2027 Medicare Advantage Plan Changes: What to Do
Find your plan. Understand your notice. See your next step.
Find your current 2026 plan Optional
Use the name or plan ID on your insurance card or notice. This finds a 2026 listing, not a 2027 renewal decision.
Choose your state first.
For example, H1234_001_0. Do not enter your Medicare or member number.
The plan search needs JavaScript. No JavaScript is needed to read the notice guidance below.
Names can repeat. Compare the full contract, plan and segment ID with your documents; ask the plan if you cannot identify the segment.
Cannot find it? Check your card or notice, or call the plan to confirm its name and CMS ID. A missing match does not mean your coverage is ending.
Your selected 2026 listing
This matches a CMS listing, not your enrollment record. Use your notice below to check what happens next.
What does your notice say?
Your notice guides these next steps. The lookup does not confirm your 2027 coverage.
I’m not sure. Help me start.
See where to look on a notice
Your letter may look different. Some notices do not show the full plan ID.
A letter about your Medicare plan
Example Health Plan
H1234_001_0
Match your plan’s name and full CMS ID. This is not your Medicare or member number.
Look for a coverage-end date, a start date, or a deadline to respond.
Use your real notice. Not every letter includes all three dates.
Look under “Questions?” or “Member services.”
Cannot find an ID or date? Call your plan and ask.
More details
Plans send the Annual Notice of Change in September. It describes changes effective in January. Review it before the general October 15–December 7, 2026 enrollment window ends. A notice requiring action may give different dates.
Ask your plan whether coverage will renew, move to another plan, or end. Finding—or not finding—a listing does not answer that question.
No current plan selected. This guidance uses your notice only.
My plan is ending or leaving my county
Check these dates with your plan
- Your coverage-end date
- Any response deadline
- When your next coverage starts
Call your plan or Medicare before the notice deadline. December 7 may not be your only deadline.
More details
Ask which special enrollment period and coverage start date apply to you.
Confirm whether this is a nonrenewal, a service-area change, or a move to another plan. The options can differ; do not assume waiting keeps the same coverage.
No current plan selected. This guidance uses your notice only.
I will move to another plan automatically
Ask your plan to confirm
- Destination plan’s name and full ID
- Effective date of the move
- Any response deadline
More details
Check the destination plan’s costs, benefits, doctors, drugs and pharmacies. Medicare or SHIP can help you understand the choices.
A plan consolidation is different from a nonrenewal. Do not assume an automatic move gives you the same special enrollment options as a plan ending. This guide has not verified a destination plan for you.
No current plan selected. This guidance uses your notice only.
My plan continues—with or without changes
Review these four things
- Costs & benefitsPremiums and what you pay
- DoctorsAre your providers covered?
- DrugsCoverage and cost of each prescription
- PharmacyWhere you can fill prescriptions
Your costs or benefits can change even when your plan continues.

Read your Annual Notice of Change. Changed costs or benefits do not by themselves mean you must switch.
If you decide to change coverage, the general Medicare Open Enrollment window is October 15–December 7, 2026, for coverage starting January 1, 2027. The plan must receive your enrollment request by December 7. Ask Medicare about other enrollment periods if your circumstances differ.

The autumn enrollment window does not guarantee you can buy or switch a Medigap policy.

For a separate drug plan, read its Annual Notice of Change. The general October 15–December 7, 2026 window is for January 1, 2027 coverage.
Medigap supplements Original Medicare; its enrollment rules differ. For work coverage, use your benefits administrator’s dates. Changes may affect you or your dependents.
The current-plan lookup covers Medicare Advantage. These other coverage types are outside it; a missing match does not mean coverage is ending.

About the 2026 lookup and this guidance
The lookup identifies a listed plan, not your enrollment or your 2027 coverage. It includes 2026 Medicare Advantage (MA), Medicare Advantage with Part D (MA-PD), and Special Needs Plan (SNP) identities, with separate segments. SNPs have additional eligibility requirements.
It excludes stand-alone Part D, Cost plans and employer-sponsored plans. CMS also excludes Part B-only and national PACE plans. The county menu reflects this source's county listings; it is not a complete list of every geography or coverage option.

