Medicare Part D

Does Your 2026 ANOC Show a Tier Change? Read It

# Your Part D Drug Could Move Tiers Jan. 1 — Here's…

BERWYN, Ill. — The mailings hitting kitchen tables across town this month look like junk, but one of them is worth opening carefully. The Annual Notice of Change, or ANOC, tells Part D and Medicare Advantage members exactly how their drug coverage will look different on January 1, 2027 — and with the Part D out-of-pocket cap moving to $2,400 in 2027, those changes matter more than usual.

Every fall, insurers rework their formularies, the lists of drugs a plan covers. A medication that sat on a low tier in 2026 could move up in 2027. A pill that filled easily at the pharmacy could suddenly require prior authorization. None of this is unusual, but it can catch a Berwyn retiree off guard at the January refill counter if the ANOC goes unread.

What actually changes on a formulary

A formulary is not static. Each year, insurers can add drugs, drop drugs, move drugs between tiers, or attach new rules to them. Tiers are the pricing ladder — generics usually sit on lower tiers, brand-name and specialty drugs on higher ones. When a drug moves from, say, Tier 2 to Tier 3, the cost-sharing at the pharmacy typically goes up, even though the plan still "covers" it.

Three utilization management tools can also shift:

• Prior authorization means the plan wants your prescriber to justify the medication before it will pay.
• Quantity limits cap how many pills or doses you can get in a set time period.
• Step therapy requires you to try a lower-cost drug first before the plan will cover a more expensive alternative.

Any of these can be added, removed, or tightened for the new plan year.

Why 2027 is a bigger deal than usual

The Part D benefit itself keeps evolving. The out-of-pocket cap for covered drugs is $2,100 in 2026 and $2,400 in 2027 — once you hit it, you pay nothing more for covered prescriptions the rest of the year. The maximum deductible any Part D plan can charge is $615 in 2026 and $700 in 2027. And the old coverage gap ("donut hole") is officially gone as of 2025, replaced by a three-phase structure: deductible, initial coverage, and catastrophic.

There is also the Medicare Prescription Payment Plan, an optional program that lets you spread your drug costs across the calendar year in monthly installments instead of paying big amounts at the pharmacy counter. It doesn't lower what you owe, but it evens out the timing.

For higher-income beneficiaries, IRMAA surcharges kick in above $109,000 in income for a single filer in 2026, adding to the base Part D premium.

How to read the ANOC without losing a Saturday

The ANOC is long, but the sections that matter most for drug coverage are short. Look for:

1. Changes to the drug list. Is your medication still on it? Did it move tiers? 2. Changes to prior authorization, step therapy, or quantity limits. These are usually flagged with a note or symbol next to the drug name. 3. Changes to the pharmacy network. A preferred pharmacy this year may be standard next year, which affects your cost-sharing. 4. Changes to premium and deductible. Compare year over year, not just the new number in isolation.

If a drug you take is affected, that is your signal to compare plans during the Annual Enrollment Period, October 15 through December 7. Coverage you choose then begins January 1.

The transition fill safety net

If January arrives and you're still on a plan whose formulary changed on you, don't panic at the pharmacy. Part D plans are required to provide a transition fill — typically a one-time supply — for members whose current drugs are no longer covered or now have new restrictions. This buys you time to work with your prescriber on either a formulary exception request or a switch to a covered alternative.

You also have the right to request a coverage determination or exception if you believe you need a non-preferred drug for medical reasons. Your prescriber can support that request.

Local context for Berwyn

Berwyn is in Cook County, where Medicare beneficiaries generally have a wide selection of stand-alone Part D and Medicare Advantage plans with drug coverage to choose from during AEP. For 2027, CMS Landscape files list 58 Medicare Advantage plans from 11 carriers in the county, with 52 plans continuing, 6 new, 17 not returning, and 9 renamed; Clear Spring Health is not offering plans in the county next year. The exact plan options and their formularies are set at the county level, not the city level, so a neighbor a few blocks away in Cicero or Oak Park sees the same slate of choices you do.
