Medicare Advantage plans for 2026 are private Part C plans that bundle your Medicare benefits, usually with drug coverage and extras. Each year insurers change premiums, benefits, drug formularies and networks, so the plan that was best for you last year may not be best for 2026. The smart move is to compare your current plan against this year options during the Annual Enrollment Period, October 15 to December 7.

Open the calculatorWhat is changing for 2026
Medicare Advantage is refreshed every plan year. Heading into 2026, the things most likely to affect you are:
- Plan lineups shift. Insurers add, drop and redesign plans, so some plans available in 2025 will not be offered in 2026.
- Premiums and copays move. A plan that was $0 can change its cost sharing, and a higher-premium plan can become more competitive.
- Drug coverage changes. The Part D formulary and out-of-pocket drug costs are updated, which matters if you take regular prescriptions.
- Extra benefits are retuned. Dental, vision, hearing, OTC and fitness perks are adjusted plan by plan.
- Networks update. Providers join or leave plan networks, so confirm your doctors are still in network.
Every fall your plan mails an Annual Notice of Change that lists exactly what is different for the coming year. Read it before you decide to stay or switch.
What Medicare Advantage plans cost in 2026
The premium is only one piece. Your real 2026 cost is the sum of several parts:
| Cost piece | What it means for 2026 |
|---|---|
| Plan premium | Often $0, but check what the low premium trades off in copays. |
| Part B premium | You still pay the standard Part B premium to Medicare even on a $0 plan. |
| Deductibles | Medical and drug deductibles before the plan starts paying its share. |
| Copays and coinsurance | Per-visit costs that add up if you use a lot of care. |
| Out-of-pocket maximum | Your yearly ceiling on covered medical costs. Medicare sets a federal cap and plans can set lower ones. |
To see these added together for your situation, use our Medicare Advantage cost calculator, then check your worst case with the out-of-pocket maximum calculator.
How to compare 2026 plans the right way
Use the same four checks for every plan you consider:
- Network: confirm your doctors and preferred hospital are in network.
- Drugs: check that your prescriptions are on the formulary and see their tier and cost.
- Total cost: add premium, expected copays and the out-of-pocket maximum, not just the premium.
- Extras that you will actually use: dental, vision, hearing or OTC benefits only count if they fit your needs.

When you can choose a 2026 plan
The main window to pick or change a 2026 Medicare Advantage plan is the Annual Enrollment Period, October 15 to December 7, with coverage starting January 1. Current Advantage members get a second window, the Medicare Advantage Open Enrollment Period, from January 1 to March 31. See our enrollment periods guide for the full rules and deadlines.

FAQs
What is the best Medicare Advantage plan for 2026?
There is no single best plan for everyone. The best 2026 plan for you is the one whose network includes your doctors, whose formulary covers your prescriptions, and whose total expected cost is lowest for how you actually use care. Compare plans in your ZIP code on the official Medicare Plan Finder.
What is going to happen to Medicare Advantage plans in 2026?
Plan availability, premiums, benefits and networks change as insurers file new plans for 2026. Some plans are discontinued or change their extras and drug coverage, so review your Annual Notice of Change each fall and compare options during the Annual Enrollment Period from October 15 to December 7.
What is the biggest disadvantage of Medicare Advantage?
The biggest disadvantage is restricted provider networks combined with prior authorization on some services. Care outside the network can cost much more or may not be covered, and switching back to Original Medicare later can trigger Medigap medical underwriting in most states.
Are seniors losing their Medicare Advantage plans?
Each year some plans are discontinued or leave certain areas, so a portion of members must choose a new plan. If your plan is ending you receive a notice and qualify for a Special Enrollment Period to pick a new plan or return to Original Medicare. Always read the fall notices from your plan.
