It arrives in a white envelope with your plan’s logo in the corner, sometime in the second half of September. Inside is a stack of paper using phrases like “cost-sharing tier” and “maximum out-of-pocket amount.” Most people give it ninety seconds and file it away.
That is a fair response to a document that looks like homework. It is also the most expensive ninety seconds in the Medicare year, because that paper is the only place your plan tells you, in writing, what it is doing differently in 2027.
The document is the Annual Notice of Change — the ANOC. Every Medicare Advantage plan and every standalone Part D plan must send it so it reaches you by September 30, two weeks before enrollment opens on October 15. You are meant to read it, and then decide.
So let’s read it together. Not another checklist — a walkthrough of the actual document, through the CMS-standardized sections 1.1 to 1.7 and then 2 to 5, in order.
- The ANOC must reach you by September 30 — federal rules require notice at least 15 days before enrollment opens.
- The ANOC and the Evidence of Coverage are different documents. The ANOC lists what changed, due September 30. The EOC is the full contract, due October 15.
- Read the 2027 column of the cover table on its own before comparing it to 2026. It is a far better test.
- Provider network and pharmacy network are separate sections, 1.3 and 1.4 — both say a change occurred without saying whether it hit you.
- Your medical out-of-pocket maximum and your drug spending are separate buckets. Still the most misread pair of numbers in the packet.
- The standard Part D deductible rises to $700 from $615, and the annual out-of-pocket threshold to $2,400 from $2,100.
- The Part D Premium Stabilization Demonstration ends after 2026. The $50 cap on drug plan premium increases does not exist for 2027.
- A plan leaving your county sends a non-renewal letter instead, due at least 90 days ahead, with enrollment rights the ANOC does not carry.

What is in the envelope?
The September mailing is not one document. The pieces have different jobs and different deadlines, and people often start with the wrong one.
| Document | What it is | Due to you | What to do with it |
|---|---|---|---|
| Annual Notice of Change | This year’s plan against next year’s. Only what changed. | September 30 | Read it. This is the one. |
| Evidence of Coverage | The full 2027 contract — “the legal, detailed description of our plan benefits.” | October 15 | Keep it for looking things up. |
| Provider Directory | Which doctors and hospitals are in network. | October 15 | Check your providers by name, then confirm by phone. |
| Pharmacy Directory | Which pharmacies are in network, and which are preferred. | October 15 | Check preferred versus standard, not just membership. |
| Drug List (formulary) | Covered drugs and the tier each one sits on. | October 15 | Look up every prescription by name, strength and form. |
| LIS Rider | Sent only if you get Extra Help. Your actual drug costs. | September 30 | Read it — the plan’s own published amounts do not apply. |
The ANOC is the short one, deliberately. CMS publishes a model ANOC every plan must follow, and its instructions say the standardized text “must be used in the same order as the standardized material.” That is why this walkthrough works for any carrier.
The cover page and the Summary of Important Costs
The first line names the plan you are in now: “You’re enrolled as a member of,” then your 2026 plan name. If the 2026 and 2027 names differ — a rename, a consolidation, a move into a renewal plan — everything downstream deserves fresh eyes.
The cover states the window, October 15 to December 7, and warns that doing nothing enrolls you automatically in the 2027 version. Doing nothing is a decision.
Then comes the table the packet is built around: “Summary of Important Costs for 2027,” with columns headed “2026 (this year)” and “2027 (next year).” The rows are fixed — plan premium, deductible, maximum out-of-pocket, primary care and specialist visits, inpatient stays, and Part D coverage split into the drug deductible, tier cost sharing, and the Catastrophic Coverage Stage.
Read it a particular way. Cover the 2026 column with your hand and read only 2027. Then ask: if this plan were new to me today, at these numbers, would I choose it? Side-by-side reading invites a weaker question — “how much did it go up?”
Section 1.1 — Changes to the Monthly Plan Premium
Up to three rows appear. The monthly plan premium, followed by a parenthetical every plan must print: “You must also continue to pay your Medicare Part B premium.” A Part B premium reduction row if your plan offers a giveback — one that shrinks is a premium increase in disguise. And any additional premium for optional supplemental benefits.
