Medicare Advantage plans aren’t locked in forever. If your current plan raised premiums, dropped doctors from its network, or cut benefits you rely on, you have specific windows each year to switch to a better plan. Here’s exactly how the process works — and how to make sure you pick the right plan the second time around.
When Can You Switch Medicare Advantage Plans?
You can’t switch plans at any time of year. Medicare allows changes only during specific enrollment periods. Missing these windows means you could be stuck with your current plan for another year.
| Enrollment Period | Dates | What You Can Do |
|---|---|---|
| Annual Enrollment Period (AEP) | Oct 15 – Dec 7 each year | Switch MA plans, switch to Original Medicare, add/change Part D, enroll for the first time |
| Medicare Advantage Open Enrollment (OEP) | Jan 1 – Mar 31 each year | Switch from one MA plan to another, or drop MA and return to Original Medicare (one change only) |
| Special Enrollment Period (SEP) | Anytime (if qualifying event occurs) | Varies by reason — see below |
| Initial Enrollment Period (IEP) | 7-month window around 65th birthday | First-time enrollment in Medicare and/or MA |
What Qualifies as a Special Enrollment Period?
SEPs allow you to change plans outside the standard enrollment windows if a qualifying life event occurs. Common qualifying events include:
- Moving to a new address outside your plan’s service area
- Losing other coverage (employer plan, Medicaid, etc.)
- Gaining eligibility for Extra Help (Low Income Subsidy)
- Your plan leaves Medicare or stops serving your area
- Qualifying for Medicaid or a D-SNP
- Being released from incarceration
SEP windows are typically 60 days from the qualifying event, though some allow up to 3 months. Always confirm with Medicare or a licensed advisor as soon as a qualifying event occurs.

Review your current plan’s Annual Notice of Change (ANOC)
Every fall, your plan mails you an ANOC listing every change to premiums, copays, drug formulary, and benefits for the coming year. Read it carefully — this is often what triggers the need to switch.
List your priorities before you shop
Identify your top concerns: specific doctors you must keep, prescriptions you take regularly, dental or hearing needs, budget for monthly premiums, and how often you use out-of-network providers.
Use Medicare’s Plan Finder to compare options
Visit Medicare.gov/plan-compare and enter your zip code. Filter by plans that include your doctors and cover your drugs. Compare star ratings, out-of-pocket maximums, and extra benefits side by side.
Verify your doctors are in-network
Before enrolling in any new plan, call the plan directly or check its provider directory online to confirm your primary care doctor, specialists, and preferred hospital are in-network. Directories can be outdated, so a phone call is the safest verification.
Check your drug formulary
Every plan has a list of covered drugs (formulary) organized into tiers that determine your copay. Make sure all your regular medications are covered — and at a tier you can afford. Pay attention to step therapy requirements or prior authorization rules.
Enroll in the new plan before the deadline
You can enroll online at Medicare.gov, by calling Medicare at 1-800-MEDICARE, or by calling the plan directly. You can also have a licensed Medicare agent enroll you on your behalf. When you enroll in a new MA plan, your old plan is automatically terminated on December 31 — you do not need to cancel it separately.
What to Watch Out for When Switching
- Network disruption: Your current specialist may not be in your new plan’s network. Always verify before enrolling.
- Drug formulary gaps: A plan with a great premium may not cover your most expensive medications. Calculate total drug costs, not just premiums.
- Prior authorization rules: Some plans require pre-approval for procedures that your old plan covered automatically.
- Waiting periods for dental or vision benefits: New plans may not activate certain benefits until mid-year.
- Missing the deadline: If you miss the AEP (Dec 7) or OEP (Mar 31), you’re generally locked in until the next enrollment period.
Should You Switch or Stay?
Switching plans is worth it if your current plan has increased costs significantly, dropped key providers, cut benefits you use, or if you’ve found a plan with substantially better drug coverage or lower out-of-pocket costs. However, if your plan’s network, coverage, and costs are stable, staying put avoids the disruption of transitioning to a new plan.
The easiest way to decide is to have a licensed Medicare advisor compare your current plan against available alternatives in your area. This service is free, and a good advisor will only recommend switching if there’s a clear, documentable benefit to you.
Let us do the comparison for you. Our licensed advisors will analyze your current plan vs. available options and tell you honestly if switching makes sense.
