A zero-dollar plan premium is easy to understand. The bill that follows it is less simple. A prescription can sit on a different cost tier, a pharmacy can have different terms, and a doctor’s name can belong to one network but not another. Medicare’s autumn comparison is therefore about a year of coverage, even when the advertisement gives the monthly premium the biggest type.
The question is especially timely this October. In its September 28, 2026 announcement, the Centers for Medicare & Medicaid Services projected a lower national average Medicare Advantage premium for 2027. It projected a small increase in the average stand-alone Part D premium. Neither figure quotes the cost of the exact combination of medicines, clinicians and services a reader will need.
The useful task is to move from that broad outlook to a verifiable comparison: the exact 2027 plan, the same assumptions about care, and a separate record of anything still unresolved. A lower estimated total cannot settle an unanswered coverage question. A complete-looking spreadsheet can be wrong simply because it has put zero in a cell that should say unknown.
This guide follows those distinctions through the enrollment dates, plan documents and a deliberately fictional cost example. It does not collect a medication list or inspect an account. The examples explain how to read a comparison; Medicare Plan Finder, current plan materials and individualized counseling are the places to investigate real options.
The national premium falls. The local story can go the other way.
CMS’s projected weighted average monthly Medicare Advantage premium falls from $14.37 in 2026 to $12 in 2027. Its projected average total monthly premium for stand-alone Part D plans rises from $35.09 to $36. For Advantage plans that include drug coverage, the average monthly Part D total premium after rebates falls from $11.32 to $7. These describe different groupings or components, not three charges to add together.
The state fact sheets make the limitation concrete. Virginia’s average Advantage plan premium falls from $8.80 to $6.67, while West Virginia’s rises from $13.21 to $15.36. Both report that all Medicare beneficiaries in the state have access to an Advantage option with a $0 monthly plan premium. A minimum available premium and an average answer different questions. CMS’s Virginia and West Virginia fact sheets supply these neighboring-state examples; they are not a representative sample of the country.
Even a state average is still too broad for a household decision. Plans can serve particular counties, and the insurer can offer multiple products with different costs and benefits. The brand on a familiar envelope is not enough to identify the plan. Keep its exact name, identifying number, coverage year and service area with every comparison you save. Medicare’s explanation of local plan availability is the reason for that extra precision.
01 / THE HEADLINE IS NOT A QUOTE
Different premium measures, different directions
Each pair links 2026 to the projected 2027 monthly premium. All five rows use the same $0–$40 scale. National rows describe different groupings or components; never add them.
Virginia and West Virginia both report access to a $0-premium Advantage plan for 100% of Medicare beneficiaries. That minimum does not determine the average, local choice or total cost.

Comparing, enrolling and using coverage happen at different times
The 2027 Medicare & You calendar identifies October 1, 2026 as the point to begin comparing next year’s coverage. Annual Open Enrollment runs October 15 through December 7. A permitted change takes effect January 1, 2027, provided the plan receives the enrollment request by December 7. Comparison access in early October is not the same as an enrollment window.
What can change depends on existing coverage. The annual window permits changes involving Medicare Advantage and drug coverage, including switching between Original Medicare and Advantage. Someone returning to Original Medicare may need a separate drug plan and may want Medigap. Those are additional pieces to investigate, rather than assumptions supplied by the calendar. Medicare’s Open Enrollment page sets out the permitted moves and receipt deadline.
People keeping their current Medicare coverage generally do not need to re-enroll. That does not mean next year’s terms are unchanged. Conversely, a notice that a plan is ending should not be treated as a routine renewal. Keep that notice and ask Medicare or a State Health Insurance Assistance Program, known as SHIP, which rights and deadlines apply. An ordinary annual-enrollment guide cannot settle every special situation.
The first document should be the one describing what changed
Your plan’s Annual Notice of Change, or ANOC, describes changes in coverage, costs and other terms that begin in January. Medicare says to expect it in September and contact the plan if it is missing. Start there before assuming an advertisement’s description also describes your current plan’s renewal. Medicare’s ANOC guidance gives the notice this specific job.
