Medicare Part D
Riverton readers: how to spot a Part D drug list change before January 2027
RIVERTON, Utah — The envelopes are landing in mailboxes across Salt Lake County right now. If you have a Medicare Part D drug plan or a Medicare Advantage plan with drug coverage, your Annual Notice of Change (ANOC) should have arrived by the end of September. It is easy to set aside, but it is the single best warning you have that a medication you take could cost more, sit on a different tier, or need extra paperwork starting January 1, 2027.

- Your ANOC arrives each fall and shows how your plan's drug list, tiers, and rules will change for the coming year.
- A drug can stay "covered" but move to a higher tier or add prior authorization, quantity limits, or step therapy — all of which affect what you pay or how you fill it.
- The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027. The maximum Part D deductible is $615 in 2026 and $700 in 2027. The coverage gap is gone.
- If something changes, you can switch plans during Annual Enrollment (Oct. 15 – Dec. 7) or use Medicare Advantage Open Enrollment (Jan. 1 – Mar. 31) for MA plans.
Here is what to look for, in plain language, before the Annual Enrollment Period closes on December 7.
Why a covered drug can still change on you
Every Part D plan uses a formulary — a list of the drugs it covers. That list is not frozen. Insurers update formularies each plan year, and CMS reviews the changes. A drug you filled easily in 2026 might, in 2027, sit on a different tier, require your doctor to send extra information, or come with a monthly quantity cap.
None of that means the drug is no longer covered. It means the terms of coverage have shifted. That is exactly what the ANOC is designed to flag.
The four changes most likely to catch you off guard
Tier changes. Most plans sort drugs into tiers (often 1 through 5 or 6). Lower tiers usually mean lower cost sharing. If your medication moves from, say, a preferred tier to a non-preferred tier, your share of the cost can go up even if the plan's overall pricing structure looks the same.
Prior authorization. Your plan may now require your prescriber to submit clinical information showing the drug is medically appropriate before the pharmacy can fill it. If you do not know this is coming, you can find out at the counter.
Quantity limits. The plan caps how many pills, inhalers, or doses it will cover in a set period. If your prescription exceeds the new limit, your prescriber can request an exception, but it takes time.
Step therapy. The plan asks you to try a lower-cost or preferred drug first. If that drug does not work or is not appropriate, your prescriber can request coverage of the original medication.
How to actually read the ANOC
The ANOC is usually a slim booklet with a side-by-side "this year vs. next year" layout. Skim past the general benefit summary and go straight to the drug coverage section. Look for:
- A list of drugs being removed, added, or moved between tiers.
- Any new utilization management rules (the terms above).
- Changes to the pharmacy network — especially if you use a specific pharmacy in Riverton or nearby Bluffdale, Herriman, or South Jordan.
- Changes to mail-order or preferred pharmacy status.
Then pull up your current medication list and check each one against the changes. If a drug you take is on the change list, that is your cue to act — not panic.

What 2027 changes for everyone on Part D
A few program-level facts apply no matter which plan you have:
- Out-of-pocket cap: Part D spending on covered drugs is capped at $2,100 for 2026. Once you hit it, you pay $0 for the rest of the year on covered drugs.
- Maximum deductible: Plans cannot set a Part D deductible higher than $615 in 2026 ($700 in 2027).
- Coverage gap: The old "donut hole" was eliminated in 2025. Part D now has three phases: deductible, initial coverage, and catastrophic.
- Medicare Prescription Payment Plan: You can ask your plan to spread your drug costs across monthly payments instead of paying at the pharmacy counter. It does not lower the total — it smooths the timing.
- IRMAA: Higher-income enrollees pay a Part D surcharge; the 2026 threshold begins above $109,000 for a single filer.
Local context for Riverton
Riverton sits in Salt Lake County, which is the county CMS uses to determine which Medicare Advantage and stand-alone Part D plans are available to you. If you are comparing plans, the plan finder at medicare.gov uses your ZIP code to pull the correct Salt Lake County lineup.
Utah's State Health Insurance Assistance Program (SHIP) offers free, one-on-one counseling — no sales involved — and can walk through your ANOC with you.
If a change affects a drug you take
You have options, and you have time — if you use it.
1. Talk to your prescriber. They may be able to switch you to a preferred alternative or submit prior authorization/step therapy paperwork. 2. Ask your plan for an exception. Plans have a formal process to request that a drug be covered at a lower tier or without a restriction. 3. Compare other plans during AEP. Between Oct. 15 and Dec. 7, you can switch to a different Part D or Medicare Advantage plan for a January 1 start. 4. Use MA Open Enrollment if needed. From Jan. 1 to March 31, Medicare Advantage members get one more chance to change MA plans or return to Original Medicare. 5. Ask about a transition fill. New plan members are generally entitled to a temporary one-time supply of a non-formulary drug early in the plan year, giving you time to switch drugs or file an exception.