Below it sits a list headed “Factors that could change your Part D premium amount”: a lifetime late enrollment penalty after 63 days without creditable drug coverage, a higher income surcharge paid to the government rather than your plan, and Extra Help.
Why this line is different in 2027
Since 2025, CMS has run the Part D Premium Stabilization Demonstration. When the Inflation Reduction Act rebuilt Part D, standalone drug plans might have answered with steep increases or market exits. The demonstration absorbed part of that risk.
On July 28, 2026, CMS announced it is ending. Analysis of the 2027 bids “indicates that Part D plan sponsors had sufficient experience under the redesigned Part D benefit,” so CMS will “discontinue the demonstration at the end of CY 2026 to return the program to operating under traditional market conditions in CY 2027.”
| Plan year | Reduction to the base beneficiary premium | Cap on a plan’s year-over-year premium increase | Status |
|---|---|---|---|
| 2025 | $15 per month | $35 | First year |
| 2026 | $10 per month | $50 | Scaled back |
| 2027 | None | None | Discontinued |
That $50 cap is why a drug plan could not raise your premium further from 2025 to 2026, whatever its costs did. For 2027 it is gone, and KFF concluded that ending the subsidy could mean larger increases for some beneficiaries.
| Part D standard benefit figure | 2026 | 2027 | Change |
|---|---|---|---|
| Standard (maximum allowable) deductible | $615 | $700 | Up $85 |
| Annual out-of-pocket threshold | $2,100 | $2,400 | Up $300 |
| Base beneficiary premium | $38.99 | $41.33 | Up $2.34 — the 6% statutory maximum |
| Your cost sharing past the threshold | $0 | $0 | Unchanged |
| Premium Stabilization Demonstration | In effect | Ended | Discontinued after CY2026 |
The base beneficiary premium is a benchmark inside CMS payment formulas — not what you pay, and not in your ANOC. It matters because it landed exactly on the 6% statutory ceiling. CMS set the 2027 national average monthly bid at $296.05.
Section 1.2 — Changes to Your Maximum Out-of-Pocket Amount
This section opens with a line every carrier must print: “Medicare requires all health plans to limit how much you pay out of pocket for the year.” Then your 2026 and 2027 maximums, and the promise that once you reach it, covered Part A and Part B services cost you nothing more that year.
There may be two numbers rather than one. In a PPO you typically see an in-network maximum and a higher combined in-and-out-of-network maximum. Those are not alternatives — the combined figure is your true ceiling the moment you go out of network.
And it has nothing to do with your prescriptions. The document says so outright: “Our plan premium and your costs for prescription drugs don’t count toward your maximum out-of-pocket amount.” Part D runs on its own track, with its own $2,400 threshold in 2027.
A rising ceiling describes your worst year rather than your average one. A low premium with a high ceiling is a bet that you stay healthy — sound for some people, but it should be deliberate. Our guide to Medicare Advantage plans covers how the pieces fit.
Sections 1.3 and 1.4 — the provider and pharmacy networks
Both follow the same pattern: a paragraph saying whether anything changed, then a pointer to the 2027 directory. Neither names the practice, hospital system, or pharmacy chain that left — the most consequential material in the packet, and the least specific text in it.
So these are not sections you read. They are sections you act on, in about twenty minutes:
- List every provider you use — primary care physician, every specialist, your hospital, and any outpatient or imaging facility from the last two years.
- Check each against the 2027 directory, not the 2026 one. Plan websites often default to the current year. Find the year selector first.
- Call each office and ask: “Are you contracted with this specific plan for 2027?” Not “do you take Medicare” — a different question with a different answer.
- Do the same for your pharmacy, then ask the second question Section 1.4 exists to raise.
That second question is preferred versus standard. Section 1.4 notes the network “includes pharmacies with preferred cost sharing, which may offer you lower cost sharing than the standard cost sharing offered by other network pharmacies for some drugs.” Both are in network. Both can charge very different amounts for the same pill.