The Evidence of Coverage, or EOC, does a different job: it explains what the plan covers, how much you pay and other detailed terms. A formulary supplies the drug list and associated rules; a provider directory helps locate participating clinicians and facilities. The documents work together. One reassuring premium line cannot substitute for all of them. Medicare’s EOC guidance recommends reviewing it each year.
For each change that matters, write down the question beside the document and page that raised it. “Does this specialist participate in this exact 2027 plan at this location?” is more useful than “Is my doctor covered?” If two sources disagree, keep both dated versions and request an explanation from the plan. Do not quietly choose the answer that makes the comparison look better.
The year is part of the evidence. A search result can open an older EOC, and a saved directory can describe a different plan sold by the same insurer. Before resolving a discrepancy, check whether the documents actually refer to the same product and year. If they do, record the conflicting passages and ask which current terms apply. A newer-looking screen alone is not a written explanation of the difference.
02 / WHICH DOCUMENT CAN ANSWER THAT?
Follow the question to its evidence
- Annual Notice of Change
- What changes in January?
- Evidence of Coverage
- What are the detailed coverage and cost terms?
- Formulary + pharmacy terms
- Which drug, restrictions, pharmacy and cost sharing?
- Directory + plan/provider confirmation
- Which exact plan, location and service?
- Enrollment + Medigap rights
- Can the full replacement package begin when needed?
No document is highlighted yet. Identify the exact plan, year and unresolved question.

The premium is one line in the annual arithmetic
Medicare’s Plan Finder can compare local health and drug plans using the prescriptions and pharmacies entered there. Use consistent assumptions across candidates. A total based on a different drug supply or pharmacy is answering a different question, even if both totals are labeled annual. This page deliberately uses fictional options instead of requesting private health details.
Consider Option A with a $0 monthly plan premium and $900 in estimated annual drug spending. Option B has a $20 monthly plan premium and $500 in annual drug spending. Looking only at these two components, A is $900 and B is $740: twelve payments of $20, plus $500. The option with a premium is $160 lower on this limited comparison.
Now introduce medical spending. In an illustrative middle scenario, add $300 to A and $700 to B. The included annual costs become $1,200 and $1,440. A is now $240 lower. The premium did not change, nor did the drug assumptions. The result changed because the earlier comparison omitted a component that affects the options differently.
These are invented numbers, not actual plans or predicted medical bills. The display excludes Part B premiums, surcharges, noncovered services and other possible expenses. It does not simulate benefit limits, deductibles, networks or how real cost sharing changes with care. Its purpose is narrower: to show which assumption moved the result, and to keep an unknown medical estimate from masquerading as zero.
03 / FICTIONAL OPTIONS, VISIBLE ASSUMPTIONS
Watch one omitted component change the comparison
Two invented options. Annual included cost = 12 × monthly plan premium + annual drug estimate + assumed medical spending. No real plan or personal health information is used.
| Component | Option A | Option B |
|---|---|---|
| Monthly plan premium | $0 | $20 |
| Annual plan premium | $0 | $240 |
| Annual drug estimate | $900 | $500 |
| Assumed medical spending | Unknown | Unknown |
| Included annual total | Incomplete | Incomplete |
Known premium + drug subtotal: $900. Medical spending is unknown.
Known premium + drug subtotal: $740. Medical spending is unknown.
Medical spending is unknown. The visible bars show only known fictional subtotals, not annual totals.
Clayso’s invented teaching example. Both bars use a common $0–$2,400 scale. Excludes Part B, surcharges, noncovered services and other expenses; no deductible, benefit limit or real plan rules are simulated. Medicare’s cost guidance explains why those omitted terms matter.
In a real comparison, read the label before adding anything. If a displayed total already includes premiums and estimated drug costs, adding twelve premiums again counts the same money twice. A deductible may already be reflected in an estimate. Preserve the source’s description beside the number, and ask about any unclear component rather than combining figures whose boundaries you do not know.
