Choosing your first Medicare Advantage plan feels like a research problem and is really a filtering problem. There were 3,373 plans available nationally in 2026, 346 fewer than the year before, and the average beneficiary could choose from 32 of them with drug coverage. For 2027 our own county count, further down, finds a typical county offering 24 plans open to anyone, 19 of them with drug coverage. Nobody compares two dozen plans feature by feature. What works is eliminating most of them quickly on two criteria, and only then looking at the things the advertising talks about.

This guide is the order to do it in, and the three facts a first-timer needs before starting.

First, Three Things Nobody Tells You Clearly

You pay the Part B premium either way

A plan advertised at zero dollars a month does not mean you pay nothing. You still owe the standard Part B premium, $202.90 a month in 2026, whichever route you take, and it is usually deducted from your Social Security payment before you see it. The zero refers only to the plan’s own supplemental premium. That said, the zero is real and it is common: 67% of Medicare Advantage plans with drug coverage charge no premium beyond Part B, so a zero premium does not distinguish one plan from another. Almost everything else does.

No plan is endorsed by Medicare, whatever the ad implies

Federal marketing rules forbid a plan from claiming it is recommended or endorsed by CMS, Medicare, the Secretary or HHS. If a mailer or a television ad leaves you with the impression that the government is pointing you toward a particular plan, that impression is the product, not the fact. The only official comparison tool is Medicare’s own Plan Finder, and it ranks nothing.

Your first choice is not permanent

People freeze at this decision because they think they are locked in for life. They are not. If you join a Medicare Advantage plan when you first become eligible, you get a personal three-month window from the day your coverage starts in which you can change your mind. After that there is the Medicare Advantage Open Enrollment Period every January to March, and the Annual Enrollment Period each fall. Our guide to the Medicare enrollment periods sets out all of them.

One caveat worth carrying with you: the decision that is genuinely hard to reverse is not which Medicare Advantage plan you pick, but whether you go Medicare Advantage or Medigap in the first place. That one has a six-month window attached to it, set by federal law, and once it closes most states let insurers ask about your health, and we cover it in Medicare Advantage versus Medicare Supplement.

The Order to Check Things In

Most first-timers start with the premium, which is close to the least informative number available. Here is a more useful sequence, and the first two steps usually cut 32 plans down to a handful.

One: your own doctors. Medicare Advantage plans have networks, which Original Medicare does not. Check each of your doctors and any specialist you see regularly against the specific plan’s directory, not against the carrier’s name. A large insurer can have a dozen plans in one county, and your cardiologist may be in the network of only one of them. Whether that restriction is tight or loose depends on the plan type: HMOs are 57% of plans in 2026 and local PPOs 42%, a share that has grown steadily over the past decade, and the difference between the two is mostly what happens when you go out of network. Our HMO versus PPO comparison goes through it.

Two: your own prescriptions. Enter every medication you take, by name and dose, into the Plan Finder. A drug that is not on a plan’s formulary is not partly covered, it is not covered, and a drug on a high tier can cost more in a year than the premium difference between every plan on your shortlist.

Three: the out-of-pocket maximum. This is the number that decides what a bad year costs, and it varies enormously. The law lets a plan set its in-network limit as high as $9,250 in 2026, while the average plan sets it at $5,421. Two plans that look identical on premium can be $4,000 apart on the only figure that matters if you get seriously ill. Look up the plan’s own limit; never assume it is near the average.

Four: the star rating of that plan. CMS rates each contract on up to 43 quality measures. For 2027 the enrollment-weighted average is 3.99 stars and about 71% of enrollees are in contracts rated four stars or better, so four stars is ordinary rather than exceptional. Ratings also move a lot from one year to the next, so read the 2027 figure rather than relying on what a plan or an insurer scored before. Check the rating for the specific contract, not the carrier as a whole. We explain what the score is actually made of in star ratings explained.

Five, and only now: the premium and the extras. Dental, vision, hearing, a gym membership, an over-the-counter card. These are real and they are worth having, but they are worth a few hundred dollars and the three steps above are worth thousands. Use them to choose between finalists, not to pick finalists.

Choose for the Bad Year, Not the Good One

The single most common way a first Medicare decision goes wrong is that it is made by someone who is currently well, for someone who is currently well.

In an uneventful year — a few checkups, a couple of generic prescriptions — almost any plan looks fine, and the cheapest one looks best. The plans separate in the year with a hospital admission, a course of chemotherapy or a serious fall. In that year the premium is a rounding error and the out-of-pocket maximum is the whole story. Before you enroll, work out what that plan would cost you in the worst twelve months you can imagine, and ask whether you could pay it. That is the comparison the advertising never makes.

