Medicare Advantage plans Nevada: who can join and when you can switch
Medicare Advantage plans in Nevada are private plans that replace your original Medicare. You can only join one if you have Medicare Parts A and B and the plan serves the area where you live. Most people can switch only on set dates, and those dates decide whether you are stuck for a year or free to change.
Below: who qualifies, the dates that matter, a 12-month trial for new enrollees, and what a plan cannot refuse you. This page explains the federal law. It does not rank plans or list insurers, because plans and prices change every year.
What to do first
You can choose a Medicare Advantage plan only if you are entitled to Part A and enrolled in Part B (42 U.S.C. 1395w-21(a)(3)). No Part B, no plan.
A plan is open to you only if it serves the area where you live (42 U.S.C. 1395w-21(b)(1)(A)). In Nevada that means it must cover your county. Moving out of the service area is a reason to change plans.
The plan must give you the benefits original Medicare gives under Parts A and B. Hospice care and organ acquisition costs for kidney transplants are the two exceptions, and those stay with original Medicare (42 U.S.C. 1395w-22(a)(1)). Plans may add extra benefits. The government must give you information on those extras and their premiums so you can compare (42 U.S.C. 1395w-21(d)).
Every switching right below runs off a date. Keep your plan's welcome letter and the date it started.
When you can join or switch
| Situation | Rule | Source |
|---|---|---|
| Yearly fall switching period | October 15 through December 7. A change made then starts January 1 of the next year. | 42 U.S.C. 1395w-21(e)(3)(B)(v); (f)(3) |
| Already in a plan, early in the year | During the first 3 months of the year you may change your election one time | 42 U.S.C. 1395w-21(e)(2)(G)(i), (ii) |
| Changes made in the first 3 months | Take effect on the first day of the next month | 42 U.S.C. 1395w-21(f)(2) |
| Newly eligible and joined a plan | You may also change once during the first 3 months you are eligible | 42 U.S.C. 1395w-21(e)(2)(G)(i)(II) |

Checked on November 14, 2026 against the United States Code, 2024 Edition, Title 42, sections 1395w-21 and 1395w-22. Some old transition dates in these sections apply only to past years. The dates above are the ones that apply to the current year and later years.
The first-3-months switch is one change, not unlimited
The early-year window lets you change once. After that you wait for the fall period. Choose carefully: if you swap plans in February and the new one is worse, the law gives you no second swap until the fall, unless a special reason applies (42 U.S.C. 1395w-21(e)(2)(G)(ii)).
Special reasons you can leave a plan outside the dates
You can leave a plan and choose another at any time of year when one of these happens (42 U.S.C. 1395w-21(e)(4)):
- The plan, or the company's approval to run it, is ending, or it has told you it will end.
- The plan stops serving the area where you live.
- You are no longer eligible because you moved or your circumstances changed.
- The company badly broke its contract with you. This includes not giving you medically necessary care on time.
- The company, or someone working for it, lied about the plan when selling it to you.
The last reason matters for anyone who bought on a sales call or at an event and later found the doctor or drug was not covered. You must be able to show what was said. Write the date, the name and what they promised.
What a plan cannot do to you
A Medicare Advantage company may not deny, limit or put conditions on your coverage because of a health factor. The government also may not approve a plan designed to discourage sick people from joining (42 U.S.C. 1395w-22(b)(1)).
A plan may not discriminate against a provider acting within their state license just because of the kind of license they hold (42 U.S.C. 1395w-22(b)(2)).
Mistakes that cost people a year
If you miss the fall period and no special reason fits, you generally wait for the next one, apart from the one change in the first 3 months.
Ask the doctor's office, not just the salesperson, whether they take that exact plan for the new year. Plans change networks every January.
Part B is what makes you eligible. Without it, the plan is not open to you at all (42 U.S.C. 1395w-21(a)(3)).
Programs and help that apply
Good to know
Before you choose, make a one-page list: your doctors, your pills, your pharmacy and the hospital you would want. Check each against the plan. A plan that looks cheap can cost more when your own doctor is outside it. Do this between October 15 and December 7, with time to spare.