An annual estimate is also different from a bad-year limit or the cash needed in a particular month. Medicare Advantage plans have limits on certain out-of-pocket costs, and their exact terms need checking. A simple straight line cannot reproduce those rules. A low-use scenario, a higher-use scenario and the plan’s actual limits should remain distinct pieces of a real review. Medicare’s health-plan cost guidance explains the additional factors.
Keep the unit of each figure visible too. A monthly premium becomes an annual premium after multiplication by twelve; an annual drug estimate should not be multiplied again. A copayment for one visit is neither a monthly bill nor a full-year total until an explicit use assumption is attached. This bookkeeping is modest, but it prevents a precise calculation from hiding a mismatch in the numbers being compared.
04 / WHY THE LINES CROSS
The cheaper fictional option depends on the assumption
The horizontal axis is an invented medical-spending multiplier, not visits or predicted care. A adds $300 per unit; B adds $700. The lines are arithmetic illustrations, not real benefit curves.
Fictional medical-spending multiplier
No scenario is selected. The fixed lines show the invented relationship; no selected point or annual total has been applied.
Read all fictional values without using the chart
| Multiplier | Medical A / B | Total A / B |
|---|---|---|
| 0 | $0 / $0 | $900 / $740 |
| 0.4 | $120 / $280 | $1,020 / $1,020 |
| 1 | $300 / $700 | $1,200 / $1,440 |
| 2 | $600 / $1,400 | $1,500 / $2,140 |
Clayso arithmetic only. A real plan can have deductibles, limits and nonlinear cost sharing. This graph is neither a coverage model nor an estimate of a reader’s care.
The crossing point in the fictional graph is an arithmetic result, not a predicted level of care. It says that these invented component assumptions produce equal included costs at that point. It does not say a reader will need that amount of care, or that a plan’s actual payment rules are linear. If a real estimate changes, identify the changed assumption before treating the new total as evidence that one plan became better.
The drug-cost cap does not cap the whole health budget
For 2027, the Medicare handbook states that a Part D drug deductible cannot exceed $700 and out-of-pocket costs for covered Part D drugs are capped at $2,400. Once the applicable limit is reached, covered Part D drugs cost $0 for the rest of the year. That is a specific protection within drug coverage, not a ceiling on premiums, every medicine purchase or all medical care. The handbook’s drug-cost section separates the deductible, premium and limit.
The Medicare Prescription Payment Plan answers another question: when covered drug costs are paid. It can spread those out-of-pocket costs across the calendar year, but it does not lower the total. A household could benefit from easier timing while still needing to compare plans and ask about assistance. Keep the payment option separate from Extra Help, which can reduce costs for people who qualify.
A drug name on a list is the start of the access check
Each drug plan has its own formulary. Check the exact medication, strength and form, then look for its tier and any restrictions. Prior authorization, quantity limits and step therapy are different requirements. A price beside the drug does not establish that every requirement has already been met. Medicare’s formulary explanation and the current plan materials supply the next questions.
The pharmacy matters separately. Preferred in-network pharmacies may offer lower cost sharing than other network pharmacies; going outside the network can mean paying the full cost. Compare a pharmacy you can realistically use, including refill arrangements. A lower estimated price at an inaccessible location is not the same practical option. Medicare’s pharmacy guidance explains these distinctions.
A temporary refill can leave the larger problem unresolved. The 2027 handbook says that within the first 90 days of new drug coverage, a member may get a one-time 30-day transition supply of an existing drug that is normally excluded or subject to prior authorization or step therapy. Ask what must happen before it runs out. That transition-fill provision is not a promise of ongoing coverage. Keep treatment changes and alternatives with the prescriber.
