There is no single best Medicare Advantage plan, and anyone who tells you otherwise is selling something. Plans are sold county by county, the networks differ street by street, and the plan that is excellent for your neighbor can be a poor fit for you if your cardiologist is out of network.
What we can do is show you the 2026 numbers, explain what separates a good plan from a bad one, and walk you through comparing them yourself in about twenty minutes.
What Medicare Advantage is
Medicare Advantage, also called Part C, is private insurance that replaces Original Medicare. The insurer is paid by Medicare to cover everything Parts A and B cover, and most plans add prescription drug coverage plus extras that Original Medicare does not include.
You are still in the Medicare program and you still pay your Part B premium. What changes is who administers your care and what rules apply.
The 2026 numbers you need
These come from the Centers for Medicare and Medicaid Services, which published the official figures in November 2025.
The standard Part B premium is $202.90 per month in 2026, up $17.90 from $185.00 in 2025. You pay this whether you choose Original Medicare or Medicare Advantage. A plan advertising a $0 premium means $0 on top of that, not free coverage.
The Part B annual deductible is $283, up $26 from $257 in 2025.
The Part A hospital deductible is $1,736 per benefit period, up $60. Most people pay no Part A premium because they worked 40 quarters. If you did not, the 2026 premium is $311 or $565 monthly depending on your work history.
The Part D out-of-pocket cap is $2,100 in 2026, up from $2,000. Once your covered drug spending reaches it, you pay nothing for covered drugs the rest of the year. If you take expensive medication, this is the single most important number on this page.
The maximum Part D deductible is $615.
Higher earners pay a surcharge called IRMAA on top of the Part B and Part D premiums, calculated from your tax return two years earlier. For 2026 premiums, that means your 2024 income.
The real trade-off
Medicare Advantage usually costs less month to month and bundles benefits. Original Medicare costs more in premiums but imposes fewer restrictions.
Advantage plans use networks. Going outside the network is expensive or not covered at all. Many require referrals to see specialists, and most require prior authorization for expensive procedures, which means the insurer decides whether a treatment is covered before it happens.
Original Medicare is accepted by nearly any provider in the country that takes Medicare, with no referrals and no prior authorization. But it has no cap on your out-of-pocket costs, which is why most people pair it with a Medigap policy, and that policy has its own monthly premium.
One detail that matters more than people realize: Advantage plans are required to cap what you pay in network each year. Original Medicare alone is not. That cap is the strongest argument for Advantage, and its size varies by plan, so check it.
How to actually compare plans
Use the official Medicare Plan Finder at medicare.gov. It is free, it shows every plan available in your ZIP code, and it is not run by an agent earning commission.
Enter your medications first. Every drug, with dose and quantity. The tool then shows your estimated total annual cost per plan, which is the only number worth comparing. A plan with a lower premium and a worse drug formulary can cost you thousands more.
Check your doctors individually. Do not rely on the plan’s directory alone, because directories are frequently out of date. Call each doctor’s billing office and ask whether they accept that specific plan for the coming year. A hospital being in network does not mean the anesthesiologist working there is.
Look at the out-of-pocket maximum, not the premium. That is your worst-case year.
Read the star rating. Medicare rates plans from one to five stars based on member experience and outcomes. It is not perfect, but consistently low ratings are a real warning.
Check the extras honestly. Dental, vision and hearing benefits are the main selling point of Advantage plans, and they are also where the marketing is loosest. A dental benefit with a $1,000 annual maximum will not cover an implant. Read the actual limit before it influences your decision.
Enrollment deadlines
Initial Enrollment Period. Seven months around your 65th birthday: the three months before, your birthday month, and the three months after.
Annual Enrollment, October 15 to December 7. This is when most people switch. Changes take effect January 1.
Medicare Advantage Open Enrollment, January 1 to March 31. If you are already in an Advantage plan, you get one chance to switch to a different one or return to Original Medicare.
Special Enrollment Periods open outside those windows if you move, lose other coverage, or your plan leaves your area.
One warning that costs people dearly: if you leave Medicare Advantage for Original Medicare after your initial window, insurers in most states can medically underwrite a Medigap policy, meaning they can charge you more or refuse you outright based on your health. The door back is not always open.
Before you enroll, do this
Contact your State Health Insurance Assistance Program, known as SHIP. Every state has one, the counseling is free, and the counselors are not paid by insurers. They will sit with you and compare plans without a commission at stake.
And review your plan every single year, even if you are happy. Formularies change, networks drop providers, and benefits get trimmed. The plan that was right last year may not be right in January.
