How does a Medicare Advantage plan work?

The short answer

An Advantage plan bundles your Medicare, your prescriptions and some extras into one plan with a low monthly cost. You pay as you use it, and there's a limit on what a bad year can cost you.

These are the plans you'll see called HMO or PPO.

A short story. It stops before the ending.

    The one picture to remember

    Four things in one plan, and a ceiling on the year.

    Low monthly cost. You pay along the way instead.

    How it works

    Six short cards. Open "Going deeper" only if you want the detail.

    The basic idea

    One plan does the whole job

    Instead of Medicare paying 80% and a second plan filling the gap, an Advantage plan takes over the job. You keep Medicare, and a private company delivers it — plus your prescriptions and some dental, vision and hearing coverage.

    That's why the monthly cost is low. It's the trade for how you pay later.

    What it costs monthly

    The monthly cost is the low part

    Plan premiumSome plans have no monthly premium. It varies by county.
    Varies by plan
    Your Part B premiumYou still pay this to Medicare. Every route includes it.
    $202.90 a month (2026)

    A plan with no monthly cost isn't free coverage. It means the cost arrives when you use it.

    How you pay

    You pay copays when you use it

    A copay is a set amount you pay for a visit, a test or a stay. Instead of one predictable monthly bill, your cost tracks how much care you actually need.

    Specialist visitEach visit
    Varies by plan
    Tests and imagingEach test — a scan costs more than lab work
    Varies by plan
    Hospital stayPer day, usually for the first several days
    Varies by plan

    Every plan sets its own amounts, and they differ by county. The plan finder on this site shows the real figures for the plans where you live.

    Where it bites

    The big things are where the copays add up

    Everyday care is cheap. A surgery, a hospital stay or cancer treatment is where a per-day hospital copay and a string of tests turn into real money — at the same moment you're least able to deal with it.

    That's the honest gap in these plans: you pay less up front, and if you actually end up using your coverage a lot, you come out of pocket more.

    The ceiling

    There's a limit on what one year can cost you

    Every Advantage plan has a yearly maximum. Once your copays reach it, the plan covers the rest of the year at 100%.

    Yearly maximumSet by the plan, within a legal ceiling
    Varies by plan

    This matters because Original Medicare on its own has no limit at all (step 1). A limit is real protection — and it's also real money you could be asked for in a bad year.

    Doctors

    These plans use networks, and come as HMO or PPO

    HMOStay inside the network, and you may need a referral to see a specialist.
    PPOYou can go outside the network, but it usually costs more.

    So before you pick one, the question is simple: are your doctors in it? Check your own doctors and prescriptions here — nothing is saved.

    Going deeper — prior approval

    Advantage plans can require the plan's approval before certain care goes ahead — scans, surgeries, rehab stays. Your doctor asks the plan first. Approvals are common, but it's a step Original Medicare with a Supplement doesn't have.

    It's the difference people notice most after a serious diagnosis, so it's worth asking about.

    Every year

    These plans can change each year

    Copays, the yearly maximum, the extras, the network and the drug list can all change for the coming year. Your plan mails you a notice each fall showing what's different.

    It's worth reading. The plan that fit you this year may not be the right fit next year, and fall is when you can change it.

    The extras

    Some dental, vision and hearing — with limits

    Most Advantage plans include some coverage for dental, vision and hearing, which Original Medicare doesn't cover at all. Plans may also include things like gym access or an over-the-counter allowance.

    Read these as a bonus, not full coverage: each one usually has a yearly dollar allowance, and a big dental job can use it up quickly.

    Try it

    Two quick tools. Nothing you pick is saved.

    Add up a year of care

    Tap the plus and minus to build a year, and watch what you'd pay.

    Specialist visits$50 each
    2
    Tests and scans$150 each
    1
    Nights in the hospital$400 a night
    0
    Outpatient surgeries$400 each

    What you'd pay this year $250

    Well under this example plan's $6,000 yearly maximum.

    A year with one big thing in it.

      You're going to pay for your coverage one way or the other. Either more each month and you're covered when you use it, or less each month and more out of pocket if something major happens.
