Medicare open enrollment runs from Oct. 15 to Dec. 7. It’s your chance to review your Medicare plan to see whether it’s changing and what else might be available.
Here’s how to check on your current coverage and potentially make a change during open enrollment.
Step 1: Read your Annual Notice of Change
You’ll get an Annual Notice of Change (ANOC) in the mail by Sept. 30 — shortly before open enrollment starts.
The ANOC describes how your plan will change for the coming year.
Changes to look for in your ANOC
Costs Premiums, deductibles, copays, coinsurance and maximum out-of-pocket amounts.
Medical benefits Coverage for health care and services, plus which doctors and/or hospitals are in-network.
Medications Which prescription drugs are covered and what they'll cost out of pocket.

| 48 states and Washington, D.C. | Medium (50% to 84%) | 3.74 (Average) | ||
| 46 states and Washington, D.C. | Low (49% or less) | 3.82 (Above average) | ||
| 43 states and Washington, D.C. | Medium (50% to 84%) | 3.89 (Above average) | ||
| 29 states and Washington, D.C. | Medium (50% to 84%) | 3.96 (Above average) |
Step 2: Identify your needs
Think back on how your Medicare plan worked for you over the past year.
- Costs: Were the premiums, deductibles, copays and/or coinsurance affordable?
- Benefits: Did it cover the care and services you needed?
- Networks: Were you able to use the right doctors, hospitals and/or pharmacies?
- Medications: Were your medications available and affordable?
Take a look at your ANOC, too. Will upcoming changes to your plan make the plan a better or worse fit?
Based on your experience and your needs, identify what you most want out of a plan. You could make a list of a few top priorities.
Example priority lists
Choose a tab based on the kind of Medicare coverage you have.
- My doctors and hospital are in-network.
- Star rating of 4 stars or better (out of 5 stars).
- My medications are covered with affordable copays.
- $0 premiums.
Step 3: Shop for your best plan
With your priorities and your plan’s upcoming changes in mind, you can work on comparing options. Your current plan might be the best option, but it’s possible there’s another plan that’s a better fit.
For example, if your plan is getting more expensive, you can look for lower premiums. Or if the provider network is changing, you can search for plans that will cover your doctor.
You’ll probably have many options available during open enrollment. The average Medicare beneficiary had 42 unique Medicare Advantage plan options to choose from for 2025, for example. That’s according to a 2024 analysis by KFF, a health policy nonprofit.
Use reviews and shopping tools to compare the options available to you and find the best fit.
Step 4: Sign up
Once you’ve made a decision, you can make changes during open enrollment. Medicare open enrollment starts on Oct. 15 and runs through Dec. 7.
Switching plans
If you’re switching plans, you can sign up in several ways:
- Online: You can use Medicare.gov, an independent comparison site or an insurance company’s website to browse and sign up for plans.
- By phone: You can call 800-MEDICARE (800-633-4227; TTY 877-486-2048). Brokers, agents and insurance companies can also help you sign up by phone.
- On paper: You can ask the insurance company for a paper form, which you’ll have to get back to them by the end of open enrollment.
Keeping your plan
If you’ve decided to keep your plan, you shouldn’t need to sign up again during open enrollment. (You can confirm this by checking the section in your ANOC that starts with “If you want to stay…”)