Verify the provider, the location and the service
For an Advantage comparison, keep a short list of the clinicians, hospitals and services that matter to you. Plans may use networks; some offer nonemergency care outside them at a higher cost. Certain services can require approval or a referral. Those distinctions matter even when a familiar doctor appears in a directory. Medicare’s Advantage overview describes the network and authorization boundaries.
Ask the plan and provider about the exact product, coverage year and practice location. If a hospital procedure is relevant, ask about the facility and the needed service rather than treating one clinician’s participation as a complete answer. Record what is confirmed and what remains open. A missing answer belongs in the access column, where it remains visible alongside the cost estimate.
This is why the interactive never declares a real plan the winner. You can rehearse the arithmetic while still having an unresolved access question. Choosing “checked” below records only your own description of the review; it does not authenticate a document or verify a network. If information conflicts, the useful output is a question for the plan, not a more confident score.
05 / PRICE AND ACCESS STAY SEPARATE
A lower number cannot close an open coverage question
The numbers above are always a teaching example.
Verify drugs, pharmacies, providers, service conditions and effective dates with current sources.
The article has verified no real coverage. An unknown answer stays open.
A documented network answer is useful, but it does not promise that every future service will be covered without conditions. Keep the separate authorization, referral and cost-sharing questions attached to the relevant service. If there is ongoing treatment or a time-sensitive refill, raise the continuity question with the plan and clinician before assuming a January switch will work smoothly. A benefits comparison should not become a reason to interrupt care.
The autumn deadline does not guarantee Medigap
Moving from Medicare Advantage to Original Medicare and buying a Medigap policy are separate decisions. Federal Medigap protections include a six-month open enrollment period beginning when someone is 65 or older and enrolled in Part B. Other guaranteed-issue rights depend on circumstances, and state law can add protections. The federal Medigap buying guide explicitly says to check state opportunities too.
Before changing coverage, establish whether the desired policy is available, whether medical underwriting applies, its premium and its effective date. Consider separate drug coverage as part of that replacement package. If employer, union or retiree coverage is involved, speak to the benefits administrator before making changes: Medicare warns that joining other coverage can affect coverage for you or dependents, and it may not be recoverable.
The January 1–March 31 Medicare Advantage Open Enrollment Period is narrower than the autumn window. It lets people already in Advantage make one change to another Advantage plan or return to Original Medicare and join a separate drug plan. It does not generally let someone in Original Medicare use that window to join Advantage or switch stand-alone drug plans. The change takes effect the first of the month after the plan gets the request. The handbook’s enrollment table is the relevant reference, with special enrollment situations checked separately.
Get the unresolved questions into the right hands
Extra Help assists qualifying people with Part D costs; some receive it automatically and others apply. Medicare Savings Programs are administered through states and may help with premiums and other cost sharing. Do not infer eligibility from a national threshold or from this article. State rules and individual circumstances matter. Medicare’s Extra Help and Savings Program guidance identify the official routes.
Extra Help is not available in the U.S. territories listed by Medicare, including Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa; other local assistance may be available. Readers there should ask the appropriate Medicaid office about programs. That geographic boundary is another reason a general national guide should not decide an individual assistance result.
For free, personalized insurance counseling, contact SHIP through Medicare’s official help page. Medicare can also be reached at 1-800-633-4227, with TTY at 1-877-486-2048. Bring the exact plan identifiers, dated documents and unresolved questions. Keep your Medicare number, medication list and private records out of public comments and this interactive.
After an authorized enrollment, retain the confirmation and stated effective date, then reconcile later notices with them. If keeping the current plan, save the reviewed renewal documents and any answers that affected that decision. The goal is a traceable coverage decision for January: what you expect to pay, what access you checked, what can change and whom to contact when the paperwork disagrees.
If you are helping someone else, the same structure works without putting their private details into an open webpage. Review the documents together, keep the sensitive list in their own secure records, and bring questions to the appropriate official service. This page’s final note records only broad review topics and the fictional arithmetic you chose. It cannot replace the person’s own enrollment decision or confirmation from the receiving plan.