CMS has published its official 2027 plan crosswalk. This guide has not yet validated year-to-year plan changes from that file. Neither year's listings establish a renewal, termination, county exit or successor plan. Notice choices describe what you report; confirm your own situation with the plan or Medicare.

The general enrollment timeline
For changes made during Medicare Open Enrollment:
- Enrollment opensCompare coverage and make changes.
- Enrollment closesThe plan must receive your request by this date.
- New coverage startsFor changes made in this window.
Your notice may have different dates. If your plan ends, you move, or your circumstances change, ask Medicare which deadline and coverage start date apply to you. See Medicare’s enrollment guidance and special enrollment periods.
Before you choose coverage for January
- Read your plan’s Annual Notice of Change. It should arrive in September. If it is missing, ask your plan for a copy. A separate notice that your plan will not renew needs its own deadline check.
- Check your doctors, drugs and pharmacies for 2027. Confirm with the plan and your providers that the coverage you need will be available. Compare estimated yearly costs, including prescriptions and cost sharing, as well as premiums.
- Check other coverage before making a change. If you have employer, union or retiree benefits, contact the benefits administrator first. A change can affect your coverage or your dependents’ coverage.
- Confirm the new coverage start date. Keep the enrollment confirmation and make sure any medical and drug coverage you need starts on time. Returning to Original Medicare does not by itself guarantee that you can buy Medigap; check the separate Medigap rights and application rules.
Use Medicare’s yearly review guide and Medicare Plan Finder for your comparison. The public catalog on this page is a starting point; it cannot verify your enrollment, doctors or drug coverage.
Questions about your current plan
If my plan continues, do I have to enroll again?
Generally, no—if the plan confirms renewal and you want to keep it after reviewing next year’s costs and coverage. Check doctors, drugs and pharmacies too. Medicare’s yearly review guide can help.
What if I cannot find my plan?
A missing match does not mean your coverage is ending. Check your county and full plan ID, or call your plan. This lookup excludes employer plans, stand-alone Part D and Medigap.
Does the 2027 catalog prove my plan renews?
No. It lists plans for a county; it does not confirm your renewal, an automatic move, or eligibility to join. Confirm your situation with your plan or Medicare.
What if my Annual Notice of Change has not arrived?
Call your plan and request it. It should arrive in September and describe January changes. Read Medicare’s notice guidance.
Browse 2027 plans in your county
This is a catalog of plans listed for next year, not an answer about your current coverage. Start with your state and county, then narrow the listings by plan name, insurer, or CMS plan ID.
A missing plan is not proof that it ended. Read the source dates, scope, and limits or compare plans at Medicare.gov.
Choose your state first.
Example ID: H1234_001 or H1234_001_0. Search stays on this page. Do not enter a Medicare number or other personal information.
Use the lookup with JavaScript, or use Medicare Plan Finder and the CMS download below.
What this lookup includes and its limits
This lookup includes the landscape’s Medicare Advantage (MA), Medicare Advantage with Part D (MA-PD), and Special Needs Plan (SNP) listings. It excludes standalone Part D drug plans (PDP) and Cost plans. CMS says employer plans, Part B-only plans, and national PACE plans are outside this landscape’s scope.
The county menu covers counties named by county-scoped rows in this CMS landscape, including counties with Cost listings but no in-scope Medicare Advantage offerings. States and territories with no county-scoped rows remain in the state menu with an explicit limitation. The menu is not a complete inventory of every U.S. geography or every coverage option.
A missing plan is not proof that it ended. This tool does not classify terminations, consolidations, successor plans, insurer exits, county losses, or Medigap rights. CMS has published its official 2027 plan crosswalk. This guide has not yet validated year-to-year plan changes from that file. Read your plan’s notice and confirm your situation with Medicare.
Special Needs Plans have additional eligibility requirements. Sanctions may restrict enrollment. The capacity field is an accepted capacity amount, not current enrollment or remaining spaces. See Medicare’s Special Needs Plan guidance and its guidance on joining a plan.