Houston makes both sections unusually consequential. Harris County holds a dense concentration of large systems — Memorial Hermann, Houston Methodist, HCA Houston Healthcare, Kelsey-Seybold, St. Luke’s Health — each renegotiating with each carrier on its own timeline. A system can be in one plan from a carrier and out of another. “My doctor takes that insurance company” is not the same statement as “my doctor is in this plan.”
Section 1.5 — Changes to Benefits & Costs for Medical Services
Usually the longest section and the most skimmed. It is also where the supplemental benefits live — what most people chose their plan for.
Know this first: CMS instructs plans to list only what changed — benefits added or dropped, new limitations including referrals and prior authorization, and every change in cost sharing. If a service is not in the table, its cost is unchanged. Everything printed here is, by definition, a change.
Take two passes. First, the services you actually used — $10 more on something you use twice a year is noise; the same $10 monthly is not. Second, the extras.
| Benefit | What changes quietly | The question to ask |
|---|---|---|
| Dental | The split between preventive and comprehensive work, and the annual maximum. | What is the 2027 maximum, and does it cover cleanings, major work, or both? |
| Vision | The eyewear allowance and how often it renews. Exams and hardware are separate. | What is the allowance, and how often does it renew? |
| Hearing | Aids covered, copay per aid, and whether a supplier network applies. | What is the 2027 copay per aid, and through whom? |
| Over-the-counter | Quarterly or annual, whether it rolls over, and which retailers accept the card. | How much per quarter, and can I use it where I shop? |
| Transportation | Trips per year and the mileage limit. Houston distances make it matter. | Does the limit reach the Texas Medical Center from my address? |
| Optional supplemental packages | These carry their own premium, listed in Section 1.1. | Am I still paying for an add-on, and did it change? |
A reduced extra benefit is not automatically a reason to change plans. If the dental maximum dropped $250 but your doctors are still in network and your medications sit at the same tier, that may be a fair trade. Reading closely is about knowing what you are keeping.
Section 1.6 — Changes to Part D Drug Coverage
Sections 1.6 and 1.7 answer two questions: is my drug still covered, and what will it cost. Section 1.6 is the Drug List. Its standardized language says the plan “made changes to our Drug List, which could include removing or adding drugs, changing the restrictions that apply to our coverage for certain drugs, or moving them to a different cost-sharing tier” — without saying whether yours was affected.
| What happened | What it means | How much it matters |
|---|---|---|
| Removed from the Drug List | The plan no longer covers it next year. | Highest. You need an alternative, an exception, or a different plan. |
| Moved to a higher tier | Still covered, but your share goes up. | High. A jump to a brand or specialty tier can multiply your cost. |
| Prior authorization added | Covered, but your prescriber must get approval first. | Moderate. Manageable, but start in December, not January. |
| Step therapy added | The plan wants you to try a preferred alternative first. | Moderate. If you already failed it, your prescriber can document that. |
| Quantity limit added | Covered, but only a set amount per fill or period. | Varies. Check it against your actual dosing. |
Do this with your bottles in front of you, searching by exact name, strength and form — 20 mg and 40 mg tablets can sit on different tiers, and brand and generic are separate entries. For five prescriptions it is a fifteen-minute job.
The ANOC also names your options if a change hits a drug you take: a temporary supply, a formulary exception, or a different drug worked out with your prescriber. All three go better started in December than discovered at the counter in January.
