Medicare Part D

Same drug, new rules in January? What Dearborn's ANOC really says

# Same drug, new rules in January? What Dearborn's ANOC really…

DEARBORN, Mich. — The envelopes are landing in mailboxes across east Wayne County right now. If you have a Medicare Part D drug plan or a Medicare Advantage plan with drug coverage, your insurer is required to send you an Annual Notice of Change, or ANOC, by the end of September each year. It spells out what will be different about your coverage starting January 1, 2027 — and for prescription drugs, "different" can mean a lot of things beyond price.

Every fall, plans update the list of drugs they cover, called a formulary. A medication you take today may sit on a different tier next year, need approval before the pharmacy can fill it, or come with a new monthly quantity limit. None of that shows up at the counter until January. The ANOC is your heads-up.

What actually changes on a Part D drug list

Plans refresh their formularies every year, and the changes fall into a few buckets:

Tier changes. Most plans sort drugs into tiers — usually preferred generics, generics, preferred brands, non-preferred, and specialty. A drug moving from a lower tier to a higher tier generally means a higher cost share, even if the plan's overall premium looks similar.

Prior authorization (PA). Your plan may start requiring your doctor to submit paperwork explaining why you need a specific medication before it will be covered.

Step therapy. The plan may require you to try a less expensive drug first. If it doesn't work, you can "step up" to the one you originally wanted.

Quantity limits. The plan may cap how many pills, inhalers, or units you can get in a set period.

A drug can be dropped from the formulary entirely, too — though federal rules require plans to notify affected members and, in many cases, provide a transition supply.

How to read the ANOC without getting lost

The ANOC is long, but you only need a few pages to protect yourself:

1. Find the "Changes to the Drug List" section. Look up each medication you actually take. Note any tier change or new restriction (PA, step therapy, quantity limit). 2. Check the cost-sharing table. Even if your drug's tier didn't move, the cost share for that tier may have. 3. Look at the pharmacy network. Preferred pharmacies can change year to year, and using a non-preferred one can raise your out-of-pocket costs. 4. Compare the summary of benefits page-by-page with last year's. The ANOC is designed as a side-by-side.

If a drug you rely on has a new hurdle, that is your signal to either work with your prescriber on the paperwork or use the Annual Enrollment Period to shop.

The transition fill: a short runway, not a solution

If you're a continuing member and a drug you've been taking is no longer covered — or now has a restriction you didn't have before — Medicare rules generally require your plan to cover a temporary transition supply early in the new year (typically at least a one-month fill within the first 90 days at retail). That gives you time to talk with your doctor about alternatives or file an exception request. It's not permanent coverage, so don't wait.

2027 program facts worth knowing

A few numbers apply across every Part D plan, no matter which one you pick:

• The Part D out-of-pocket cap is $2,100 in 2026. Once you hit it, you pay $0 for covered drugs the rest of the year.
• The maximum deductible is $615, though many plans set theirs lower.
• The old coverage gap ("donut hole") is gone as of 2025 — Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments at no extra charge. You have to opt in.
• IRMAA surcharges on Part B and Part D premiums begin above $109,000 in income for a single filer in 2026.
