out-of-pocket drug costs across the calendar year in monthly bills instead of paying the pharmacy up front.
• IRMAA surcharges on Part B and Part D premiums begin above $109,000 in income for a single filer in 2026.

None of these change what's on your plan's formulary — but they do change the math around it.

What to do if a drug you take is affected

If your ANOC shows a change that worries you, you have options:

• Talk to your prescriber. Sometimes a therapeutically similar drug on a lower tier will work just as well. Sometimes it won't, and that's worth knowing early.
• Ask the plan for an exception. You or your doctor can request that the plan cover a non-formulary drug, waive step therapy, or move a drug to a lower tier for a medical reason. There's a formal process, and a timeline.
• Use a transition fill. If you're new to a plan or your drug is newly restricted, most plans will fill a short-term supply early in the year so you have time to work things out.
• Shop other plans. Medicare's Plan Finder at medicare.gov lets you enter your drugs and pharmacy and see how each of the 75 Medicare Advantage plans and the stand-alone Part D plans available in Dallas County for 2027 would handle them.