Section 1.7 — Changes to Prescription Drug Benefits & Costs
Section 1.7 opens by asking whether you get Extra Help. If you do, the published drug costs largely do not apply — yours are in the LIS Rider. Everyone else moves to the three payment stages.
| Stage | What happens | 2026 | 2027 |
|---|---|---|---|
| Stage 1 — Yearly Deductible | You pay full cost until you reach the deductible. Many plans set theirs lower, and some have none — the ANOC then says the stage does not apply. | Up to $615 | Up to $700 |
| Stage 2 — Initial Coverage | You pay a copay or coinsurance that varies by tier, until your out-of-pocket spending reaches the annual threshold. | Until $2,100 | Until $2,400 |
| Stage 3 — Catastrophic Coverage | In the plan’s own words, “you pay nothing for your covered Part D drugs,” generally for the rest of the calendar year. | $0 | $0 |
The story there is mixed. You spend $300 more before reaching the ceiling, and $85 more before coverage begins if your plan charges the full deductible. But before 2025 Part D had no annual out-of-pocket limit at all — the $2,400 threshold, past which covered drugs cost nothing, remains its most valuable feature.
Sections 2 through 5 — the part everyone skips
Section 2, Administrative Changes, appears only if there are any — how you pay your premium, or the plan’s contract number. If your premium is auto-drafted or deducted from Social Security, read it.
Section 3, How to Change Plans, is the operational heart. To stay, do nothing. To leave: enroll in another Medicare health plan or a standalone Part D plan, either of which disenrolls you automatically, or send a written request to return to Original Medicare without drug coverage. Section 3.1 gives the December 7 deadline and the single switch Advantage members get between January 1 and March 31, 2027.
Section 4, Get Help Paying for Prescription Drugs, is the section most likely to be worth real money and the most reliably skipped. It describes Extra Help, which the document says can cover “up to 75% or more of your drug costs including monthly drug plan premiums, yearly deductibles, and coinsurance.”
Section 4 also covers the Medicare Prescription Payment Plan, which spreads your out-of-pocket drug costs across the remaining months in level payments. CMS requires blunt wording: “This payment option might help you manage your expenses, but it doesn’t save you money or lower your drug costs.” Enrollment renews automatically if you stay in the same plan.
Section 5, Questions?, is contact information plus a pointer back to the Evidence of Coverage — “the legal, detailed description of our plan benefits.” The ANOC says what moved; the EOC governs.
What the ANOC does not tell you
It does not compare your plan to any other plan. The ANOC compares across time, never across the market. A premium that rose $8 might still be the strongest fit available to you, or the weakest. Nor does it carry your star rating, published separately each fall.
It does not arrive at all if the plan is leaving. If your plan is not renewing in your county for 2027, you get a non-renewal notice instead — required by mail at least 90 calendar days ahead, so the first days of October. That letter carries a special enrollment period with more time and more options than the standard window. Act on it rather than filing it.
It does not tell you whether another path is open to you. Moving from Medicare Advantage to Original Medicare with a supplement is a question about Texas underwriting and your health history, and Texas has no birthday rule letting you switch supplements without health questions. Our pages on plan types and Medicare eligibility show where the paths diverge.
The one-page worksheet
Everything above condenses onto one sheet. Transcribe rather than skim — writing a number down is what makes you notice it.
- From the cover table: the 2027 premium, deductible, maximum out-of-pocket, primary care and specialist copays, and inpatient cost sharing.
- From Sections 1.1 and 1.2: any Part B giveback or add-on premium, and both out-of-pocket maximums if you are in a PPO.
- From Sections 1.3 and 1.4: every doctor, hospital and pharmacy you use, with a date beside each one confirmed for 2027 by phone.
- From Sections 1.5 to 1.7: any supplemental benefit that shrank, each medication and what happened to it, and your 2027 drug deductible.
- One line at the bottom: the change that bothers you most. If you cannot name one, that is a real and reassuring finding.
Why this lands hard in Harris County
Most of what changes year to year — networks, copays, supplemental benefits — belongs to Medicare Advantage plans, which in Harris County makes the ANOC nearly universal. Per the CMS Medicare Advantage State/County Penetration file for August 2026, the county had 664,734 Medicare eligibles, of whom 409,243 were in an Advantage plan — 61.56%.
The mail also hits everyone at once. Several hundred thousand envelopes land in Harris County mailboxes in the last week of September, and by mid-October every licensed agent in the county is booked. The calmest Decembers belong to people who read the document early and asked their questions before the rush. Our north Houston office and south Houston office fill their October calendars from late September onward.