What You Will Actually Be Choosing From in 2027: Our County Count

National averages hide the thing a first-timer most needs to know, which is what the menu looks like in one county. So we counted it. We took the CMS Landscape file for 2027, which lists every Medicare Advantage plan sold in every county for the coming year, and the same file for 2026. We kept only plans anyone can join, leaving out special needs plans, and counted each plan option separately, which is why our totals run a little above KFF’s. Each figure below is the middle value across roughly 3,000 counties.

In the typical county	2026	2027
Plans open to anyone on sale	26	24
…of which include drug coverage	20	19
Insurers selling them	5	5
Lowest out-of-pocket limit on offer	$3,400	$4,000
Highest out-of-pocket limit on offer	$9,250	$9,850
Gap between the two	$5,550	$5,450
Gap among the $0-premium plans alone	$5,250	$5,350

The last row is the one to remember. In the typical county, the plans that charge nothing beyond Part B are $5,350 apart on the limit that decides a bad year, and in 85.6% of counties that gap is $3,000 or more. Filtering your shortlist to “$0 premium” removes almost nothing that matters. It is also why the step order above puts the out-of-pocket maximum third and the premium last: the earlier line about two plans being “$4,000 apart” turns out, county by county, to be on the cautious side.

The floor has moved up. The most protective plan in a typical county had a limit of $3,400 in 2026; for 2027 it is $4,000. Across all plans open to anyone, the middle limit rose from $5,900 to $6,600, which we break down in Medicare Advantage plan costs explained. If you read an average from 2026 elsewhere, including the KFF figures quoted above, assume the 2027 plan in front of you is a little less generous until you have checked its own number.

Choice is thinner in some places. For 2027, 307 counties have five plans open to anyone or fewer, up from 205, and 424 counties have forty or more, down from 563. In a thin county the doctors-and-drugs filter can leave one plan or none. That is a reason to look seriously at Original Medicare with a Medigap policy while your six-month window is open, not a reason to take whatever is left.

A sensible combination usually exists. We matched each plan to its contract’s 2027 star rating. In 81.8% of counties there is at least one plan open to anyone that charges no premium beyond Part B, is rated four stars or more, and has an out-of-pocket limit at or below the national middle value of $6,600. Whether that plan covers your doctors and your prescriptions is the part only you can check, and our step-by-step Plan Finder guide shows exactly where to look.

How we counted: plans of type HMO, HMO-POS, PPO, PFFS and MSA open to individual enrollment, special needs plans excluded, each county’s plans counted once. The method and the downloadable data are on our methodology page.

A Checklist You Can Work Through in an Afternoon

1. Write down every doctor you want to keep and every medication you take, with doses.
2. Open the Medicare Plan Finder and enter your ZIP code and that medication list.
3. Remove every plan that does not cover your drugs at a price you can live with.
4. Of what is left, remove every plan your doctors are not in. Check the plan’s own directory, and call the doctor’s office if the directory is ambiguous.
5. Compare the survivors on their out-of-pocket maximum first and their star rating second.
6. Break the tie on premium and extras.
7. If you are unsure, call your State Health Insurance Assistance Program. It is free, it is not selling anything, and this is exactly what it is for.

If you would rather read about the major carriers before you start, our insurer reviews go through each one’s costs, networks and weak points. Treat them as background, though. No carrier is good or bad everywhere; plans are built county by county, and yours is what matters.

Frequently Asked Questions

Which is the best Medicare Advantage plan? The question has no national answer, because plans are sold county by county and the average beneficiary is choosing among 32 of them with different networks, formularies and cost caps. We explain why in Best Medicare Advantage Plan 2027: Why There Isn’t One, where we tested it in every county.

What is the most common first-timer mistake? Choosing on the premium. Two thirds of plans with drug coverage charge nothing beyond Part B, so the premium rarely separates them, while their out-of-pocket limits can differ by thousands.

Do I pay anything on a zero-premium plan? Yes. The Part B premium of $202.90 a month is unavoidable, and you still pay copays and coinsurance when you use care, up to your plan’s limit.

What if I choose wrong? As a new Medicare Advantage enrollee you have a personal three-month window from the start of your coverage to switch, and after that the ordinary enrollment periods each year.

Should I take the plan my neighbor recommends? Only as a name to look up. Their plan may not be sold in your county, and even if it is, their doctors and prescriptions are not yours.

Bottom Line

Your first Medicare Advantage decision is not about finding the best plan. It is about eliminating, in the right order, the plans that do not cover your doctors or your medicines, and then choosing among what survives on the number that governs a bad year. Premium last, extras last.

And if it goes wrong, it is fixable. The window is three months from the day your coverage begins, and then every year after that.
