Medicare Part D
Why a covered drug can change on Jan. 1: how Post Falls readers should read this fall's ANOC
POST FALLS, Idaho — The envelope usually shows up in late September. It is thin, easy to mistake for junk mail, and it can quietly rewrite what you pay at the pharmacy counter on January 1. It is called the Annual Notice of Change, or ANOC, and every Medicare Advantage and stand-alone Part D plan is required to send one before the Annual Enrollment Period opens on Oct. 15.

- Your ANOC arrives by late September and spells out formulary, tier and utilization management changes that take effect Jan. 1, 2027.
- A drug can stay "covered" but move tiers, require prior authorization, add a quantity limit, or fall under step therapy — each affects what you pay or how you get it filled.
- The Annual Enrollment Period runs Oct. 15 through Dec. 7, which is your main window to switch plans if the changes do not work for you.
- The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027, and the optional Medicare Prescription Payment Plan lets you spread that spending across the year.
This fall, the ANOC matters as much as ever. The Part D out-of-pocket cap rises from $2,100 in 2026 to $2,400 in 2027, the Part D maximum deductible is $700 in 2027 (up from $615 in 2026), and plans are once again adjusting their drug lists — called formularies — around those rules. A medication you filled without a second thought in 2026 could sit on a different tier, need prior authorization, or come with a quantity limit in 2027. The drug is still "covered." The path to getting it may just look different.
What the ANOC actually is
The Annual Notice of Change is a side-by-side comparison of your plan in 2026 and the same plan in 2027. It covers the premium, the deductible, the drug list, the pharmacy network, and — for Medicare Advantage — the medical benefits and provider network too.
Post Falls is in Kootenai County, where residents can compare their current plan's ANOC against every other Medicare Advantage and Part D plan offered in the county during the Annual Enrollment Period. The ANOC is not a sales document. It is a required disclosure, and the drug section is where most surprises live.
Tiers: same drug, different shelf
Part D plans sort covered drugs into tiers, usually five or six of them. Lower tiers (generics, preferred generics) generally cost less at the counter; higher tiers (non-preferred brands, specialty) generally cost more. Plans are allowed to move a drug from one tier to another between plan years.
That is why a prescription you have taken for years can suddenly cost more in January even though the plan still "covers" it. The ANOC will show the tier in 2026 and the tier in 2027. If a drug you take has moved up, that is your cue to price it out under other plans before Dec. 7.
Prior authorization, quantity limits and step therapy
These three tools are called utilization management, and plans can add, remove, or change them each year.
- Prior authorization (PA) means your prescriber has to get the plan's approval before the pharmacy can fill the drug. It is common for higher-cost or higher-risk medications.
- Quantity limits (QL) cap how much of a drug the plan will cover in a set period — for example, a certain number of tablets per 30 days.
- Step therapy (ST) requires you to try a lower-cost alternative first, and only move to the requested drug if the first one does not work or is not tolerated.
None of these means "denied." They mean extra paperwork, usually handled between your prescriber and the plan. The important thing is to know they are coming before you show up at the pharmacy in January.
How to actually read the ANOC
Set aside twenty minutes and a highlighter. Then:
1. Find the drug list section. It usually appears after premium and medical benefit changes. 2. Match each of your prescriptions to the new tier. Note anything that moved up. 3. Look for the letters PA, QL, or ST next to any of your drugs. Those are the utilization management flags. 4. Check whether your pharmacy is still "preferred." Preferred and standard pharmacies can charge different amounts under the same plan. 5. Note the deductible and the plan's approach to the out-of-pocket cap. The Part D cap is $2,100 in 2026 and $2,400 in 2027; once you hit it in true out-of-pocket spending on covered drugs, you pay nothing more for covered Part D drugs for the rest of that year.
If any of that gives you pause, use the Plan Finder at medicare.gov to compare, or call 1-800-MEDICARE. Idaho residents can also reach the state's SHIP program — Senior Health Insurance Benefits Advisors (SHIBA) — for free, unbiased counseling.
If a drug you take is changing
You have options, and none of them require panic.
- Switch plans during AEP (Oct. 15 – Dec. 7). This is the main window. Coverage from a new choice takes effect Jan. 1.
- Ask your prescriber about alternatives. Sometimes a therapeutically equivalent drug sits on a lower tier or has no restrictions.
- Request an exception. If your prescriber believes you need the specific drug at a lower cost-sharing level, they can file a formulary or tier exception with the plan.
- Use your transition fill. In most cases, if you are already taking a drug that the 2027 plan year has changed or dropped, Part D rules require the plan to provide at least a one-time transition supply (typically a 30-day fill) early in the year so you have time to work out a permanent solution.
- Consider the Medicare Prescription Payment Plan. This optional program, available in every Part D plan, lets you spread your out-of-pocket drug costs into monthly payments rather than paying large amounts at the pharmacy at once. It does not lower the total; it smooths the timing.
Remember that IRMAA — the income-related surcharge that can raise Part B and Part D premiums — begins above $109,000 for a single filer in 2026. If your income has dropped because of a life event, you can ask Social Security to reconsider.
